Device for improving the visibility conditions in a motor vehicle
First Claim
1. A device for improving the visibility conditions in a motor vehicle, having a radiation source for infrared radiation for irradiating the surroundings of the vehicle, an infrared-sensitive camera for taking images of at least part of the irradiated surroundings, a display unit for displaying collected image data, and a control unit for controlling the device, wherein an image evaluation unit is provided which is connected to the camera and the control unit and which evaluates the sensed image data with respect to the recommended maximum velocity Vmax, and wherein the control unit is designed in such a way that when a vehicle velocity v exceeds the maximum velocity vmax the display is switched off.

Abstract
The invention relates to a device for improving the visibility conditions in a motor vehicle, having a radiation source for infrared radiation for irradiating the surroundings of the vehicle, having an infrared-sensitive camera for taking images of at least part of the irradiated surroundings, having a display unit for displaying collected image data, and having a control unit for controlling the device. Furthermore, an image evaluation unit is provided which is connected to the camera and the control unit and which evaluates the sensed image data with respect to the recommended maximum velocity Vmax. A velocity sensor which is connected to the control unit is provided in such a way that the control unit causes the display to be switched off when the vehicle velocity v exceeds the maximum velocity vmax. The display is preferably switched on when the vehicle velocity v drops below the maximum velocity vmax. This device ensures that the vehicle with the device operates in a safe way for the user.
