Abstract

A vehicle with an internal combustion engine, with a physical onboard power supply system and with at least one electrical energy source, wherein electrical consumers are integrated in the physical onboard power supply system and the physical onboard power supply system comprises a switchable terminal 15, wherein, when the terminal 15 is actuated and the internal combustion engine is switched off or when the internal combustion engine is running at a low rotational speed, each of the electrical consumers is assignable by a control device to either a first group of electrical consumers or a second group of electrical consumers, an electrical consumer of the first group is at least partly able to be switched on and off by a user, an electrical consumer of the second group cannot be switched by the user, and an electrical consumer which is switched on at least partly can be supplied with electrical power from the at least one electrical energy source.

Claims

1. A vehicle with an internal combustion engine, with a physical onboard power supply system and with at least one electrical energy source, wherein electrical consumers are integrated in the physical onboard power supply system, wherein, when the internal combustion engine is switched off or when the internal combustion engine is running at a low rotational speed, each of the electrical consumers is assignable by a control device, on a time-dependent basis, to either a first group of electrical consumers or a second group of electrical consumers, wherein the assignment of an electrical consumer to either of the two groups can be displayed on a display screen to the user of the vehicle, an electrical consumer of the first group is at least partly able to be switched on and off by a user, an electrical consumer of the second group cannot be switched by a user, and an electrical consumer which is switched on at least partly can be supplied with electrical power from the at least one electrical energy source, wherein an energy state of the at least one electrical energy source can be displayed to the user on a time-dependent basis.

2. The vehicle as claimed in claim 1, wherein an energy state of the at least one electrical energy source or of the energy sources can be displayed to the user in the form of a predicted duration at an instant, and the prediction of the duration is based on the power supplied to the at least partly switched-on electrical consumers at that instant.

3. The vehicle as claimed in claim 1, wherein in the event of a critical energy state, the user can be promoted to start the internal combustion engine.
