Automotive speed control device

A speed control device for an automotive vehicle having an accelerator member selectively movable by a vehicle operator between an accelerating position and a decelerating position, comprising in combination:

• speed responsive means having a fluid pressure converter responsive to a vehicle speed to produce an operating fluid pressure when the vehicle speed exceeds a predetermined level;
• pressure responsive means operatively connected between the speed responsive means and the accelerator member and responsive to the operating fluid pressure to apply a force of the operating fluid pressure to the acceleration member to hold the same at the decelerating position providing a speed lower than the predetermined level;
• relief means operatively connected to the accelerator member to relieve a force applied to the accelerator member by the vehicle operator against the force of the operation fluid pressure applied to the same;
• release signal producing means cooperated with an alarm provided in the vehicle to produce a release signal when the alarm is actuated;
• and,
• pressure release means provided between the speed responsive means and the pressure responsive means and responsive to the release signal to release the operating fluid pressure whereby the accelerator member is movable to the accelerating position.
