Description

Activate a driving function for automated driving

The invention relates to a driving system with a driving function for

automated driving for a motor vehicle and the driving system associated user interface for activating the driving function. Furthermore, the invention relates to a method for activating a driving function for automated driving for a motor vehicle.

The term "automated driving" can be understood as meaning driving with automatic longitudinal or lateral guidance or autonomous driving with automated longitudinal and lateral guidance to act a time-limited driving in the context of parking or maneuvering. The term

"Automated driving" includes automated driving with any degree of automation an assisted, semi-automated, highly automated or

fully automated driving. These degrees of automation correspond, for example, to the definition of the Federal Highway Research Institute (BASt) (see BASt publication "Forschung kompakt", Issue 1 1/2012) In assisted driving, the driver executes the longitudinal or transverse guidance while the system performs the other function In Partial Automated Driving (TAF), the system manages the longitudinal and lateral guidance for a certain period of time and / or in specific situations (eg when parking), whereby the driver must permanently monitor the system as in assisted driving In Highly Automated Driving (HAF), the system manages longitudinal and lateral guidance for a period of time (eg when driving on the highway) without the driver having to monitor the system permanently, but the driver must be able to monitor the system in a certain amount of time In fully automated driving (VAF), the system can be used for a specific application In all cases driving in all situations

cope automatically; no driver is required for this application. The above four degrees of automation are in accordance with SAE levels 1 to 4 of the SAE J3016 (SAE - Society of Automotive Engineering) standard. For example, Highly Automated Driving (HAF) complies with Level 3 of the SAE J3016 standard. Furthermore, the SAE level 5 is provided in SAE J3016 as the highest degree of automation, which is not included in the definition of BASt. SAE level 5 is driverless driving, which allows the system to automatically handle all situations like a human driver throughout the journey; a driver is generally no longer required.

In order to activate a driving function for automated driving, it is generally customary to actuate a control element such as a push-button. This is described, for example, in document US 2015/0283998 A1. Other input modalities such as speech or gestures are conceivable. It is in response to the operation of the control tries to activate the desired driving function. If the driving function is not available, generally a feedback is given about its unavailability (eg "automated driving currently not available"). Furthermore, it is for example from US 2015/0283998 A1, the

DE1020131 10864 A1 or DE 10 2007 029 594 A1 discloses the

Availability of a driving function for automated driving even without operating the control element to signal the driver, for example in the instrument cluster, in the head-up display (HUD) or on the

Control element for activating the driving function itself. If the driving function is activated by selecting a menu item on a screen, the menu item can be hidden or grayed out if the driving function is unavailable, so that the menu item can not be selected. A driving function for automated driving (eg, a highway pilot for highly automated driving on a highway) is often a vehicle function that is not easily predictable in its availability to the user. The availability of a driving function for automated driving, for example, the vehicle speed, the

Road type, the traffic density, the recognition of lane markings (in the case of an automated cross-leadership) or in the case of a driving function for highly or fully automated driving the presence of a sufficiently fast communication connection to a back-end server or the release of a section of road for fully or fully automated driving depend.

Therefore, it is cumbersome for the driver to have to test the function availability again and again, for example, by pressing a control element to activate the driving function until the driving function is finally available, or to observe the availability of the driving function, if the availability even without operation the control element is signaled. It is an object of the invention to provide a driving system with a driving function for automated driving for a motor vehicle, which even with frequent NichtVerfügbarkeit the driving function by a high

Ease of use with low operating costs. It is a further object of the invention to provide a correspondingly advantageous method for

Activate a driving function to indicate automated driving.

The object is solved by the features of the independent claims. Advantageous embodiments are described in the dependent claims. It should be noted that additional features of a claim dependent on an independent claim without the features of the independent claim or only in

Combination with a subset of the characteristics of the independent

Claim can form its own and independent of the combination of all features of the independent claim invention, the subject of an independent claim, a

Divisional application or a subsequent application can be made. This applies equally to technical teachings described in the specification, which may form an independent invention of the features of the independent claims.

