Abstract
In an accelerator pedal effort control apparatus which increases a pedal effort of an accelerator pedal 2 when an accelerator opening angle is larger than a predetermined accelerator opening angle threshold value, in a case where a steering angle of a steering wheel when a vehicle driver starts to increase an opening angle of accelerator pedal 2 is small, a pedal effort increment is a reference pedal effort increment (ΔF) and, in a case where the steering angle is large, is a relatively small pedal effort increment (ΔF−β). Thus, when the vehicle turns right or left from a stopped state, pedal effort increment (ΔF−β) is set to relatively be small so that a smooth acceleration becomes possible.
Claims11
An accelerator pedal effort control apparatus for a vehicle, the accelerator pedal effort control apparatus comprising:
- an accelerator opening angle detecting section configured to detect an accelerator opening angle;
- and
- a pedal effort modification section configured to modify a pedal effort of an accelerator pedal,
- wherein the accelerator pedal effort control apparatus is configured such that, when the accelerator pedal opening angle becomes larger than a predetermined accelerator opening angle threshold value and a running resistance of the vehicle is in a first range, the pedal effort modification section increases the pedal effort of the accelerator pedal to be larger than a base pedal effort by a first predetermined pedal effort increment, and
- wherein the accelerator pedal effort control apparatus is configured such that, when the accelerator pedal opening angle becomes larger than the predetermined accelerator opening angle threshold value and the running resistance of the vehicle is in a second range that is higher than the first range, the pedal effort modification section increases the pedal effort of the accelerator pedal to be larger than the base pedal effort by a second predetermined pedal effort increment that is lower than the first predetermined pedal effort increment.
