Problems solved by technology

However, when the existing adaptive cruise control system controls the vehicle to pass through the curve, if there is no target vehicle in front and the set speed is too high, it will easily lead to excessive lateral acceleration of the vehicle when cornering, affecting comfort, and may even Loss of vehicle control due to lack of grip
Conversely, if the vehicle slows down too early before entering the curve, or passes through the curve at a lower constant speed, it will affect the traffic smoothness and driving experience

Abstract

The invention discloses a vehicle turning speed determining method and device, an electronic device and a vehicle. The method includes the steps of obtaining curve information of a road in front of the vehicle and the adaptive cruise limiting speed of the vehicle, wherein the curve information includes position information of characteristic points on a corresponding curve and the curve curvature;determining the corresponding preset turning speed when the vehicle passes through all characteristic points on the curve based on the position information of the characteristic point and the curve curvature; obtaining a preview distance of the vehicle within the preview time based on the current speed of the vehicle; obtaining the minimum preset cornering speed of corresponding curve parts withinthe preview distance from the current position of the vehicle; if the minimum preset turning speed is less than the adaptive cruise limiting speed, according to the current speed of the vehicle and the preset turning speed of all the characteristic points within the preview distance, determining the target turning speed when the vehicle passes through all the characteristic points on the curve. The method can reasonably determine and control the turning speed of the vehicle and improves the driving safety and the driving experience.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a method, device, electronic equipment and vehicle for determining the cornering speed of a vehicle. Background technique [0002] With the advancement of vehicle control technology, the adaptive cruise control system has received extensive attention, which can control the driving state of the vehicle according to the road conditions and reduce the burden on the driver. However, when the existing adaptive cruise control system controls the vehicle to pass through the curve, if there is no target vehicle in front and the set speed is too high, it will easily lead to excessive lateral acceleration of the vehicle when cornering, affecting comfort, and may even Loss of vehicle control due to lack of grip. On the contrary, if the vehicle slows down too early before entering the curve, or passes through the curve at a lower constant speed, it will affect the smooth traffic and...
