The invention discloses a vehicle braking control method and system based on braking capacity, and the control method comprises the steps: obtaining the temperature of a brake disc, querying a temperature-braking capacity table according to the temperature of the brake disc, and determining the corresponding braking capacity; when the braking capacity is smaller than or equal to a preset first braking capacity threshold value, sending a braking capacity display request to the instrument; when the braking capacity is smaller than or equal to a preset second braking capacity threshold value, determining the torque reduction percentage of the engine according to the braking capacity; and sending the torque reduction request and the engine torque reduction percentage a to an engine controller, and obtaining torque reduction execution information returned by the engine controller. The safety braking force can be guaranteed, and the safety risk is reduced.

    本发明公开了一种基于制动能力的车辆制动控制方法及控制系统,该控制方法,包括:获取制动盘温度,并根据制动盘温度查询温度‑制动能力表,确定对应的制动能力;在制动能力小于或等于预设的第一制动能力阈值时,向仪表发送显示制动能力请求;在制动能力小于或等于预设的第二制动能力阈值时,根据制动能力确定发动机降扭百分比;向发动机控制器发送降扭请求和所述发动机降扭百分比,并获取发动机控制器返回的降扭执行信息。本发明能保证安全制动力,降低安全风险。
