The EV-360_035325 was designed to demonstrate the fundamental safety concepts and technologies currently incorporated in today’s advanced vehicles. Instead of using a complex proprietary large vehicle that would require manufacturer equipment, scan tool, support, and programming, we have developed a generic trainer with programming specifically adapted to an educational envi- ronment. The trainer is a scale model, providing visual cues of where the components are typically found on an actual vehicle, helping the students to recognize design function and orientation. The trainer is also designed to be used in conjunction with real vehicles as it augments practical hands-on learning. By removing the obstructions, complexity and non-relevant vehicle systems, your students will be able to focus solely on ADAS and autonomous technology. This trainer allows a student to visualize sensor readings and results, literally locating where the components are on a vehicle and compares the strengths and weaknesses of the various sensors and technologies to one another. The stu- dent becomes the processor of all the sensor inputs to experience “sensor fusion”, or the process of interpreting all of the information into a desired outcome or reaction. Because most have limited experience with ADAS technology, this product is designed for assisting the teacher explain how the technology works as well as for teaching the students why ADAS works. Side View of the EV-360_035325 ADAS Trainer consulab.com info@consulab.com 4 91-EV-360 Introduction ADAS Sensor Theory ADAS stands for Advanced Driver Assistance Systems. It refers to a set of technologies and features in modern vehicles designed to enhance safety, comfort, and convenience for the driver and passengers. ADAS systems use sensors such as cameras, RADAR, and LiDAR, to detect and respond to driving conditions and situations. The goal of an ADAS system is to assist the driver in various driving scenarios, reduce the likelihood of accidents, and improve the overall driving experience. ADAS systems are becoming increasingly common in modern vehicles and are seen as a key technology in the development of autonomous vehicles. Examples of Advanced Drivers Assistance Systems include: • Adaptive Cruise Control • Lane Departure Warning • Blind Spot Detection • Forward Collision Warning • Automatic Emergency Braking • Rear-view Cameras • Park Assist • Automatic High Beams • Lane Keeping Assistance consulab.com info@consulab.com 5 91-EV-360 Introduction Basic Operation LiDAR LiDAR stands for “Light Detection and Ranging”. It’s a remote sensing technology that uses laser light to measure distances. The LiDAR system emits laser pulses which bounce back off objects and are captured by a sensor, allowing the system to calculate distances and generate a 3D representation of the environ- ment. It’s widely used in fields such as self-driving vehicles, robotics, surveying, and geography. RADAR RADAR stands for “Radio Detection and Ranging”. It’s a technology that use radio waves to determine the range, speed, and other characteristics of objects at a distance. RADAR works by emitting a radio frequen- cy signal and analyzing the reflection back of that signal off of an object to determine its range, velocity, and other characteristics. RADAR is widely used in applications such as weather forecasting, air traffic control, military surveillance, and self-driving vehicles. BLIND SPOT DETECTION Blind Spots Detection is a driver assistance technology that alerts the driver to the presence of vehicles in their blind spots. Blind spots are areas around a vehicle that are not visible to the driver through the side mirrors or the rear-view mirror. Blind spot detection systems use sensors, such as radar or cameras, to detect the presence of vehicles in these areas and provide the driver with a warning, such as a visual or auditory alert. This technology is aimed at reducing the risk of accidents caused by vehicles not being seen in the driver’s blind spot and is commonly found in modern vehicles. ULTRASONIC SENSORS Ultrasonic Sensors are devices that uses high-frequency sound waves to measure distance, speed, or detect the presence of objects. The sensor transmits an ultrasonic pulse, which bounces back off an object and is received by the sensor. The time it takes for the pulse to travel to the object and back is used to calculate the distance to the object. Ultrasonic sensors are commonly used in applications such as robotics, industrial automation, and distance measurement. OBJECT DETECTION Object Detection is a technology that allows a computer or machine to identify objects within an image or video. It involves analyzing digital images or videos and locating and classifying objects of interest, such as people, vehicles, buildings, etc. Object detection algorithms typically use techniques from computer vision, such as image processing, pattern recognition, and machine learning to perform this task. This technology is widely used in applications such as self-driving vehicles, surveillance, and video analytics. consulab.com info@consulab.com 6 91-EV-360 Introduction STEERING WHEEL ANGLE Steering Wheel Angle refers to the steering wheel’s angle of rotation in a vehicle. It is the amount by which the steering wheel is turned to the left or right and is a measure of the degree the front wheels turn. The steering wheel angle is an important input in modern vehicles, as it is used by various systems such as the power steering, stability control, self-parking, back up camera path prediction and traction control systems to determine the direction of the vehicle and to control its handling and stability. Steering wheel angle sensors are typically used to measure the angle of the steering wheel and provide this information to the vehicle’s control systems. DRIVER PRESENCE DETECTION Driver Presence Detection is a technology used in vehicles to determine if the driver is present and attentive. It typically uses sensors, such as cameras or biometric sensors, to detect the presence and behavior of the driver. The technology can be used to prevent accidents caused by drivers who are not paying attention, such as drowsy or distracted drivers. Driver presence detection systems can also be used to adjust the vehicle’s settings based on the driver’s