Present invention combination vehicle sensors, ECU, power supply and relay, provide a kind of overall height adjustment system, and Fig. 2 is application
The structural schematic diagram of a kind of overall height adjustment system of height regulator for vehicle of the present invention, as shown in Fig. 2, overall height of the invention adjusts system
System includes:
Vehicle dynamics sensors 11: to electronic control unit (Electronic Control Unit, referred to as: ECU) 12 hairs
Send vehicle multidate information.Vehicle dynamics sensors 11 collect the multidate information of the various aspects of vehicle, such as overall height, speed, angular speed
Etc..The vehicle multidate information of collection is sent to ECU11.Vehicle dynamics sensors 11 include accelerating position sensor, braking
Sensor, rotation sensor, vehicle speed sensor, angular-rate sensor and vehicle height sensor (including it is left front, left back, right before and it is right
Afterwards).
ECU12: output current value signal is determined according to vehicle multidate information and sends output current value signal to power supply 13.
Further, it can also be that driver selects car driving mode (such as off-road mode or general traveling according to personal interest
Mode or the preferential driving mode of comfort) after, ECU12 determines defeated according to the car driving mode that vehicle multidate information and driver select
Out current value signals and to power supply 13 send output current value signal.
Power supply 13: output output current value signal.
Relay 14: the output current value signal that power supply 13 is exported is passed to height regulator for vehicle 15.As shown, corresponding four
A wheel has 4 relays.
Height regulator for vehicle 15: overall height adjustment is carried out according to the output current value signal.
The quantity of relay 14 and the quantity of height regulator for vehicle 15 are all determined by the quantity of wheel, such as have 4 wheels,
Then the quantity of relay 14 and the quantity of height regulator for vehicle 15 are also 4.
Overall height adjustment system of the invention in actual use, can distinguish height regulator for vehicle 15 according to the quantity of wheel
It is mounted on the corresponding position of each wheel, as follows the following detailed description of the operation principle and process of overall height of the present invention adjustment system:
The multidate information of the various aspects of the collection of vehicle dynamics sensors 11 vehicle first sends vehicle dynamic to ECU12 and believes
Breath, ECU12 determine output current value signal according to vehicle multidate information and send output current value signal to power supply 13.Alternatively,
After driver selects car driving mode according to personal interest, car driving mode that ECU12 is selected according to vehicle multidate information and driver
It determines output current value signal and sends output current value signal to power supply 13.Power supply 13 exports output current value signal, finally
The output current value signal that relay 14 exports power supply 13 is passed to height regulator for vehicle 15.In each height regulator for vehicle 15
Magnetic cylinder A inside the first electromagnet 1 and the second electromagnet 2 receive wheel power supply output electric current after so that permanent magnetic
Iron generates repulsive force, and the performance number of electromagnetism changes, causes the position of connecting rod 6 to change, cause to be connected with mounting plate 9
Vehicle body, the knuckle being connected with mounting bracket 10 position can also change, therefore with regard to capable adjusting wheel height, and
External impact can also be cut down, the piston in hydraulic cylinder is cooperated to play the effect of damper at the same time, it is final to can be achieved according to reality
Border driving condition arbitrarily adjusts overall height, and has both damping effect simultaneously, and comfort by bus and the stability driven can be improved.Also
It can be achieved arbitrarily to adjust overall height according to the selection of driver and actual travel situation, be adjusted to driver and select car driving mode.
Overall height adjustment system of the invention not only passes through simply construction and plays the role of fluid pressure type traveller assembly, but also has
The function of the standby electronic controlled suspension for actively adjusting overall height.
Specifically, when the mode that driver selects is off-road mode, for ensure dynamic drive sense and prevent vehicle body and
Irregular road surface (non-paved road) contact is it is necessary to improve overall height.The magnetic force of the second electromagnet 2 and output electric current can be enhanced at this time
Value is higher than the first electromagnet 1, holds up the mounting plate 9 (mounting plate 9 is connected with vehicle body) connected with connecting rod 6 upwards and improves vehicle body.
When the mode that driver selects is general driving mode, to realize buffering road surface punching that existing hydraulic system has
It hits and the general action of elasticity, the current value for being delivered to the first electromagnet 1 and the second electromagnet 2 tends to be balanced, during vehicle body is in
Between position, only play the function of basic traveller assembly at this time.
When the mode that driver selects driving mode preferential for comfort, in order to realize paved road peace and quiet and feel by bus
Superior riving condition reduces the height of vehicle body and road surface as far as possible.Overall height and off-road mode should be reduced antithesis at this time, the
The current value of one electromagnet, 1 to the second electromagnet 2 is big, and magnetic force enhances the mounting plate 9 (connecting with vehicle body) being connected with connecting rod 6
It pulls down, vehicle body decline, overall height reduces.
Overall height provided by the invention adjusts system, the height regulator for vehicle designed by electromagnetic type, in conjunction with vehicle sensors,
ECU, power supply and relay can mention, it can be achieved that arbitrarily adjust overall height according to actual travel situation, and have both damping effect simultaneously
High comfort by bus and the stability driven.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
