    摘要： A method controls an operation of a motor vehicle equipped with a hybrid drive unit having a combustion engine and at least one electric machine that can be selectively operated as a motor or as a generator. The electric machine, when in generator mode, charges an energy store and/or supplies power to a vehicle electrical system of the motor vehicle. In generator mode, the electric machine is operated in alternating intervals, while maintaining predefined boundary conditions. In a first interval, the electric machine is operated with a first high electrical power output that is higher than an actual power consumption of the vehicle electrical system of the motor vehicle. The electric machine is switched off in a second interval. This largely prevents the electric machine from approaching operating points under light load which have a low efficiency and achieves a fuel advantage in comparison to a continuous operating mode.

    摘要： In a method and a device for determining a charge/aging state of an energy store, the charge/aging state is able to be determined by a control unit on the basis of an open terminal voltage of the energy store, able to be measured with the aid of a voltage-measuring sensor, in a load-free state. It is provided that the control unit initiates a measurement of a first open terminal voltage at a first instant following the occurrence of the load-free state of the energy store and, based on the measured first open terminal voltage, the control unit, with the aid of a prediction model, specifies a future instant for at least one additional measurement of the open terminal voltage, and at least one additional open terminal voltage is measured at the future instant, and the charge/aging state of the energy store is determined with the aid of the at least one additional open terminal voltage.

    摘要： A method is for controlling the operation of an exhaust-gas sensor disposed in an exhaust duct of a motor vehicle and equipped with an internal or external sensor heating device, the motor vehicle including a combustion engine and an automatic switchoff, which causes an automatic switching off of the combustion engine when at least one stop condition is present. It is provided that: (a) following an automatic switching off of the combustion engine by the automatic switchoff, a first future instant is determined at which the exhaust-gas temperature in the exhaust duct will drop below a condensation temperature below which condensate precipitation from the exhaust gas may occur; (b) a second instant is determined at which a heat output of the sensor heating device must be interrupted or reduced so that a sensor temperature of the exhaust-gas sensor will have dropped to a maximally allowed sensor temperature no later than the first future instant; and the heat output of the sensor heating device is interrupted or reduced when the second instant is attained.
