ABSTRACT:
A handlebar throttle controller includes a cylindrical housing adapted to be rotatably mounted to an end of a handlebar, and a rotary shaft supported within the housing for relative rotation about a longitudinal axis. A first spring angularly biases the shaft toward a first angular position, while at least one of a cam and follower arrangement and a friction element and reaction element arrangement generates a first torque characteristic resisting relative rotation of the shaft when the shaft is rotated in a first direction relative to the housing, and a second torque characteristic resisting relative rotation of the shaft within the housing when the shaft is rotated in a second direction relative to the housing. A sensor on the housing generates an electrical output representative of an instantaneous angular position of the shaft relative to the housing, for use, for example, in an electronic throttle control system.
