  • Throttle control and failure accommodation
    Patent number: 6932743
    Abstract: One embodiment of the present invention is an apparatus including an internal combustion engine for powering a ground travelling vehicle, a throttle control arrangement including a device for sensing position of an operator-adjustable pedal to provide a throttle control signal, a first sensor to sense rotational speed of the engine, a second sensor to sense brake status of the vehicle, a way to determine failure of the throttle control signal, and a way to operate the engine in a limp-home mode in response to the failure, which includes fueling the engine during the limp-home mode of operation in accordance with idle position of the pedal, rotational speed of the engine, and the brake status.