A first aspect of the invention relates to a driving system with at least one driving function for automated driving for a motor vehicle, in particular for a passenger car. The driving function is a driving function for automated driving with automated longitudinal and / or transverse guidance. For example, it is a driving function for highly or fully automated driving over a longer distance with automated longitudinal and transverse guidance (for example, a motorway pilot function), wherein the driver does not need to monitor the driving system permanently. The driving system has a user interface that has a

Input component for signaling the driver-side desire for activating a driving function for automated driving to the driving system has. The input component comprises, for example, a control element, in particular a steering wheel, for example a control key. The driver's wish could, for example, by a

corresponding voice input or be communicated by a corresponding gesture to the driving system. If the driving system supports several alternative driving functions for automated driving, the individual driving functions can each be assigned different ones

Controls be provided, each control element is used to signal the driver-side desire for activating the respective operating element associated driving function. Alternatively, in the case of several driving functions, it is also possible to provide a single operating element that generally signals the driver-side request for any driving function for automated driving.

The user interface further includes an output component that is operable to offer the driving function for automated driving

Availability to the driver serves. The output component is, for example, an indicator in the vehicle cockpit, in particular an indicator in the instrument cluster or a steering wheel display, or a head-up display. Alternatively or additionally, the offer may also be made acoustically (eg a simple signal tone or a voice output) and / or haptically (eg via the steering wheel or over the seat).

Furthermore, the user interface has an acceptance component for the driver-side acceptance of the offer of the driving function for automated driving. The acceptance component may be further

Control element or act on the same control element of the input component. An assumption about an acceptance gesture or a voice command would also be conceivable. Preferably, the acceptance component comprises the User interface, however, at least one control element for manual vehicle guidance, such as a steering wheel, an accelerator pedal or a

Brake pedal, wherein the driver-side acceptance of the offer in the case of release of the control element is detected (for example, releasing the steering wheel with his hands or releasing the accelerator pedal with the foot).

The driving system is set up, via the input component, a driver-side request for activating a driving function for

to accept automated driving. For example, the function is not activated by means of a control element, which is always available on the steering wheel and is always available, but merely expresses the desire for activation on the part of the driver. In response, the system is virtually biased to the availability of the

Driving function to make the driver with a preferably low operating cost acceptable offer to the driver.

If the driving function is not immediately available anyway, in this biased state of the driving system at least as long

(For example, at certain intervals) the availability of

Driving function for automated driving tested until it is found that the driving function for automated driving is finally available. The availability will preferably continue to be checked thereafter; the

Availability can also be checked before accepting the driver's request to activate a driving function.

The user interface is preferably configured to communicate the presence of the prestressed system state to the driver, in which the driver-side request for activating a driving function has been registered by the system and the driving system is waiting for the availability of the driving function. The state of the bias voltage is thus preferably communicated to the user. For example, this may be indicated by an ad in the

Vehicle cockpit, for example, with the text "Automated driving activated, if available. "Alternatively or additionally, this can also be done by visualization on a control element which serves to signal the driver's wish, for example, the control element illuminates with a specific light color.

Time after receipt of the driver's request for

Activating a driving function is done via the output component of the

User interface the driving function for automated driving offered to the driver after the availability of the driving function was finally determined (positive). The range of functions can be visual, acoustic or haptic.

For example, this is shown in an advertisement in the vehicle cockpit,

especially in the combo display, in the context of offering the

Driving function indicates that the driving function is available (eg

"Automated driving available, please enable steering wheel and

Release the accelerator pedal ").

It is advantageous if the user interface is set up, via the output means an indication to the driver to a necessary acceptance treatment to be undertaken via the acceptance means for accepting the

To give functional offers. For example, a text hint or graphic symbol may be displayed on the display, which will prompt the driver to release the steering wheel and / or accelerator pedal (eg, "release the steering wheel and accelerator pedal to activate, respectively).

If the driving function is a driving function with at least automated lateral guidance, the driving function can also be offered after ascertaining its availability via a light display in the steering wheel (for example in the steering wheel rim, in the steering wheel spokes or in the steering wheel impact pot). For example, the light indicator in the steering wheel rim illuminates to offer the driving function in a right and a right left portion of the steering wheel, in particular the steering wheel rim. This signals to the driver that there is a range of functions for the at least automated lateral guidance and that the offer can be accepted by releasing the steering wheel. After the offer of functions has been accepted, the state of the steering display and the

For example, the steering wheel indicator lights up as a closed ring to signal that the drive function is now active.

