The invention provides a calibrating method and a calibrating device of a self-adaptive cruise system control parameter. The method can quickly and exactly acquire the self-adaptive cruise system control parameter through acquiring driving data of this vehicle and driving data of a vehicle in front, using the driving data of this vehicle and driving data of the vehicle in front as input variables;inputting to a deep neutral network model generated by pre-training; visibly, the deep neutral network model generated by pre-training can use this vehicle driving data capable of reflecting this vehicle driving condition from many aspects, and the front vehicle driving data capable of reflecting the front vehicle driving condition form many aspects as input variables, and further automatically output the corresponding self-adaptive cruise system control parameter, so that this vehicle acceleration value required to making this vehicle and the front vehicle enter a stable state can be accurately calculated; the calibrating speed and accuracy of the self-adaptive cruise system control parameter are effectively improved.
Description
technical field [0001] The invention relates to the technical field of automotive electronics, and more specifically, relates to a method and device for calibrating control parameters of an adaptive cruise system. Background technique [0002] The adaptive cruise system is an intelligent automatic control system, which is mainly installed on the distance sensor or radar at the front of the vehicle to detect whether there is a slower vehicle on the road ahead of the vehicle while the vehicle is driving. If there is a slower vehicle, the adaptive cruise control system will reduce the speed of the vehicle and control the gap between the vehicle and the vehicle in front to reach the preset target distance, so that the vehicle and the vehicle in front are in a stable state to avoid vehicle collisions. Drive at a predetermined distance from the vehicle in front. [0003] In order to keep the self-vehicle and the vehicle in front in a stable state, the adaptive cruise system needs...
