Claims

[Claims for Utility Model Registration] (1) An accelerator switch, a clutch switch, a neutral switch, a braking electromagnetic check valve, and at least the clutch switch and the neutral switch when the vehicle is in a starting state. A braking force holding device comprising: a control means for deenergizing a check valve. (2) The control means is configured such that the accelerator switch is on when the accelerator pedal is released, the clutch switch is on when the clutch pedal is depressed, or the neutral switch is on when the gear is in neutral. The foot brake switch, which is turned on when the foot brake is depressed, is on.
A utility model that energizes the check valve to generate braking force when a braking permissible state continues for a certain period of time or more, indicating that the output of the vehicle speed sensor is below a predetermined speed and below a predetermined deceleration. A braking force holding device according to registered claim 1. (3) The control means is configured to control the check valve when the accelerator switch is turned off, when the clutch switch and the neutral switch are both turned off, and when this vehicle starting state continues for a certain period of time or more. A braking force holding device according to claim 1 or 2 of the utility model registration claim. (4) The braking force holding device according to claim 1, wherein the vehicle starting state includes a parking brake operating state.
