Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0022] Embodiment of the electronic parking brake control system of the present invention:
[0023] Such as figure 1 As shown, the parking brake control system of this embodiment includes: electronic parking brake switch 35, electronic parking control ECU 33, emergency braking control solenoid valve 42, parking brake control solenoid valve 41, gas switching valve 50 , Gas one-way valve 51, automobile brake air chamber 6, automobile air storage cylinder 7, pressure sensor 8.
[0024] In this embodiment, the electronic parking brake control ECU 33 has ports a and b for receiving vehicle speed signals. The electronic parking brake control ECU 33 is connected to the negative pole of the power supply 32 through the wire 10, and connected to the negative pole of the ignition switch 31 through the wire 16. One end, the other end of the ignition switch is connected...

The invention relates to an electronic parking brake control system and an automobile using the same. The electronic parking brake control system comprises an emergency brake solenoid valve and a parking brake solenoid valve, wherein one end of the emergency brake solenoid valve is used for connecting with a negative pole of a power supply through a wire, the other end of the emergency brake solenoid valve is connected with an emergency brake control output end of an electronic parking brake control electronic control unit (ECU), an air inlet of the emergency brake solenoid valve is connected with an air storage device through a pipeline, an air outlet of the emergency brake solenoid valve is used for connecting with a main brake air chamber of an automobile brake air chamber through a pipeline and an air change-over valve, and a vent hole of the emergency brake solenoid valve is connected with the atmosphere; and one end of the parking brake solenoid valve is used for connecting with the negative pole of the power supply through the wire, the other end of the parking brake solenoid valve is connected with a parking brake control output end of the electronic parking brake control ECU, an air inlet of the parking brake solenoid valve is connected with the air storage device through a pipeline, an air outlet of the parking brake solenoid valve is used for connecting with the parking brake air chamber of the automobile brake air chamber through a pipeline, and a vent hole of the parking brake solenoid valve is connected with the atmosphere. The unreliable brake control problem of a parking brake system of an existing pneumatic brake automobile is solved.
Description
technical field [0001] The invention relates to an electronic parking brake control system and an automobile using the system. Background technique [0002] At present, most of the parking brake systems of cars using air brakes are mechanical parking brake control systems. The parking brake controller is arranged near the driver. When the driver needs to park, pull up the parking brake handle. The gas controlled by the brake chamber of the car is discharged into the atmosphere to realize the parking brake. The parking brake operation requires a lot of force, and frequent operations make the driver's labor intensity greater. If the driver uses less force, there is a risk that the brake will not be in place. If the driver forgets to pull up the parking brake when parking If the brake controller is not installed, the car cannot realize the parking brake, and there is a risk of the car rolling away by itself, which will cause a major accident of car crash and death in serious c...
