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, a sensing unit for a recommended maximum velocity vmax is provided and is connected to the control unit. 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.
