The invention provides a vehicle braking control method and device and a vehicle, and the method comprises the steps: carrying out the clustering according to a first sample point, and obtaining a target driving style; obtaining a current road condition parameter group and a plurality of Markov chains, and calculating a road condition corresponding to the first moment according to the current road condition parameter group and the plurality of Markov chains to obtain a first target road condition; the first mapping relation is inquired according to the target driving style and the first target road condition to obtain target braking torque, a corresponding braking mode is activated according to the target braking torque, and the braking mode at least comprises one of exhaust butterfly valve braking, first-stage in-cylinder braking and second-stage in-cylinder braking. According to the method, the problem that in the prior art, a corresponding braking mode cannot be flexibly activated according to the driving habit of a driver and the current road condition to provide suitable braking torque for the vehicle, and consequently driving comfort is poor is solved.

    本申请提供了一种车辆的制动控制方法、制动控制装置和车辆,该方法包括:根据第一样本点进行聚类,得到目标驾驶风格;获取当前路况参数组和多个马尔可夫链,并根据当前路况参数组和多个马尔可夫链计算第一时刻对应的路况得到第一目标路况;根据目标驾驶风格和第一目标路况查询第一映射关系得到目标制动扭矩,并根据目标制动扭矩激活对应制动方式,制动方式至少包括以下之一:排气蝶阀制动、一级缸内制动和二级缸内制动。该方法解决了现有技术中的制动方式不能根据驾驶员的驾驶习惯和当前路况灵活激活对应的制动方式为车辆提供适合的制动扭矩,导致驾驶舒适性较差的问题。
