Engine control system limiting engine output based on vehicle operating environments

摘要

The invention provides a system for controlling a vehicle engine according to a plurality of stored torque patterns for various vehicle operating environments, based upon the accelerator pedal position and the vehicle speed. A vehicle environment, detection unit evaluates the vehicle environment and a target drive shaft torque pattern is selected from the plurality of target drive shaft torque patterns stored in a torque pattern storage. A target drive shaft torque calculating unit determines a target drive shaft torque from the selected target drive shaft torque pattern, the detected accelerator pedal operating amount and the detected vehicle speed. Finally, an engine output calculator determines an engine output at which a vehicle drive shaft generates the target drive shaft torque, and outputs the determined engine output to an engine output control unit.
