Description

Test false vehicle and automatic emergency braking test system Technical Field The utility model relates to the technical field of intelligent network connection automobile testing, in particular to a brake lamp simulation device. Background With the development of intelligent vehicle technology, automatic emergency Braking systems (ADVANCED EMERGENCY Braking systems, AEBS) for vehicles have emerged. The AEBS system detects road condition information such as obstacles (pedestrians, vehicles ahead and the like) in front of the vehicle by means of sensors such as vehicle-mounted radar and cameras, and then calculates collision risk by an electronic control unit (Electronic Control Unit, ECU). If a potential collision risk is detected, the AEBS system can send out an early warning to remind a driver to take measures to avoid collision, and when the driver does not take braking or does not take an obstacle avoidance operation, the AEBS system controls the vehicle to start emergency braking operation to assist the driver to avoid the potential collision risk, so that driving safety is improved. Since the performance of the vehicle to start the emergency braking under different road conditions is different, in order to ensure the reliability of the automatic emergency braking performance of the vehicle (i.e., the performance of automatically starting the emergency braking by the AEBS system), it is necessary to test the automatic emergency braking performance of the vehicle under different road conditions. However, since the test of the automatic emergency brake AEB has a certain risk, in order to prevent collision damage, an air-filled dummy vehicle or a foam dummy vehicle is used in front of the automatic emergency brake test vehicle. However, since the existing automatic emergency braking test vehicle is an air or foam filled vehicle, the difference between the air or foam filled vehicle and the real vehicle is large, and the automatic emergency braking system cannot accurately identify the test vehicle.
