The invention relates to a method for measuring the torque of a drive unit (), particularly a vehicle drive unit (), said drive unit () comprising at least one bearing () for connecting to a fixed support point (), and at least one sensor () being provided which measures a change in force and/or position, particularly a relative rotation of the drive unit (), as a sensor value, wherein a torque at the drive unit () is determined as a measurement value on the basis of said sensor value.

Method for measuring torque of a drive unit

The invention relates to a method, to a device, and to a system for determining a position of a vehicle. The method comprises the method steps: Measuring (S) at least one first magnetic field strength of a magnetic field at one each first position (A-i) by means of a first magnetic field sensor () arranged on a vehicle (); measuring (S) at least one second magnetic field strength of the magnetic field at one each second position (B-i) by means of a second magnetic field sensor () arranged on the vehicle () at a distance from the first magnetic field sensor (); determining (S) position data of the vehicle () at least by comparing data, which are based on the measured first and second magnetic field strengths, to a predetermined magnetic field data of the magnetic field; and outputting (S) a signal based on said position data.

Method, device and system for determining a position of a vehicle

A motor vehicle having an internal combustion engine, a differential pressure sensor or two pressure sensors for detecting a pressure difference, which may be in an exhaust tract of the internal combustion engine, and an evaluation unit for evaluating the detected pressure difference. Moreover, the present invention relates to a method for operating a motor vehicle. A controlling arrangement is provided for controlling an automatic start-stop system or an ignition system of the motor vehicle as a function of the result of the evaluation of the detected pressure difference used to detect immersion or submersion of a tailpipe of the exhaust tract in water, sludge, or a similar liquid medium in order to prevent the internal combustion engine from shutting off when the tailpipe is immersed or submerged.

Method for operating a fording-capable motor vehicle, and fording-capable motor vehicle

A method for the fail-safe operation of a hybrid vehicle having an internal combustion engine, an electric motor, and additional vehicle assemblies. A substitute measure that then still allows the vehicle to be operated under emergency running conditions is initiated if a vehicle assembly fails. A performance quantity that is characteristic of the driving-dynamics situation in which the vehicle finds itself is recorded prior to initiating the substitute measure, and is compared to at least one limit value. The substitute measure is initiated if the limit value is exceeded or not attained. A device which includes a device for implementing such a method is also provided.

Method for the fail-safe operation of a hybrid vehicle for the controlled initiation of a substitute measure allowing an operation of the vehicle under emergency conditions, and device for implementing this method

A device and a method for generating a vacuum in a brake system of a vehicle equipped with a hybrid drive. The hybrid drive includes an internal combustion engine and at least one electric drive, which is selectively uncoupled from the internal combustion engine with the aid of a clutch. A vacuum pump having an adjustable pumping capacity is mechanically connected to the at least one electric drive.