preferences and habits. For example, a vehicle equipped with driver presence detection may adjust the seat, mirrors, and entertainment system based on the driver’s profile. INERTIAL MEASUREMENT UNIT (IMU) Attitude is information about an object’s orientation in relation to a horizontal plane and true north. The technology used in vehicles to detect attitude, such as pitch, roll, and yaw, is typically called an Inertial Measurement Unit (IMU). An IMU is a sensor system that consists of accelerometers, gyroscopes, and sometimes magnetometers. These sensors work together to measure the acceleration, angular velocity, and orientation of a vehicle. Yaw is referred to as the angular measurement on a horizontal plane with respect to true north, The angular measure- ment on the vertical plane, is referred to as pitch or roll. YAW PITCH ROLL Z Axis X Axis Y A xis consulab.com info@consulab.com 7 91-EV-360 Introduction Accelerometers measure the linear acceleration of the vehicle in the X, Y, and Z-axes. This information is used to de- termine the pitch, roll, and yaw of the vehicle. Gyroscopes measure the angular velocity of the vehicle, which provides information about the orientation of the vehicle and its rate of change. Magnetometers are sometimes used in combina- tion with accelerometers and gyroscopes to provide a more accurate measurement of the vehicle’s orientation, espe- cially when the vehicle is in motion. The sum of all this data provided by the IMU is processed by the vehicle’s control system to determine the attitude of the vehicle. This information is then used to control various systems in the vehicle, such as the suspension, stability control, and traction control systems. IMUs are widely used in vehicles. They are a key component in advanced driver assistance systems (ADAS) and autonomous vehicles. SENSOR FUSION Sensor Fusion refers to the process of combining data from multiple sensors to produce a more comprehensive and accurate representation of the environment. In the context of autonomous vehicles, sensor fusion is used to gather data from a variety of sensors, such as cameras, LiDAR, RADAR, ultrasonic sensors, and IMUs, and combine this information to create a single, unified understanding of the vehicle’s surroundings. The goal of sensor fusion is to overcome the limitations of individual sensors and to provide a more robust and reli- able perception of the environment. For example, cameras are good at recognizing objects and textures, but they can be affected by lighting conditions and have limited range. LiDAR provides high-resolution 3D data but is expensive and can be affected by fog or rain. RADAR provides long-range data but has lower resolution. By combining the data from multiple sensors, sensor fusion can provide a more complete and accurate view of the envi- ronment, which is essential for autonomous vehicles to make safe and confident decisions. The process of sensor fusion typically involves the use of algorithms and techniques from computer vision, machine learning, and robotics to process and analyze the data from the sensors and produce a unified representation of the environment. 91-EV-360 Introduction consulab.com info@consulab.com 8 Educational Advantages This trainer allows student to visualize sensor readings and results, literally locating where the components are on a vehicle, and compares the strengths and weaknesses of the various sensors and technologies to one another.

This exercise is step seven in understanding the accuracy of ADAS components in relation to the calibration process. There are two calibrations to consider – the accuracy of the sensor itself and the required position or aim of the sensor as it relates to contributing accurate information to allow correct ADAS operation. This assignment compares the sensor reading to an actual measurement. Using the EV-360 trainer, open each component on the tablet and verify accuracy of the distance measured by the sensor to a stationary target. Then compare that measurement to the actual distance using a tape measure. Record your results below. ADAS Input Component Distance provided by Sensor Actual Measured Distance Difference (if any) S2 LiDAR S3 Front RADAR S4 Ultrasonic L / F S5 Ultrasonic R / F S10 Blind Spot RADAR L / S S11 Blind Spot RADAR R / S S13 Ultrasonic L / R S14 Ultrasonic R / R 91-EV-360 Student Assignment - SA-8 Answers consulab.com info@consulab.com 18 SA-8 Understanding Steering Angle Calibration - Answers This exercise is step eight in understanding the accuracy of the steering angle in relation to the calibration process. This assignment will illustrate the importance of the steering angle calibration and how incorrect calibration can affect ADAS operation. Using the EV-360 trainer, open the Steering Angle Calibration mode on the tablet and follow instructions in the chart below, recording your observations Calibration Process Rear Camera Projection Vehicle ADAS Function Perform steering calibration, turning steering wheel correctly to L & R lock as instructed on tablet screen. How well does the rear camera’s path projection follow the steering wheel? The path moves exactly with the steering wheel, beginning and ending movement with the wheel movement. What is the purpose of the rear cam- era path projection ADAS feature? In addition to proper rear and side view mirror usage, this feature safely predicts the path the vehicle will follow in reverse, avoiding a collision with other vehicles or objects, assist- ing in parking operations especially. Re-calibrate, but this time do not turn the steering FULL L & R, instead hold mid-way and let it calibrate to that position. How well does the rear camera’s path projection follow the steering wheel? The path moves only partially with the steering wheel, stopping at the point of calibration. The steering wheel can continue to rotate to full stop, but the path will not follow. How would this affect ADAS? Relying on just the projected path while in reverse, this incorrectly calibrated path will not follow the steering in reverse, allowing a pos- sible collision with other vehicles or objects. 91-EV-360 Trainer Set-up consulab.com info@consulab.com 19 EV-360 Set-up for Student Assignments IMPORTANT: One time trainer set up required for SA-9 to SA-14: Conditions Required Animation Link 1.

