A parking braking and flameout linkage control device for a vehicle comprises an air pocket, a starting electromagnetic valve, a pneumatic control hydraulic reversing valve, a parking brake, a manualreversing valve, an energy accumulator, a storage battery, a power main switch, a generator, a key switch, an engine ECU, a controller, a first relay, a pressure switch and a fourth relay. An execution port A of the manual reversing valve is communicated with a hydraulic control port A of the pressure switch; the other end of the first contact switch of the first relay is electrically connected with one end of a wiring end K of the pressure switch, and the other end of the wiring end K of the pressure switch is electrically connected with a binding post B of the engine ECU; a wiring end N of the generator is electrically connected with one end of a fourth coil of the fourth relay, and the other end of the fourth contact switch is electrically connected with one end of a wiring end K of thestarting electromagnetic valve 3. When the parameters exceed the standard, the engine is automatically shut down, parking braking is automatically conducted, and parking braking cannot be automatically relieved after a vehicle is started and when the parameters are normal.
一种车辆的停车制动和熄火联动控制装置,包括气包、启动电磁阀、气控液压换向阀、停车制动器、手动换向阀、蓄能器、蓄电池、电源总开关、发电机、钥匙开关、发动机ECU、控制器、第一继电器、压力开关和第四继电器;手动换向阀的执行口A与压力开关的液控口A连通;第一继电器的第一触点开关的另一端与压力开关的接线端K的一端电连接,压力开关的接线端K的另一端与发动机ECU的接线柱B电连接;发电机的接线端N与第四继电器的第四线圈的一端电连接,第四触点开关的另一端与启动电磁阀3的接线端K的一端电连接。本发明可实现参数超标时,使发动机自动熄火并自动进行停车制动,车辆启动后且参数正常时停车制动不会自动解除。