If the driver wants to accept the offer for the driving function, this is about the acceptance means of the user interface a

Make acceptance treatment and the driving system will detect a driver-side acceptance of the offer of the driving function via the acceptance component of the user interface. If the driving function is a driving function with at least automated longitudinal guidance or with at least automated lateral guidance, the acceptance component preferably comprises at least one operating element for manual longitudinal guidance or at least one operating element for manual transverse guidance. The driving system is set up in this case to determine that the driver has released the operating element, wherein a driver-side acceptance of the offer of the driving function is determined by the release of the operating element. Alternatively, the driver assistance system can also be designed based on a release of the

Control element to determine the assumption. In the case of a steering wheel, the term "releasing" can be understood to mean either only complete release with both hands or alternatively only unilateral release with one hand (while the other hand still remains on the steering wheel).

For example, the driving function is a driving function with at least automated lateral guidance, in which case the acceptance component comprises the steering wheel of the vehicle. A driver - side acceptance of the offer of the driving function is recognized on the basis of the finding that the Driver has his hands off the steering wheel. If the driving function in addition to the automated lateral guidance also an automated

Longitudinal guide, may also be required to accept the offer in addition to the release of the steering wheel and the release of the accelerator pedal.

In response to the determination of the driver-side acceptance of the offer, the driving function for automated driving is activated, i. H. Automated driving is started. In the above example it was assumed that the

Adoption of offer the driver takes both hands off the steering wheel. Depending on the implementation of the system, it may alternatively or additionally be provided that the driver releases only one side of the steering wheel in order to accept the offer of the transverse guidance (ie only one hand releases the steering wheel, with the other hand holding the steering wheel). This is the case, for example, if complete release of the steering wheel, for example for legal reasons, would not be permitted in a partially automated or assisted mode of operation. For example, if an automated transversal guidance in the sense of an assisted or semi-automated driving is available when driving on the highway, the system could be designed so that it would be sufficient to take only one hand off the steering wheel (if the driver by itself takes both hands from the steering wheel, preferably this would also enable the lateral guidance). For example, in the case where the driving function for automated driving is a rearward parking function with automated longitudinal and lateral guidance (semi-automated operation), the vehicle offers this parking function according to its availability, for example, and requires the driver to release the foot pedals and to take both hands off the steering wheel, since the expected steering angle in this case are very large (a hand on the steering wheel disturbs in this case) and the speed is low. If the release of the steering wheel with one hand from the system for accepting the offer can be determined, it can be provided that a release of the steering wheel with both hands by the system is also understood as an assumption. Alternatively it can be provided that when releasing the steering wheel with both hands (in contrast to letting go of the steering wheel with only one hand) no acceptance of the offer is possible.

The operating concept according to the invention for activating the driving function is characterized by a high degree of operating convenience: the operating effort for activation is low, even if the driving function is temporarily unavailable; it is not necessary to repeatedly test the functional availability by actuating a control element. Compared to systems that the

To indicate availability of the driving function, the availability of the

Function not initially observed and wait until the driver of the driver can press a control element to activate the driving function.

It is advantageous if the acceptance component of the user interface also serves for the driver-side withdrawal of a previously made assumption. In this case, the driving system is set up via the

Acceptance component to determine whether the driver has taken back a previously made acceptance. In response to the determination of the withdrawal, the active driving function is terminated and preferably the driving system is put into a state in which the driving function for automated driving is offered to the driver again via the output component (if the driving function is still available).

About the acceptance component can thus accept the

Function range are easily reversed, so that can easily be changed between active driving function and aktivierungsbereiter driving function. A driver-side withdrawal of an assumption already made may, for example, consist in the driver carrying out an action contrary to the action taken in the context of the acceptance via the user interface acceptance means; this is then preferably determined by the driving system. For example, it is in the

Acceptance treatment to let go of a control element (eg, the steering wheel and / or the accelerator pedal). For determining a driver-side withdrawal of the assumption, for example, it is determined that the operating element is actuated or touched again. It may be necessary to determine that the driver is retyping the control to prevent it from being accidentally touched again. The driving function is, for example, a driving function with at least automated lateral guidance (for example lane keeping assistance without longitudinal guidance, partially automated driving or highly automated driving). In this case, the acceptance components of the user interface preferably comprises a manual lateral guidance control element (typically the steering wheel). The driving function may alternatively or additionally be a driving function with at least automated longitudinal guidance

(For example, Abstandstempomat, semi-automated driving or highly automated driving). In this case, the includes

Accept components of the user interface preferably

Operating element for manual longitudinal guidance (for example the accelerator pedal).

