VEHICLE COLLISION DETECTION METHOD AND VEHICLE CONTROL SYSTEM

A vehicle collision detection method and a vehicle control system. Said method comprises: detecting a relative distance between a vehicle and an obstacle; determining whether the relative distance is less than a preset distance threshold, and if so, acquiring a longitudinal acceleration component and a lateral acceleration component of the vehicle within a first specified time duration; determining a first variance of the longitudinal acceleration component and a second variance of the lateral acceleration component; and if the first variance exceeds a preset first threshold or the second variance exceeds a preset second threshold, determining that a collision accident happens to the vehicle.
