Description

The The invention relates to a device for controlling and / or regulating a motor vehicle generator according to the preamble of claim 1. Such a device is used in motor vehicles Use that have generator management, which the motor vehicle generator by consumption-reducing interventions put into an energy-saving state, in which he however too little or no power provides to put together with an electrical memory to allow that Motor vehicle can give start-up assistance to another vehicle. Of Furthermore, the present invention relates to a generator management system according to claim 4, and a motor vehicle one Control and / or regulating device according to claim 5, a motor vehicle with a generator management system according to claim 6 and a control and / or regulatory procedure accordingly the preamble of claim 7.

In modern motor vehicles take the number of electric and electronic realized functions and thus also the energy demand in the vehicle constantly to. As the reduction of energy and thus fuel consumption The goal of most manufacturers is increasingly becoming generator management systems used, which the motor vehicle generator by consumption-reducing Intervene interference so that the energy consumption of the motor vehicle decreases. Such consumption-reducing interventions can be, for example realize that the generator is partially or fully de-energized. This measure is usually done when the battery is sufficiently charged and the current electrical Load or the vehicle electrical system state permits. In this partially or fully de-energized state of the motor vehicle generator only a comparatively low or no performance to disposal. In this state, the performance of the Motor vehicle generator and the electrical storage is not enough to be able to jump-start another car.

In the prior art, devices are known which are intended to enable a vehicle to provide start-up assistance to another vehicle due to a depleted accumulator. DE 199 29 305 A1 For example, discloses such a device for granting jump-start. The device, which contains a bidirectional DC / DC voltage converter, is inserted between the starting arrangements of two machines, in particular between motor vehicle machines, and makes it possible to grant jump-starting even if the two vehicles involved have different on-board system voltages. However, this device does not guarantee that it is possible to give successful start-up assistance to other vehicles regardless of the state of the motor vehicle generator.

task The invention is to ensure that motor vehicles, which via a consumption-reducing generator management be capable of being used by other motor vehicles to be able to jump start at any time.

These Task is by a control and / or regulating device according to claim 1, a generator management system according to the independent claim 4, a motor vehicle according to the independent claims 5 and 6 and a method for controlling a motor vehicle generator solved according to the independent claim 7. Advantageous embodiments of the invention are the subject of the dependent claims.

Of the The essential idea of the invention is an analysis device provide, with which it can be seen that the motor vehicle as Donor vehicle to give another vehicle jump start. through The analysis device thus becomes the presence of a foreign start scenario determined. In addition, a control and / or regulating device provided, with which, when detected third party scenario the consumption-reducing interventions of the generator management except Set function. This causes that when detected Starter scenario also a vehicle with a generator management is put into the state, enough electrical power ready for a foreign start and therefore at any time is able to jump-start another vehicle.

The Inventive analysis device is preferably set up so that they have different interfaces Can receive sensor and operating and status information, with the aim of identifying whether a possible outrage scenario is present.

To the information received is evaluated and used for the case that detects a possible outrage scenario was, a corresponding signal to the control and / or regulating device sent.

Preferably the analysis device receives sensor information indicating whether the bonnet of the motor vehicle is open is.

A further preferred embodiment provides that the analysis device receives sensor information by means of which it can recognize whether the driver's door has been opened while the engine of the motor vehicle is running. If this is the case, the control and / or regulating device deactivates the consumption-reducing interventions of the generator management until a vehicle speed of more than 0 km / h is reached. This is based on the assumption that the driver for strangely start the vehicle usually leaves with the engine running to open the hood and to contact the jumper cables.

Of course may also provide other information from the analyzer used to detect a foreign startup scenario. It is For example, imagine that a sensor detects when jumper cables be contacted. Likewise, the driver could be present a startup help scenario manually via a control element for example, signal the on-board computer.

Preferably The sensor and operating and status information will go through so-called polling (cyclic polling) received. Equivalent but is the use of interrupt requests or a recursive structure.

