20100131175 | FUEL INJECTION SYSTEM AND METHOD FOR INJECTING FUEL - The invention relates to a fuel injection system having at least one fuel injector, which includes an electrically operable actuator. In order to reduce the hydraulic distances between two injections, a voltage-smoothing or voltage-dampening electric device is connected in parallel to the actuator. | 05-27-2010 |
20110202264 | METHOD AND CONTROLLER FOR A STARTER DEVICE OF AN INTERNAL COMBUSTION ENGINE - A method for controlling a starter device is described, having a starter motor, a meshing device and a starter pinion for meshing into a ring gear of an internal combustion engine in a motor vehicle, the meshing device for meshing the starter pinion being activated by the controller, in particular for a starting/stopping operating strategy. In order to improve vehicle comfort, in that the internal combustion engine may be restarted significantly more quickly, at least one meshing value of the meshing device for meshing the starter pinion is detected by a detecting device, stored in the controller as a reference value, and evaluated. | 08-18-2011 |
20110246050 | METHOD AND DEVICE FOR START/STOP CONTROL OF AN INTERNAL COMBUSTION ENGINE - In a method for controlling a start/stop operation of an internal combustion engine in a motor vehicle, the controller activates a starting device which has a starter motor and a meshing device for the purpose of starting the internal combustion engine and of executing a start/stop operation, the rotational speed and position of a crankshaft of the internal combustion engine being detected with the aid of a detector device. To provide vehicle comfort in start/stop mode and to implement meshing of a starter pinion with the ring gear at a coasting rotational speed at reduced noise and wear, a point in time is determined for meshing with the ring gear of a coasting internal combustion engine after the internal combustion engine has been shut down. | 10-06-2011 |
20120158274 | Control device for an electrical high-current consumer, method for operating same, and computer program product - A control device for an electrical high-current consumer is provided, e.g., a starter controller for a starter motor of an internal combustion engine in a motor vehicle, in a circuit having an internal ohmic resistor and further ohmic resistors, e.g., line resistors. The control device includes a microcomputer having a memory. To ensure a control device for standardized, defined control of the high-current consumer on different vehicle platforms, the control device includes an adapter having the microcomputer for adapting to the individual overall ohmic resistance of the circuit. | 06-21-2012 |
20120175890 | Control and method of a starter motor for a starter device - A control is described for a starter device of an internal combustion engine in a vehicle having a starter motor, a first current path and at least one additional second current path, which is connected in parallel to the first current path, for energizing the starter motor, the first current path having an switching device, in particular a starter relay. In order to improve an energization of the starter motor, the control is in operative contact with a testing device for checking a switching state of the switching device and provided with an adapter for adapting the energization of the switching device. | 07-12-2012 |
20120191329 | METHOD FOR OPERATING A CONTROLLER FOR A STARTER DEVICE, CONTROLLER, AND COMPUTER PROGRAM PRODUCT - A method is described for operating a controller for a starting apparatus for starting an internal combustion engine in a vehicle, the controller controlling an engagement apparatus, which encompasses the starting apparatus, so as to engage a starter pinion into the ring gear of an internal combustion engine, in particular using a start-stop operating strategy. In order to improve vehicle convenience by the fact that start-stop operation can be implemented with quick and reliable availability of the internal combustion engine, at least one operating parameter of the engagement apparatus is sensed and evaluated by the controller, and the controller adapts the control of the engagement apparatus to the at least one operating parameter. | 07-26-2012 |
20120200093 | CIRCUIT CONFIGURATION FOR A STARTING DEVICE - A circuit configuration for an electric machine, e.g., a starter motor for starting an internal combustion engine in a motor vehicle, includes a current limiting device for limiting a starting current of the electric machine. The circuit configuration includes a bridging device for bridging the current limiting device. | 08-09-2012 |
20120216769 | METHOD AND DEVICE FOR CONTROLLING A STOP-START PROGRAM - A starter is supplied with current for a certain current feed duration during meshing of a starter pinion of the starter with a coasting internal combustion engine. The current feed is shut down after reaching the certain current feed duration and an induced voltage is measured. The measured induced voltage is compared with a reference voltage and the current feed duration for a subsequent current feed is set as a function of the comparison result. | 08-30-2012 |
20130000585 | STARTER SUPPLY NETWORK - A starter supply network having a first energy source for the primary energy supply of a starter motor, the first energy source being coupled to a network terminal of the starter supply network; a second energy source; and a coupler, which is configured to couple the second energy source to the network terminal as a function of a starter motor current delivered by the first energy source, in order to counteract a reduction in the starter motor current. | 01-03-2013 |