Where is the area located that the Blind Spot Detectors are designed to warn drivers? On either side of vehicle, but actually in the lane next to the one occupied by driver. 2. What other technology is commonly used in blind spot detection? Cameras, Radar, and GPS. 3. Where can all BSD be located on a vehicle? Usually in both rear bumper corners and in both outside view mirrors. 4. Using the ENTRANCE or EXIT points previously marked on the lane markers, how many feet would a BSD that is aimed ½” (1 cm) (1 cm) off affect the accuracy of its warning? Approximately 2-3 feet (0.5 - 1 metre). 5. In feet (meters) per second, how fast is a vehicle travelling at 60 MPH (100km/h)? 60 X 5280 (feet per mile) divided by (60 X 60) = 88 feet per second. 100 × 1000 (metres per kilometre) ÷ (60 × 60) = 27.8 metres per second (m/s) 6. Regarding blind spot detection, how many feet (metres) per second is a vehicle passing you at a speed 10 MPH (20 km/h) faster than you are travelling? 10 X 5280 (feet per mile) divided by (60 X 60) = 14 feet per second. 20 × 1000 (metres per kilometre) ÷ (60 × 60) = 5.6 metres per second 7. At any speed, if a BSD is aimed ½” (1 cm) (1 cm) off, how would that affect the accuracy? The warning zone will shift forward or backward by approximately 2–3 feet (1 metre) or more the farther the ap- proaching vehicle is from the sensor (see question 4). This means the alert will not accurately represent the true blind spot, which does not change. 91-EV-360 Student Assignment - SA-10 consulab.com info@consulab.com 25 SA-10 Understanding Front Facing RADAR Calibration NOTE: Initial EV-360 SA-9−14 Set-Up must be performed FIRST (See EV-360 Set-up for Student Assignments).

How large is the Front Facing RADAR detection area designed to warn drivers? Students will have to calculate the area of a triangle, or one half of the base times height: AREA = 1/2 X (BASE X HEIGHT) 2. What other technology is commonly used in Front RADAR detection? Front facing cameras, LIDAR, multiple radar. 3. Where can a Front RADAR be physically located on a vehicle? Typically mounted in the front grille or front and rear bumper covers. 4. Using the LEFT and RIGHT points previously marked on the lane markers, how many feet (metres) would a RADAR that is aimed ½” (1 cm) off Left or Right affect the accuracy of its view? Answers will vary. It would shift the entire detection area off by 3 feet (1 metre) or more, making it less accu- rate further away from the vehicle. 5. At 100’ (30 m) out in front of the vehicle, how far off in feet is the RADAR accuracy if it is aimed incorrectly UP or DOWN by ½” (1 cm)? Answers will vary. Students should recognize that even a small aiming error can create a much larger position error as distance increases. The farther an object is from the RADAR sensor, the greater the resulting detection error. 6. In feet (metres) per second, how fast is a vehicle travelling at 10 MPH (20 km/h)? 14 feet per second (5.6 m/s). 7. In feet (metres) per second, how fast is a vehicle travelling at 25 MPH (40 km/h)? 30 feet per second (11.1 m/s). 8. In feet (metres) per second, how fast is a vehicle travelling at 45 MPH (70 km/h)? 60 feet per second (19.4 m/s). 9. In feet (metres) per second, how fast is a vehicle travelling at 60 MPH (100 km/h)? 88 feet per second (27.8 m/s). 10. How much would 1º of miscalibration affect ADAS lane departure operation? Just one degree of misalignment can cause the average-sized vehicle with lane departure warning to leave its lane within 180 feet (55 metres). 91-EV-360 Student Assignment - SA-11 consulab.com info@consulab.com 28 SA-11 Understanding LiDAR Calibration NOTE: Initial EV-360 SA-9−14 Set-Up must be performed FIRST (See EV-360 Set-up for Student Assignments).
