Abstract

The invention relates to the technical field of vehicle control, and provides a vehicle flameout sliding control method and device. The method comprises the steps that the running state of the vehicle and the state of a brake pedal are judged; detecting the vacuum degree of a vacuum booster of the vehicle when it is judged that the running state of the vehicle is flameout sliding and the state of the brake pedal is stepping down; and when it is detected that the vacuum degree is smaller than or equal to the first preset vacuum degree and the vehicle meets the active pressurization condition, a motor of the vehicle is controlled to be pressurized. According to the method, it can be guaranteed that the vehicle can reach the expected deceleration, and therefore safety is guaranteed.

本发明涉及车辆控制技术领域，提供一种车辆熄火滑行的控制方法和装置。本发明所述的方法包括：判断所述车辆的行驶状态和制动踏板的状态；在判断到所述车辆的行驶状态为熄火滑行且所述制动踏板的状态为踩下时，检测所述车辆的真空助力器的真空度；在检测到所述真空度小于或等于第一预设真空度，且所述车辆满足主动增压条件时，控制所述车辆的马达电机增压。该方法可以保证车辆能够达到预期的减速度，从而确保安全。
