  • Method and control device for determining a tire temperature
    Patent number: 10377192
    Abstract: A method for determining a temperature of a tire of a motor vehicle, specifically a temperature of an inner liner of the respective tire, having at least the following steps: a saturation temperature is determined for the inner liner of the respective tire as a function of an ambient temperature, as a function of a temperature of the inflation air of the respective tire and as a function of vehicle movement dynamics variables; the temperature of the inner liner of the respective tire is determined by integration as a function of the determined saturation temperature of the inner liner of the respective tire.
    Type: Grant

  • System and method for determining tire wear
    Patent number: 9921134
    Abstract: System for determining tire wear for tires of a wheeled motor vehicle including a direct tire pressure determination unit being configured to measure at least the tire pressure of the tires; an indirect tire pressure determination unit being configured to determine for at least some of the tires a roll radius factor corresponding to or depending from the roll radius of the respective tire; a tire force determination unit being configured to determine a vertical force factor corresponding to or depending from a vertical force applied to the tires; and a processing unit for determining the tire wear for such tires of the motor vehicle for which the indirect tire pressure determination unit provides the respective roll radius factor, namely by compensating the roll radius factor of the tires provided by the indirect tire pressure determination unit.