The driving system is set up to determine that the driver is the driver

Control element has released, and a driver-side acceptance of the

Determine offer of the driving function based on the release of the operating element. This has already been described in detail above. Furthermore, the driving system is set up to detect a driver-side withdrawal of the release of the operating element and on the basis of which a driver-side The withdrawal of an assumption already made. It may be necessary to determine the withdrawal of the release, that it is determined that the driver intentionally pressed the control again to exclude that accidental contact already takes back the acceptance again.

The acceptance component may include, for example, a steering wheel and / or an accelerator pedal. The driving system can be set up

Detecting a driver's acceptance of an assumption already made, if the driver has taken his hands back to the steering wheel and / or the driver overrides the steering wheel, or if the driver operates the accelerator pedal. If the steering wheel as well as the accelerator pedal part of the

Assumption component of the user interface, preferably the operation is sufficient only one of the two control elements for canceling the assumption.

It is advantageous if the driving system supports various driving functions for automated driving. The various driving functions can, for example, by their degree of automation (bsw.

assisted driving, semi-automated driving or highly automated driving) and / or by their automation direction (automation of the longitudinal guidance versus automation of the lateral guidance). The driving functions can be alternative driving functions or driving functions that can be combined with one another.

It can be provided that the input component of

User interface for each of these driving functions each has its own associated control element to notify the driver-side request for activating the driving function associated with the driving function to the driving system. But it is advantageous if instead the

Input component a common for the various driving functions control element for signaling the driver's desire for includes automated driving. The control element can be used to express the basic desire to activate the automation by the driver to the driving system (ie the desire to activate any of the various driving functions).

The availability of the individual driving functions is checked by the driving system (for example, after actuation of the common operating element or even before that). After the common control has been operated, in

Dependency of the availability check on one or more driving functions offered to the driver. For example, the individual driving functions are offered depending on their respective availability on the output component, in particular can be provided to offer all available driving functions (possibly limited to a maximum number of offered driving functions) It can be provided that determines which driving function below the then available Driving functions has the highest level of automation, with (especially only) the available driving function with the highest possible

Automation level is offered.

When this common control has been activated, it does

Vehicle, for example, proposals for which driving functions for automated driving in the current driving situation are available and offers this to the driver for activation. It can be provided that all available driving functions are offered to the driver or only a maximum number of available driving functions are offered (for example the three available driving functions with the highest possible degree of automation). Alternatively, it may be provided that the driving function with the highest possible degree of automation is determined below the available driving functions and this Driving function is offered with the highest possible degree of automation.

The offer may, for example, in an optical signaling on a display, in particular screen or a head-up display, in an acoustic signaling (eg, a simple beep or a

Speech output) and / or haptic signaling (eg via the steering wheel or over the seat). One or more immediately available driving functions are preferably immediately after the operation of the operating element on the

Output component offered. If one or more further driving functions become available later, these are also offered via the output component, for example.

Within the scope of the offer of the respective driving function, the driver preferably receives an indication via the output component in each case of the acceptance treatment to be undertaken for accepting the respective driving function

Function bid.

The driver can accept the respective offer, in the case of a visual offer z. B. with a cursor on the screen and a control select the offer. Preferably, the steering wheel and / or a foot pedal (especially accelerator pedal) are used to accept the offer (eg, by releasing the steering wheel and / or foot pedal). It would also be conceivable, of course, for a driver-side voice input to accept the offer. If the driver no longer desires automation, for example, he actuates the common operating element. Another aspect of the invention relates to a method for activating a driving function for automated driving for a motor vehicle, comprising the steps of: - Receiving a driver-side request for activating a driving function for automated driving;

- at least as long as the availability of the driving function for

to test automated driving until it is determined that the

Driving function for automated driving is finally available;

- After receiving the driver's request for

Activating, offering the driving function for automated driving to the driver after determining the availability of the driving function for automated driving;

Determination of a driver - side acceptance of the offer of

in response to determining the driver-side acceptance of the offer of the driving function, activating the driving function for automated driving.

