Claims

[Claims for Utility Model Registration] An accelerator displacement amount detection means for detecting the displacement amount of an accelerator operator; An engine temperature that detects the engine temperature directly or indirectly through the temperature of a cooling liquid, etc. a detection means; an engine temperature range discrimination means for discriminating to which of a plurality of predetermined temperature ranges the detected engine temperature falls; an amount of displacement of an accelerator operator and an opening degree of a throttle valve; A plurality of sets of predetermined relationships with the target value are set, one of the sets is selected according to the discriminated temperature range, and the opening degree for the detected displacement amount is selected in the selected set. A control signal generating means for outputting a control signal indicating a target value; and a throttle valve driving means for driving the throttle valve to open and close so that the target opening value matches the actual throttle valve opening. Accelerator control device for vehicles.
