- A high-function safety feature that detects wheel nut loosening to prevent wheel detachment accidents, unlike anything seen before. - Self-diagnostic functions required for car sharing.
Wheel nuts and bolts tightened with inappropriate torque gradually loosen due to vibrations during driving. LWI detects the loosening of wheels caused by the loosening of nuts and bolts and informs the driver, thereby reducing the likelihood of wheel detachment accidents. In many cases, wheel detachment is caused by using bolts and nuts of different specifications when fitting non-standard tires, resulting in either excessive or insufficient tightening torque. LWI utilizes the wheel speed signal analysis technology developed through TPI to extract noise components correlated with bolt loosening, allowing it to inform the driver or vehicle manager which of the four wheels is at risk of detachment. It has high robustness against variations in tire wear, changes in passenger load, and individual differences in driving style, making it compatible with all types of tires and rims. Since it does not require additional sensor hardware, it achieves high safety and customer satisfaction with zero cost for raw materials and low integration costs.
