Driving power control apparatus for vehicle

Abstract

Disclosed is a driving power control apparatus for a vehicle driven by an engine. A throttle valve which is openable and closable by a DC motor is provided in an air intake passage of the engine. The vehicle is provided with an acceleration sensor and a vehicle speed sensor. The vehicle is further provided with an accelerator pedal sensor for detecting the manipulation amount of the accelerator pedal that is manipulated by a driver. The vehicle is also provided with a neuro computer and a throttle computer for controlling the angle of the throttle valve based on the result of the detection by various sensors. With the acceleration detected by the acceleration sensor used as teaching data to be compared, the neuro computer learns the relationship among the manipulation amount detected by the accelerator pedal sensor, the speed detected by the vehicle speed sensor and the acceleration, as the output of a 'requested-acceleration model'. The neuro computer computes a throttle sensitivity from the difference between the output of the 'requested-acceleration model' and the output of a standard 'reference acceleration model' previously learned. Based on the throttle sensitivity output from the neuro computer, the throttle computer controls the DC motor in accordance with the manipulation of the accelerator pedal. Accordingly, the angle of the throttle valve is controlled and the output of the engine is controlled, thus controlling the driving power of the vehicle.
