Abstract: 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.

Abstract: A method is described for generating a tactile driver feedback regarding the operational readiness of a vehicle, in particular a hybrid vehicle, the feedback being generated as a function of the state of a drive train of the vehicle.

Abstract: A method for operating a vehicle having a hybrid drive, which vehicle is driven by a first drive unit implemented as internal combustion engine, and a second drive unit, which may be an electric motor, the first drive unit and the second drive unit contributing to the drive of the vehicle individually or jointly. In a method for operating a vehicle having a hybrid drive, in which the driver is informed about the connection of the different drive units, haptic feedback is provided to the driver when the previously idle drive unit is connected to the drive unit that is in operation.

Abstract: In a method for informing a driver of a vehicle about a capability of an electric motor in the vehicle to output a minimum power able to be requested by the driver, a variable display of a display element is implemented depending upon whether the requestable minimum power is able to be provided by the electric motor over a specifiable period of time.

Abstract: A method for operating a hybrid vehicle, which has a first and a second drive unit, in which the second drive unit is started by at least a portion of the operating energy generated by the first drive unit. In order to improve the driving comfort of the hybrid vehicle during the startup of the second drive unit while driving, the second drive unit, which is at rest, is started using kinetic energy obtained from a driving movement of the hybrid vehicle, while the hybrid vehicle is driven by the first drive unit.
