A method for the diagnosis and/or configuration of a vehicle includes sending, by a back end unit via an air interface to a vehicle unit, a data packet which comprises an order for the diagnosis and/or configuration of the vehicle, evaluating, by the vehicle unit, whether the diagnosis and/or a configuration of the vehicle is to be undertaken, and initiating, by the vehicle unit, the diagnosis and/or a configuration of the vehicle.

Method and system for the diagnosis or configuration of a vehicle

A method for providing at least one specific vehicle state of a vehicle. The method includes acquiring basic parameters of the vehicle from at least one data source; comparing the acquired basic parameters with a comparison list; and providing a specific vehicle state for the acquired basic parameters based on the comparison.

Method for providing at least one specific vehicle state of a vehicle

The high pressure pump includes a drive shaft with at least one cam or eccentric and at least one pump element with a pump piston driven in the reciprocating direction by the cam or eccentric on the driveshaft in a reciprocating motion. A support element is arranged between the pump piston and the cam or eccentric on the driveshaft and also a roller running on the cam or eccentric is mounted to rotate therein. A support for the roller in the direction of rotation is arranged adjacent to the same in the direction of the rotational axis of the roller. The roller and/or the support include a surface with high wear resistance at least in the contact region between the roller and the support.

High pressure pump, in particular for a fuel injection system of an internal combustion engine

A high-pressure pump having a rotationally driven drive shaft with a shaft portion embodied eccentrically to its axis of rotation, on which shaft portion a ring is rotatably supported. At least one pump element, has a pump piston, driven at least indirectly in a reciprocating motion by the drive shaft via the ring and resting at least indirectly on the ring. The ring is provided, at least on its outer face facing away from the shaft portion, with a coating of a friction-reducing paint in at least one region, in which the at least one pump piston rests at least indirectly on the ring.

High-pressure pump for a fuel-injection device of an internal combustion engine

A high-pressure pump having a drive shaft and at least one pump element including a pump piston driven in a reciprocating motion by the drive shaft. A ring on which the pump piston is braced via a support element is rotatably supported on a portion of the drive shaft that is disposed eccentrically to its pivot axis. The ring and/or the support element, at least in their contact region, has many microscopic indentations, and a solid lubricant film is applied to the ring and/or to the support element, at least in their contact region.
