Problems solved by technology
However, after the safety tire with this structure travels for a certain distance, the sidewall will be torn under large deflection deformation and external force, resulting in the problems of tire rolling and bead falling off.
At this time, because the inner support device can rotate around the rim, the safety tire will slip, which affects the starting, acceleration, braking and other driving performance of the safety tire.

Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0020] Such as figure 1 A slip rate-based safety tire inner support device control method is characterized in that it comprises the following steps:
[0021] Before the vehicle starts, the tire pressure detector detects the initial tire pressure and judges whether the tire pressure is within the safe working tire pressure range. If the tire pressure value is within the safe working tire pressure range, the control system executes the inner support device locking command, namely The inner support device cannot rotate around the rim; if the detected tire pressure exceeds the range of safe working tire pressure, the system controls the alarm to issue a tire pressure warning and controls the vehicl...

The invention discloses a slippage rate-based safety tire inner support device control method which comprises the following steps: when a vehicle runs, monitoring the tire pressure of tires in real time through a tire pressure detector, and controlling an inner support device to rotate or be locked according to the size of the tire pressure; and then, calculating a tire slippage rate according to the data acquired by a vehicle running data acquisition system, and controlling the inner support device to rotate or be locked according to the size of the slippage rate. The slippage rate-based safety tire inner support device control method and system provided by the invention can improve the driving reliability of safety tires under different working conditions and have the advantages of simplicity, reliability and convenience.
Description
technical field [0001] The invention relates to a control method and system for a safety tire inner support device based on slip ratio, and belongs to the technical field of safety tires. Background technique [0002] Automobile safety tires are also called run-flat tires or anti-explosion tires. When a tire blows out during driving, it can effectively avoid traffic accidents caused by the out-of-control vehicle driving at high speed. The inner support type safety tire is a kind of representative safety tire. Under normal driving conditions, the support device installed inside the tire does not participate in the force of the wheel; when the tire is punctured and deflated, the tire relies on the support device inside the tire to bear the force of the wheel, thereby ensuring that the vehicle can continue to drive at a certain speed considerable distance. However, there is such a serious disadvantage in the inner support type safety tire, that is, after the tire blows out or...
