AI Technical Summary

Technical Problem

In automatic parking assist systems, the hydraulic pressure operating range of the braking system is relatively small, resulting in poor linearity in brake pressure control, which affects the vehicle's stability and control performance.

Method used

By adjusting the initial idle speed based on factors such as slope, ambient temperature, and atmospheric pressure when APA control is activated, the target idle speed is determined to improve the idle speed level and ensure stable vehicle control under different environmental and road conditions.

Benefits of technology

The improved hydraulic pressure operating range of the braking system enables more linear braking control, enhances the stability of APA control and its adaptability to influencing factors, and improves the vehicle's starting ability and driving experience under different conditions.

Abstract

The application provides an idle speed determination method and device, electronic equipment and readable storage medium. The method comprises the following steps: determining an initial idle speed when the APA control is in an activated state, wherein the initial idle speed is greater than a warm-up idle speed of a vehicle; and correcting the initial idle speed based on an influencing factor to obtain a target idle speed, wherein the influencing factor comprises at least one of a slope value, an ambient temperature value and an atmospheric pressure value, the slope value is used to represent a slope value of a road currently traveled by the vehicle, the ambient temperature value is used to represent a temperature value of an environment currently traveled by the vehicle, and the atmospheric pressure value is used to represent an atmospheric pressure value of an altitude currently traveled by the vehicle. The application solves the problems that the oil pressure working interval of the brake system is small and the linearity of the brake system when performing brake pressure control is poor.
