Warning unit in a vehicle for warning the driver when there is an imminent danger

1. A warning unit in a vehicle for warning a driver of an imminent danger, comprising:

a control unit configured to detect the imminent danger based on signals from a plurality of sensors of the vehicle and/or from a different vehicle via vehicle-to-vehicle communication and provide a driver message when the imminent danger is detected in surroundings of the vehicle;

an actuator system configured to output the driver message, wherein

when the imminent danger is detected in the surroundings of the vehicle, the control unit generates a first signal based on the detection of the imminent danger and the actuator system outputs a flow of air in a direction of the driver and the control unit generates a second signal based on the detection of the imminent danger and the actuator system sets the flow of air that is output in the direction of the driver to a predefined temperature, and wherein the predefined temperature is selected based on the imminent danger.

2. The warning unit according to claim 1 , wherein the actuator system is part of an air-conditioning system of the vehicle, the air-conditioning system comprising a neck air-conditioning unit having air vent openings in an upper region of a vehicle seat.

3. The warning unit according to claim 2 , wherein the air vent openings are arranged in a head rest of the vehicle seat.

4. The warning unit according to claim 1 , wherein the control unit outputs the signal that brings about the flow of air in the direction of a neck of the driver.

5. The warning unit according to claim 1 , wherein the flow of air in the direction of the driver is variably predefined as a function of a position of the imminent danger.

6. The warning unit according to claim 1 , wherein the predefined temperature is a function of defined parameters.

7. The warning unit according to claim 1 , wherein the flow of air in the direction of the driver has a predefined intensity, the predefined intensity of the flow of air being variable as a function of defined parameters.

8. The warning unit according to claim 1 , wherein

the control unit outputs the signal that brings about the flow of air in the direction of the driver in response to a signal of a driver assistance system that detects imminent danger in the surroundings of the vehicle, and

the driver assistance system is a blind spot driver assistance system.

9. A method of warning a driver in a vehicle of an imminent danger, the method comprising the acts of:

detecting, by a control unit, an imminent danger in surroundings of the vehicle based on signals from a plurality of sensors of the vehicle and/or from a different vehicle via vehicle-to-vehicle communication;

generating, by the control unit, a first signal based on the detection of the imminent danger and providing the first signal to an actuator system of the vehicle and generating a flow of air in a direction of the driver by the actuator system based on the first signal; and

generating, by the control unit, a second signal based on the detection of the imminent danger and providing the second signal to the actuator system of the vehicle and setting the flow of air that is generated in the direction of the driver to a predefined temperature based on the second signal, and

wherein the predefined temperature is selected based on the imminent danger.

10. The method according to claim 9 , wherein the imminent danger is an object located in a blind spot of the vehicle.

11. The method according to claim 9 , wherein the act of generating the flow of air further comprises directing the flow of air onto a neck region of the driver.

12. The method according to claim 11 , wherein the act of directing the flow of air onto the neck region of the driver is carried out by directing the flow of air onto a left-hand side or a right-hand side of the neck region of the driver based on a location of the imminent danger.

13. The warning unit according to claim 1 , wherein the predefined temperature is based on one or more of the following: (i) a type of the imminent danger, (ii) a position of the imminent danger, (iii) a potential consequence of the imminent danger, and (iv) a passenger compartment air-conditioning parameter.
