Method for monitoring the load of vehicle tires

摘要

The invention relates to a method for monitoring the load of vehicle tires which are each contacting a pavement with a circumferential section during travel, by means of monitoring devices (4) which are mounted to the tire (1) and contain a transmitter and a generator which is driven by the flexion of the tire (1), said flexion occurring during vehicle operation, wherein the generator generates a first voltage pulse each time it reaches the beginning of the circumferential section of the tire (1), which is contacting the pavement, and generates a second voltage pulse each time it reaches the end of the circumferential section of the tire (1), which is contacting the pavement, the time intervals (t1) between first and second voltage pulses are measured, the time intervals (t1) or a value calculated therefrom are/is compared with a reference value, and a warning signal is generated if a difference detected in this comparison exceeds a predefined value.

1. A method for monitoring vehicle tire load, the tire having contact with pavement along a circumferential section during rotation, the method comprising:
generating a first signal at a beginning of tire/pavement circumferential section contact using a monitoring/signaling device mounted to the tire; generating a second signal at an end of tire/pavement circumferential section contact using the monitoring/signaling device; measuring a time interval between the first and second signals; comparing the time intervals or a value calculated therefrom with a reference value; generating a warning signal if a difference detection in the comparison exceeds a predetermined value; and evaluating the time intervals to determine a tire lift off from the pavement and that, if a lift off is detected informing a dynamic drive control system of the lift off.
