Abstract

A method is provided for visualizing specified safety-critical information in a vehicle. First display data are (AD_ 1 ) are determined, which are representative of a first image (B 1 ) to be visualized, which provides the specified safety-critical information in a specified first signalization form, the first display data (AD_ 1 ) being determined free of specified safety regulations. The first display data (AD_ 1 ) are sent to a display unit (DISP) of the vehicle and test data (DD) are read out, which are representative of an image visualized on the display unit (DISP). The test data (DD) are checked and, if the test data (DD) are representative of a faulty provision of the specified safety-critical information, second display data (AD_ 2 ) are sent to the display unit (DISP), which are representative of a second image (B 2 ) to the visualized, which provides the specified safety critical information in a specified second signalization form, which differs from the first signalization form. The second display data (AD_ 2 ) are determined while complying with the specified safety regulations.

First claim

What is claimed is:

1. A method for visualizing specified safety-critical information in a vehicle, the method comprising the acts of:
determining first display data representative of a first image to be visualized, said first image providing the specified safety-critical information in a specified first signalization form, wherein the first display data are determined free of any specified safety regulations;
sending the determined first display data to a display unit of the vehicle;
reading-out test data representative of an image visualized on the display unit;
checking if the read-out test data are representative of a faulty provision of the specified safety-critical information; and
if the read-out test data are representative of the faulty provision of the specified safety-critical information, sending second display data to the display unit, which second display data are representative of a second image to be visualized, the second image providing the specified safety-critical information in a specified second signalization form differing from the first signalization form, wherein the second display data are determined while complying with the specified safety regulations.

2. The method according to claim 1 , wherein:
the first display data are determined such that the first image to be visualized comprises validation information, and
the test data are checked via a checking of the validation information.

3. The method according to claim 2 , wherein the test data are cheeked by comparing the test data with specified comparison data.

4. The method according to claim 3 , wherein the specified first signalization form comprises a 3D visualization form, and the specified second signalization form comprises a 2D visualization form.

5. The method according to claim 2 , wherein the specified first signalization form comprises a 3D visualization form, and the specified second signalization form comprises a 2D visualization form.

6. The method according to claim 1 , wherein the specified first signalization form comprises a 3D visualization form, and the specified second signalization form comprises a 2D visualization form.

7. A computer program product, comprising a non-transitory computer readable medium having stored thereon program code segments executed to:
determine first display data representative of a first image to be visualized, said first image providing specified safety-critical information in a specified first signalization form, wherein the first display data are determined free of any specified safety regulations; send the determined first display data to a display unit of a vehicle; read-out test data representative of an image visualized on the display unit; cheek if the read-out test data are representative of a faulty provision of the specified safety-critical information; and
if the read-out test data are representative of the faulty provision of the specified safety-critical information, sending second display data to the display unit, which second display data are representative of a second image to be visualized, the second image providing the specified safety-critical information in a specified second signalization form differing from the first signalization form, wherein the second display data are determined while complying with the specified safety regulations.

8. The computer program product according to claim 7 , wherein the program code segments further:
determine the first display data such that the first image to be visualized comprises validation information, and
check the test data via a checking of the validation information.

9. The computer program product according to claim 7 , wherein the test data are cheeked by comparing the test data with specified comparison data.

10. The computer program product according to claim 7 , wherein the specified first signalization form comprises a 3D visualization form, and the specified second signalization form comprises a 2D visualization form.

11. A vehicle, comprising:
means for visualizing specified safety-critical information in a vehicle, said means comprising a processor and a non-transitory computer readable medium in which program code segments are executed to:
determine first display data representative of a first image to be visualized, said first image providing the specified safety-critical information in a specified first signalization form, wherein the first display data are determined free of any specified safety regulations;
send the determined first display data to a display unit of the vehicle;
read-out test data representative of an image visualized on the display unit;
check if the read-out test data are representative of a faulty provision of the specified safety-critical information; and
if the read-out test data are representative of the faulty provision of the specified safety-critical information, sending second display data to the display unit, which second display data are representative of a second image to be visualized, the second image providing the specified safety-critical information in a specified second signalization form differing from the first signalization form, wherein the second display data are determined while complying with the specified safety regulations.
