Definitions
- the invention relates to methods for operating a driver assistance device of a motor vehicle.
- sensor data of a surrounding area of the motor vehicle are detected.
- At least one target vehicle is located in the surrounding area.
- the target vehicle is located in front of the motor vehicle and on the same lane as the motor vehicle.
- the invention relates to a driver assistance device having an evaluation unit which is designed to execute a corresponding method.
- the invention also relates to a motor vehicle with a corresponding driver assistance device.
- Methods for operating a driver assistance device of a motor vehicle are known from the prior art. For example, it is known that a future overtaking path of a motor vehicle is calculated based on environmental sensor data or map data, and the overtaking path or a hint based thereon is output to assist a driver in an overtaking operation.
- a driver assistance device of a motor vehicle is operated. The following steps are carried out:
- Motor vehicle in which at least one target vehicle is located, which is, in particular in the direction of travel of the motor vehicle, in front of the motor vehicle and which is located in the same lane as the motor vehicle;
- Reading in driver-class-specific overtaking information which describes a passing habit of the driver based on the driver class assigned to the overtaking information
- the invention is based on the finding that the over ⁇ holvorgang by the driver class specific overtaking information, ie by taking into account the driver's individual driving style, can be performed safely.
- the passing information for the different driver classes is available in different ways.
- Overtaking information describes the overtaking habit of the driver or his driving habit in overtaking maneuvers.
- the driver is in turn assigned to the driver class.
- the driver class can For example, include only the driver or multiple drivers and thus serve as a generalization of the overtaking information for overtaking habits of multiple drivers.
- the overtaking information can be present as a, in particular unitless, number vector or one, in particular unitless, number matrix with one or more dimensions.
- the overtaking information is then compared with the overtaking information associated with the reference control signals. In particular, the reference control signal with the most similar overtaking information is selected.
- This preference for the operation of the motor vehicle can be represented numerically on the basis of properties described below. These properties, which can also be represented numerically, since they are characterized by parameters or values of states of components of the motor vehicle, are taken as the basis for the machine learning to generate the overtaking information.
- the overtaking information can be present in particular as a classifier for selecting the control signal.
- the overtaking information of the reference control signals provides various classes to which the driver is assigned on the basis of the comparison.
- each class provides a different control signal.
- one class provides the override control signal with maximum possible acceleration
- another class provides, for example, the control signal which only passes with half maximum possible acceleration. It detects the surrounding area of the motor vehicle and the sensor data is provided.
- the surrounding area can be detected for example with a variety of environmental sensors of the motor vehicle, for example a camera, a radar sensor, a lidar sensor, a laser scanner, an ultrasonic sensor or a combination of these sensors.
- the target vehicle In front of the motor vehicle is the target vehicle.
- the motor vehicle thus approaches the target vehicle.
- the motor vehicle is on the same lane as the goal ⁇ vehicle, so the vehicle has to overtake the target vehicle to drive past a speed higher than the target vehicle to the target vehicle.
- the surrounding area is detected.
- the driver By the driver of the motor vehicle the driver be ⁇ write feature is detected.
- the driver can feature game, in ⁇ by an inner space of the motor vehicle camera, an RFID chip (RFID - Radio Frequency Identification) generating key in the vehicle or recorded a fingerprint reader.
- RFID chip RFID - Radio Frequency Identification
- the driver feature may thus be a feature that preferably uniquely identifies the driver.
- the driver attribute assigns the driver to the predetermined driver class. This is done in particular on the basis of a mapping of the driver characteristic to the driver class.
- the Fah ⁇ rerstal alone can have only the driver and does not necessarily contain multiple drivers.
- the assigned driver class is assigned the overtaking information.
- the overtaking information describes the Sprintholge ⁇ habits of the driver or the overtaking habits of the driver class, which is assigned to the driver.
- the overhauls ⁇ la are preferably of driver class driver class different. Thus, with respect to exhibit an overtaking maneuver on ⁇ example riskier driver a driver class, while another driver class having less risky drivers.
- the overtaking information is read, for example, from a memory of the motor vehicle or a vehicle-external device.
- the control signal of the driver assistance device is selected.
- Rate ⁇ be indicated, for example, a risk or risk International ⁇ probability for the overtaking operation is determined. Evaluating, however, can also mean that it is determined whether the overtaking process can be carried out safely or whether the overtaking process can not be carried out safely.
- This review may, for example, methods of data analysis, movement of such data ⁇ processing, data transformation, data modeling as well as with methods of machine learning and artificial intelligence, such as neural networks, SVM methods (SVM - support vector machine), deep learning, ANN (ANN - k-nearest-neighbor), regression or the like.
- the control signal is output by the driver assistance device.
- a visual and / or acoustic and / or haptic indication can be triggered by the control signal.
