Accelerator pedal reaction force control device
First Claim
1. An accelerator pedal reaction force control device that is mounted on a motor vehicle provided with a cylinder deactivation engine and controls a depression reaction force of an accelerator pedal for adjusting an output of the cylinder deactivation engine, wherein the cylinder deactivation engine is provided with a depression amount detection means that detects an amount of depression of the accelerator pedal such that cylinder reactivation control for increasing a number of active cylinders is performed when an operation state quantity including the amount of depression of the accelerator pedal becomes larger than a cylinder reactivation threshold value, and cylinder deactivation control for reducing the number of active cylinders is performed when the operation state quantity becomes smaller than a cylinder deactivation threshold value, the accelerator pedal reaction force control device comprising:
- a reaction force providing device that provides the accelerator pedal with a depression reaction force; and
a target depression reaction force setting device that sets a target depression reaction force for the reaction force providing device,wherein, in a case where the cylinder deactivation engine is in a cylinder deactivation operation state in which some of the cylinders are inactive, the target depression reaction force setting device calculates a requested output for the cylinder deactivation engine based on the operation state quantity including the amount of depression of the accelerator pedal, estimates a maximum output that can be produced by the cylinder deactivation engine in the cylinder deactivation operation state, calculates a difference between the maximum output and the requested output as an output difference, and then, increases the target depression reaction force in accordance with the output difference.

Abstract
A reaction force control unit calculates a driver'"'"'s requested output and then estimates a maximum output that can be generated by an engine in a current cylinder deactivation operation. Next, the reaction force control unit calculates a difference between the maximum output and the requested output as an output difference and then determines whether the output difference has reached a predetermined reaction force start threshold value, and if the determination result is Yes, the reaction force control unit estimates a number of to-be-reactivated cylinders on the basis of the output difference and the current cylinder deactivation operation state. Subsequently, the reaction force control unit sets a target reaction force on the basis of the output difference and the number of to-be-reactivated cylinders, and outputs drive current to a reaction force actuator.
