In a method for actuating a starting device for an internal combustion engine, for the case in which the rotational speed of the toothed ring is below a limit value, first a stroke armature in a starter relay is moved and an electric starter motor is switched on after the starter pinion has engaged. If the rotational speed of the toothed ring exceeds the limit value, the starter motor is switched on before the starter pinion contacts the toothed ring.

Method for actuating a starting device for an internal combustion engine

In a method of a start-stop control for an internal combustion engine including briefly stopping and starting the internal combustion engine using an electric machine as a starter, the internal combustion engine is switched off by an engine control when switch-off conditions obtain, and the start-stop control queries whether a start signal exists on the basis of switch-on conditions. In order to ensure that a restart of the internal combustion engine is able to be performed more quickly, the start-stop control acts on the internal combustion engine using an operating strategy within a time period t until the internal combustion engine comes to a standstill.

Method and device of a start-stop control for an internal combustion engine

A method for meshing a starting pinion of a starter device with a toothed ring of an internal combustion engine includes aligning rotational speed of the starting pinion with the rotational speed of the toothed ring before meshing takes place. As meshing occurs, a vibration characteristic is measured. If a vibration characteristic variable is not within an admissible value range, activation of the starting pinion is varied during a subsequent meshing process.

Method for meshing a starting pinion of a starter device with a toothed ring of an internal combustion engine

A device for starting an internal combustion engine of a motor vehicle includes a starter motor having an actuator for engaging a pinion, drivable by the starter motor, with a ring gear, and a control unit which activates a switching output stage associated with the actuator and a switching output stage associated with the starter motor. The starting time of the internal combustion engine is substantially reduced by providing the starter device with a control unit.

Starter device for an internal combustion engine having separate engaging process and starting process

A starting motor for an internal combustion engine, where a control circuit monitors or controls the temperature of the starting motor or the carbon brushes, and if necessary, limits or switches off the primary current. The temperature is indirectly determined by means of a comparison, using the voltage ripple in the primary circuit between the battery and the starting motor. Occurring errors can be stored as status messages in an error storage device, and if desired, they can be interrogated and corrected at the next service interval.

Starting motor for an internal combustion engine, having a safety device

A circuit arrangement for an engagement relay of a starter mechanism of an internal combustion engine, for bringing two gearwheels in engagement, the circuit arrangement having a switching element which reduces a relay current after a first time period before meshing of the two gear wheels to a determined current value during a second time period, the switching element being formed as a controlling and regulating device which increases a relay current to a predetermined value to a third time period which starts when one gear wheel reaches the other gear wheel.
