Abstract
A method for operating a vehicle having: an internal combustion engine for driving the vehicle; at least one emission-relevant load; at least one electrical-system battery; and at least one vehicle battery, in which method prior to the start-up of the vehicle, the at least one vehicle battery is charged with electrical energy from the at least one electrical-system battery and, prior to and/or during the start-up of the internal combustion engine, the at least one emission-relevant load is charged with this electrical energy from the vehicle battery.
Claims19
A method for operating a vehicle comprising an internal combustion engine for driving the vehicle, at least one emission-relevant load, at least one electrical-system battery, and at least one vehicle battery, the method comprising:
- determining a quantity of electrical energy which was required to start the at least one emission-relevant load during a current or previous n-th journey,
- after determining that the at least one emission-relevant load is to receive a transfer, and prior to the emission-relevant load being supplied with the quantity of electrical energy, transferring the quantity of electrical energy from the at least one electrical-system battery to the at least one vehicle battery prior to an initial start of the vehicle for an upcoming n+1-th journey, and
- energizing the at least one emission-relevant load using the vehicle battery prior to startup of the internal combustion engine for the upcoming n+1-th journey,
- wherein the at least one vehicle battery has an electrical voltage which is higher than that of the at least one electrical-system battery.
A system for operating a vehicle, the vehicle comprising an internal combustion engine for driving, at least one emission-relevant load, at least one electrical-system battery, and at least one vehicle battery, the system comprising at least one control unit which is configured to:
- determine a quantity of electrical energy which was required to start the at least one emission-relevant load during a current or previous n-th journey,
- after determining that the at least one emission-relevant load is to receive a transfer, and prior to the emission-relevant load being supplied with the quantity of electrical energy, command transfer of the quantity of electrical energy from the at least one electrical-system battery to the at least one vehicle battery prior to an initial start of the vehicle for an upcoming n+1-th journey, and
- command energization the at least one emission-relevant load using the vehicle battery prior to startup of the internal combustion engine for the upcoming n+1-th journey,
- wherein the at least one vehicle battery has an electrical voltage which is higher than that of the at least one electrical-system battery.
