Abstract: A method for reducing nitrogen oxide emissions of a diesel vehicle. In this context, first state variables of the diesel vehicle are measured with the aid of sensors of the diesel vehicle, and using an arithmetic unit, it is ascertained, as a function of the first state variables, if the nitrogen oxide emissions are exceeding a predetermined threshold, or using the arithmetic unit, it is predicted, as a function of the first state variables, if the nitrogen oxide emissions will exceed the predetermined threshold. If exceedance of the threshold is calculated or predicted, then an intervention in the current torque demand of the diesel vehicle and/or an intervention in the current transmission ratio or setting of a transmission of the diesel vehicle is ascertained by the arithmetic unit; the intervention contributing to a reduction in the nitrogen oxide emissions to a value below the threshold.

Abstract: A method is provided for monitoring at least one sensor of a vehicle, which has means for wireless communication, wherein measured values of the at least one sensor are compared to measured values of at least one comparison vehicle with the aid of the means for wireless communication.

Abstract: A method for querying vehicle data, e.g., data related to the odometer reading and/or wear of the vehicle, includes the following steps: a) transmitting a vehicle identifier from a user terminal to a server; b) establishing a wireless data link between the server and the vehicle identified by the vehicle identifier; c) transmitting data from the control unit of the vehicle to the server; d) analyzing the transmitted data; and e) transmitting the data and/or the analysis results to the user terminal.

Abstract: By detecting the pressure time characteristic on the high-pressure side of an injection pump, the delivery volume of the pump is able to be determined without intervention in the injection system.

Abstract: A method for model-based diagnosis of a mechatronic system. A control unit within the mechatronic system performs error detection and an arithmetic unit outside of the mechatronic system performs error identification.
