Description

The invention relates to a method and a device for situation-based warning of a driver of a vehicle. Furthermore, the present invention relates to a vehicle having such a device for situation-based warning of a driver.

The steadily growing traffic volume and the associated increased demands on the driver of a vehicle has long been taken into account by various assistance systems which are to assist the driver in dangerous situations (for example an anti-lock braking system, an anti-slip control, Lane Keeping Assist or the like) or to prevent potentially dangerous situations in advance, for example by alerting the driver to a potential hazard.

The method according to the invention and the device according to the invention are explained below on the basis of a vehicle. It should be noted, however, that this focusing is not a limitation of the subject invention, but merely serves to simplify the presentation of the following facts.

From the DE 10 2004 016 808 A1 a signaling device for displaying and / or outputting warning and / or information instructions in vehicles by means of optical and / or acoustic signal sources is shown, wherein on the basis of an available signal, for example from a collision avoidance system, directional information for a vehicle driver related to an event related to a particular object to be made aware of.

From the DE 198 43 564 A1 a warning device for monitoring a distance of a vehicle from an obstacle is known, the at least one sensor for detecting an obstacle, an evaluation and control device for estimating a distance of the vehicle from the obstacle based on an output signal of the sensor and at least one warning signal generator, the Evaluation and the control device for generating a short-range warning signal is controlled when the estimated by the evaluation and control device distance s is smaller than a threshold value S ₁ includes. It is provided that the evaluation and control means comprises means for estimating a collision hazard of a vehicle with the obstacle based on the estimated distance and the speed of the vehicle and that the evaluation and control means controls the warning signal generator to output a far-range warning signal when the estimated distance s is greater than the limit value S ₁ and the assessment gives the presence of a risk of collision.

The DE 199 19 216 A1 relates to an information system in a vehicle having a plurality of information sources for outputting a respectively associated information in the presence of a respectively associated information-generating condition. According to this publication, two or more vehicle guidance information sources of different types are provided, which are coordinated in their information output conflict-free so that at most each time one of these vehicle guidance information is delivered. Alternatively or additionally, a prioritization of vehicle guidance information and non-vehicle guidance information according to a plurality of sequentially processed urgency levels is provided, wherein the vehicle guidance information is assigned a higher priority and the non-vehicle guidance information has a lower urgency.

It is an object of the present invention to provide an advantageous method for situation-based warning of a driver of a vehicle, which is in particular configured to increase driving safety.

This object is achieved by a method for situation-based warning of a driver of a vehicle according to claim 1, a device for situation-based warning of a driver of a vehicle according to claim 12, and a vehicle having such a device for situation-based warning of a driver according to claim 14.

The features of the advantageous embodiments described below can be combined as desired with one another, unless this is expressly excluded. In particular, the features and advantages described in relation to a first aspect of the invention also apply to the further aspects of the invention and their advantageous embodiments, and vice versa.

• (a) Erfassen eines Ist-Werts eines Parameters, insbesondere einer Geschwindigkeit und/oder einer Position, des Fahrzeugs;
• (b) Abgleichen des Ist-Werts mit einem Soll-Wert des Parameters; und
• (c) Ausgeben eines Warnsignals an den Fahrer, wenn der Ist-Wert den Soll-Wert je nach Art des Parameters über- oder unterschreitet,

wobei der Soll-Wert des Parameters unter Berücksichtigung von Ist-Werten anderer Fahrzeuge aus der Vergangenheit dynamisch bestimmt wird. A first aspect of the present invention relates to a method for situation-based warning of a driver of a vehicle, comprising the steps:

• (A) detecting an actual value of a parameter, in particular a speed and / or a position of the vehicle;
• (b) matching the actual value with a desired value of the parameter; and
• (c) outputting a warning signal to the driver if the actual value exceeds or falls below the desired value, depending on the type of parameter,

wherein the target value of the parameter is dynamically determined taking into account actual values of other vehicles from the past.

