Method for detecting under-inflation of pneumatic tire of wheel of utility-type vehicle that is utilized for carrying loads, involves detecting variation of load of vehicle, and executing request for initialization of detection function

摘要

The method involves supplying information to a controller (30) using a wheel rotation speed sensor (32), where the controller implements an under-inflation detection function (36) using a method for frequency analysis of speed oscillations. The information is output to a load (44) of a vehicle (42) using a load sensor (38) to control a function of the load of the vehicle. A notable variation of the load of the vehicle is detected each time by the control function of the load of the vehicle. A systematic reinitialization request (46) is executed for initialization of the detection function. An independent claim is also included for a motor vehicle.
