- the invention relates to a motor vehicle.
- Modern motor vehicles often have a large number of driver assistance systems which can assist the driver in the course of a driving operation or which can temporarily or permanently remove the vehicle guidance for him.
- the motor vehicle can be fully automated in extreme cases, that is, automatically and without monitoring by the driver, out.
- a driver assistance system also takes over the lateral and / or longitudinal guidance, whereby it must be permanently monitored by the driver.
- driver assistance systems are also used in manual driving or in assisted driving in which the driver continues to perform the transverse or longitudinal guidance of the motor vehicle.
- driver assistance systems can be used during a manual driving operation.
- a support of the driver on many levels is possible, for example, in navigation and automatic distance control.
- driver assistance systems may be confusing for a user.
- the configuration of a plurality of driver assistance systems is also relatively time consuming.
- a method for operating a driver assistance system is known in which the current driving situation is determined on the basis of at least one sensor.
- a dynamic driving limit range is determined, which is used as the basis for a can be output to the driver driving recommendation.
- the driving-dynamic border area and / or the driving recommendation can be adjusted taking into account the current state and / or the ability of the driver and / or at least one optimization criterion.
- operating parameters of other vehicle systems in particular also other driver assistance systems, can be adapted accordingly.
- the choice of optimization criterion described is usually not flexible enough to perform the complete configuration of the driver assistance systems through it.
- the invention has for its object to provide a holistic assistance function that can provide the driver with the functionality of a variety of driver assistance systems and at the same time quickly and easily adaptable to the needs of a user.
- the object is achieved according to the invention by a method for operating a motor vehicle having a plurality of driver assistance systems, comprising the following steps:
- an assistance grade parameter which specifies the driver's assistance level through the entirety of the driver assistance systems
- an additional parameter or several additional parameters relating to the driving operation of the motor vehicle can be set, on the one hand, an assistance grade parameter which specifies the driver's assistance level through the entirety of the driver assistance systems, and, on the other hand, setting an additional parameter or several additional parameters relating to the driving operation of the motor vehicle.
- additional parameters abstract parameters can be used which do not relate to a specific driver assistance system but to the driving operation in general. For example, can be selected by an additional parameter, whether a more dynamic or more consumption-efficient driving is desired or it can be used at least one additional parameter that describes a general type of ride, so for example, whether it is a time-critical ride or if the Driver enjoyment is in the foreground.
- the processing device can automatically determine the manner in which driver assistance should take place and correspondingly configure the individual driver assistance systems by specifying corresponding operating parameters. It can thus be provided with little configuration effort a complex network of assistance functions.
- the individual driver assistance systems thus act together as a holistic assistance function which can inform, warn and correct the driver, in particular in the case of a manual driving operation as required and the driver's wishes, and / or intervene in the driving operation as required.
- This driving function can ultimately support the driver in the manner of a co-driver, driving instructor or copilot.
- the inventive method in particular when exclusively or predominantly informing driver assistance systems are configured, is a kind of configurable coach for driving.
- the assistance grade parameter should be adjustable such that in at least two settings, at least one driver assistance system is active at least in certain driving situations.
- the user interface can be implemented as a graphical menu, via which both the assistant degree parameter and the additional parameter or the additional parameters can be set.
- the assistance grade parameter or the additional parameters can be set quasi-continuously, for example via illustrated sliders, or in several discrete stages, for example via virtual selection buttons. It is also possible to choose between two parameter values by a kind of switch.
- the operation of this menu can be implemented by a touch screen or other controls, such as a rotary push-button, which interact with a display.
- the additional parameter makes it possible to choose between an operating mode of the motor vehicle in which consumption of the motor vehicle is minimized and an operating mode of the motor vehicle in which an anticipated time until reaching a destination is minimized.
- the additional parameter may choose between time efficiency and consumption efficiency.
- This selection can also be multi-level, so that intermediate stages between a time efficiency and a consumption efficiency can be selected. If, for example, a high consumption efficiency is to be achieved, a speed limiter can be activated, driving hints can be given to minimize consumption, a particularly consumption-efficient route can be determined by the navigation system, etc.

