The invention discloses a combined braking control method for a whole vehicle. The combined braking control method comprises the following steps: S1, collecting an opening signal of a brake pedal; SS1, comparing the opening degree of the brake pedal with a calibrated opening degree threshold value of the brake pedal, and if the opening degree of the brake pedal is greater than or equal to the calibrated opening degree threshold value of the brake pedal, executing S4; otherwise, executing the S5; and S3, sending a braking request to the retarder, requesting the retarder braking torque ratio obtained in the S2. The device conducts combined braking based on the opening degree of a braking pedal, the braking torque ratio of the retarder is automatically adjusted according to the opening degree of the braking pedal, and the braking and exhaust braking functions in an engine cylinder are automatically started and stopped. And the driving brake linkage with each auxiliary brake function can be completed only through the brake pedal, so that the operation is simple, the brake functions on the whole vehicle are integrated together, and unified management and control are realized.

    本发明公开了一种整车联合制动控制方法,其步骤如下:步骤S1,收集制动踏板开度信号;步骤SS1将制动踏板开度与标定的制动踏板开度阈值比较,如果制动踏板开度大于等于标定的制动踏板开度阈值,那么执行步骤S4;否则执行步骤S5;步骤S3,向缓速器发送制动请求,请求步骤S2中得到的缓速器制动扭矩比,此装置基于制动踏板开度进行联合制动,根据制动踏板开度,自动调节缓速器制动扭矩比,自动启动关闭发动机缸内制动、排气制动功能。仅通过制动踏板即可完成行车制动联动各个辅助制动功能,这样操作简单,将这整车上的各制动功能集中在一起,实现统一管理与控制。
