Abstract

A method for operating a tire pressure monitoring system of a motor vehicle, including a direct or indirect sensing device for sensing and outputting the pressure which is present in the motor vehicle tires. In order to assist the driver of a vehicle when inflating a tire, a loudspeaker, which is present on the motor vehicle, is used to transmit the current pressure value (p_act) to the vehicle driver by a voice message. In this context, the voice message includes the current pressure values (p_act) in increments of 0.1 bar. The loudspeakers, which are present, are the loudspeakers of the vehicle'"'"'s own multimedia system or a loudspeaker of the vehicle'"'"'s own alarm system.

Claims

1. A method for operating a tire pressure monitoring system of a motor vehicle, comprising the steps of sensing and outputting a pressure (p_act) which is present in a tire of the motor vehicle using a direct or indirect sensing device, and transmitting a current pressure value (p_act) to the vehicle driver by means of a voice message using a speaker which is present on the motor vehicle.

2. The method as claimed in claim 1, wherein the voice message is configured to be output in a multilingual fashion, and a language of the transmitted information is configured to be selected.

3. The method as claimed in claim 1, wherein the speaker is a speaker of a multimedia system of the vehicle or a speaker of an alarm system of the vehicle.

4. The method as claimed in claim 1, further comprising the step of outputting information about a position of the tire at which a change in the current pressure value (p_act) is detected.

5. The method as claimed in claim 1, wherein the voice message outputs the current pressure values (p_act) in increments of 0.1 bar.

6. The method as claimed in claim 1, wherein output signals of the direct or indirect sensing device are transmitted to a control unit and processed and amplified by an amplifier of a multimedia system of the vehicle.

7. The method as claimed in claim 6, wherein the output signals of the direct or indirect sensing device are transmitted to the control unit in a wireless fashion.

8. The method as claimed in claim 1, wherein the current pressure value (p_act) represents a differential pressure value or an overpressure value in relation to an ambient pressure.
