Abstract

The invention discloses a test device for calibrating a lateral coming vehicle by a head-on collision prevention system. The head-on collision prevention system comprises a control system, a radar arranged on a test vehicle and a vehicle passive safety control device; the test device comprises a simulated object positioned at the periphery of the test vehicle; the control system is provided with at least four control stages, namely a normal stage, a tracking stage, a prewarning stage and a collision buffering stage, and at least four corresponding instruction signals; the simulated object is a lateral coming vehicle simulation plate; the size of the simulation plate is the same as that of an actual vehicle; a vehicle lateral image is arranged on the surface of the simulation plate; and the simulation plate does motion along a direction vertical to a running direction of the test vehicle right in front of the test vehicle under the driving of a driving device. Therefore, the simulation plate can be effectively used for simulating the front lateral coming vehicle, so that traffic accidents easily caused by calibration by using a real vehicle and a real person are avoided, and the safety of testers is guaranteed effectively.

Description

technical field [0001] The invention relates to a test method and glue device of an automobile active safety system, in particular to a test method and device for calibrating lateral oncoming vehicles of an anti-collision system. Background technique [0002] As a new star of active safety technology, anti-collision technology has become a must-have strategic technology for current automobile companies because it can effectively prevent cars from colliding or reduce the collision intensity. If the calibration is not good, not only can it not avoid accidents, but it will cause annoyance to the drivers and passengers due to a large number of misjudgments. To achieve the effect of avoiding accidents, the calibration of the system needs to detect the vehicles in front of the vehicle, oncoming vehicles, side vehicles, pedestrians in front, pedestrians on the side, vehicles and pedestrians around the vehicle lane change, vehicles and pedestrians around the vehicle turning, etc. P...
