Abstract

The present invention provides a method and system for electronic shock absorbing by adjusting the retractile status of a retractable absorber, wherein an acceleration sensor is fixed on a vehicle body at a predetermined direction and angle to detect the signal of acceleration vectors both along the vertical direction and along the longitudinal and transverse direction of the vehicle, and then transmit the signal to an information processing and controlling device to set the retractile status of the retractable absorber to realize shock absorbing. By the method or system of this invention, the nutation or lift of the vehicle can be decreased when starting or braking, the list can be decreased also when the vehicle is turning as the system can voluntarily adjust the burthen on the right and left sides of the wheels, and the impact to the wheels by the bumpy road and the noise thereof can be reduced too; at the same time, when the vehicle is turning, a safety list will arise and the highness of the vehicle can be adjusted by the power of oscillation between the wheels and the body of the vehicle, thus the security and passing ability of the vehicle is improved.

4. The method of claim 2, wherein the retractable absorber is set to only shorten by getting through a down check valve of a three-position two-way electromagnetic valve inside the retractable absorber;

the retractable absorber is set to only elongate by getting through an up check valve of the three-position two-way electromagnetic valve; and

the retractable absorber is set to un-shorten and un-elongate by setting the three-position two-way electromagnetic valve to block its channels.

5. The method of claim 1, wherein the method further comprising a step S4:

controlling the retractile status of the retractable absorber by the IPCD to absorb the shock of a vehicle, thus to avoid or decrease the harmful list and nutation or lift, at the same time adjusting the retractile length of the retractable absorber utilizing the power of vibration between the wheels and the vehicle body to realize the adjustment of the highness and inclination of the vehicle.

6. The method of claim 5, wherein said step S1 further comprising a step of fixing a highness sensor on the vehicle body to detect a variation signal of highness of the vehicle, and then in the step S4, the shock absorbing is achieved by, transmitting the vehicle highness signal from the highness sensor to the IPCD, then the IPCD adjusting the retractile status of the retractable absorber, and at the same time, adjusting the retractile length of the retractable absorber utilizing the power of vibration between the wheels and the vehicle body, thereby the highness and gradient of the vehicle is adjusted;

or the shock absorbing is achieved by, further fixing a speed sensor on the vehicle to detect a speed signal in step S1, then transmitting the speed signal to the IPCD to adjust the retractile status of the retractable absorber according to the road condition information expressed by the speed signal and the acceleration signal, and at the same time, adjusting the retractile length of the retractable absorber by the power of vibration between the wheels and the vehicle body to adjust the highness of the vehicle automatically.
