Embodiment Construction
[0021] see figure 1 The vehicle body height intelligent control system of the present invention consists of an acceleration sensor 1, a CAN bus communication system 2, a gyroscope 3, a height sensor 4, a power supply module 5, a road surface unevenness identification system 6, a target height intelligent controller 7, and a vehicle body height controller 8 , a drive module 9, and a solenoid valve 10 for filling and deflation.
[0022] Acceleration sensor 1 is used to collect unsprung mass acceleration a t information and send it to the road surface roughness recognition system 6. The CAN bus communication system 2 is used for communication between the vehicle body height intelligent control system of the present invention and the vehicle CAN bus, so as to obtain vehicle speed v information from the vehicle CAN bus. The output end of the CAN bus communication system 2 is respectively connected to the input end of the road surface roughness identification system 6 and the targ...

The invention discloses a vehicle body height intelligent control system and method. An acceleration sensor, a CAN bus communication system, a gyroscope, and a height sensor send information collected during driving to a road surface unevenness identification system, a target height intelligent controller, and the vehicle body. Height controller, the road surface roughness identification system processes the received information and sends the road surface roughness information to the target vehicle height intelligent controller, and the target vehicle height intelligent controller processes the received information to obtain the current working condition Determine the most suitable vehicle height, and send the information to the vehicle height controller. The vehicle height controller processes the received information, sends a control signal to the drive module, and drives the inflation and deflation solenoid valve to perform the inflation and deflation operation to realize the vehicle body height. Adjustment, adjust the body height of the vehicle according to the driving conditions of the vehicle to ensure the effectiveness and accuracy of the body height adjustment process.
Description
technical field [0001] The invention relates to an air suspension system of a vehicle, in particular to its vehicle body height control system, which controls the automatic adjustment of the vehicle body height. Background technique [0002] The air suspension system has the characteristics of variable stiffness, low vibration frequency, and adjustable body height, which can effectively improve the ride comfort, handling stability and road friendliness of the vehicle. The traditional air suspension system uses a mechanical valve to control the height of the vehicle body, and adjusts the internal air pressure of the air spring according to the change of the load, so that the height of the vehicle body remains basically unchanged. When the air suspension adjusts the height of the vehicle body, the adjustment and maintenance of the vehicle body height is realized by controlling the mass flow of gas entering or flowing out of the air spring. The vehicle body height controller is...
