Problems solved by technology

[0006] However, this results in the driver of the vehicle having to leave the ignition key in the vehicle during his service work at a petrol station etc. in case the tire filling pressure may need to be corrected
[0007] Due to such circumstances, motor vehicles are subject to an increased risk of theft during the work of the vehicle driver

Embodiment Construction

[0042] first reference figure 1 . The figure shows a motor vehicle K with four tires 10 equipped with measuring electronics 11 .

[0043] Measuring electronics 11 is self-sufficient in terms of supply voltage from the on-board network voltage of motor vehicle K and is designed to measure tire pressure P present in tire 10 , tire temperature T and wheel speed n.

[0044] Measuring electronics 11 also has a transmitter, not shown in detail, by means of which data packets D can be transmitted wirelessly to a tire pressure check controller (RDK controller) 12 . Furthermore, the RDK controller 12 has on its part a receiver which is not shown in detail.

[0045] The RDK controller 12 is an integral part of the vehicle-mounted network composed of multiple CAN buses, and different controllers are interconnected via the vehicle-mounted network.

[0046] For example, two CAN buses CAN1 and CAN2 are shown, which are connected to one another via a gateway 13 .

[0047] The additionall...

Abstract

The invention relates to a method for monitoring the air pressure (p) in at least one tire (10) of a motor vehicle (K), wherein it is detected by means of at least one measuring electronics (11) present in the tire (10) At least one air pressure (p) in the tire (10) and data (D) are transmitted by the measuring electronics (11) to a control unit (12), wherein the control unit (12) operates the motor vehicle ( K) components (14, 15) to produce visual and / or auditory signals. According to the invention it is proposed that the control unit (12) is switched over a certain period of time into an inertial mode when the ignition of the motor vehicle (K) is switched off, in which the control unit (12) reads from the measuring electronics (11) The data (D) are further received and components ( 14 , 15 ) of the motor vehicle can be actuated on the basis of the data (D) to generate visual and / or audible signals. This makes it possible to carry out an active tire pressure change by the driver of the vehicle even with the ignition key removed, thereby reducing the risk of theft and the load on the battery during such a procedure.

Description

technical field [0001] The invention relates to a method for monitoring the air pressure in at least one tire of a motor vehicle. Background technique [0002] Such a method is known, for example, from DE 10 2008 003 845 A1. Here, the data measured by the tire measuring electronics, such as pressure and temperature, are transmitted wirelessly to the central control unit. After evaluating the received measurement data, the control unit transmits corresponding information or commands to a suitable display device. Speech output or use of sound signals has also been proposed. [0003] WO 2011 / 004229 A1 describes a tire pressure monitoring system in which turn signal lights or warning flashers are actuated by a control unit in order to generate a visual and / or audible warning signal based on the measured tire pressure and Vehicle horn. [0004] The measurement data transmitted wirelessly by the measuring electronics located in the tire are transmitted with a certain transmiss...
