Technical Field

The invention relates to a method and a device for operating a hybrid vehicle.

Background

Hybrid vehicles can be operated both by means of an internal combustion engine (brenkraftmaschine) and by means of an electric motor. The electric motor is supplied with energy from an electric energy storage. The electrical energy store may be, for example, a battery or a fuel cell. Depending on the state of charge (SOC) of the electric energy store, the effective travel of the hybrid vehicle in the electric mode can be changed.

DE 102016206743 a1 discloses an operating unit for a hybrid vehicle, which includes an electric drive machine and an energy store for storing electrical energy for operating the electric drive machine. The operating unit comprises a user interface (Benutzerschnittstelle) which enables a user to input a target state of charge (zielladeutzund) for the energy store or to activate an automatic adaptation of the state of charge of the energy store. Furthermore, the operating unit comprises a control element which is designed to cause the state of charge of the energy store to be adapted as a function of an input at the user interface.

Disclosure of Invention

The object of the invention is to improve a method and a device for operating a hybrid vehicle.

According to the invention, this object is achieved by the method according to the invention and the device according to the invention. The invention is advantageously embodied in the form of a description.

In particular, a method for operating a hybrid vehicle is provided, wherein a target state of charge of an electrical energy store of the hybrid vehicle is specified as a function of a target location of the hybrid vehicle, wherein the hybrid vehicle is operated such that the electrical energy store has the specified target state of charge when the target location is reached, and wherein the target state of charge is learned for the target location (anlernen) and is automatically adjusted after the learning when the hybrid vehicle is driven to the associated target location.

Furthermore, in particular, an apparatus for operating a hybrid vehicle is provided, which comprises a control device, wherein the control device is set up to operate the hybrid vehicle such that an electrical energy store of the hybrid vehicle has a defined target state of charge when reaching a target location, wherein the target state of charge can be defined as a function of the target location of the hybrid vehicle; and the target state of charge is learned for the target location and is automatically adjusted after the learning when driving to the associated target location.

The method and device enable the automatic selection of a target state of charge associated with a target location based on past performance (Verhalten) of a driver of the hybrid vehicle. For which a target state of charge is learned for the target site. The learned target state of charge for the target site is then retrieved and automatically adjusted when the target site is reselected. The state of charge of the electrical energy store of the hybrid vehicle can thereby be adapted at all times to the presets (Vorgabe) or desires of the user of the hybrid vehicle. This increases the comfort, since the presetting of the target state of charge does not have to be entered again by the user after learning.

The electrical energy store may be, for example, a battery or a fuel cell. The electrical energy store has, in particular, a charge sensing device (Ladesensorik), by means of which the state of charge (SOC) of the electrical energy store can be detected. In particular, the detected state of charge is supplied to the control unit.

The target location is in particular a navigation target, that is to say a target location of a current travel route (Fahrstrecke) of the hybrid vehicle which is entered into a navigation device of the hybrid vehicle. The target location is delivered to the control device.

The learned target state of charge may be stored, for example, in association with the corresponding target site or in a database. The database is set up, for example, in the memory of the control unit or stored there.

The components of the device, in particular the control unit, can be designed individually or jointly as a combination of hardware and software, for example as a program code executed on a microcontroller or microprocessor. However, it is also possible to configure the components individually or jointly as an application-specific integrated circuit (ASIC).

In one embodiment, it is provided that the target state of charge is learned as a function of at least one user input. In the simplest case, the target state of charge specified by the user for the target site can be received for this target site and stored, for example, in the database described above.

In one embodiment, a target state of charge specified as a function of the target location is received in the learned framework as a target state of charge for the target location as a function of a frequency (haeufigkey) specified by the user for the target location. Thus, the target state of charge is received only when the target state of charge is used or prescribed frequently enough. For example, it may be provided that the target state of charge is received for the target location by the user specifying at least three times, five times, ten times, etc., when driving to the target location.

