Abstract:
Disclosed are a sensor for measuring the height of a vehicle, a device for measuring the height of a vehicle, and an active electronic control system of the air suspension of a commercial vehicle. The sensor for measuring the height of a vehicle according to an embodiment of the present invention includes a socket fixated to a vehicle body; a housing unit joined to the socket; a lever module which is joined to the housing unit and wheels of the vehicle and is relatively rotated around the housing unit according to a change in the height of the vehicle; and a sensing module which is joined to the housing unit and which senses an electromagnetic change caused by the rotation of the lever module. According to the embodiment of the present invention, an impact on the sensing module can be prevented because the sensing module, which power is supplied, is fixated to the vehicle body while the mechanical movement is generated only in a plate unit connected to the wheels of the vehicle.
