Abstract
A braking system for an automobile responsive to the abrupt release of an accelerator pedal. The system includes a solenoid for actuating the braking apparatus, a first switch adapted to be closed in response to a depression of the accelerator pedal, so as to prepare for the energization of the solenoid, and a second switch adapted to be closed in response to an abrupt release of the accelerator pedal to allow the energization of the solenoid to bring the braking apparatus into effect. The first switch is opened when the accelerator pedal has returned to the original position, so as to de-energize the solenoid and suspend the operation of the braking apparatus. The braking apparatus is brought into effect again by a subsequent depression of the brake pedal. The braking system incorporates a brake force doubling mechanism for allowing the functioning of both of the solenoid-actuated operation and human-actuated operation, so arranged as to provide for the functioning of the braking apparatus by the solenoid in response to the driver's intent to stop the automibile and, then, the functioning of the braking apparatus in response to the depression of the brake pedal.
