The main functions of the body active control system include folding normal working function, folding engine closing function, folding wake up function, folding key opening function, folding locking position function.
The details are as follows: when the engine is running or the vehicle is running, if the vehicle load increases and the body height decreases, the ABC module will activate the relevant solenoid valve, so that the hydraulic oil is transmitted to the shock absorber, and the body will return to the original level;
If the load decreases and the height of the body increases, the ABC module will activate the relevant solenoid valve to make the hydraulic oil flow out of the shock absorber and keep the level of the body unchanged.
When the engine is turned off for 1min, the ECU monitors the body level. If the load decreases and the body rises, the ECU will adjust the body level, but it can only reduce the body level to prevent excessive power consumption.
When the engine is turned off for 1min, the ECU will go to sleep. When the remote control is operated, the door is opened or the trunk cover is opened, the ABC ECU will be awakened for body level monitoring. If the load is reduced and the body is raised, the ECU will adjust the body level.
Because the engine did not start running, it can only reduce the level of the body.
When the ignition switch is on, it works the same as the wake-up function, except that there is no time limit.
When the vehicle is stopped and the engine is not running, if the system detects that the wheels are not loaded or the load is reduced (e.g. when changing a tyre or on a lift machine), all the cross-ratio valves will be closed to maintain the same level of the body.
It is worth noting that the body level may decrease when the vehicle has been idle for a period of time.
When the vehicle is idle for a long time (about 4 weeks), the body level may slowly decrease, but should not exceed 30mm.
When the vehicle is running, ABC oil will work under normal operating temperature. After parking, the oil temperature will decrease, so that the level of the vehicle will decrease, but it should decrease slowly and the decrease amount should not exceed 20mm.
The driver can use the body level adjustment button to select the normal body level, high body level or higher body level, but when the vehicle speed exceeds a certain speed, the operation of raising the body level will be canceled automatically.
When the vehicle speed decreases, the system will automatically resume the raising operation.
ABC suspension pillar is mainly composed of hydraulic plunger, spring and shock absorber.
ABC suspension struts and hydraulic plunger travel sensors are integrated into the hydraulic plunger.
The shock absorber adopts double tube pneumatic design.
When the vehicle is running, the low-frequency vibration below 5Hz will be absorbed by the ABC suspension prop hydraulic plunger;
Vibrations above 5Hz will be absorbed by the shock absorber.
In this way, it can reduce the body jump and acceleration caused by the uneven road, or the body swaying back and forth during braking, or the roll or roll caused by the lateral tilt of the steering and road.
