Powder-water mixed liquid；
Current control unit, it connects entire car controller, on-vehicle battery and first, second resistance wire respectively, and by adjusting
Section on-vehicle battery is transmitted to the size of current of resistance wire to adjust the caloric value of resistance wire, and current control unit is configured as：
Driver's operation information from entire car controller is received, when driver's selection driving model is motor pattern, electricity
Flow control unit only makes second resistance silk heating power, increases the viscosity of the second heated liquid, and the hardness of conveyor screw is improved, and is made
Suspension more meets the driving demand of motor pattern；When driving model is switched to comfort mode, electric current by driver by motor pattern
Control unit only makes first resistor silk heating power, reduces the viscosity of the first heated liquid, the hardness reduction of conveyor screw, makes to hang
Frame more meets the driving demand of comfort mode；
Under comfort mode, current control unit also receives the vibration signal from chassis shock sensor, when vibrations width
Degree is more than predetermined value and the duration exceedes scheduled duration, shows that vehicle is just travelled on the road surface more jolted, now electric current
Control unit tunes up the current value of supply first resistor silk, and making the hardness of conveyor screw further reduces, so as in the traveling jolted
Preferably comfortableness is maintained on road surface, exceedes scheduled duration, electricity when vibration amplitude is less than predetermined value and duration
Current value is reverted to initial size by flow control unit.
Current control unit also receives the signal from front truck radar, current vehicle radar detection to vehicle front preset range
Inside there is barrier, vehicle needs to carry out brake hard immediately, and brake hard will bring the pitching by a relatively large margin of vehicle body, be
Suppress this pitching as far as possible, then no matter which kind of current driving model is, current control unit all only makes second resistance silk logical
Electricity.
By means of the invention it is possible to its hardness is dynamically adjusted according to driver's operation information and running condition information, so that
The soft or hard degree of electric vehicle suspension is more met the requirement of driving, optimize driving experience, and it is relative to air spring
