A control method and control system for starting a vehicle

Abstract

The invention provides a vehicle starting control method and a control system, and belongs to the field of vehicles. The control method comprises the following steps: collecting running state information of a vehicle; sending the running state information to a brake controller of the vehicle when the vehicle is in an automatic driving mode and the vehicle speed is smaller than a preset speed threshold value; enabling the brake controller to calculate a target acceleration according to the running state information; and controlling the vehicle to run according to the target acceleration. The invention further provides the control system for executing the control method. According to the control method and the control system, the problems of high cost and poor real-time performance caused bythe fact that the vehicle overcomes acceleration fluctuation in a low-speed stage can be solved.

Description

technical field

[0001] The invention relates to the field of vehicles, in particular to a control method and a control system for starting a vehicle. Background technique

[0002] At present, vehicles are becoming more and more intelligent, and intelligent functions emerge in an endless stream, such as adaptive cruise control, traffic congestion assistance, and automatic driving. The acceleration and deceleration of these functions are completely dependent on the acceleration and deceleration requests sent by the radar. When the self-vehicle starts following the vehicle in front, from a complete stop to a certain low speed (about 7kph), the distance between the self-vehicle and the vehicle in front detected by the radar fluctuates up and down in a wave shape, causing the acceleration to fluctuate up and down, showing a The wavy shape makes the acceleration process at this stage uneven and seriously affects the driving experience.

[0003] In order to solve the problem that...
