Abstract

A tire pressure measuring module for a vehicle tire includes a receiving space in which are disposed a pressure sensor, a control circuit coupled to the pressure sensor and a transmitter for wireless transmission of data from the control circuit to a vehicle side receiver. The receiving space is designed to be attached to the vehicle tire. The control circuit has programmable storage devices and a programming interface for writing on the storage device is designed with contact areas. The contact areas are galvanically contacted by contact pins of an associated programming device. The contact areas are covered by an elastic insulating layer which is designed so that it can be perforated by the contact pins.

Claims

1. A tire pressure measuring module for a vehicle tire, wherein the tire pressure measuring module has a receiving space, wherein, disposed in the receiving space, are:

a pressure sensor, a control circuit coupled to the pressure sensor, and a transmitter, designed for wireless transmission of data from the control circuit to a vehicle-side receiver,

wherein the receiving space is designed to be attached to the vehicle tire,

wherein the control circuit includes a programmable storage device,

that a programming interface for writing on the storage device is designed with contact areas, wherein the contact areas are provided for contact pins of an associated programming device to make direct electrical contact,

wherein the contact areas are covered with an elastic insulating layer, which is designed such that it can be perforated by the contact pins for programming.

2. The tire pressure measuring module according to claim 1, wherein the elastic insulating layer is made of a casting compound, in particular a malleable casting compound with a Shore A hardness of 80 or less.

3. The tire pressure measuring module according to claim 1, wherein the insulating layer is designed as a self-repairing insulating layer.

4. The tire pressure measuring module according to claim 1, wherein the contact areas are designed as contact surfaces.

5. A system having a tire pressure measuring module according to claim 1, and a programming device, wherein the programming device has a plurality of contact pins that are aligned spaced apart from one another, and are fixed with respect to one another, wherein the contact pins are arranged in their positions in relation to one another according to the contact areas of the tire pressure measuring module, such that each of the contact pins contacts an associated contact of the tire pressure measuring module when the tire pressure measuring module and the programming device are moved with respect to one another such that the contact pins perforate the insulating layer.

6. The system according to claim 5, wherein the programming device and the receiving space of the tire pressure measuring module are shaped or contoured as accurately-fitting counterparts, such that a perforation of the insulating layer is only possible when the contact pins are oriented over the contact areas.

7. The system according to claim 5, wherein the contact pins are mounted elastically in an axial direction, such that a uniform and simultaneous contacting of the contact areas is ensured.

8. The tire pressure measuring module according to claim 2, wherein the malleable casting compound has a Shore A hardness of 50 or less.

9. The tire pressure measuring module according to claim 2, wherein the malleable casting compound has a Shore A hardness of 30 or less.

10. A tire pressure measuring module for an associated vehicle tire, the tire pressure measuring module comprising:

a housing including a receiving space, wherein, disposed in the receiving space, are a pressure sensor, a control circuit coupled to the pressure sensor, and a transmitter, designed for wireless transmission of data from the control circuit to an associated vehicle-side receiver,

wherein the housing is designed to be attached to the associated vehicle tire,

wherein the control circuit includes a programmable storage device,

wherein a programming interface for writing on the storage device is designed with at least one contact area, wherein the at least one contact area is provided for a galvanic contacting via at least one contact pin of an associated programming device,

wherein the contact area is covered with an elastic insulating layer, which is designed such that it can be perforated by the at least one contact pin for programming by the associated programming device.
