A double-pedal braking device of a vehicle comprises an air cylinder, a front axle booster pump, a rear axle booster pump, a front axle brake, a rear axle brake, a right foot brake valve, a left footbrake valve, a shuttle valve, a double-acting cut-off air cylinder, a first electromagnetic valve, a main controller and a gradient sensor. An execution port A of the left foot brake valve is communicated with an air inlet P of the first electromagnetic valve, and an execution port A of the first electromagnetic valve is communicated with a rodless cavity of the double-acting cut-off cylinder; andthe wiring end K of the first electromagnetic valve and the gradient sensor are both in electric connection or wireless communication connection with the main controller. Even if the brake valve is mistakenly stepped on a downhill road section, a power cut-off function cannot be achieved.

    一种车辆的双踏板制动装置,包括储气筒、前桥加力泵、后桥加力泵、前桥制动器、后桥制动器、右脚制动阀、左脚制动阀、梭阀、双作用切断汽缸、第一电磁阀、主控制器和坡度传感器;所述左脚制动阀的执行口A与第一电磁阀的进气口P连通,第一电磁阀的执行口A与双作用切断汽缸的无杆腔连通;所述第一电磁阀的接线端K和坡度传感器均与主控制器电连接或无线通讯连接。本发明能实现即使在下坡的路段发生踩错制动阀的情况,也不会带有动力切断功能。
