Hard mode state is automatically become, until after gas pedal aperture is less than 70%, can just be restored to soft mode formula；When brake pedal is stepped on
When, system will also become hard mold formula, until loosening the brake, system can be restored again to soft mode formula.
Under this pattern, as speed ＜ 5km/h, system is hard mode state, and as 5km/h ＜ speed ＜ 100km/h, system is extensive
It is again soft mode state, speed ＞ 100km/h, system will automatically become hard mode state again.
Three, mode standard
Under mode standard, in vehicle travel process, system will collect three road body acceleration signals, be transported by integrating
The roads Suan Jiangmei vehicle body acceleration is scaled corresponding vehicle body velocities, and the body acceleration signal in each direction and vehicle body velocities are believed
Number a threshold value is calculated by certain algorithm, according to the size of this threshold value come adjust pwm signal be high duty ratio or
Low duty ratio, to realize intelligent automatic regulated damper damping size effect.The solenoid valve 107 of gas chamber is in and beats at this time
Open state, in this way we a good match point can be found between the damping of CDC dampers and the rigidity of air suspension, with
Just the ride experience taken into account vehicle body manipulation and comfortably had.
Under this pattern, if steering wheel angle is more than 40 degree, system will directly automatically become the state of hard mold formula, Zhi Daofang
After being less than 40 degree to disk corner, can just it restore to mode standard；When gas pedal aperture reaches 70%, system will be direct
Hard mode state is automatically become, until after gas pedal aperture is less than 70%, can just be restored to mode standard；When brake pedal is stepped on
When lower, system will also become hard mold formula, until loosening the brake, system can be restored again to mode standard.
Under this pattern, as speed ＜ 5km/h, system is hard mode state, and as 5km/h ＜ speed ＜ 100km/h, system is extensive
It is again mode standard state, speed ＞ 100km/h, system will automatically become hard mode state again.
A kind of vehicle, the vehicle are equipped with the above-described continuously adjustable control system 100 with variable rigidity of damping.
The utility model is by the way that on the basis of the air suspension of existing simple mechanical formula, mating intelligent damping is continuously adjustable
CDC dampers, and by adding a new gas chamber in the air spring of airsuspension system, pass through control gas chamber with it is empty
The connection of gas spring and the stiffness tuning for closing realization air suspension, to realize that vehicle damping is continuously adjustable and rigidity can
Become, coordinates the flexible control of ECU that can bring better ride experience to passenger.
It should be noted that because of vehicle difference, the quantity of the air spring in airsuspension system is also different, above-mentioned gas
Room, CDC dampers, solenoid valve 107 quantity can make and change according to the quantity of air spring in airsuspension system, not
Creativeness is paid, the change of gas chamber, 107 quantity of CDC dampers and solenoid valve is carried out according only to vehicle, in the utility model
Protection domain in.
The utility model is not limited to above-mentioned form of implementation, if the various changes or deformation of the utility model do not depart from
The spirit and scope of the utility model, if these changes and deformation belong to the utility model claims and equivalent technologies range
Interior, the utility model also includes these deformations and change.
