Title:
CONTROL METHOD FOR ELECTRONIC THROTTLE VALVE DEVICE
Document Type and Number:
Japanese Patent JP3798244
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve the problem of causing knockings, when opening a throttle valve by matching with a stepping quantity of an accelerator pedal at starting time or accelerating time of a vehicle, in an electronic throttle valve device.
SOLUTION: In this control method for controlling the driving of the throttle valve 1, so that the opening change rate of the throttle valve 1 becomes slower than a change in an accelerator pedal operation quantity at starting time or accelerating time of the vehicle by opening and closing the throttle valve 1 on the basis of the detected accelerator pedal operation quantity, by detecting the accelerator pedal operation quantity of the vehicle mounted with an internal- combustion engine having the throttle valve 1, the throttle valve 1 is controlled, so that the opening change rate becomes slower than the opening change rate, when suction air temperature is low, as the detected suction air temperature becomes gradually high, by detecting the suction air temperature of the internal- combustion engine.