The above statements on the driving system according to the invention according to the first aspect of the invention also apply correspondingly to the method according to the invention for activating a driving function according to the second aspect of the invention. At this point and in the

Claims not explicitly described advantageous

Embodiments of the method according to the invention for activating a driving function correspond to the advantageous embodiments of the driving system according to the invention described above or described in the claims.

The invention will be described below with reference to an embodiment with the aid of the accompanying drawings. 1 shows an embodiment of a user interface for a

inventive driving system for automated driving; and Fig. 2 is an exemplary flowchart for activating the driving function for automated driving.

1 shows an exemplary embodiment of a user interface 10 for a driving system according to the invention for activating a driving function for automated driving. The driving function can be an automated driving with any degree of automation and any application (eg permanent driving on the motorway or parking or parking). In the following example, it is assumed that this is a highly automated driving (HAF) with automated longitudinal and transverse guidance (Level 3 according to SAE). For example, the HAF driving function is essentially only available on motorways and optionally on motorway-like roads. The user interface 10 comprises a preferably arranged on the steering wheel control button 1 (activation switch), which serves to signal the driver-side request for activating the driving function (here: HAF) the driving system. The control button can be a mechanical button or a sensor button (eg a virtual button on a touch screen). Preferably, the operation key 1 is backlit and indicates whether the operation key 1 has been operated or not. The luminous color of the control button 1 may correspond to the luminous color of the steering wheel display 4 discussed below. Furthermore, the user interface 10 includes a screen display 2, for example in the instrument cluster or as a head-up display. By means of the screen display 2, the driver is informed about the state of the driving system. On the screen 2, the driver can also

Driving function (here: HAF) are offered according to their availability.

Furthermore, a light indicator integrated in the steering wheel rim 4 is preferably provided, via which the driver is informed about the state of the driving system. About the steering wheel display 4, the driver can also Driving function (here: HAF) are offered according to their availability. The steering wheel display 4 extends over all, for example

Angular ranges of the steering wheel 3 as a closed ring. The

Steering wheel display 4 preferably comprises individual light segments, which can be controlled separately, to let the steering wheel 3 light up either as a closed light ring or only in a left and right area of the steering wheel rim.

The steering wheel has a sensor for hands-on detection, with which it is determined whether the driver touches the steering wheel 4 or not.

Furthermore, the user interface 10 comprises an acceptance component, via which the driver can accept the offer for activating the driving function (here HAF). This assumption component in this example comprises the steering wheel 3 of the vehicle and preferably also the accelerator pedal of the vehicle (not shown).

In Fig. 1, between five states 1 - 5 of the driving system

2, which will be explained below in connection with the flowchart in FIG.

In the initial state 1, the drive function to be activated is still deactivated. The control button 1 for signaling the activation request has not yet been operated by the driver. The control button 1 signals this by the control button 1, for example, not lit (a non-luminous

Operating button is shown hatched in Fig. 1). The steering wheel display 4 indicates that the driving function (here HAF) is not active by this

for example, not lit (the non-illuminated steering wheel display 4 is shown hatched in Fig. 1).

The initial state 1 in FIG. 1 corresponds to the query 100 in FIG. 2, in which it is repeatedly checked whether the operating button 1 has been actuated. As soon as it has been established that the control button 1 has been actuated and the driver's request to activate the driving function (here HAF) has been accepted, the driving system changes to state 2 (see step 1 10). The control button 1 now lights up. In state 2, the driver is informed via the screen display 2 that the driving function (here: HAF) is activated when the driving function is available. In state 2, the availability of the drive function is checked until it is determined that the drive function is available (see query 120).

The availability of the HAF driving function may depend on one or more availability factors. Exemplary availability factors may be: the current vehicle speed (is the speed too high?),

- the current road type (is a motorway or possibly a

highway-like street?),

- the traffic density (is the traffic density too high?),

- existence of recognized lane markings,

- Having a sufficiently fast communication connection to a backend server and / or

- the release of a section for highly automated driving.

If it has been determined that the driving function is available for automated driving, the user interface 10 changes to state 3 (see step 130). It is advantageous that in the event that the driving function is immediately available after pressing the control button 1, the system is not first in the State 2 changes and then changes to state 3, but changes directly to state 3 (not shown).

