1. A motor vehicle comprising:
- wheels;
a vehicle drive;
a brake device;
a vehicle component which heats up when the vehicle drive and/or the brake device are operated;
a warning indicator to output first visual warning information when a vehicle component-specific limiting temperature is exceeded by the vehicle component; and
a light source disposed at the vehicle component to at least partially illuminate the vehicle component to output second visual warning information, when the limiting temperature is exceeded by the vehicle component and/or when the vehicle component receives an information item which relates to the limiting temperature being exceeded, and only when a predetermined compartment of the motor vehicle is opened or when the motor vehicle is stationary, and is prevented from illuminating the vehicle component when the motor vehicle is not stationary; and
a controller configured;
to determine, based on a rotational speed of the wheels, whether the motor vehicle is stationary, andto prevent the light source from illuminating the vehicle component, independently of whether the predetermined compartment of the motor vehicle is opened or closed, when the controller determines, based on the rotational speed of the wheels, the motor vehicle is not stationary, even when the limiting temperature is exceeded by the vehicle component,whereinthe warning indicator includes a material applied to the vehicle component which changes color characteristics to output the first visual warning information, when the limiting temperature is exceeded, and the material comprises a predetermined three-dimensional surface patterning to improve visual perceptibility when the limiting temperature is exceeded.

Abstract
A motor vehicle has at least one drive unit, at least one brake device and at least one component which heats up when the drive unit and/or the brake device are operated. The component includes at least one warning device which is designed to output a visual warning information item when a component-specific limiting temperature is exceeded by the component, and/or can be actuated to output a visual warning information item when an information item which relates to a component-specific limiting temperature being exceeded is present.

15. A motor vehicle comprising:
-
wheels; a vehicle drive; a brake device; a vehicle component which heats up when the vehicle drive and/or the brake device are operated; a warning indicator to output visual warning information when a vehicle component-specific limiting temperature is exceeded by the vehicle component, and/or when the vehicle component receives an information item which relates to the limiting temperature being exceeded, wherein the warning indicator includes a light source disposed at the vehicle component to at least partially illuminate the vehicle component to output the visual warning information, when the limiting temperature is exceeded and/or when the vehicle component receives the information item which relates to the limiting temperature being exceeded, and only when a predetermined compartment of the motor vehicle is opened or when the motor vehicle is stationary, and is prevented from illuminating the vehicle component when the motor vehicle is not stationary; and a controller to control activation of the light source based on a rotational speed of the wheels, wherein the brake device is disposed at at least one of the wheels, the light source is configured to at least partially illuminate the brake device when the limiting temperature is exceeded by the vehicle component and only when the motor vehicle is stationary, and the controller prevents the light source from illuminating the brake device when the motor vehicle is not stationary. - View Dependent Claims (16, 17, 19, 20, 21, 22, 26)

23. A motor vehicle comprising:
-
a vehicle drive; a brake device; a vehicle component which heats up when the vehicle drive and/or the brake device are operated; a warning indicator including; a material coupled to the vehicle component and a light source to output visual warning information when a vehicle component-specific limiting temperature is exceeded by the vehicle component, and an electronic audio output device configured to output audible warning information when the limiting temperature is exceeded by the vehicle component and only when the motor vehicle is stationary; and a controller configured; to control activation of the light source so that the vehicle component is at least partially illuminated by the light source when the limiting temperature is exceeded by the vehicle component and only when a predetermined compartment of the motor vehicle is opened or when the motor vehicle is stationary, to prevent the light source from illuminating the vehicle component when the motor vehicle is not stationary, and to prevent the electronic audio output device from outputting the audible warning information when the limiting temperature is exceeded and the motor vehicle is not stationary wherein chemical properties of the material temporarily change in response to a change in temperature of the material, when the limiting temperature is exceeded, transmission characteristics of the material change so that the material is substantially transparent, thereby revealing a warning layer of color provided on the vehicle component beneath the material, and the controller varies a color intensity output by the light source as a function of the temperature of the vehicle component such that the color intensity output by the light source is gradually reduced during cooling of the vehicle component. - View Dependent Claims (24, 25)
