The invention relates to a vehicle brake control method and device and a vehicle, and aims to solve the problem of low vehicle brake control accuracy. The method comprises the steps: in response to anobtained braking request, determining braking information that a vehicle slides to be stopped under the non-input working condition according to the current running speed of the vehicle; determiningwhether the braking information meets a preset braking condition or not; if not, adjusting the driving speed; when the brake information of the adjusted running speed meets the brake information corresponding to the preset brake condition, determining a first brake pedal opening degree according to the adjusted running speed and a preset sliding speed threshold value, and controlling the vehicle to brake at the first brake pedal opening degree; and when the vehicle is braked at the first brake pedal opening degree until the running speed is smaller than or equal to the preset sliding speed threshold value, controlling the vehicle to slide under the non-input working condition. Therefore,, the accuracy of vehicle brake control can be improved.
本公开涉及一种车辆制动控制方法及装置,车辆,以解决车辆制动控制精确度较低的问题。包括:响应于所获取到的制动请求,根据车辆当前行驶速度确定车辆在无输入工况滑行至停车的制动信息;确定制动信息是否满足预设制动条件;在制动信息不满足预设制动条件时,调整行驶速度;在调整后行驶速度的制动信息满足预设制动条件相应的制动信息时,根据调整后行驶速度和预设滑行速度阈值,确定第一制动踏板开度,控制车辆以第一制动踏板开度进行刹车;在车辆以第一制动踏板开度刹车到行驶速度小于等于预设滑行速度阈值时,控制车辆以无输入工况滑行。这样,可以提高车辆制动控制的精确度。
