Definitions
- the invention relates to a method for operating a driver assistance device of a motor vehicle, wherein the driver assistance device can be operated in an automatic drive mode and in a manual drive mode.
- control signals are output to at least a steering device of the motor vehicle by means of the driver assistance device in order to autonomously control a steering angle of the motor vehicle by the driver assistance device.
- the steering angle can be manually controlled by a driver by operating a steering wheel of the motor vehicle.
- the invention relates to a motor vehicle with a driver assistance device formed for
- Driver assistance devices for automatically driving a motor vehicle are already known from the prior art. Therein, it is basically differentiated between fully automatic driver assistance devices on the one hand and semi-automatic driver assistance devices on the other hand.
- Semi-automatic driver assistance devices only assume the transverse guidance of the motor vehicle by automatically controlling the steering angle of the motor vehicle by means of the driver assistance device.
- fully automatic driver assistance devices additionally control the drive train of the motor vehicle and thus also assume the longitudinal guidance of the motor vehicle, i.e. the acceleration and the deceleration.
- the interest is directed to an at least semi-autonomous driver assistance device, which outputs control signals at least to a steering device of the motor vehicle in the automatic drive mode in order to automatically control the steering angle.
- the driver assistance device can also be a fully automatic device, which additionally outputs corresponding control signals to a drive train of the motor vehicle. Therefore, the term "autonomous” can presently include both "semi-autonomous" and "fully automatic”.
- automatic parking assistance systems which assist the driver in parking the motor vehicle.
- These driver assistance systems usually calculate a parking trajectory, along which the motor vehicle can be parked into a previously detected parking space without collision.
- the driver assistance device then autonomously controls the motor vehicle into the parking space according to the pre- calculated parking trajectory.
- systems are also known, which serve for automatically driving the motor vehicle in preset road situations or driving situations. For example, it is already prior art to automatically drive a motor vehicle in a congestion or else in a so-called convoy travel.
- Such driver assistance devices overall pursue a common aim of providing the possibility to the driver of the automobile of relaxing during travel and for example using diverse multimedia systems.
- the driver himself can also assume the control over his vehicle anytime, as it is for example described in the documents US 2010/0228417, DE 10 201 1 013 023 A1 as well as US 2012 089 294.
- These printed matters propose various methods, how the driver can again assume the control over his vehicle.
- the steering wheel has to be operated by the driver.
- a motor vehicle is automatically driven by means of a driver assistance device, thus, it is required in certain events to pass the control over the vehicle again to the driver. This is for example required if a risk of collision is detected or else if the environmental conditions fast change and for example rain is detected.
- the communication between the driver assistance device and the driver has proven problematic in such situations. If the control over the vehicle is again to be passed to the driver, this is to be correspondingly signaled to the driver, namely such that the driver is able to particularly fast and reliably conceive or appreciate the intent of the driver assistance device to surrender the control over the motor vehicle.
- a driver assistance device for automatically driving a motor vehicle is known from the printed matter DE 10 201 1 1 12 577 A1 . Therein, by means of a lighting device, the direction is indicated, in which the motor vehicle moves in the current automatic drive maneuver.
- a method according to the invention serves for operating a driver assistance device of a motor vehicle, which is switched between an automatic drive mode and a manual drive mode.
- control signals are output to at least a steering device of the motor vehicle by means of the driver assistance device, and hereby, a steering angle of the motor vehicle is autonomously controlled by the driver assistance device.
- control signals can also be output to a drive train in order to also automatically control the longitudinal guidance of the motor vehicle.
- the steering angle is manually controlled by the driver himself by operating a steering wheel of the motor vehicle.
- a moving light is generated along a predetermined lighting path in a movement direction associated with the switching direction by means of a lighting device.
- the effect according to the invention is achieved in that upon switching the driver assistance device from the one drive mode into the other drive mode, a plurality of sectors of a preset path disposed one behind the other are consecutively illuminated in a preset movement direction such that the impression of a traveling light (moving light) is generated.
- the lighting path, along which the moving light is generated can be disposed on the steering wheel in certain areas and outside of the steering wheel in certain areas such that light animation is provided, in which the impression is generated that the light moves from the steering wheel towards the outside of the steering wheel or in the inverse direction.
- the movement direction of the moving light is dependent on the switching direction of the driver assistance device, i.e.
- the lighting device includes a first lighting unit disposed on the steering wheel and/or a second lighting unit disposed outside of the steering wheel each having a plurality of lighting elements disposed one behind the other such that the moving light is generated by means of the first and/or the second lighting unit.
- the generation of the moving light is performed such that the plurality of lighting elements of the first and/or second lighting unit disposed distributed along the lighting path one behind the other are consecutively activated in order to animate the movement of the light.
- the first and/or the second lighting unit can therein each be provided in the form of a light strip or a lighting string, which includes multiple lighting elements disposed next to each other, which are consecutively activated for generating the moving light.
