Description

The invention relates to a system for a vehicle for creating a log of a journey of the vehicle, as well as a vehicle with such a system.

In order to reduce accidents with motor vehicles and buses, it is common in such vehicles, and in many countries even legally prescribed, for a tachograph, also called a tachograph, to record the vehicle's movements and / or input on the vehicle and thus log them.

On the tachograph, it is typically noted in the log which person has driven the vehicle. This is usually done using a so-called driver card, which is designed similar to an identity card and has an electronic memory unit on which the personal data of a driver are stored.

The DE 10 2018 000 486 A1 In this context, relates to a method for logging the driving and rest times of a driver of an autonomously driving motor vehicle in a tachograph, wherein a driving operating state, in particular a state of an autonomous driving operation of the motor vehicle, is detected, a state of the driver's readiness to take over is detected, whereby a A period of time is logged depending on the driving mode and the readiness to take over status.

The object of the invention is to carry out a technical adaptation of a system with a tachograph in order to take account of the increasing automation in vehicles.

The invention results from the features of the independent claims. Advantageous further developments and refinements are the subject matter of the dependent claims.

A first aspect of the invention relates to a system for a vehicle, in particular for a truck or a bus, for creating a log of a journey of the vehicle, having a tachograph that has a first interface for a first physical driver card and a second interface for a second physical driver card or to a second virtual driver card, the first driver card being assigned to a human driver, and the second driver card being assigned to an automatic driving control device of the vehicle, the tachograph for logging driving movements of the vehicle and driving inputs on the vehicle, assigning the driving inputs to the human driver or to the automatic driving control device based on the respective driver card.

The vehicle is in particular a truck for transporting goods or a bus for transporting people. Operation of a tachograph is typically required in such types of vehicles.

The tachograph is a unit typically installed in the vehicle that logs the vehicle's movements and inputs. These data, such as the speed of the vehicle, brake actuation, kilometers driven and other data, have a respective time stamp so that at the end of the journey it can be traced what state the vehicle assumed during the journey and, for example, whether the brakes were sharp. Such data can then typically be read out from a storage unit of the tachograph and archived, or used for control by the executive. That is why the tachograph is often referred to colloquially as a tachograph or black box.

If the vehicle is operated in the purely manual mode, the personal data (at least an identification number) of the human driver is transmitted to the tachograph, and the log for the manually executed trip is made with assignment to the human driver. This is evident from the protocol.

If there is an intervention in the control of the vehicle by means of a driving input by the automatic driving control device, or a related automated driving maneuver, or an entire automated driving section, or the entire driving is carried out automatically by the automatic driving control, this would also be wrongly passed on to the human driver be assigned.

For this purpose, according to the invention, the tachograph has a second interface at which a second physical driver card can be arranged or which can be connected to a second virtual driver card.

It is therefore an advantageous effect of the invention that a driving input (and in particular also a driving movement of the vehicle) made by the automatic driving control device is not assigned to the human driver but to the automatic driving control device in the log. This can, for example, relieve the human driver if the automatic driving control device commits a traffic violation. Furthermore, it can be prevented that a driver of the vehicle can manually drive the vehicle with the claim that the automatic drive control device has completed the drive. Furthermore, the log can advantageously be analyzed by the operator during an automatic drive of the automatic drive control device between transport nodes, or used as evidence for the use of an upgrade kit for the vehicle, or used to use different "virtual drivers" on the automatic drive control device when booking as a service become.

According to an advantageous embodiment, the automatic driving control device is designed to make a driving input of the vehicle only when the second driver card is connected to the second interface. In this way, it can advantageously be ensured in the log that all driving inputs assigned to the human driver have also been carried out by the human driver.

According to a further advantageous embodiment, the second driver card is a physical driver card, the tachograph having an insertion device with the second interface. Analogous to the first driver card, which is preferably inserted into the tachograph like a card reader, a physical card can also be provided for the automatic driving control device. This advantageously facilitates the operation for the human driver, since the concept of physical cards is only expanded to include one additional card.

According to a further advantageous embodiment, the second driver card is a virtual driver card, data from the virtual driver card being stored in a memory unit of the tachograph and the virtual driver card being implemented in the tachograph. The second driver card is implemented directly in the tachograph itself and can be activated if necessary.

According to a further advantageous embodiment, the second driver card is a virtual driver card, the virtual driver card being stored and implemented in a computing unit of the automatic driving control device connected to the tachograph. This computing unit of the automatic driving control device is connected to the tachograph, so that the second driver card can advantageously be activated on the tachograph.

According to a further advantageous embodiment, the second driver card is a virtual driver card, the virtual driver card being stored and implemented on a central processing unit or on a mobile terminal of a user, in particular the human driver. Here, too, the second driver card only has to be activated, the central processing unit being in particular a server with which the vehicle is connected in terms of data technology. The user's mobile device can be connected to the tachograph via Bluetooth, for example.

According to a further advantageous embodiment, the tachograph has a display unit, in particular a screen, the display unit being designed to display whether a driving movement of the vehicle and / or a driving input on the vehicle is currently assigned to the human driver or the automatic driving control device in the log. While driving the vehicle, the human driver can advantageously always see whether the data currently written on the tachograph are assigned to him or to the automatic driving control device.

According to a further advantageous embodiment, the tachograph is designed to store the log of the journey in the tachograph.

According to a further advantageous embodiment, the tachograph is designed to store the log of the journey on the first driver card and / or on the second driver card.

Another aspect of the invention relates to a vehicle with a system as described above and below.
