Applicable vehicle type: For Volvo
The automotive height sensor (also known as the body height sensor, axle height sensor, or vehicle attitude sensor) is a core component of modern automotive electronic control suspension systems and lighting systems. It is primarily used to monitor real-time changes in the height between the body and the chassis, and transmit signals to the electronic control unit (ECU) to achieve functions such as automatic adjustment of vehicle body attitude and horizontal control of headlights. This sensor is typically installed at the front axle and rear axle positions, and can accurately measure angular changes during the suspension compression and rebound processes.
1. Air Suspension System
Real-time monitoring of the axle height, the ECU activates the air compressor based on the signal to supply pressure to the air springs, achieving automatic adjustment of the vehicle body level.
2. Adaptive Front-lighting System (AFS)
Detects the vehicle's pitch angle and automatically adjusts the headlight illumination height to avoid glare from oncoming vehicles, enhancing driving safety at night.
3. Active Suspension and Damping Control
In conjunction with acceleration sensors, it dynamically adjusts the suspension stiffness and damping to improve handling and comfort.
