The invention relates to a braking control method for a vehicle. The braking control method comprises the following steps that the adhesion coefficient of a road surface is obtained; when the adhesion coefficient is lower than an adhesion coefficient threshold value and the vehicle is braked, a hydraulic compensation braking mode is entered, and in the hydraulic compensation braking mode, recovery braking and hydraulic compensation braking jointly bear the braking function; the hydraulic compensation braking torque is calculated according to the obtained target braking torque and the actual recovery braking torque, the hydraulic compensation braking torque is applied to wheels of the vehicle through a wheel brake, and the hydraulic compensation braking mode comprises an initial stage, a middle stage and an end stage; the hydraulic compensation brake torque gradually increases from the initial phase to the intermediate phase and gradually decreases from the intermediate phase to the end phase. The invention also relates to a computer program product, a braking system and a vehicle. The problem that the braking capacity of a vehicle on a low-adhesion road surface is insufficient can be reliably solved, and the pause feeling in the braking process is avoided.
本发明涉及一种用于车辆的制动控制方法,包括以下步骤:获取路面的附着系数;当附着系数低于附着系数阈值并且对车辆制动时,进入液压补偿制动模式,在液压补偿制动模式中由回收制动和液压补偿制动共同承担制动功能;根据获取的目标制动扭矩和实际回收制动扭矩计算出液压补偿制动扭矩,液压补偿制动扭矩通过车轮制动器施加在车辆的车轮上,其中,液压补偿制动模式包括初始阶段、中间阶段和结束阶段,液压补偿制动扭矩从初始阶段至中间阶段逐渐增大并且从中间阶段至结束阶段逐渐减小。还涉及一种计算机程序产品、制动系统和车辆。能够可靠地解决车辆在低附着路面上的制动能力不足的问题并且避免在制动过程中出现顿挫感。