- an at least semi-autonomous or piloted performed overtaking process of the motor vehicle can be triggered.
- At least semi-autonomously ⁇ that the steering of the motor vehicle and / or the acceleration of the motor vehicle automatically means in this context that is, substantially without the influence of a human driver, is carried out.
- the overtaking information is generated based on training data with at least one of the following characterizing the driver.
- the training data thus have at least one of the properties.
- the property can be present, for example, as a travel speed relative to the regulation speed, as a safety distance when reclosing after the overtaking process has taken place, or as an exiting distance to the target vehicle before the overtaking process has taken place.
- the property can also be present in particular by an off ⁇ shear angle of the vehicle at the beginning of overtaking.
- the Ausscherwinkel is described with which angle to the lane longitudinal axis, the motor vehicle performs the lateral movement with respect to the lane at the beginning of the overtaking process.
- the regulation speed can be present, for example, as a directional speed or as a legal speed limit.
- the overtaking information is then generated, for example, by machine learning with the training data.
- the overtaking information is then assigned to a driver class or the driver class is created by the respective overtaking information.
- the steering- signal is then selected depending on the habits of the driver.
- control signal can also be selected according to whether the driver would like to have a large safety margin during re-scissors after a successful overtaking or a smaller safety distance to the target vehicle after a successful overtaking ⁇ process. So whether the safety distance exceeds or falls below a distance limit.
- the distance may be in the unit m, for example. So many drivers would like with a large safety margin, so play as Reeve at ⁇ several car lengths ahead of the target vehicle again and some other drivers, for example, it is sufficient even if the safety distance is the length of a vehicle.
- the driver is then assigned, for example, a first class of overtaking habits and in the second case a second class.
- a first reference control signal is preferably present, and in the second class, a second reference control signal, which differs from the first reference control signal, is preferably present.
- the Ausscherentfernung to the target vehicle can be present as the property.
- the Ausscherentfernung to the target vehicle indicates how far ahead of the target vehicle, the motor vehicle leaves the lane side or with an at least partially lateral movement.
- the acceleration profile can also serve as a property.
- the acceleration profile describes with which acceleration values the motor vehicle is operated in the different phases of the overtaking process.
- the motor vehicle can be accelerated more sharply at the beginning of the overtaking process than at the end of the acceleration process, or vice versa, or else the motor vehicle is only in the In the middle of the overtaking process, it accelerates sharply, while at the beginning of the overtaking process and at the end of the overtaking process it is only accelerated to a lesser extent than in the middle phase.
- the property may also be the acceleration behavior.
- the acceleration behavior can describe, for example, how the driver accelerates the motor vehicle.
- the accelerator pedal can be pushed completely through or only partially pushed through. This corresponds to different degrees of utilization of the power reserve.
- a shift to a lower gear prior to or during the overtaking process for example, be assigned to a first class, while maintaining the gear before or during the over ⁇ holvorgangs a second class is assigned.
- the Sprint ⁇ linformation is generated depending on a current weather condition and / or a current time and / or a current day of the week.
- the overtaking information can also be generated depending on a current traffic density and / or a current road category.
- the current weather condition for example, it can be specified whether it is raining, whether it is snowing, what outside temperatures are present, and then again how the overtaking habit of the driver is dependent on the weather condition. For example, there are drivers who are on wet roads or ice-covered ones Reward less frequently than they would on dry and / or unfrozen lanes.
- the overtaking information can be generated or trained, for example, depending on the current time. For example, there are drivers who drive in the morning on the way to work and / or in the evening on the way home from work more risky and thus overtake more often than is the case for example during working hours. Also, for example, the reverse case may occur, so that is overtaken more often during working hours, because then important dates must be adhered to. It can also be provided that the overtaking information is generated depending on the current day of the week. For example, the driver may overtake you more often on weekdays than on holidays or on public holidays
- the traffic volume can be used as the property for generating the passing information. For example, there are drivers who overtake only with low traffic, since the overtaking situation is then usually clearer. But it can also be the other way round, so that it is attempted to get to the destination more quickly, especially when traffic is high. Even with the street category read the property, the overtaking information can be generated.
- Road category classifies the road within a road network in terms of road construction load, design standard or usage constraint. For example, a driver overhauls federal roads differently than he overtakes on county or municipal roads.
- a current operating parameter of the motor vehicle is detected and an overtaking intention of the driver is recognized on the basis of the operating parameter and the overtaking information and the control signal is dependent is selected from the recognized overtaking intent.
- the Be ⁇ operating parameters can match, for example, with the properties of the training data.
- a specific distance behavior or a specific acceleration behavior can be detected by the operating parameter, which has a similarity with the overtaking information.
