An electronically controlled automotive air suspension system is designed to maintain a level ride height automatically. When a heavy payload is placed in the cargo area, the rear of the vehicle squats. Arrange the following system operations in the correct chronological order to demonstrate how the active suspension restores the vehicle to its proper trim height.
- 1The added payload compresses the rear suspension, altering the physical angle of the linkages attached to the ride height sensors.
- 2The ride height sensors translate the mechanical linkage change into an electrical voltage signal sent to the suspension control module.
- 3The suspension control module processes the sensor voltage, determines it falls below the programmed target value, and triggers the compressor relay.
- 4The air compressor pressurizes the pneumatic lines while the control module simultaneously commands the rear air spring solenoid valves to open.
- 5Pressurized air inflates the rear air bladders, raising the chassis until the sensors report the correct trim height, causing the system to shut off.
Cevap
The correct sequence starts with the physical compression under load, followed by the sensors sending an electrical signal. The control module then processes this signal and triggers the relay. Next, the compressor activates and valves open, allowing air to finally inflate the bladders and restore ride height.
The active air suspension operates on a standard closed-loop control system. It begins with a physical change (compression), which is converted to an electrical signal by the sensors (input). The control module evaluates this data (processing) and activates the compressor and valves (output). Finally, the system achieves physical correction (inflation) which is verified by the sensors, closing the loop.
