Detailed description of the invention
Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
With reference to the schematic flow sheet that Fig. 1, Fig. 1 are tire condition detection method one embodiment of the present invention.In the present embodiment, institute
State tire condition detection method to include:
Step S10, when vehicle is in transport condition, launches multiple radar waves to the tire being in rotation status, and connects
Receive the radar wave of correspondence reflection；
In the present embodiment, for quantity, installation site, the type of radar wave and the transmitting of radar of radar transmit-receive device
Mode does not limits, and is configured with specific reference to being actually needed.The most each wheel or each group of corresponding radar transmit-receive device of wheel；
Such as radar transmit-receive device is arranged on vehicle chassis first-class.
Generally, the state of tire changes and the profile causing tire is accordingly changed, and even results in vehicle overall
Run-off the straight.The thickness causing tire is reduced by such as tire wear, namely the road clearance reduces；Such as, the tire pressure of tire is not
Foot, will cause tire to present flat change, namely tire becomes more to bend with ground contact portion.
Therefore, in the present embodiment, change the various features caused based on above-mentioned tire condition, by launching radar wave
Mode realizes the judgement to vehicle tyre state indirectly.
For avoiding radar wave consume in communication process, therefore, in the present embodiment, preferred emission power is higher, propagate road
Footpath is more biased towards the electromagnetic wave of straight line.Meanwhile, vehicle in the process of moving, if keep radar transmit-receive dress transmitting invariant position, then
Repeatedly launch radar wave and correspondence can detect the diverse location on tire, and then the reflection radar wave received for comprehensive each time, calculate
Corresponding radar emission point is to distance between radar reflection point on tire, or adjusts the transmitting angle of radar wave, to calculate
