Abstract
A shifter includes a base and a driver interface module, such as a lever or knob, having a structural member attached to the base and held in a fixed position so that a handle on the structural member can be grasped and loaded by a vehicle operator. At least one load-measuring sensor, such as a strain gage, is attached to the structural member. The sensor outputs an analog signal in proportion to the load applied to the structural member by the vehicle operator. A circuit is connected to the load-measuring sensor for receiving the analog signal. The circuit is configured and programmed to output a transmission-shift control signal when the shift request signal reaches a predetermined minimum load value.
