The present disclosure relates to an auxiliary braking system comprising a man-machine interface device that generates an auxiliary braking request signal when in a working position and stops generating the auxiliary braking request signal when in a neutral position, and a control device, the man-machine interface device being capable of being placed in at least two working modes, in a first working mode, in which the man-machine interface device generates an auxiliary braking request signal when in a neutral position, and in a second working mode, in which the man-machine interface device stops generating the auxiliary braking request signal. In the first working mode, the man-machine interface device cannot be switched from the working position to the neutral position without external force, and in the second working mode, the man-machine interface device can be automatically reset from the working position to the neutral position without external force; the control device causes the engine to enter the in-cylinder brake mode when the auxiliary brake request signal is received, and causes the engine to leave the in-cylinder brake mode when the auxiliary brake request signal is not received. By means of the auxiliary braking system, auxiliary braking of the engine can be achieved in different working modes so as to meet different braking requirements of a driver, and the operation convenience of the driver is improved.

    本公开涉及一种辅助制动系统,包括人机接口装置和控制装置,人机接口装置在处于工作位置时产生辅助制动请求信号,并且在处于中性位置时停止产生辅助制动请求信号,人机接口装置能够被置于至少两种工作模式,在第一工作模式下,在不受外力作用时,人机接口装置不能从工作位置切换至中性位置,在第二工作模式下,在不受外力作用时,人机接口装置能够从工作位置自动复位至中性位置;控制装置在接收到辅助制动请求信号时使得发动机进入缸内制动模式,并且在不能接收到辅助制动请求信号时使得发动机离开缸内制动模式。利用本公开的辅助制动系统,能够以不同的工作模式来实现发动机辅助制动以满足驾驶员的不同的制动需求,提升了驾驶员的操作便捷性。