In one embodiment, when a target location that has not been selected before is selected, it is provided for the user to ask in a learned framework whether a defined target state of charge is to be stored as the target state of charge for the selected target location. This allows the specified target state of charge to be linked to the target location immediately (i.e., even if it is entered by the user for the first time).

In one embodiment, a frequently traveled route is identified, wherein after the frequently traveled route has been identified, the user is asked in the learned framework whether the target state of charge and/or which target state of charge should be stored for the target location corresponding to the frequently traveled route. The target state of charge may also be learned and stored if the target location (e.g., navigation target) and target state of charge are not specified by the user. The identification of the frequently traveled route sections can be carried out, for example, by means of a pattern recognition method (musterkennnunsverfahren).

In an improved embodiment, it is provided that the target state of charge specified by the user in the past for a frequently traveled route is suggested to the user as the target state of charge when queried. Thus, the user need only confirm or reject the target state of charge that has been previously specified. Interaction with the user for learning the target state of charge may thus be efficiently designed or designed.

In one embodiment, provision is made for the user to be advised of the target state of charge according to a defined target location on the basis of at least one further criterion. Additional criteria may thus be taken into account when proposing the target state of charge.

In a further embodiment, it is provided that the at least one further criterion comprises at least one of the following: target states of charge of other fleet participants of a fleet of vehicles (Fahrzeugflotte), target states of charge of other users, charging pile availability at a target site, green energy availability at a target site (oekostromvverfuegbarkeit). By suggesting a target state of charge for other fleet participants of the vehicle fleet and/or a target state of charge for other users, selection by the user may be simplified because already existing empirical knowledge of the other fleet participants and/or other users may be leveraged. The charging post availability and/or the green energy availability allow conclusions to be drawn as to how far the hybrid vehicle has to be able to travel electrically at the target location in order to reach the next charging possibility.

In one embodiment, the target state of charge is suggested to the user on the basis of at least one lock zone characteristic if the target location selected by the user is within a lock zone (Sperrzone) for the internal combustion engine. The characteristic of the locking region is, for example, the distance from the outlet of the locking region, from which the operation of the internal combustion engine is again permitted. This distance is accompanied by the minimum effective stroke and therefore the minimum state of charge required in the electric mode, from which the target state of charge can be derived.

Further features for the design of the device result from the description of the design of the method. The advantages of the device are the same advantages in this case as in the design of the method.

Drawings

The invention will be explained in detail below with reference to the drawings according to preferred embodiments. Wherein:

fig. 1 shows a schematic illustration of an embodiment of a device for operating a hybrid vehicle.

Detailed Description

Fig. 1 shows a schematic illustration of an embodiment of a device 1 for operating a hybrid vehicle 50. The apparatus 1 comprises a control device 2. The device 1 implements the method illustrated in this publication.

The control device 2 is set up to operate the hybrid vehicle 50 such that the electrical energy store 51, for example a battery, of the hybrid vehicle 50 has a defined target state of charge 10 when it reaches the target point. In this case, the control device 2 controls, in particular, the portion of the route covered by means of the internal combustion engine drive (brenkraftratibe) 52 and the portion of the route covered by means of the electric drive 53 of the hybrid vehicle 50 when driving through the route. The operation of the hybrid vehicle 50 by means of the internal combustion engine drive 52 generally allows charging of the electrical energy store 51 in addition to propulsion. Whereas during operation of the electric drive 53, electrical energy is drawn from the electrical energy store 51.

The detected state of charge 57(SOC) of the charge sensing device 56 of the hybrid vehicle 50 is supplied to the control unit 2, so that the control unit 2 knows the state of charge 57 of the electrical energy store 51.

The target state of charge 10 may be specified according to the target location. This can be done, for example, via the user input 20 at a display and operating device 54, for example a touch screen, of the hybrid vehicle 50. The target state of charge 10 may also be specified, for example, using an input to a target location of the navigation device 55 of the hybrid vehicle 50.

