ABSTRACT:
Foot operated safety driving system, that realizes slow down of vehicle by driver's pushing a gas pedal (10). A foot toe pressure piezoelectric sensor (12T) and a foot heel sensor (12H), joined with gas pedal (10), convert all driver's foot pressure impulses to an electric signal; a sensors' cord (78) transmits the signal to an electric device (74). An input processing circuit of the device (74) selects from the electric signal a brake pulse by comparators (28) and (30), verifies and forms the brake pulse by a strobing transistor (22) and a conjunction gate (32), and uses the processed brake pulse to actuate a group of output thyristor controllable electron valves (34), (36), (38). Output current of thyristor (34) by an output cord (84) actuates a 3-way brake fluid distributor valve (56) and a 2-way fuel bypass valve (58), placed in a basic executive set (60), whereby the system switches vehicle's regime from accelerating to braking by converting its kinetic energy to friction energy; after preventing an accident the driver switches the vehicle regime back from braking to accelerating by operating interruption output current pushbuttons (40), (42), (44).
