Control method, device, electronic device and storage medium for stable driving of vehicle

Abstract

The present application relates to a control method, device, electronic device, and storage medium for stable driving of a vehicle. The method includes: if it is determined that there is an obstacle in the current driving path, based on the acquired size of the obstacle and the current speed of the vehicle, from the current driving path Determine the path to be adjusted; determine the quasi-target torque value based on the size of the obstacle; when the vehicle enters the path to be adjusted, convert the current torque change rate controlled by the on-board system into the target torque change rate; The steering wheel torque value and the quasi-target torque value input by the driver determine the target torque value; send the target torque value and the target torque change rate to the steering system of the vehicle. In the present application, by increasing the current torque change rate, the response speed of the vehicle to road obstacles can be improved, and the excessive lateral offset caused by the influence of road obstacles can be reduced. In this way, the driving of the vehicle in the automatic driving mode can be improved. Stability and improved driving comfort.

Description

technical field [0001] The present application relates to the technical field of automobiles, and in particular, to a control method, device, electronic device and storage medium for stable driving of a vehicle. Background technique [0002] With the popularization of automobiles and the development of automatic driving technology, people have higher and higher requirements for the stability and safety of the automatic driving system of automobiles, and the development and application of automobile active safety functions have also risen to a new stage accordingly. At present, the realization of the active safety function of each automatic driving system is basically based on the detection and recognition capabilities of the front millimeter-wave radar, front camera, and car corner radar to detect and identify the road condition information around the vehicle, and to make the most correct choice. Realize the control of the vehicle. [0003] For example, Traffic Jam Polot (T...

Problems solved by technology

[0004] But in reality, the road conditions are more complex, such as potholes, uneven roads, branches and other small obstacles that cannot be avoided but can be crossed

If TJP does not do special handling for these situations, when passing through these road conditions, it will cause the vehicle to shake a lot in lateral control, which may endanger the safety of the driver on the one hand; on the other hand, it may cause the vehicle to deviate from its own lane, resulting in TJP accidents exit, which increases driver tension and reduces driver comfort
