摘要： A drive-by-wire non-contact capacitive throttle control apparatus and method of forming the same. A capacitive position sensor is provided, which includes a stationary electrode and a rotatable electrode. The rotatable electrode can be attached to a throttle lever such that the rotatable electrode rotates as the throttle lever rotates. The capacitance between the rotatable electrode and the stationary electrode varies with the position of the throttle lever. The position of the throttle lever can be measured by measuring the capacitance between the electrodes and a signal can be generated based on the sensed position. The signal can be electrically transmitted to an ECU (Electronic Control Unit) utilizing one or more electrical wires. The signal can be sent in the form of a varying voltage, which in turn controls the throttle of a vehicle.
