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.
Claims8
A method for determining a temperature of an inner liner of a tire of a motor vehicle, said method comprising:
- measuring an ambient temperature surrounding the motor vehicle;
- measuring a temperature of an inflation air of the tire;
- determining a saturation temperature of the inner liner of the tire as a function of the ambient temperature, as a function of the temperature of the inflation air of the tire and as a function of vehicle movement dynamics variables,
- determining the temperature of the inner liner of the tire by integration as a function of the determined saturation temperature of the inner liner of the tire.
A control device for determining a temperature of an inner liner of a tire of a motor vehicle, said control device being configured to:
- measure an ambient temperature surrounding the motor vehicle;
- measure a temperature of an inflation air of the tire;
- determine a saturation temperature as a function of the ambient temperature, as a function of the temperature of the inflation air of the tire and as a function of vehicle movement dynamics variables for the inner liner of the tire, and
- determine the temperature of the inner liner of the tire as a function of the calculated saturation temperature of the inner liner of the tire by integration.
