An automatic throttle for a hydrostatic transmission having a forward pedal and a reverse pedal. Each pedal actuates a swash plate on a hydraulic pump for forward and reverse travel. A first bell crank and a second bell crank are connected to the forward pedal and the reverse pedal respectively. Each bell crank may pull a Bowden cable connected to an engine throttle to increase engine speed when either of the pedals is depressed.

A pedal system containing a right foot pedal, a left foot pedal and a motion inverter mechanism. The right foot pedal is moveable from a right foot pedal neutral position to a depressed acceleration position. The left foot pedal is moveable from a left foot pedal neutral position to a depressed braking position. The motion inverter mechanism operatively couples to the right and left foot pedals, for movement of the right foot pedal or the left foot pedal in an opposite direction to a raised position upon depression of the other of the right foot pedal or the left foot pedal. Also disclosed is a method of preventing concurrent depression of the gas and brake pedal. The pedal system disclosed can allow left foot braking and can also prevent concurrent depression of the gas and brake pedals, and hence, avoid stalling an automobile. The pedal system may also be installed with drive by wire type automobiles.

An improved motor vehicle speed and braking control system configured to maximize performance and response times for braking to a driver's instinctual physiological and psychological response to a perceived need to decelerate. The system provides a throttle pedal and brake pedal system configured to cause braking and an immediate change of engine power to idle once a user touches or causes activation of safety switches by a proximity or contact with them directly or with the brake pedal or a sliding of the throttle pedal depending on the configuration. Accidental acceleration during any attempt to brake is thereby eliminated by the system.
