Abstract

The invention provides a vehicle BSD signal test device, which comprises a sealed box body, one group of side plates of the sealed box body are provided with an opening I corresponding to a vehicle rearview mirror and an opening II used for installing an auxiliary light source, the opening I is provided with a flexible lining used for preventing light leakage, a back plate of the sealed box body close to a vehicle tail direction is provided with an opening III, and the opening III is provided with a flexible lining used for preventing light leakage. A first shielding plate is hinged to the third opening, a moving mechanism is fixedly arranged on the inner wall of the first shielding plate, and an optical camera is installed on the moving mechanism. The outer wall of the sealed box body is fixedly connected with a fixing support used for fixing the box body to the outer wall of a vehicle body. According to the vehicle BSD signal testing equipment and the testing method, effective identification of BSD signals in automatic driving road testing is achieved, and the vehicle BSD signal testing equipment and the testing method have the advantages of being free of external environment interference, capable of achieving multi-parameter self-defined adjustment, high in identification accuracy, stable and efficient in signal output, convenient and fast to install and universal in vehicle types.

Description

technical field [0001] The invention belongs to the technical field of automatic driving vehicle testing, and in particular relates to a vehicle BSD signal testing device and a testing method. Background technique [0002] With the continuous development of autonomous driving technology, vehicles equipped with L2-level autonomous driving systems are gradually mass-produced and popularized, which brings great convenience to daily driving, but also puts forward new requirements for the testing and certification of automotive active safety functions. BSD (Blind Spot Detection, Blind Spot Detection) is one of the advanced driver assistance system (ADAS) technologies, which can monitor whether there are pedestrians or other vehicles in the blind spot of the vehicle, and alert the driver by means of alarms, so as to avoid traffic accidents. occur. [0003] At this stage, the test equipment is relatively simple, and the BSD signal is identified only by fixing the optical camera in...
