  • One pedal safety driving system
    Patent number: 5810107
    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).
