Claims

[Scope of utility model registration request]

A brake valve that changes the stroke of a plunger according to the amount of depression of the brake pedal to control the increase or decrease of the braking force by the service brake, a piston that contacts the plunger from the return direction of the plunger, and the piston. A parking brake that detects the position of a parking brake lever in an automobile brake lock device that includes a normally closed manual valve that connects a chamber and an air tank, and a return spring that slides and biases the piston in the return direction of the plunger. a switch, an operation force sensor that detects the operation force of the parking brake,
The parking brake lever is operated to the operating position via the parking brake switch and the operating force sensor,
Only when it is detected that the operating force applied to the parking brake is equal to or higher than a predetermined value, the manual valve is allowed to open, and at the same time, a ready notification means is activated to notify the driver that the operation preparation is completed. a control relay that detects the operation state of the manual valve, a pressure switch that detects the pressure of the working fluid supplied to the service brake, and a control relay that detects the operating state of the manual valve. A lock confirmation notification means is provided that notifies the driver that the brake is securely locked only when the service brake is operated to the operating position and the pressure of the working fluid supplied to the service brake is detected to be above a predetermined value. A confirmation relay to be activated and a warning means to be activated when a decrease in pressure of the working fluid occurs while the manual valve is being operated are provided, and the control relay and the confirmation relay are housed in the same relay box. An automobile brake lock device characterized by:
