Abstract
A cruise control sub-system is incorporated into an electronic throttle control system. The sub-system comprises a cruise control module that provides respective charge and discharge signals to a circuit for charging and discharging a capacitor. The voltage across the capacitor represents a cruise control signal and is supplied to a port of the electronic throttle control microprocessor. In the cruise control mode of operation, the microprocessor causes the throttle to be positioned by the cruise control signal. If the driver depresses the accelerator pedal to an extent that would command a throttle opening larger than that commanded by the cruise control signal, the microprocessor causes to throttle to be operated to the larger opening. When the cruise control mode of operation ceases, the throttle is controlled by the accelerator pedal alone. The microprocessor also performs testing of the cruise control sub-system and gives a fault indication if a fault is detected.
