ABSTRACT:
In a throttle control system in which a controller monitors accelerator position and controls throttle valve position accordingly rather directly coupling the accelerator to the throttle valve, a sensor monitors vehicle driving conditions related to desired engine output response and the controller adjusts the relationship between throttle valve position and accelerator position in accordance with the detected vehicle driving conditions. Factors indicative of driving conditions monitored by the sensor may include wheel slippage and selection of reverse transmission gear, in which case the controller will reduce the stroke of the throttle valve when either excessive wheel slippage or reverse gear is detected. Each monitored factor may be associated with a distinct characteristic curve relating throttle valve position to accelerator position with the appropriate characteristics being selected by the controller in accordance with the detected vehicle driving conditions.
