Abstract: A control device for a braking system of a vehicle including a stationary ferromagnetic plate, a lever pivotally mounted on the plate and operationally connected to a brake pedal to rotate in accordance with the movement of the brake pedal, an electromagnet mounted on the lever and electrical control circuit for the electromagnet whereby when energized the electromagnet is fixed on the plate by attractive force so that the brake pedal is retained at the position. An electric coil of the electromagnet is connected in series to a circuit including in parallel a first switch associated to an accelerator pedal and a second switch associated to a clutch pedal so that the electromagnet is deenergized when both accelerator pedal and clutch pedal are actuated, thereby releasing the brake.

Abstract: A braking control apparatus for a vehicle which locks and holds the brake pedal of the vehicle in a given depressed position. The apparatus is rendered inoperative when the vehicle is in such a condition that the locking and holding of the brake pedal is undesirable. When starting the vehicle, an accelerator pedal switch operatively connected to the accelerator pedal deenergizes an electromagnet for locking the brake pedal. With the brake pedal locked in any given depressed position, any further depression of the brake pedal results in deenergization of the electromagnet by the brake pedal switch operatively connected to the brake pedal. With the vehicle at rest, when the door is opened, the electromagnet is deenergized by a door switch. Also, during rapid braking of the vehicle, another brake pedal switch which is operatively connected to the brake pedal actuates a latching relay to deenergize the braking control apparatus.
