Title:

THROTTLE CONTROL DEVICE

Document Type and Number:

Japanese Patent JP3314540

Kind Code:

B2

Abstract:

PURPOSE: To reduce the load of accelerator operation and smoothly start a vehicle on a slope or a snow-covered road by determining the threshold value of the driving wheel revolving speed acceleration based on the accelerator pedal action quantity and the shift position, and controlling a throttle actuator in response to its difference with the present driving wheel revolving speed acceleration.
CONSTITUTION: This throttle control device is provided with an accelerator sensor l detecting the accelerator pedal action quantity and a shift position sensor 3 detecting the shift position of a shift lever, and their output signals are inputted to a controller 4. The controller 4 determines the threshold value based on the present accelerator pedal action quantity and the shift position. When the present driving wheel revolving speed acceleration is larger than the threshold value, the controller 4 controls an actuator 5 in response to the difference. The controller 4 sets the recovery time of a throttle 7 based on the accelerator pedal action quantity and the difference, and it gradually returns the throttle opening gain to the original value during the recovery time when the present driving wheel revolving speed acceleration is smaller than the threshold value.
