Abstract

本申请公开了一种车辆控制方法及装置,涉及车辆控制技术领域。方法包括:获取车辆行进数据;获取车辆行进数据,车辆行进数据中包括制动信号数据;判断制动信号数据是否大于预设阈值;在制动信号数据大于预设阈值的情况下,按预设制动力斜率,对车辆施加制动力;预设制动力斜率低于请求制动力斜率。与相关技术相比,本申请通过按预设制动力斜率取代常规状态下根据车况计算得到的请求制动力斜率,从而使制动力增幅趋于平缓,以便于后续不会出现因制动力太高而降不下来导致滑移率过高且抖动,车辆严重失稳的问题,从而提高了ABS模块的控制稳定性。

The application discloses a vehicle control method and device, and relates to the technical field of vehicle control. The method comprises the steps of obtaining vehicle running data, obtaining the vehicle running data, wherein the vehicle running data comprises braking signal data, judging whether the braking signal data is larger than a preset threshold value, applying braking force to the vehicle according to a preset braking force slope when the braking signal data is larger than the preset threshold value, and enabling the preset braking force slope to be lower than a request braking force slope. Compared with the prior art, the application replaces the slope of the request braking force calculated according to the vehicle condition in the conventional state according to the preset braking force slope, so that the braking force amplification is gradually flattened, the problems of excessively high slip rate and shaking caused by excessively high braking force and incapability of reducing the braking force are solved, and the control stability of the ABS module is improved.