- one light bar can be disposed on the steering wheel, while the other light bar can be disposed outside of the steering wheel.
- the moving light is generated with the aid of a movable projector, in particular a laser projector. Therein, the light generated by means of the projector is moved along the preset - and imagined - lighting path.
- the moving light is generated along a lighting path disposed on the steering wheel and/or outside of the steering wheel, in particular on the steering wheel in certain areas and outside of the steering wheel in certain areas.
- the mode change can be particularly effectively signaled.
- an area of the lighting path is disposed on an interior trim part of the motor vehicle, namely in particular on a dashboard and/or on a vehicle door.
- a lighting unit disposed on the interior trim part is used as the second lighting unit.
- this area of the lighting path can extend in vehicle transverse direction over the predominant width area - in particular also over the entire width - of the dashboard immediately below the windscreen.
- the moving light upon switching the driver assistance device from the manual drive mode into the automatic drive mode, the moving light can be generated in a first movement direction.
- the moving light is preferably moved from outside of the steering wheel (for example from the dashboard) towards the steering wheel, i.e. in particular from the mentioned second lighting unit towards the first lighting unit.
- animation is provided, in which the light is transmitted to the steering wheel, whereby it is signaled that the driver assistance device assumes the control over the motor vehicle.
- the moving light upon switching the driver assistance device from the automatic drive mode into the manual drive mode, the moving light is moved in a second movement direction opposite to the first movement direction.
- the moving light upon switching the driver assistance device from the automatic into the manual drive mode, the moving light is generated from the steering wheel towards the outside of the steering wheel, i.e. in particular towards the mentioned interior trim part. If the above mentioned lighting units are employed, thus, the moving light is generated from the first lighting unit towards the second lighting unit.
- the impression is generated that the light moves away from the steering wheel.
- the impression is conveyed to the driver as if the automatic control of the driver assistance device over the motor vehicle would be withdrawn, whereby the driver is caused to assume himself the control over the motor vehicle.
- a transition mode is activated, in which it is checked by means of the driver assistance device whether or not the driver operates the steering wheel. If operation of the steering wheel is detected, the manual drive mode is activated. In contrast, if operation of the steering wheel is not detected, thus, the driver assistance device can continue to automatically drive the motor vehicle. In this
- the moving light is generated in the transition mode. Especially in such a transition mode, it is particularly important to be able to direct the attention of the driver as fast as possible again to the control of the motor vehicle.
- the activation of the transition mode is preferably effected autonomously by means of a control device of the driver assistance device.
- the activation of the transition mode can for example be effected depending on a degree of risk, which is determined by means of the control device depending on sensor data of a sensor device of the motor vehicle.
- the transition mode can also be activated if a preset time since the activation of the automatic drive mode has elapsed.
- the transition mode can be activated if preset environmental conditions are detected such as for example rain or the like.
- light signals of a first type different from the moving light can be output from the moving light by means of the lighting device, by which the activation of the manual drive mode and thus assumption of the vehicle control by the driver is signaled.
- the successful assumption of the vehicle control by the driver can for example be signaled by corresponding coloring of the light signals such as for example by blue light.
- the first lighting unit disposed on the steering wheel is controlled for generating these light signals.
- light signals of a second type can be output by means of the lighting device, by which the driver is requested to assume the vehicle drive.
- These light signals can for example have a red coloring in order to reliably make the driver aware of the change into the manual drive mode.
- these light signals can be output by means of the first lighting unit, which is disposed on the steering wheel.
- light signals of a third type can be generated by means of the lighting device, by which the activated automatic drive mode is optically signaled.
- These light signals can for example have a green color and thus signal that the automatic drive mode is activated at the current time and thus the driver assistance device has the control over the motor vehicle.
- the above mentioned light signals of the first type and/or the second type and/or the third type can differ from each other in their coloring and/or in their flash frequency. Thereby, light signals different from each other can be generated, which also can be differently perceived by the driver.
- control signals can also be output to a drive train in order to also automatically control the longitudinal guidance of the motor vehicle. If also the longitudinal guidance of the motor vehicle is controlled automatically, then the transition from the manual drive mode into the automatic drive mode and/or the transition from the automatic drive mode into the manual drive mode can be signalized by means of lighting elements which are arranged on at least one pedal of the motor vehicle and/or in a bottom region of the steering wheel.
- the invention relates to a motor vehicle with a driver assistance device for autonomously driving a motor vehicle, wherein the driver assistance device is switchable between an automatic drive mode and a manual drive mode and includes a control device, which outputs control signals at least to a steering device of the motor vehicle in the automatic drive mode and hereby autonomously controls a steering angle of the motor vehicle, and wherein the steering angle can be manually controlled by a driver by operating a steering wheel in the manual drive mode.
