Abstract
A method for controlling consumers of a low-voltage on-board electrical system of a motor vehicle reduces, when it is identified that a high-current consumer is connected, the current consumption of another consumer by an amount that corresponds to the current consumption of the high-current consumer. A control apparatus for controlling consumers of a low-voltage on-board electrical system of a motor vehicle is also provided.
Claims7
A method for controlling a consumer of a low-voltage on-board electrical system of a motor vehicle, the method comprising:
- providing a high-current consumer of the low-voltage on-board electrical system, and providing a further consumer of the low-voltage on-board electrical system;
- and
- reducing a current consumption of the further consumer by an amount that corresponds to a current consumption of the high-current consumer, when it is identified that the high-current consumer is connected, wherein the further consumer, whose current value is reduced, is a PWM cooling fan, wherein the PWM cooling fan is driven in a differentiated manner by a pulse width modulation such that a current consumption is adjustable.
A control configuration for a motor vehicle, comprising:
- a control apparatus configured to identify that a high-current consumer of a low-voltage on-board electrical system is connected;
- and
- said control apparatus being configured to reduce a current consumption of a further consumer of the low-voltage on-board electrical system by an amount that corresponds to a current consumption of the high-current consumer, when said control apparatus identifies that the high-current consumer is connected and said control apparatus being configured to evaluate a control signal that indicates a critical load on the low-voltage on-board electrical system and to reduce the current consumption of the further consumer if the control signal indicates a critical load on the low-voltage on-board electrical system.
A method for controlling a consumer of a low-voltage on-board electrical system of a motor vehicle, the method comprising:
- providing a high-current consumer of the low-voltage on-board electrical system, and providing a further consumer of the low-voltage on-board electrical system, wherein the further consumer has an inductance such that an induction voltage is generated when a current value of the further consumer is reduced, wherein the induction voltage additionally feeds the low-voltage on-board electrical system;
- and
- reducing a current consumption of the further consumer by an amount that corresponds to a current consumption of the high-current consumer, when it is identified that the high-current consumer is connected.
A method for controlling a consumer of a low-voltage on-board electrical system of a motor vehicle, the method comprising:
- providing a high-current consumer of the low-voltage on-board electrical system, and providing a further consumer of the low-voltage on-board electrical system;
- evaluating a control signal that provides information about a connection of the high-current consumer;
- and
- reducing a current consumption of the further consumer by an amount that corresponds to a current consumption of the high-current consumer, when it is identified that the high-current consumer is connected.
