Using the microcontroller 72 or the electronic circuit 72 can, for example, in particular data, for example that from the third control unit 48 transferred data, are processed.
  • Furthermore, the first control device 44 in this advantageous embodiment, a first memory 74 with data for a brightness correction, the second control device 46 a second memory 76 with data for brightness correction. The brightness correction of the respective light source or the respective lighting elements of the corresponding light source can in particular be corrected by means of the brightness correction.
  • The third control unit 48 can be in a further development especially as a control unit 48 be designed to control highly automated driving of a vehicle. This allows the first light source 30th and / or the second light source 32 be controllable as a function of a vehicle state of a vehicle ascertained by a sensor or a switch, a state of a vehicle mode, in particular a state of an autonomous vehicle mode, being ascertainable by means of the one or more sensors and / or the switch.
  • Control in an autonomous vehicle can be taken over by the vehicle itself, for example. This can be referred to as HAD, for example, where HAD can also be referred to as Highly Autonomous Driving or as HAF, where HAF can also be referred to as highly automated driving. The functions of automated driving, e.g. traffic jam pilot (TJP) and highway pilot (Highway Pilot, HWP) or others, have different characteristics and can be used in different situations, for example. The functions can be activated, for example, when certain conditions, in particular in the vehicle or in the surroundings of the vehicle, are met. These conditions can be checked in particular by the corresponding HAD function. If one of the conditions is not met, you cannot switch to HAD mode or autonomous driving mode and the driver must therefore continue to drive manually. Prerequisites for activating the traffic jam pilot are, for example, driving on a freeway or a multi-lane highway with a structural separation between the directions of travel, slow-moving traffic up to 60 km / h or traffic jams and / or driving in one's own lane, for example on the freeway. In addition to these prerequisites, other factors can also prevent the HAD function from being activated, such as bad weather conditions such as heavy rain, snow, fog, missing or bad road markings, excessive driving, dirty sensors and / or other influencing factors. For these reasons, it can happen that a highly automated journey over an entire distance from the start to the destination has to be interrupted, which means that the driver has to take over manual driving, for example. Depending on the route, the driver can preferably be repeatedly asked to take control of the vehicle. For this purpose, particularly easy, understandable, manageable and transparent transfers of vehicle guidance from the driver to the vehicle and from the vehicle back to the driver should be made possible for the driver. For this purpose, a communication interface, for example in the form of a visual display and / or an acoustic interaction and / or a haptic interaction, for example a slight braking intervention and / or a manual button, should preferably be between the driver and the vehicle, for example as a suitable human machine Interface or HMI or an operating and display interface. The driver should use the communication interface or the display to convey the state in which a vehicle is, for example in the automated driving mode or in the manual driving mode. Furthermore, a driver should be informed in good time when he has to take over manual vehicle control again in the case of highly automated driving. For this purpose, a driver should in particular be provided with a sufficient period of time, for example about 5 seconds to 20 seconds, in particular about 10 seconds. Even with a critical system error, such as a short circuit in a line or a short circuit in the battery of the vehicle electrical system, the vehicle should be automatically transferred to a safe system state in accordance with IS026262, in particular without the driver having to intervene. Furthermore, it can be made possible, for example, for the driver to be able to intervene in the event of a vehicle error or a system error in accordance with IS026262, for example to cancel an emergency maneuver initiated by the system, for example to bring the vehicle to a stop at the edge of the road or to manually objects during an emergency maneuver to be able to drive around.
  • The functionality of the HMI for signaling the vehicle status and for transferring the driving task between the driver and the vehicle should therefore meet defined functional safety requirements. For example, such functionalities can be used, for example, as ASIL requirements in the range from ASIL C to ASIL D according to the ISO standard ISO 26262 be trained where ASIL can also be called the Automotive Safety Integrity Level.
  • The proposed information system 22 can be designed, for example, to display a current driving mode of a vehicle, in particular a motor vehicle, for example an electric vehicle, a hybrid vehicle, an internal combustion vehicle, which is set up in particular for autonomous driving.
  • By means of the information system 22 The driver can be shown in which system state the vehicle is in terms of the automated driving function. By dividing the task into three control units, for example with different complexity, a high level of functional safety in the visual display and / or acoustic information for the driver can be achieved.
  • The second control unit 46 can be implemented in a further embodiment in vehicles without HAD function and thus vehicles without the function of autonomous driving, in particular as a simple forwarding or omitted. This can save additional costs, for example.
  • The information system 22 is set up to visually inform a viewer or a driver, in particular, of the status of the vehicle with regard to the HAD function. On the one hand, a viewer or a driver can be informed that the HAD function is active or inactive, but that activation is possible or is inactive, but that activation is not possible or is active, the HAD function not in a nutshell more will be available and therefore a manual takeover of the driver is necessary. An important information channel for a person is in particular visual perception, as a result of which a visual presentation or presentation of information is preferably used in the vehicle. The information system in particular can be used for this 22 or the display unit 24th or in particular the first light source 30th and / or the second light source 32 be used.

The two control units are in a further advantageous embodiment 44 , 46 With their own loudspeakers or audio amplifier systems connected to them, they are also able to tell the driver the current driving mode from the third control unit 48 to be transmitted in acoustic form.
  • The first light source 30th and the second light source 32 can transmit information to a driver, for example, by backlighting certain symbols on the vehicle, for example. Alternatively or additionally, a border of a display can also be illuminated. For example, the lighting elements of the light sources can shine in different colors or with different brightness or with alternating brightness over time, for example as flashing lighting.
  • Since the third control unit can also fail in the event of an on-board electrical system failure, it can emit a signal continuously, for example every 100 ms. for example a life signal, to the first control unit 44 and / or the second control device 46 send. As soon as the third control device no longer sends this signal or the life signal, the first control device can 44 and / or the second control device 46 independently generate a signal for the driver that prompts him to immediately start driving. You can also use the first control unit 44 and / or the second control device 46 increase the brightness of the lighting elements of the respective light sources, since it is possible or because of this also the first control device 44 and / or the second control device 46 might have failed. In particular, the respective control unit that shares the power supply with the third control unit fails.
