Abstract
In a pedal operation amount detecting apparatus, a brake pedal and a crevice fixed to an end portion of an operation rod are rotatably coupled by a coupling shaft, a bush is interposed between the brake pedal and the coupling shaft, and detectors are mounted on an outer peripheral surface of a bush body, which is elastically deformable, in the bush, and an ECU estimates an angle between the brake pedal and the operation rod based on a ratio between distortion loads detected by the detectors, and calculates an operation amount of the brake pedal, that is to say, pedal force and a pedal stroke, based on the angle, thereby enabling to improve mountability by simplifying a configuration and to detect the operation amount with a high degree of accuracy.
Claims11
A pedal operation amount detecting apparatus for detecting a pedal operation amount transmitted to an operation target unit by converting rotational motion of an operation pedal to linear motion of an operation rod, the apparatus comprising:
- an angle estimating unit that estimates an angle between a first straight line connecting a rotation center of the operation pedal and a coupling point of the operation pedal and the operation rod and a second straight line along a linear motion direction of the operation rod;
- and
- a pedal operation amount calculating unit that calculates a pedal operation amount based on an angle estimated by the angle estimating unit.
