Abstract

Method (V) for displaying a vehicle tire valve (1) on a display device of a mobile terminal (5), wherein an image of the vehicle tire is recorded by means of an image capture unit of the mobile terminal (S1), and a valve position in the recorded image is recognized by means of an image recognition unit ( S2), and the recorded image with a marking at the valve position is output on the display device of the mobile terminal (S3), with a radio connection (6) being present between the vehicle tire valve (1) and the mobile terminal, with a signal element on the vehicle tire valve ( 1) is controlled by the mobile terminal (5).

Description

The invention relates to a method for displaying a vehicle tire valve on a display device of a mobile terminal and a program product for execution on the mobile terminal.

For example, if air needs to be refilled on a vehicle wheel, the tire valve must be clearly visible and quickly located.

In DE 10 2017 215 180 A1 discloses a device for displaying technical information, a wheel system with the device and a vehicle wheel with the device. The device is intended to enable other road users to perceive various technical information about a vehicle in the traffic.

DE 10 2013 016 096 A1 shows a method for displaying a current operating state of a motor vehicle, in which image data from an external area of the motor vehicle is generated by a portable communication terminal using a camera.

Out of DE 10 2015 113 262 A1 A system for shared vehicles emerges.

In DE 10 2011 013 760 A1 A method for conveying information using augmented reality in connection with road vehicles, a computer program product and a portable device with which such information is conveyed are disclosed.

An object of the present invention is to provide a method and computer program product by means of which a user, e.g. a vehicle owner, can locate the vehicle tire valve more quickly and reliably.

The object is achieved by a method with the features of independent claim 1 and the independent, subordinate claim 7. Advantageous variants and developments of the invention are set out in the dependent claims.

According to the invention, the method is designed to display a vehicle tire valve on a display device of a mobile terminal. An image of the vehicle tire is recorded using an image capture unit of the mobile terminal. A valve position is recognized in the captured image using an image recognition unit. The captured image is displayed on the display device of the mobile terminal with a marking of the valve position.

The vehicle tire is, for example, a tire of a car or truck or another commercial vehicle, such as a wheel loader. It can also be the tire of a two- or three-wheeled vehicle. The display device of the mobile terminal is preferably designed as a screen or display, for example from a smartphone, a tablet, or a smartwatch, or another portable device, for example a diagnostic device in a vehicle workshop. A camera in the mobile terminal is preferably used as the image capture unit. The image recognition unit is advantageously designed as a function in software or a computer program product, with which the valve position is determined in the recorded image. It may be necessary or desirable for the user or vehicle owner to teach in the respective tire by taking an image and determining the valve position. The valve position can be marked by a colored circle or an arrow or another symbol.

In an advantageous embodiment, the marking for displaying the valve position is superimposed on the captured image, so that the user can see an image, preferably in photo quality, and the marking in the same image.

There is a radio connection between the vehicle tire valve and the mobile device. Preferably, the radio connection is listed as a Bluetooth connection or WiFi or ZigBee or NFC connection. The vehicle tire valve can include a radio module for establishing or maintaining the radio connection between the vehicle tire valve and the mobile terminal.

Advantageously, the captured image is updated regularly. For example, after a set period of time or flexibly, e.g. if the user has moved, the image is re-taken and the image recognition unit determines the valve position again or checks whether there is a deviation from the last determined valve position. If there is a deviation, the marking will be displayed in the new image taken. Advantageously, the valve position is displayed to the user even after the user moves, e.g. walking closer to the vehicle, bending over to the tire, etc.

In a further exemplary embodiment, the vehicle tire valve comprises a signaling element. According to the invention, the signaling element is controlled by the mobile terminal. The signal element can, for example, be a lighting element, for example be an LED. The signal element can be arranged on the vehicle tire valve or in particular in the immediate vicinity, for example on a rim of the tire.

Further according to the invention is a program product for execution on the mobile device. The program product controls a camera on the mobile device. The program product further evaluates the image captured by the camera and displays the valve position in this image. The program product can be designed as a computer program product or an APP for a smartphone, as well as software that is suitable for a smartphone or other device.

Advantageously, the program product is designed to superimpose the marking that the program product created on the recorded image.

The program product can establish a radio connection to the signaling element on the vehicle tire valve.

For example, the program product is set up so that the marking in the recorded image and the signal element light up simultaneously or alternately and thus indicate the position of the valve.

In a further embodiment, the program product can be coupled to a control unit of the vehicle. For example, the control unit is the vehicle's infotainment system or another vehicle control unit that can access data from a tire pressure sensor.

The program product can be started by an input from the user in the mobile device or by a value from the tire pressure sensor.
