  • Patent number: 4949820
    Abstract: A vehicle creep control system which has: a speed transducer arrangement coupled to the vehicle's speedometer cable or the like, which provides an active output whenever the vehicle stops; an accelerator switch connected to the accelerator pedal, which has an active output whenever the driver's foot depresses the accelerator pedal; a latching circuit with a set input connected to the speed transducer arrangement and a clear input connected to the accelerator switch; a first delay circuit connected to the output of the latching circuit, such that when the latching circuit is set due to the vehicle slowing down to the given low speed value, a first set signal is connected to the delay circuit, which in turn produces a delayed output, after a given first delay time, so that the brakes are actuated and hold the vehicle.
