Title:
DRIVING POWER CONTROL METHOD FOR VEHICLE
Document Type and Number:
Japanese Patent JPH0195946
Kind Code:
A
Abstract:
PURPOSE:To improve the controllability of a car speed decreasing a change amount of driving power by correcting the driving power of a drive wheel, corresponding to a step-in amount of an accelerator pedal, to a direction of less power in accordance with a condition of obstacle existing in the advancing direction of a vehicle. CONSTITUTION:An engine 10 is controlled by a linkless throttle valve 18 provided in an intake pipe 16. While an automatic transmission 12 is controlled by many solenoid valves S1-S3. The valve 18 and each solenoid valve S1-S3 are driven by a signal output from a control circuit 20, respectively. While the control circuit 20 inputs each signal from an engine speed sensor 22, car speed sensor 26, shift position sensor 30, accelerator pedal step-in amount sensor 34 and each front and rear obstacle sensor 36, 38. Here in accordance with a condition of obstacle existing in the advancing direction of a vehicle, driving power of a drive wheel corresponding to a step-in amount of an accelerator pedal 32 is corrected to a direction of less power.
