| 摘要： | A 2021 model year vehicle is in your shop for brake work. The car has an advanced driver assistance system (ADAS) that includes automatic emergency braking (AEB) and traction control. All four rotors look serviceable, but the brake pads are worn and you replace them with an inexpensive af-termarket pad (OEM pads are too expensive). Will your choice of brake pads cause an unhappy customer leading to a comeback, an accident, or even legal problems for your shop? The customer picks up his vehicle, drives off and becomes distracted as he approaches a red light at a busy intersection. He fails to apply the brakes in a timely manner, but the ADAS attempts to come to the rescue. The ADAS uses radar/lidar to determine that the vehicle is not slowing sufficiently to avoid hitting a vehicle stopped in the intersection, so it commands the brakes, through the automatic emergency braking system, to apply braking force. The car starts to slow - but not enough - and it hits the other vehicle. Why did the AEB system fail? |