- the driver assistance systems can be configured such that an energy-efficient driving operation takes place in order to reduce further discharging of an energy store and thus a time delay during charging. If the motor vehicle is to be guided, for example, on a scenic route, the driver assistance systems can be configured in such a way that a driver is guided to a relatively quiet drive, whereby it can be checked at the same time, for example, whether the driver devotes sufficient attention to the driving operation.
- a first additional parameter may be between a time efficiency and a consumption efficiency of the driving operation and one or more additional parameters can specify boundary conditions for route planning.
- the further additional parameters can in particular have exactly two choices, namely whether a corresponding boundary condition should be active or not.
- the driver assistance system it is possible for the driver assistance system to evaluate provided input data only when it is operated in an active operating mode in order to control at least one vehicle device depending on the input data, the operating parameter specifying whether or in which driving situation the respective driver assistance system in is operated in the active operating mode.
- the vehicle device may be, for example, an actuator which is actuated to carry out a driving intervention, or an information device for outputting an indication to the driver of the motor vehicle.
- Information devices can be, for example, display devices, devices for the output of acoustic signals or actuators for the output of haptic information.
- an actuation can only take place if a control condition evaluating the input data is fulfilled.
- an automatic distance control if active, can control an engine control of the motor vehicle to reduce the drive power and / or a brake of the motor vehicle in order to slow down the vehicle if the input data indicate that a distance to the vehicle in front is below a limit value.
- the automatic distance control is in an inactive operating mode due to the operating parameter, it does not control vehicle devices even if the input data in an active operating mode would lead to a corresponding activation.
- At least one driver assistance system can not control a vehicle device if it is operated in an inactive mode due to the assigned operating parameter (s).
- a driver assistance system it is possible for a driver assistance system to be operated only in certain driving situations in the active operating mode as a function of the operating parameter.
- the activation of the driver assistance system in this case may be, for example, a type of the road being traveled, a state of charge of an energy store, a traffic density, the presence of speed limits, a recognized driver fatigue, a current vehicle speed or, if permissible, a presence of a speed control be dependent.
- a speed limit for certain values of the operating parameter can only be activated if a maximum speed is predetermined on the traveled road and, if a corresponding check is permitted, if it is known that speed checks are carried out in a preceding stretch of road.
- a lane departure warning system can only be activated if an activation condition that evaluates information of a fatigue and / or attention recognition of the motor vehicle is fulfilled.
- the driver assistance system may evaluate input data provided in at least one operating mode of the driver assistance system in order to carry out activation of at least one vehicle device, the operating parameter setting the dependence of the control on the input data. For example, limit values for the input data or a part of the input data can be specified which determine when an activation of the vehicle device takes place.

- the method according to the invention can be used particularly advantageously in cases in which the driver manually guides the motor vehicle or in which he performs at least parts of the motor vehicle guidance manually.
- the inventive method can be used in this case to support the driver needs and coach.
- a motor vehicle in which the method according to the invention is used can be performed highly automated or fully automated.
- a common menu can be provided, in which it is possible to choose between a coached driving operation and a highly or fully automated driving operation, and that at the same time enables a configuration of the coached driving operation according to the invention.
- the method according to the invention for the complete configuration of the driver assistance systems, so that highly automated or fully automated driving operation can be selected by setting a corresponding assistance grade parameter.
- a menu that is used for setting the assistance grade parameter and the at least one additional parameter may additionally include further setting options for the driving operation of the motor vehicle.
- a route type may be switched between a road route, an off-road route, and an automatic route-type recognition.
- a corresponding setting can be taken into account as an additional parameter in the method according to the invention, but it can also serve exclusively to configure individual vehicle components, for example a transmission, an engine control and / or a chassis.
- a navigation system and / or a location-based information service and / or a fatigue-recognition-based driver assistance systems and / or a lane departure warning system and / or a lane change assistant and / or an evasion assistant and / or an assistant for information at intersections and / or junctions and / or a traffic sign display assistant and / or a speed recommendation assistant and / or a speed limit assistant and / or a warning alert against local dangers and / or an efficiency assistant can be used.

- navigation level driver tasks include choosing a destination and departure time, planning a route, scheduling pauses, detecting and responding to congestion and detours, scheduling refueling stops, and the like.
- the web guiding level concerns the selection of reference variables, that is to say in particular of a desired track and a desired speed.
- the associated tasks are a lane selection, a determination of whether a lane change should be made, an ideal line recognition, a planning of avoidance processes, a tempo selection taking into account speed limits and possibly existing speed monitoring, consumption optimization, a determination Optimizing the time required to reach a destination, detecting and responding to weather conditions and the like.