In state 3, the driver is now offered the now available driving function via the user interface 10. This is done on the one hand via the output on the screen display 2. It is signaled in the context of the function offer on the screen display 2 that the driving function for

automated driving is now available (for example, as a text output "HAF available"), and an indication to the driver of an action to be taken to accept the function indication given

(For example, as a text output "For activation, please release the steering wheel"). Furthermore, the range of functions to automate driving through

Lights the steering wheel display 4 signals, for example, in green. In this case, the steering wheel display preferably illuminates only in a left and a right region of the steering wheel rim (see the non-hatched areas of the steering wheel display 4 in state 3 in FIG. The luminous lateral areas of the steering wheel display 4 comprise the lateral areas of the steering wheel rim, where the driver typically holds the steering wheel with both hands. This will prompt the driver to

Activation of the driving function, the steering wheel 3 to let go. Preferably, it is necessary for the driver-side assumption of the functional range to take the foot off the accelerator pedal. This can be done on the

Screen 2 are signaled. The offer can be accepted by the user, who takes his hands off the steering wheel and - if required by the driving system - takes his foot off the accelerator pedal.

By means of the hands-on detection sensor in the steering wheel 3 can be determined whether the driver takes his hands off the steering wheel. If it has been determined in the query 140 that the driver has the

Function has accepted by the driver has released the steering wheel and the accelerator pedal, the driving function HAF is activated (see step 150). The user interface 10 changes to state 4 (see step 160).

In state 4, the steering wheel indicator 4 lights up as a closed light ring, for example in green. As a result, the driver is signaled that the driving function HAF is activated. In addition, a corresponding message is displayed on the screen 2 in text form (eg "HAF activated") or as a graphic symbol.

Subsequently, when it is determined in the inquiry 170 that the driver has withdrawn the release of the steering wheel, for example by detecting, via the hands-on recognition, that the driver has put his hands back on the steering wheel, the driving function HAF is deactivated again (FIG. see step 180) and the user interface 10 returns to state 3 again. A withdrawal of the steering wheel release could alternatively or additionally also be determined if it is determined that the steering wheel 3 is overridden by the driver. For this purpose, for example, the impressed by the driver via the steering wheel 3 hand-steering torque can be compared with a threshold value and when exceeding the

Threshold on a withdrawal of the release of the steering wheel 3 are closed. A deactivation of the driving function HAF and a change to the state 3 preferably also takes place when the driver releases the vehicle

Has decreased the accelerator pedal by pressing the accelerator pedal. For testing, for example, one for the position of the accelerator pedal

characteristic variable (eg the accelerator pedal angle) are compared with a threshold value. Above, the highly automated driving was used in Fig. 1 and 2 as driving function. The embodiment described in connection with FIG. 1 and FIG. 2 can be applied to others as well

Driving functions for automated driving transmitted, for example, have a different level of automation than highly automated driving.

It is advantageous if the driving system supports various driving functions for automated driving. These various driving functions can be, for example, by their degree of automation (bsw.

assisted driving, semi-automated driving or highly automated driving) and / or by their automation direction (automation of the longitudinal guidance versus automation of the lateral guidance). The driving functions can be alternative driving functions or driving functions that can be combined with one another. It can be provided that the

User interface 10 for the various driving functions different the respective driving functions respectively associated controls according to the control button 1 includes so that the driver by pressing the respective control element can notify the driver's request for activating the associated driving function to the driving system. However, it is advantageous if the user interface 10 instead has a control element which is common to the various drive functions (for example a pushbutton corresponding to the push-button 1) for signaling the driver-side request for automated driving. The control element can be used to express the basic desire to activate automation by the driver to the driving system (i.e., the desire to activate any of the various driving functions). The

Availability of the individual driving functions is checked by the driving system. After the common operating element has been actuated, the individual driving functions are offered depending on their respective availability via the output component. As part of the offer of the respective driving function, the driver receives one each via the output component Note about the acceptance treatment to be carried out to accept the respective offer of functions. For example, if both a

Steering assistance function for only automated lateral guidance and HAF is available at a time, this is communicated to the driver including the necessary acceptance treatment. The driver can, for example, by releasing the steering wheel an available

Activate the steering assist function or alternatively enable available HAF by releasing the steering wheel and the accelerator pedal. Alternatively it can be provided that the driving function below the available driving functions is determined, the highest degree of automation. Only this driving function is then offered to the driver.