The Control and / or regulating device is preferably set up such that it can actively influence the generator power. In a preferred embodiment finds the control or regulation of the generator, preferably by a controller or controller of the generator management system. In this case, the tax and / or regulating device with the generator management system connected.

In However, it is also possible in another embodiment that the control and / or regulating device directly the generator and / or controls and / or controls the engine control or engine. In this case it is with the engine control and / or the engine connected.

In advantageous because space saving and cost-effective Execution are the analytical device and the control and / or control device preferably as a structural unit executed.

Preferably are the analysis device and the control and / or regulating device contained in the generator management system.

in the Following are some example embodiments of the invention explained in more detail with reference to drawings.

there demonstrate:

1 a block diagram of a preferred embodiment of the device according to the invention, wherein the control and / or regulating device is connected to the generator management system;

2 a block diagram of another preferred embodiment of the device according to the invention, wherein the control and / or regulating device are connected directly to the generator and the motor and

3 a flowchart illustrating a preferred embodiment of the method according to the invention.

1 shows in block diagram form a preferred embodiment of the device as a system whose central components are an electrical memory ( 10 ), an electric generator ( 12 ), an engine ( 13 ), a generator management system ( 16 ), an analysis device ( 15 ), a control and / or regulating device ( 14 ) as well as sensors ( 17 ) are.

The electric storage ( 10 ) and the electric generator ( 12 ) are connected electrically, for example by electrical lines. The same applies to the generator management system ( 16 ), which is electrically connected to the engine ( 13 ) and the electric generator ( 12 ) connected is. The analysis device ( 15 ) and the control and / or regulating device ( 14 ) are shown as a structural unit, which in turn electrically, for example by electrical lines, with the generator management system ( 16 ) connected is. The motor ( 13 ) and the electric generator ( 12 ) are operatively connected, for example by a V-belt.

The analysis device ( 15 ) receives via the electrically connected sensors ( 17 ), Sensor and operational and status information to help detect the presence of an off-premises scenario. As soon as a possible external start scenario has been detected, a corresponding signal is sent to the control and / or regulating device ( 14 ). This controls or regulates the generator management system ( 16 ) such that all consumption-reducing interventions in the generator control are disabled.

A Another possibility is that not all, but only so many consumption-reducing interventions in the generator control be put out of action that enough power to Is available to jump-start another vehicle can.

2 shows a block diagram of another embodiment of the device. The structure of this system essentially corresponds to that in the 1 illustrated block diagram. To avoid repetition, reference is therefore made to the preceding statements. The same components are provided with the same reference numerals and the embodiment according to 1 information provided apply in the context of the present combination of functional and structural characteristics.

The analysis device ( 15 ) and the control and / or regulating device ( 14 ) are again shown as a structural unit, which this time, however, in contrast to the embodiment according to 1 , via electrical connections, for example electrical lines, directly to the generator ( 12 ) and the engine ( 13 ) and controls or regulates them in such a way that all or some consumption-reducing interventions the generator management system ( 16 ) are disabled.

The flowchart after 3 starts with start ( 30 ). It followed a block ( 31 ) in which the analyzer receives the sensor and operating and status information. Surrendered ( 32 ) from the data received is not the presence of a foreign start scenario, the sensor and operating and status information ( 31 ). In the other case, that is, if a foreign start scenario is detected, in a following block ( 33 ) sends a corresponding signal to the control and / or regulating device. Then in the next block ( 34 ) checked whether sufficient power is available to grant jump-start. If this is the case, the end immediately follows ( 37 ) of the procedure. In the other case, that is, if there is not enough power to provide jump-start, the following block ( 35 ) sends a corresponding signal to the generator management system. The generator management system now sets - marked by a block ( 36 ) - the consumption-reducing interventions in the generator control out of function. This in turn closes the end ( 37 ) of the procedure. This procedure is used iteratively.
