- this at least one emission-relevant consumer can be started up with this electrical energy, for example started.
- the at least one emission-relevant consumer is heated or heated with electrical energy from the at least one traction battery until an operating temperature provided for this has been or has been reached.
- the at least one consumer is supplied with electrical energy from the at least one traction battery before the internal combustion engine is started, which is already present before the vehicle is started or started, usually at the end of an immediately preceding operation -th trip from which at least one electrical system battery has been charged into the at least one traction battery. This is possible, for example, if the at least one emission-relevant consumer has a temperature that is lower than the operating temperature intended for it.
- the electrical energy is emitted for a future n + 1-th trip and / or a future start of the vehicle the at least one electrical system battery is loaded into the at least one traction battery.
- the method to charge electrical energy from the on-board electrical system battery into the at least one traction battery before the vehicle is started as a first start, this electrical energy from the at least one traction battery when the vehicle is started for the first time and before an initial start trained start of the internal combustion engine is loaded into the at least one emission-relevant consumer.
- a respective first start is carried out after the vehicle has stopped after the previous nth trip and before the future n + 1th trip.
- the amount of electrical energy required to drive the at least one emission-relevant consumer for the n-th journey and from the at least one traction battery into the at least one emission-relevant consumer for the n- th trip or last charged for it wherein when the internal combustion engine and / or the vehicle is turned off after this nth trip at least this amount of electrical energy for preparing the next immediately following n + 1th trip from the at least one on-board electrical system battery the at least one traction battery is charged. The amount of energy required during the previous nth trip is thus determined.
- the method is carried out for at least one emission-relevant consumer, ie for starting up at least one emission-relevant consumer, which is used as an exhaust gas cleaning device or exhaust system, for example. is designed for exhaust gas aftertreatment for exhaust gas from the internal combustion engine, and / or as an air conditioning module.
- the vehicle for example a motor vehicle or a car, has, in addition to the internal combustion engine, at least one electric machine for driving or moving the vehicle, this electric machine being provided with electrical energy from the vehicle electrical system battery while the vehicle is traveling.
- a vehicle is designed as a flybrid vehicle.

H. before starting or starting, especially first start, e.g. directly before the start of the at least one emission-relevant consumer, for example during a first defined or definable period before starting, during the start of the at least emission-relevant consumer and / or also after starting or start, in particular first start of the at least one emission-relevant consumer, for example during a second defined or definable period of time, after starting, loaded into the at least one emission-relevant consumer.
- a respective time span lasts, for example, several seconds, for example 60 seconds.
- the electrical energy for starting the at least one emission-relevant consumer d. H. before starting or starting, especially first start, e.g. directly before starting the internal combustion engine, e.g. during a first defined or definable period of time before starting, but additionally also during starting of the internal combustion engine and / or also after starting or Start, in particular first start, of the internal combustion engine, for example during a second defined or definable period of time, after starting, loaded into the at least one emission-relevant consumer.
- the system according to the invention is designed to operate a vehicle, the vehicle driving an internal combustion engine or moving the vehicle, has at least one emission-relevant consumer, at least one on-board electrical system battery, for example starter battery, and at least one traction battery.
- the system has at least one control device which is designed to cause electrical energy from the vehicle electrical system battery to be charged into the at least one traction battery before the vehicle is started or started, for example, for the first time, and to have this electrical energy from the at least traction battery, for example when the vehicle is started and before the start or start, for example the first start, of the internal combustion engine is charged into the at least one emission-relevant consumer.
- Secondary air system as an air conditioning module, static in the 48 V battery or traction battery, as the energy required is dynamically stored in the on-board electrical system battery and already when the vehicle is switched off after driving or after a driving cycle before and thus before starting the Combustion engine for the future journey or for a future driving cycle for floch driving the at least one exhaust gas-relevant consumer for this future journey has first been charged from the at least one electrical system battery into the at least one traction battery. It is therefore possible to comply with an emissions standard, e.g. EU7.

- this energy of the at least one traction battery is available before the internal combustion engine starts and the at least one emission-relevant consumer is made available from the at least one traction battery for starting up the internal combustion engine. This energy is not required during an active journey or during an active driving cycle while the vehicle is in operation, since the at least one emission-relevant consumer has already started up and has, for example, its intended operating temperature.
- the necessary energy is stored or stored in the at least one on-board electrical system battery and stored or stored in the at least one on-board electrical system battery until the end of the journey or the driving cycle.
- the electrical energy is transferred from the at least one on-board electrical system battery to the at least one traction battery, the electrical energy from a 12 V side of an on-board electrical system of the vehicle, which has the at least one on-board electrical system battery, is transferred to a 48 V side of the on-board electrical system of the vehicle, which has the at least one traction battery, and therein until a new or future or subsequent start of the vehicle and the startup of the at least one emission-relevant one to be carried out Consumer.
- a respective start-up of the at least one emission-relevant consumer is prepared at the end of the previously carried out journey.
- the power required for the at least one emission-relevant consumer immediately after the start of the internal combustion engine is provided by the at least one traction battery in one embodiment of the method, since this energy cannot be produced in series by a generator.
- a maximum generator power consumption from the internal combustion engine has been u. a. due to acoustics and emissions only possible in the range from 4 kW to 8 kW.
- an electrical output of up to 15 kW can be provided as part of the method.
- the energy for supplying the at least one emission-relevant consumer is already provided by the at least one on-board electrical system battery during the previously carried out journey and is only made available to the at least one traction battery for the next journey at the end of the previously carried out journey.
- the at least one traction battery can provide sufficient energy for a driving strategy provided in each case, but a required C02 saving potential can nevertheless be achieved.
- the method increases the electrical energy for the at least one emission-relevant consumer.
- the required energy is provided, for example, after the vehicle and / or the internal combustion engine of the traction battery has been switched off from the vehicle electrical system battery.
- a defined amount of electrical energy is charged directly from the at least one on-board electrical system battery into the at least one traction battery before the actual journey or an active driving cycle when the method is implemented, directly as a result of the vehicle being switched off.
- the first operating state A provided here is an nth trip of the vehicle 2, n being an integer, it being provided here that functions of the vehicle 2 during the trip also independently of the embodiment of the method presented here, can be controlled by the control unit 6.
