Abstract

The invention discloses a low-cost bicycle rider collision test device for an AEB system. The low-cost bicycle rider collision test device for the AEB system comprises a bicycle rider model, a speed control module, a wireless stopwatch module, trigger signal sensors, a wireless transmitting module and a wireless receiving module; the bicycle rider model comprises a dummy model, a modified bicycleand an electric slide plate; the speed control module is used for controlling the speed of the electric slide plate; the wireless stopwatch module is used for recording the speed of the modified bicycle in real time; the trigger signal sensors are arranged at preset triggering positions on the two sides of a running route of a test vehicle; the wireless transmitting module is used for receiving induction signals of the trigger signal sensors and sending a starting signal to the wireless receiving module; and the wireless receiving module is used for receiving the starting signal and controlling the starting of the electric slide plate. The invention further discloses a bicycle rider collision test method for the AEB system. The bicycle rider collision test device for the AEB system is lowin cost, easy to assemble, firm in structure and easy to be popularized; and the bicycle rider collision test method for the AEB system is simple and convenient, multiple tests can be carried out, andtesting results are reliable.

Description

technical field [0001] The invention relates to the technical field of automobile auxiliary function testing, in particular to a low-cost AEB system cyclist collision testing device and a testing method thereof. Background technique [0002] The AEB system is the emergency braking system. It uses radar to detect the distance from the vehicle in front or the vulnerable road user, and analyzes it through the ECU. It gives an alarm according to different distances and speeds. If the alarm shows that the driver behind is not Without any reaction, the AEB system will activate when the safe distance is less than the range, and automatically intervene in the braking system of the car, thereby reducing the probability of collision with the vehicle in front / vulnerable road users. The AEB system has a great effect on improving vehicle safety. According to the research data of the Insurance Institute for Highway Safety, AEB can reduce traffic accidents by 27%. From 2016, Euro-NCAP tes...
