Two-vehicle collision test system and collision control method

The invention is suitable for the technical field of vehicle collision tests, and provides a two-vehicle collision test system and a collision control method, and the system comprises an upper computer, a PLC controller, a first traction device and a second traction device. The upper computer is used for receiving test parameters input by a user and sending the test parameters to the PLC; and the PLC is used for calculating traction parameters and traction duration of the two vehicles according to the test parameters, and sequentially controlling the first traction device and the second traction device to perform traction acceleration on the two vehicles according to the traction parameters and the traction duration of the two vehicles, so that the two vehicles simultaneously reach a preset collision point. According to the invention, the two vehicles can be controlled to complete multi-angle collision at the preset collision point, the test precision is high, and the accuracy of vehicle safety detection is i
