Abstract
An electronic control unit adjusts drive force generated by an engine in accordance with the amount of manipulation of an accelerator pedal. When the manipulation amount of the accelerator pedal meets a predetermined condition, the electronic control unit executes drive force limiting control for limiting the drive force generated by the engine and changes the degree of limiting of the drive force during the execution of the drive force limiting process according the gradient of the road surface.
Claims4
A drive force control device for a vehicle having a drive source, the drive force control device comprising:
- an accelerator;
- an accelerator manipulation amount sensor configured to detect a manipulation amount of the accelerator;
- and
- an electronic control unit, wherein the electronic control unit is configured to:
- adjust a drive force generated by the drive source in accordance with the accelerator manipulation amount,
- set a target acceleration of the vehicle based on a vehicle speed, when one of the accelerator manipulation amount, a rate of change of the accelerator manipulation amount, or an acceleration of change of the accelerator manipulation amount, is greater than or equal to a predetermined value,
- when a vehicle acceleration is greater than or equal to the target acceleration, execute a drive force limiting process, to limit the drive force generated by the drive source to a value lower than a value that corresponds to the acceleration manipulation amount and
- during execution of the drive force limiting process, reduce the degree of limiting of drive force as the gradient of a road surface of an uphill increases.
