Abstract

The invention discloses a method and a device for controlling vehicle running, belonging to the technical field of vehicle electrical control. The method includes: determining the distance between the vehicle and any lane line of the current lane based on the lane image obtained by shooting the current lane with the camera of the vehicle; when the distance between the vehicle and any lane line of the current lane is When the distance is less than the preset threshold, it is determined that the vehicle deviates from the current lane; the current deviation angle of the vehicle from the current lane is obtained; according to the current deviation angle, the reverse steering torque corresponding to the current deviation angle is determined; the steering wheel is controlled by the Reverse steering torque is turned to deflect the vehicle back into the current lane. The ECU can automatically identify whether the vehicle deviates from the current lane, and control the vehicle to return to the current lane again, thereby improving the safety of driving the vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicle electrical control, in particular to a method and device for controlling vehicle running. Background technique [0002] In the process of driving, safe driving is related to the personal safety of the driver and other people around. According to statistics, there are countless traffic accidents caused by the driver's failure to drive safely every year. In order to ensure safe driving and avoid traffic accidents, the driver needs to concentrate, pay attention to the surrounding environment and vehicle status at all times, and control the vehicle to drive safely according to the surrounding environment and vehicle status. [0003] However, after a long time of safe driving, the driver is prone to driving fatigue and cannot concentrate all the time. Traffic accidents such as collisions with other vehicles on the lane, or even rollovers. Therefore, in order to solve the phenomenon that the vehicle d...
