The invention provides an angular position sensor, an angular position measurement system and an angular position measurement method. The angular position sensor comprises an excitation coil, M receiving coils and a rotor, wherein the M receiving coils are coaxial with the excitation coil. The M receiving coils, a first capacitor and an operational amplifier form an LC oscillation circuit, and two adjacent receiving coils have a deflection angle therebetween, wherein M is a positive integer greater than or equal to 2. By using a relation between a rotating angle of the rotor and output signals of the M receiving coils, the rotating angle of the rotor can be acquired under the premise of acquiring the output signals of the M receiving coils, and thus measuring angle variations is realized. The rotor is not contacted with the receiving coils, that is, mechanical wear does not exist, so that the weather resistance and the vibration resistance of the angular position measurement system are improved. Meanwhile, the cost can be effectively reduced.
Description
technical field [0001] The invention relates to the field of electromechanical control, in particular to an angle position sensor, an angle position measurement system and a method. Background technique [0002] Angular position sensors are widely used in automobiles, such as liquid level sensors, accelerator pedals, throttle bodies, power steering, body level sensors, etc. At present, on the existing auto parts, the main angle position sensors are potentiometer contact angle sensor and Hall type non-contact angle sensor. [0003] The potentiometer angle sensor is a contact sensor that was often used in the early days. It changes the position of the contact point on the resistive film, thereby changing the ratio of the upper and lower resistances, and realizing the change of the output terminal voltage with the external position. However, the potentiometer-type angle sensor inevitably has the problem that the contacts and the resistive film are easy to wear, and if dirt suc...