The control device 2 is set up to learn the target state of charge 10 for the target location and to automatically adjust it when driving to the associated target location after learning. For this purpose, a database is set up in a memory (not shown) of the control device 2, for example, in which the learned target state of charge 10 is associated with the respective target location. If the control device 2 knows the target location of the travel section of the hybrid vehicle 50, the control device 2 checks whether a target state of charge 10 is stored in the database for this target location. If this is the case, the control device 2 calls up the associated target state of charge 10 and automatically sets it to a preset value. During the driving route, the control device 2 then controls or regulates the portion of the internal combustion engine drive 52 and the portion of the electric drive 53 at the driving route as a function of the target state of charge 10 and the detected state of charge 57, so that the target state of charge 10 of the electric energy store 51 is achieved when the target point is reached.

It may be provided that the target state of charge 10 is learned from at least one user input 20. The user input 20 is implemented, for example, on a display and operating device 54 of the hybrid vehicle 50.

It may be provided that the target state of charge 10 specified according to the target location is received in the learned framework as target state of charge 10 for the target location according to the frequency specified by the user for the target location. If the same target state of charge 10 is specified for a target location, for example, with a frequency of at least three, five or ten times, etc., it is automatically stored for this target location, for example, in a database, and retrieved and automatically adjusted when the target location is reselected.

It can be provided that, when a target location that has not been selected before is selected, the user is asked in the learned framework whether a defined target state of charge 10 is to be stored as target state of charge 10 for the selected target location. The user can then store the target state of charge 10 for the target location when driving to it for the first time. The interrogation can be implemented, for example, on the display and operating device 54, the control device 2 transmitting corresponding interrogation signals 11 to the display and operating device 54, for example.

After the identification of the frequently traveled travel section, it can be provided that the user is asked after the identification of the frequently traveled travel section whether the target state of charge 10 and/or which target state of charge 10 is to be stored for the target location corresponding to the frequently traveled travel section. In particular, it can be provided that the control device 2 obtains navigation data 15 from a navigation device 55 of the hybrid vehicle 50 for this purpose, from which travel sections and frequencies can be derived. The interrogation can be implemented, for example, on the display and operating device 54, the control device 2 transmitting corresponding interrogation signals 11 to the display and operating device 54, for example.

In an improvement, it may be provided that the target state of charge 10 specified by the user in the past for the frequently traveled route section is suggested to the user as the target state of charge 10 when queried. The interrogation can be implemented, for example, on the display and operating device 54, the control device 2 transmitting corresponding interrogation signals 11 to the display and operating device 54, for example.

It can be provided that the target state of charge 10 is suggested to the user according to a defined target location on the basis of at least one further criterion 30. The at least one further criterion 30 can be supplied to the control device 2, for example, via a communication interface (not shown). The at least one further criterion 30 can be queried by the control device 2 for a server (not shown), for example, and transmitted from it to the control device 2.

In this case, it can be provided, in particular, that the at least one further criterion 30 comprises at least one of the following: target states of charge 10 of other fleet participants of the vehicle fleet, target states of charge 10 of other users, charging pile availability at the target site, green power availability at the target site.

Furthermore, it can be provided that, if the target location selected by the user is within the lock range for the internal combustion engine, the target state of charge 10 is suggested to the user on the basis of at least one lock range characteristic. In order to determine whether the selected target location is in the locked region for the internal combustion engine, the navigation data 15 can be evaluated by the control device 2, for example. If it is determined that the selected target location is in the block zone, the control device 2 calculates a target state of charge, wherein the target state of charge is calculated such that the hybrid vehicle 50 can reach the exit of the block zone from the target location only by means of the electric drive 53. The calculated target state of charge is transmitted to the display and control device 54 in the form of the corresponding query signal 11 and is suggested to the user for selection on the display and control device 54. The target state of charge 10 is received for the target site after the user input 20 is made.