- the operating parameter can be compared with the overtaking information and then classified as similar or dissimilar, for example, based on the comparison. If the operating parameter with the overtaking information is estimated to be similar, then it can then be used, for example, to trace back to the presence of the driver's intention to overtake.
- the control signal to the driver that the overtaking at a certain distance without risk would be possible or that the present overtaking option should be used, as in the next travel section no overtaking is available.
- a currently physio logically ⁇ recognizable indicator of the driver is detected and the flag is compared with a plurality of reference indicator, wherein a overtake the driver is detected based on the comparison.
- the physiologically recognizable mark becomes a body of the driver
- a degree of nervousness and / or an eye movement and / or a volume of a noise emitted by the driver and / or a semantic meaning of a noise emitted by the driver is detected as the currently physiologically recognizable indicator.
- the degree of nervousness may for example be determined based on welding ⁇ formation on one end of the driver or welding surfaces on the palms of the driver.
- the sweat formation can be detected, for example, with sensors of the motor vehicle, for example a camera.
- the given by the driver from ⁇ noise can for example be a statement or a blow to an object in the vehicle.
- the noise is a driver's statement, for example, the semantic meaning of the phrase can be detected by a speech recognition program. For example, if the driver is shouting or cursing, this may be taken as an indication of overtaking intent.
- the control signal in turn can be selected depending on the intention to overtake. For example, a warning can be issued to the driver if the intention to overtake is recognized, but overtaking, taking into account his overtaking habit, is not possible. In turn, the motor vehicle can be operated more safely.
- an individual overtaking path is determined for the overtaking procedure with respect to the target vehicle. So it may be, for example, that is known by the overtaking information that the driver usually reconditioned leisurely while not exploiting the power reserves of the motor vehicle. For example, the driver can then be given no indication of an imminent overtaking opportunity if the exploitation of the power reserve in this case is a prerequisite for the success of the overtaking process is. A driver who exploits the power reserves of the motor vehicle and is fundamentally more willing to take risks, the overtaking proposal can be issued in this case.
- the physiologically recognizable indicator recognizes that the driver is in a state which is either particularly relaxed and therefore more likely to assume a slow overtaking maneuver or the driver is particularly tense and excited, which is why Driver no overtaking proposal is issued because the driver is a deliberate procedure just not dared.
- the motor vehicle can thus in turn be operated safely.
- the Sprint ⁇ linformation is adjusted depending on a current vehicle guidance of the driver, in particular by an online training, during operation of the motor vehicle.
- the driver's current vehicle guidance in particular including the operating parameters of the motor vehicle, is detected and the overtaking information is adjusted.
- the current vehicle guidance of the driver can then also be described, for example, with the properties of the training data, which are used to generate the overtaking information.
- Overtaking information the overtaking information can be kept up to date and accurate. For example, the overhaul habit of a driver may change over time. For example, the driver can get older and therefore more relaxed or less willing to take risks in certain overtaking situations.
- the method can also be carried out with a few initial training data, since the
- Online training describes a method of machine learning in which a classifier is adjusted during operational operation.
- the classifier is thus trained with training examples, which it has previously assigned to the classes themselves.
- initial training data are usually assigned to the classes manually, ie by people.
- the overtaking information adapted during operation of the motor vehicle is transmitted to at least one device external of the motor vehicle.
- the vehicle-external device can be formed in ⁇ example, as an external server or multiple external server.
- the adapted overtaking information can thus be transmitted, for example, into a so-called computer cloud, that is, into a distributed computer network.
- the device can be stationary, distributed or centrally available.
- a model underlying the overtaking information can be adapted by the adapted overtaking information. This is also advantageous as data backup of the overtaking information.
- the overtaking information can be deleted, for example, from a memory of the motor vehicle or even not exist in a new car and be restored by the backup of overtaking information.
- a Matterholönkeits fundamental or warning ⁇ indicative for the overtaking the motor vehicle of the Target vehicle is output by the driver assistance device.
- a visual and / or acoustic and / or haptic indication to the driver of the motor vehicle are issued that the overtaking is possible.
- the driver of the motor vehicle for example, visually and / or acoustically and / or haptically, issued that the overtaking process, for example, just for a certain distance or a certain period of time is not feasible or can only be carried out in the manner that the Overtaking the
- the overtaking ⁇ process of the motor vehicle with respect to the target vehicle based on the control signal is performed at least semi-autonomously.
- semiautonomous overtaking for example, a steering intervention and / or an acceleration or braking intervention can take place.
- the driver of the motor vehicle is therefore moved so well when at least se ⁇ miautonomen overtaking the vehicle that its Kochholge stickheit is considered.
- the overtaking process can also be performed fully autonomously, so that the driver is present only as a spectator or monitor in the vehicle. Also in this case, the driver will feel more comfortable when the motor vehicle behaves when overtaking as he would do it during manual operation of the motor vehicle itself.
