Abstract: A method ascertains a drive clearance after a software update for a set of controllers of a vehicle. The method includes determining a first deviation between the first target state and the first actual state of the software updated. If the first deviation indicates, then a second deviation between the second target state of the set of second target states and the second actual state of the set of second actual states for a first controller is determined. The first controller is linked to a class from a specified controller classification, and one or more properties of controllers are linked to each class of the specified controller classes. If a second deviation indicates, and if a property of the ascertained class of the first controller indicates that the first controller can be downgraded, then the first controller is downgraded after the software update.

Abstract: A method for documenting an update of software of a component of a vehicle includes receiving in a backend a request message transmitted by the vehicle, the request message comprising system parameters of the vehicle. In response to the request message, a check is carried out at the backend using the system parameters in order to determine whether an update of the software of the component is required and, if so, transmitting an update message by the backend to the vehicle. The update message includes at least one text module which in each case describes a change relating to existing software of the component. A respective text module is assigned in each case to a component. In response to the update message, the at least one text module is provided on an output unit assigned to the vehicle.

Abstract: A method and a device for processing a software update for at least one vehicle device, in particular for a head unit in the vehicle. The software update is stored by a control device in a second memory area which is different from a first memory area that has a software currently used by the vehicle device. The control device controls the access of the vehicle device to a single data memory, the data memory including at least the first and second memory areas.

Abstract: A method and an apparatus for updating software for operating vehicle equipment are provided. The apparatus includes a control unit, having a first data store, and multiple pieces of vehicle equipment, each having a further data store, wherein the control unit is configured for storing a first segment of segmented updated software for operating a piece of vehicle equipment in the first data store, and for storing at least one part of the first segment in a second data store of a first piece of vehicle equipment of multiple pieces of vehicle equipment by shifting or copying from the first data store into the second data store.

Abstract: A method and a central data processing device updates software in a plurality of vehicles of a vehicle fleet during a software rollout. Vehicles of the vehicle fleet are registered in a central data processing device by transmitting vehicle identification data of the vehicles to the central data processing device via an air interface when a vehicle connects to the central data processing device for the first time. Additionally, a check is continuously carried out in order to determine whether a trigger signal is present that is suitable for initiating an update of the software in at least one of the plurality of vehicles of the vehicle fleet. At least one vehicle registered in the central data processing device is selected from the plurality of vehicles in the vehicle fleet using the vehicle identification data transmitted to the central data processing device when a trigger signal is ascertained and a software update is available.

Abstract: A device for switching a mode of a vehicle is provided. The device includes a connector that is configured to interface with an on-board diagnostic system of the vehicle; a switch that is configured to indicate a transport mode or an application mode; a memory; and a processor coupled to the memory. The processor includes determination logic that determines the mode of the vehicle based on a state of the switch; and activation logic that activates the mode of the vehicle by sending a first message to the vehicle according to a first protocol, and sending a second message to the vehicle according to a second protocol.
