徴とする車両用ロツクブレーキ装置。 In a vehicle, a brake tank that stores a pressure-adjusted working fluid; a hydraulic pressure conversion device that receives working fluid pressure from the brake tank via an operating system piping with an on-off valve and converts it into brake hydraulic pressure;
A brake wheel cylinder that operates in response to the converted hydraulic pressure from the hydraulic pressure conversion device, a control system piping that sends a working fluid pressure signal from the brake tank to the on-off valve, and a control system piping that is inserted into the control system piping. A parking brake sensor for detecting an operating state or a released state of a parking brake, comprising a manual valve for operating a lock brake, and a lock mechanism capable of maintaining the manual valve in a released state. and a solenoid capable of unlocking the locking mechanism upon receiving an operation detection signal from the parking brake sensor;
A valve stroke switch capable of detecting the operating state of the manual valve, and an alarm that sounds when the excitation coil is energized, an operation detection signal is sent from the parking brake sensor, and the stroke of the manual valve is detected. When the valve stroke switch is turned on, the excitation coil is de-energized, an operation detection signal is sent from the parking brake sensor, and after the valve stroke switch is turned on, the parking brake sensor releases the current. When a detection signal is sent out, the excitation coil is energized, and after an operation detection signal is sent out from the parking brake sensor and the valve stroke switch is turned on, when the valve stroke switch is turned off, the excitation coil is turned off. A lock brake device for a vehicle, characterized by comprising a transistor circuit that de-energizes a coil.
