The invention relates to a starting method for internal combustion engines in motor vehicles, comprising a start-stop system, and to a starting device () for carrying out said method, said starting device comprising a starter motor () and an insertion device () which axially inserts a slip-on pinion () into a crown gear () of the internal combustion engine when a stop cycle begins. In order to minimize the period until the engine can be restarted, the pinion () is resiliently inserted into the still rotating crown gear () by means of a pressure spring () when the stop phase begins, once the internal combustion engine () is switched off but before it comes to a standstill and with the starter motor () switched off.

Method and device for start-stop systems of internal combustion engines in motor vehicles

The invention relates to a method for meshing a starter pinion () of a starting device () into a ring gear () of an internal combustion engine (). The internal combustion engine () has a driveshaft (), and the starting device () has a starter motor (), said driveshaft () having a variable rotational speed (n). The internal combustion engine () is switched off in a method step (S1), and the starter pinion (), which is not being rotationally driven by the starter motor (), is then advanced in the direction of the ring gear () by a toe-in actuator () by means of a toe-in force (FV) in a method step (S2) until the starter pinion contacts the ring gear. A meshing force (FE) is then exerted onto the starter pinion () in a controlled manner in an additional method step (S3) in order to mesh the starter pinion () into a tooth gap () of the ring gear ().

Method for meshing a starter pinion of a starting device into a ring gear of an internal combustion engine

A vehicle having an internal combustion engine, a transmission having multiple gears and a transmission input shaft, and a recuperation system for recovering electrical energy, the recuperation system being configured for changing a speed value of the internal combustion engine during a gear change from an actual gear into a setpoint gear to a speed value of the transmission input shaft in the setpoint gear.

Vehicle having a recuperation system

A method is described for engaging a starting pinion of a starting device with a ring gear of an internal combustion engine, the starting pinion having a peripheral speed and the ring gear having a peripheral speed, the starting pinion being pushed forward axially along its axis of rotation, the starting pinion making contact with the ring gear at a peripheral speed which is lower than the peripheral speed of the ring gear.

The invention relates to a starter (), to a device for starting a starter motor, to a device for detecting an engaged state of a starter pinion, to a method for starting a starter motor, to a method for detecting an engaged state of a pinion () in a corresponding gearwheel, to a computer program and to a computer program product, wherein the method for detecting an engaged state of a pinion () in a corresponding gearwheel, in particular an engaged state of a starter pinion in a gear rim of a starter (), comprises applying a current to a starter relay () for switching the pinion () and detecting at least one current flow parameter of the current flow, wherein the detected current flow parameter is set in relation to potential pinion positions and a pinion position associated with the detected current flow parameter is selected and is thus detected.

Starter having engagement detection function

A device for starting an internal combustion engine of a motor vehicle is described, which has a starter motor, an engaging relay, a starting current relay, a main current relay, a control unit and a switching module situated between the relays named and the control unit. The control unit is an engine control unit of the motor vehicle. The switching module has inputs which are connected to one output, respectively, of the engine control unit, and has outputs at which control signals for the relays named are provided. The outputs of the engine control unit are small signal outputs.

A switching device has an electromagnetic switching element and a controller, the switching element including two coils on one core which act on a shared armature. In order to implement an operation of the armature to be activatable as rapidly and simply as possible with low power consumption, the controller is designed to have a switch in the current path of the coil in each case to activate each coil.

Switching device, starting device, and method for an electromagnetic switching device

A method and a device for controlling an internal combustion engine having a central control unit and a peripheral control unit are described. The central control unit transmits request signals to the peripheral control unit. At least two load circuits receive control signals from the peripheral control unit. The peripheral control unit checks the request signals and/or additional signals for plausibility.