- the driver assistance device includes a lighting device, and the control device is adapted to control the lighting device upon switching the driver assistance device at least in one switching direction from one of the drive modes into the other drive mode for generating a moving light along a lighting path in a movement direction associated with the switching direction.

- control device 3 receives sensor data from a sensor device 10, which may include a plurality of sensors.
- the sensor device 10 can include
- the sensor device 10 can also include sensors serving for detecting current environmental conditions in the environment of the motor vehicle 1 .
- it can be a rain sensor.
- the driver assistance device 2 can be switched into an automatic drive mode such that an autopilot is virtually activated.
- the control device 3 controls at least the steering angle and thus the transverse guidance of the motor vehicle 1 .
- This automatic drive mode can also again be deactivated by means of the control device 3 in autonomous manner and thus independently of the driver if a preset criterion is satisfied.
- This criterion can for example involve that a great degree of risk with respect to a collision with an obstacle and/or rain is detected based on the sensor data and/or a preset period of time since activation of the automatic drive mode has elapsed.
- a transition mode is activated, in which the control over the vehicle drive is to be passed to the driver.
- the control device 3 examines whether or not the driver operates the steering wheel 7 and thus assumes the control over the motor vehicle 1 . For this purpose, it can for example be examined if the steering wheel 7 is turned by the driver himself. Additionally or alternatively, touch sensors can also be disposed on the steering wheel 7, which are able to detect a touch of the steering wheel 7.

- the motor vehicle 1 has a windscreen 12, which is disposed in front of the steering wheel 7 in direction of travel. Between the driver's seat and the passenger seat, there is a center console 13 with an infotainment system 14. An instrument cluster 15 is disposed between the windscreen 12 and the steering wheel 7.
- the lighting device 4 includes a first lighting unit 16 as well as a second lighting unit 17 in the embodiment.
- Both lighting units 16, 17 are formed in the form of a light bar and can each include a plurality of individual lighting elements, which are disposed next to each other.
- the first lighting unit 16 is disposed on the steering wheel 7 and arcuately formed. Therein, the lighting unit 16 is disposed on a steering wheel rim 18, namely in the upper region of the steering wheel rim 18. Therein, the elongated configured lighting unit 16 extends substantially over half of the circumference of the steering wheel rim 18.
- the second lighting unit 17 is also elongated configured and disposed on a dashboard 19, namely immediately below the windscreen 12.
- the second lighting unit 17 also surrounds the instrument cluster 15 in certain areas such that the driver perceives the two lighting units 16, 17 substantially as one common lighting unit. In addition, the second lighting unit 17 extends in vehicle transverse direction over the predominant width region of the motor vehicle 1 .
- the two lighting units 16, 17 define a lighting path 20, along which a moving light is generated by means of the control device 3.
- At least the first lighting unit 16 can additionally be operated in various colors, in particular green, blue and red.
- the driver assistance device 2 is in the automatic drive mode, thus, only the first lighting unit 16 is activated. Therein, the second lighting unit 17 is deactivated.
- the first lighting unit 16 In the automatic drive mode, the first lighting unit 16 generates light signals, by which the activated automatic drive mode is optically signaled. Therein, the first lighting unit 16 can for example generate green light. This green light then signals that the automatic drive mode is activated.
- the first lighting unit 16 generates a flashing light.
- the second lighting unit 17 is also activated, and the two lighting units 16, 17 are controlled by means of the control device 3 such that the mentioned moving light is generated along the lighting path 20 according to the arrow direction 22 from the steering wheel 7 towards the dashboard 19 and thus from the first lighting unit 16 towards the second lighting unit 17.
- the impression is generated that the light moves from the first lighting unit 16 towards the second lighting unit 17.
- light signals are generated by means of the first lighting unit 16, which signal this.
- blue light is generated by means of the lighting unit 16.
- These blue light signals can then for example be maintained for a preset period of time, and after elapse of this period of time, the lighting device 4 can be again deactivated.
- light signals are output by means of the lighting unit 16, which request the driver to assume the control over the motor vehicle 1 .
- These light signals can for example be provided in the form of a red light such that red light is generated by means of the first lighting unit 16.
- Light signals of a second type they are preferably provided in the form of a red light, by which the driver is requested to assume the vehicle drive if a preset time interval has elapsed after activation of the transition mode;
- Light signals of a third type they are realized by green light, which is output by means of the first lighting unit 16 in the activated automatic drive mode, if the control device 3 has the control over the motor vehicle 1 .
- a moving light is generated from the steering wheel 7 towards the dashboard 19 if the transition mode is activated.
- a corresponding moving light is generated in the inverse movement direction 21 from the second lighting unit 17 towards the first lighting unit 16. This moving light towards the steering wheel 7 then signals that the control device 3 assumes the control over the motor vehicle 1 .
