DETECTION OF UNDER-INFLATED TIRES

摘要

Methods and systems of detecting under-inflated tires are described. An actual radius may be computed based on vehicle speed and wheel speed for each of the tires (104) of the vehicle (100). An actual pressure state  from a low pressure state  a normal pressure state  and a high pressure state  is assigned to the each of the tires (104) based on a comparison of the actual radius with a reference radius  such that actual pressure states of the each of the tires (104) together correspond to an actual combination pattern. The actual combination pattern is compared with predefined combination patterns. The predefined combination patterns are indicative of a possible combination of pressure states of the each of the tires (104) of the vehicle (100)  which are differentiated based on drive-axle tires and non-drive axle tires. Furthermore  position of at least one under-inflated tire is identified based on the comparing.