- an automatic gear shift can also be configured in the method according to the invention.
- boost and / or recuperation strategies for an electric driving operation can be predefined.
- a speed recommendation assistant can specify speeds, in particular as a function of a detected or received traffic light state.
- Location-based information services also called location-based services, are mobile services that selectively provide information to the user with the aid of position-dependent data. Depending on the configuration, ie depending on the operating parameters, these can be used to show the driver information, for example via a display, or to output it acoustically. For example, information about petrol station prices, attractions, hotels or similar can be output. The type of output and / or the information provided may depend on the assistant grade parameter and / or on the additional parameter.
- Efficiency assistants may advise a driver, depending on the operating mode, to give more or less throttle to optimize efficiency according to constraints that may depend on the additional parameter and / or the operating parameter.
- hints can be given as to when overtaking may be appropriate, when acceleration or braking should occur, and which trajectory, preferably which ideal line, should be followed.

- One of the additional parameters 2 can here quasi-continuously or with two or more stages between an operating mode of the motor vehicle, in a consumption of the motor vehicle is minimized, and a mode of operation of the motor vehicle in which a probable duration is minimized until reaching a destination select. The driver can thus quickly and efficiently determine whether the driver assistance systems should be configured to help them increase time efficiency or fuel efficiency.
- One or more additional parameters 2 can specify boundary conditions that are evaluated as part of a determination of a driving route of the motor vehicle to a destination by a navigation system of the motor vehicle.
- This may be, for example, boundary conditions that pretend that the vehicle should be loaded or refueled along the route, that the route should include certain points of interest, for example, be landscaped and / or pass hotels or shopping opportunities should be that certain roads should be used or avoided and / or that a destination should be reached particularly quickly or particularly sparingly. From these selected boundary conditions can be concluded in the later course of the process, which type of vehicle is, so whether, for example, a quick achievement of the goal, fuel efficiency or driving pleasure for the driver in the current driving in the foreground. Accordingly, the driver assistance systems can then be configured automatically.

- a predictive speed limiter limiting the maximum speed of the motor vehicle is configured to be active only when the traveled distance has a speed limit. In this case, the speed is limited in such a way that it differs from the predefined maximum speed by an offset, which is determined as a function of one of the given operating parameters.
- an active lane guide is activated, which engages in the driving operation to guide the motor vehicle in the middle of a lane.
- the activation takes place only if it is determined by a fatigue detection of the motor vehicle that the driver is tired or if it is determined by evaluating the previous driving operation that for a given time a monotonous ride, for example a straight ahead on a highway with no or few lane changes, took place.
- a fatigue-recognition-based driver assistance system is activated as a driver assistance system 5, which gives the driver depending on a recognized fatigue pause recommendations.
- This driver assistance system 5 is configured in such a way that points of interest on the route and charging options recognized for the pause recommendations are taken into account.
- the driver wants to reach his destination as quickly as possible and renounce unnecessary assistance functions on his view for the current ride. For this purpose, it activates, for example, the field 7 and deactivates the fields 8 and 9 at the user interface 6, whereby the route planning is carried out in such a way that the fastest possible route is determined.
- the driver assistance systems are configured as explained below in such a way that relatively few driver assistance systems 5 are activated and that maximum time efficiency is achieved.
- the navigation system determines a fastest route.
- the predictive efficiency assistant is configured in such a way that no indication is given to the driver if an efficiency could be increased by a lower throttle. In order to maximize the time efficiency, the driver is given evidence of appropriate overtaking, an ideal line for brisk driving and optimal points for accelerating and braking.
- the predictive speed limit wizard is configured to be active only if there is a speed limit. If an evaluation of information is permitted as to whether speed measurements are being carried out on the track ahead, the Speed Limit Assist can also be configured so that only in the case of speed measurements on the track ahead there is a speed limit. In addition, another offset can be selected with respect to the predetermined maximum speed, as in the example explained above.
- the further driver assistance systems 5 are deactivated by presetting corresponding operating parameters, so that no processing of input data and no control of vehicle systems takes place through them.
- the motor vehicle 12 has an operator interface 6, via which the assistance grade parameter and the additional parameters can be set. As explained above, these parameters are processed by a processing device 3 of the motor vehicle in order to determine the operating parameters 4 for the driver assistance systems 5.
- a control device 13 of the motor vehicle 12 implements the various driver assistance systems 5.
- the control device 13 and the processing device 3 can of course also be designed as a common device.
- the driver assistance systems 5 can in this case, as explained, give instructions to a driver and / or intervene in the driving operation by controlling the vehicle devices 14, 15.
- the vehicle device 14 is, for example, an actuator that enables automatic braking of the motor vehicle 12, and the vehicle device 15 is a display device for giving driving advice to the driver.
- the vehicle devices 14, 15 are shown purely by way of example for further vehicle devices which can be controlled by the various driver assistance systems 5.
