Abstract

A system for prompting a control unit in a transport device has a power supply circuit for changing the control unit from a normal operational state to a sleep mode. A prompting device is operable to switch the power supply through in order to change the control unit into the normal operational state. The prompting device is not supplied with current in the sleep modes and has a dischargeable energy accumulator. When the prompting device is operated, the energy of the energy accumulator is used to change the control unit into the normal operational states; as a result of the energy of the energy accumulator a switch is operable to connect the control unit to the power supply.

8. A system for prompting a control unit in a vehicle having a power supply circuit for changing the control unit from a normal operational state to a sleep mode, and a prompting device which is operable to switch the power supply through in order to change the control unit into the normal operational state;

wherein,

the prompting device is supplied with substantially no current in the sleep mode and has a dischargeable energy accumulator;

when the prompting device is operated, energy of the energy accumulator is used to change the control unit into the normal operational state;

as a result of the energy of the energy accumulator, a switch is operable to connect the control unit to a power supply; and

the energy accumulator can be charged in the normal operational state, or mechanical energy can be converted to electric power when the prompting device is operated.
