Abstract
For a pedal travel, a pedal reaction force, a driving force of a vehicle, and a braking force of a vehicle, different characteristics conformed to a stepping motion, a releasing motion, and a holding motion are determined on the basis of a pedal effort and predetermined characteristics of a pedal reaction force, and characteristics in a holding motion are changed according to vehicle information and environmental information.
Claims34
A pedal system comprising a pedal, an actuator, and pedal effort detecting means that detects a pedal effort, and capable of electrically controlling a pedal travel or a pedal reaction force,
- wherein the pedal system includes at least two kinds of thresholds that vary according to stepping on the pedal, and
- a pedal reaction force is changed in characteristics when a pedal effort is larger than a larger one (a threshold A) of the thresholds (a stepping motion), when a pedal effort is smaller than a smaller one (a threshold B) of the thresholds (a releasing motion), and when a pedal effort is between the threshold A and the threshold B (a holding motion).
A pedal system comprising a pedal, an actuator, and pedal effort detecting means that detects a pedal effort, and capable of electrically controlling a pedal travel or a pedal reaction force, wherein
- the pedal system includes at least two kinds of thresholds that vary according to stepping on the pedal, and
- a vehicle output is changed in characteristics when a pedal effort is larger than a larger one (a threshold A) of the thresholds (a stepping motion), when a pedal effort is smaller than a smaller one (a threshold B) of the thresholds (a releasing motion), and when a pedal effort is between the threshold A and the threshold B (a holding motion).
