Abstract

The invention discloses an off-road vehicle tire central inflating and deflating system based on slip ratio control and a control method thereof. The off-road vehicle tire central inflating and deflating system comprises a slip ratio obtaining system and a tire central inflating and deflating system. The slip ratio obtaining system obtains the slip ratio and compares the slip ratio with a preset slip ratio range value, and inflating and deflating of tires are adjusted in this way. The tire central inflating and deflating system comprises an air supply and storage device, a rotary sealing device, tire inflating / deflating valves and corresponding pipelines. The slip ratio obtaining system comprises a signal collecting device and a control and display device. The control method of the off-road vehicle tire central inflating and deflating system mainly comprises a manual control method and an electronic control method. According to the off-road vehicle tire central inflating and deflatingsystem based on slip ratio control and the control method thereof, manual control or electronic control can be selected according to the intension of an operation driver, meanwhile, timely control over inflating and deflating operation of all the tires can be achieved according to the road surface condition in the actual traveling process of a vehicle, and the traction property and lateral stability of the vehicle in different terrains are improved.

Description

technical field [0001] The invention relates to an off-road vehicle tire central inflation and deflation system based on slip rate control and a control method, and belongs to the field of automobile tire central inflation and deflation systems. Background technique [0002] The off-road vehicle tire central inflation and deflation system is a system that can detect and adjust the tire pressure at any time while the car is running (or stopped). Its main function is: when the car passes through deserts, coastal beaches, swamps, muddy ground, soft ground, and ice and snow ground, the system can quickly reduce the tire pressure and increase the contact area of ​​the tire. On the one hand, the subsidence of the tire and the soil The resistance is reduced; on the other hand, due to the increase in the number of tire patterns embedded in the soil, the propulsive force of the soil is increased, the traction force is greatly increased, and the passability of the car is improved. Wh...
