A control that can be a throttle control of a handle-bared vehicle is presented. According to some embodiments, a control can include a plurality of circuit boards, each of the circuit boards including a transmission coil, sensor coils, and control circuitry the drives the transmission coil and receives signals from the sensor coils; and one or more targets mounted on a shaft and configured to rotate over the sensor coils of the plurality of circuit boards as the shaft is rotated, wherein the plurality of circuit boards are mounted around the shaft, and wherein the position of the target is determined by the control circuitry as the shaft is rotated.

The invention discloses an inductive torque sensor and a combined inductive torque and angle sensor for position sensing. The object of the invention to propose a torque sensor as well as a combined torque and angle sensor which does not require a shielding of the sensor PCB and which can provide a plausibility check of the torque sensor when using only three sensors will be solved by an inductive torque sensor for detection of torque movements comprising a stationary printed circuit board (PCB) with sensing coils, a primary target and a secondary target, whereas the primary target and secondary target each comprise of different metallic patterns, whereas each target covers 50% of the sensing coils and the combined coverage of both targets varies between 50% and 100% depending on the relative position between the two targets. The objective is also solved by a combined inductive torque and angle sensor comprising a primary target wheel, a secondary target wheel and a torsion beam, whereas the primary target wheel is centrally stacked on the torsion beam and comprises a metallic pattern for a steering angle 360&#xb0; single-turn sensor and a first metallic pattern for the torque sensor, and the secondary target wheel comprises a second metallic pattern of the torque sensor.
