Method for operating a motor vehicle, and motor vehicle
A method for operating a motor vehicle, in particular a passenger car, wherein the motor vehicle has a communication apparatus for receiving traffic light information transmitted from a traffic light and relating to the traffic light control of the traffic light, and a vehicle light arrangement having at least one vehicle light and assigned to the rear or the front or the sides of the vehicle. Each vehicle light is used to implement an operating light function relating to the operation of the motor vehicle. The at least one piece of the traffic light information and/or derived information that is derived therefrom and is independent of the motor vehicle is displayed to another road user by means of the vehicle light arrangement. The at least an activation and/or deactivation of the display of the at least one piece of information only takes place together with a change with respect to at least one of the at least one operating light function and/or when the motor vehicle is stationary.
1 . A method for operating a motor vehicle, the method comprising:
receiving, by a communication apparatus, from a traffic light, traffic light information, the traffic light information being related to traffic light control of the traffic light;
implementing, by a vehicle light arrangement, at least one operating light function relating to an operation of the motor vehicle, the vehicle light arrangement being assigned to a rear, a front, or a side of the motor vehicle, wherein the vehicle light arrangement comprises at least one vehicle light; and
displaying, by the vehicle light arrangement, to another road user, at least one piece of the traffic light information and/or derived information, the derived information being derived from the traffic light information and being independent of the motor vehicle,
wherein an activation and/or a deactivation of the displaying the at least one piece of the traffic light information occurs only in conjunction with a change to the at least one operating light function.
2 . The method of claim 1 , further comprising communicating with the traffic light according to a vehicle-to-vehicle communication standard.
3 . The method claim 1 , further comprising controlling a first portion of lighting segments of the vehicle light arrangement to output the at least one piece of the traffic light information, wherein each of the lighting segments is independently controllable.
4 . The method of claim 3 , wherein the implementing the at least one operating light function includes using a second portion of the lighting segments, the second portion not overlapping with the first portion, and the second portion being completely encompassed by the at least one vehicle light assigned to the at least one operating light function.
5 . The method of claim 4 , further comprising controlling the second portion of the lighting segments to fulfill at least one light value requirement for the at least one operating light function.
6 . The method of claim 3 , further comprising using the lighting segments of the at least one vehicle light, and/or a dedicated display apparatus that is assigned a task of displaying the at least piece of the traffic light information, and/or projection segments of a projection apparatus as the first portion of the lighting segments.
7 . The method of claim 3 , wherein the lighting segments are at least partially formed by organic light emitting diode (OLED) segments.
8 . The method of claim 1 , wherein the at least one operating light function is a direction indicator function, and/or a taillight function, and/or a position light function, and/or a daytime running light function, and/or a brake light function.
9 . The method of claim 1 , wherein a period of time up to a green light and/or an ideal speed permitting a green wave is the at least one piece of the traffic light information.
10 . The method of claim 9 , further comprising displaying the period of time as a countdown.
11 . The method of claim 1 , wherein the displaying the at least one piece of the traffic light information includes using a color used for the operating light function.
12 . The method of claim 1 , wherein the displaying the at least one piece of the traffic light information and/or the derived information includes also displaying, to a driver, using at least partially a human-machine interface in an interior of the motor vehicle.
13 . The method of claim 1 , wherein the displaying being activated and/or being deactivated in conjunction with the change to the at least one operating light function, is also in conjunction with the motor vehicle being stationary.
14 . A motor vehicle comprising:
a communication apparatus configured to receive traffic light information transmitted from a traffic light, the traffic light information being related to traffic light control of the traffic light;
a vehicle light arrangement comprising at least one vehicle light, the vehicle light arrangement being assigned to a rear, a front, or a side of the motor vehicle, wherein the vehicle light arrangement is configured to implement at least one operating light function related to an operation of the motor vehicle; and
a control apparatus configured to actuate the vehicle light arrangement to:
display, by the vehicle light arrangement, to another road user, at least one piece of the traffic light information and/or derived information, the derived information being derived from the traffic light information and being independent of the motor vehicle,
wherein an activation and/or a deactivation of the display of the at least one piece of the traffic light information occurs only in conjunction with a change to the at least one operating light function.
15 . The method of claim 9 , further comprising displaying the period of time in the form of a progress indicator, wherein the progress indicator is an inverted progress indicator.
