Abstract
A method and a device for improving the restart of a vehicle equipped with start-stop operation. In order to accelerate the restart, in a stop phase of the start-stop operation a control unit provides control signals on the basis of which the excitation winding is supplied with a pre-excitation current in the stop phase. In addition, given the presence of a restart request occurring during the slowdown of the internal combustion engine, the control unit checks whether an immediate restart is possible and sensible, and, in the case in which an immediate restart is possible and sensible, initiates an immediate restart, and delays the restart in the case in which an immediate restart is not possible or not sensible.

A method for improving a restart of a vehicle equipped with start-stop operation, having an excitation winding allocated to the starter generator of the vehicle and having a control unit, the method comprising:
- providing control signals from the control unit to influence the excitation current flowing through the excitation winding, and in which, in a stop phase of the start-stop operation, wherein the control unit provides control signals on the basis of which the excitation winding is supplied with a pre-excitation current in the stop phase;
- and
- given the presence of a restart request occurring during the slowdown of the internal combustion engine, checking, using the control unit, whether an immediate restart is possible and sensible, and if so, initiating an immediate restart, and if not, delaying the restart.
A device for improving a restart of a vehicle equipped with start-stop operation, comprising:
- a starter generator having an excitation winding;
- and
- a control unit connected to the starter generator via a line;
- wherein the control unit is configured for improving the restart of the vehicle equipped with start-stop operation, having the excitation winding allocated to the starter generator of the vehicle and having the control unit, by performing the following:
- providing control signals from the control unit to influence the excitation current flowing through the excitation winding, and in which, in a stop phase of the start-stop operation, wherein the control unit provides control signals on the basis of which the excitation winding is supplied with a pre-excitation current in the stop phase;
- and
- given the presence of a restart request occurring during the slowdown of the internal combustion engine, checking, using the control unit, whether an immediate restart is possible and sensible, and if so, initiating an immediate restart, and if not, delaying the restart.
