Patent ID: 8825267

Claim:
An indirect tire pressure monitoring method of detecting tire pressure deviation in tires of a vehicle, comprising: determining tire pressure indicating data indicative of a tire pressure condition of at least one tire of a vehicle; and determining tire pressure deviation data indicative of a tire pressure deviation condition in the at least one tire on the basis of the tire pressure indicating data; characterized by: obtaining at least one vehicle data provided by a controlling and/or monitoring device of the vehicle; determining suspension related data on the basis of the at least one vehicle data; and suspension related compensating on the basis of the suspension related data such that suspension compensated tire pressure deviation data is achieved, wherein the suspension related data includes at least one of (i) a current pressure in a suspension acting on the least one tire, and (ii) a height of the suspension acting on the least one tire, and wherein the at least one vehicle data includes at least one of vehicle data indicative of suspension stiffness acting on at least one of the at least one tire; vehicle data indicative of operation of a semi-active or active suspension control system of the vehicle; vehicle data indicative of at least one of a lateral acceleration and a longitudinal acceleration of the vehicle; vehicle data indicative of a yaw rate of the vehicle; vehicle data indicative of a speed of the vehicle; vehicle data indicative of a steering wheel angle of a steering wheel of the vehicle; vehicle data indicative of at least one of positioning, orientation and emission direction of at least one head light of the vehicle; vehicle data indicative of a braking condition of the vehicle; vehicle data indicative that a braking system of the vehicle is operating; vehicle data indicative of brake pressure; vehicle data indicative that at least one active control device of the vehicle is active; vehicle data indicative of ambient temperature; vehicle data indicative of an engine torque of an engine of the vehicle; vehicle data indicative of a torque acting on the at least one tire; vehicle data indicative of wheel slip related to the at least one tire; vehicle data indicative of an engine speed of an engine of the vehicle; and vehicle data indicative that a gear shift of the vehicle is in progress.