While in known systems at the level of the web guide, so the steering, accelerating and decelerating, while driving a vehicle only static information for determining the target value are available, the method according to the present invention advantageously relates actual values of other vehicles from the past, in particular on the route section lying ahead, into consideration, whereby, for example, in the case of a "right of way" sign, which is stored as static information, for example in a navigation system, it is determined whether there is a rapid inflection at this point or whether the entry into the priority road may be very slow and careful. In this way, it is possible to warn "correctly", that is, in the amount required but not excessive for the driver. Thus, the driver does not feel bothered by being warned too frequently, and too infrequent warning is avoided, which even increases excessively an accident risk, especially if the driver relies on being warned but not warned. The present method is also advantageous for monitoring the lateral guidance of the vehicle, since in this way not only a distance to a side line is taken into account, but also the driving behavior of preceding vehicles, which are combined into a kind of "ideal line".

A "vehicle" in the context of the present invention is to be understood as meaning, in particular, a land vehicle driven by a motor, that is to say in particular passenger cars, trucks, motorcycles and tractors. The engine may be an electric motor, an internal combustion engine, a hybrid drive system, a fuel cell or the like.

A "situation-based warning" is understood to mean, in particular, that the driver is warned by an optical and / or acoustic and / or haptic signal of a potentially dangerous situation in particular in such a way that the driver still has enough time to respond to this situation , for example by a steering movement, braking, accelerating or the like.

A "parameter" in the sense of the present invention is in particular a characteristic which describes a state of the vehicle, in particular a speed and / or a direction and / or a position.

An "actual value" in the sense of the present invention is in particular the value of a parameter which at least substantially corresponds to the current and / or true value of the parameter and thus at least substantially substantially describes a property of the vehicle at least substantially in the present.

In the sense of the present invention, a "desired value" is to be understood in particular to mean a value which is compared as a threshold value with the actual value of the vehicle in order to provide a rating on the basis of the, in particular relative, ratio of desired value and actual value the driving situation, in particular to decide whether and, if so, which warning signal should be output to the driver.

For the purposes of the present invention, the term "under consideration" means in particular that the actual values of other vehicles from the past can form the sole basis for the dynamic determination of the desired value, but it is still possible if not even preferred, further, in particular static, traffic data, such as the presence of a "right of way" sign or the like, also to be included in the provision.

"Actual values of other vehicles" are to be understood, in particular, as meaning those data which are determined by other vehicles and transmitted directly or indirectly, for example via a server, to the driver's own vehicle. Depending on the configuration of the system and / or the frequency of the route traveled, the considered past may extend in a range of a few seconds, in particular ten seconds, to several days, in particular seven days, and / or defined by a predetermined number of other vehicles be.

A "dynamic determination" in the sense of the present invention is understood in particular to mean a determination which is based not only, in particular not, on static information, such as the presence of a "right of way" sign, but at least essentially continuously changing actual values of other vehicles from the past. In this way, even static danger points, such as construction sites, diversions and / or accidents, with low lead time in the determination of the target value to go without the underlying cause of behavioral change of the other vehicles must be known to carry out the process.

This is particularly advantageous since in this way, in particular at least substantially precisely, it is possible to be warned of potential dangers. The automation of driving functions to highly automated driving can use the actual values of other vehicles from the past. Thus, the behavior of the automated vehicle is much more similar to that of a manually controlled one. Thus, the acceptance of automated driving functions can also increase.

According to an advantageous embodiment of the target value is further determined dynamically taking into account the driver and / or the weather and / or an operating mode of the vehicle.

This is particularly advantageous because in this way the database is expanded in the dynamic determination of the desired value, which can lead to a further improvement in the assessment of whether and, if so, in what form a warning signal is to be output to the driver. With regard to the driver, for example, personal driving habits, a predetermined level of information, information about the attention of the driver can be taken into account. With regard to the weather, temperatures, precipitation, wind and / or brightness can be taken into account. An operating mode of the vehicle is, for example, an Eco mode or a Sport mode.

• (b1) Erfassen eines Ist-Werts aus der Vergangenheit des Parameters von wenigstens zwei weiteren, insbesondere vorausfahrenden, Fahrzeugen, insbesondere Abfragen der Ist-Werte aus der Vergangenheit der wenigstens zwei weiteren, insbesondere vorausfahrenden, Fahrzeuge;
• (b2) Ermitteln eines Kennwerts, insbesondere eines Mittelwerts aus den Ist-Werten der wenigstens zwei weiteren Fahrzeuge; und
• (b3) Ableiten des Soll-Werts für das, insbesondere eigene, Fahrzeug aus dem Kennwert.

According to a further advantageous embodiment, the method further comprises the sub-steps:

• (b1) detecting an actual value from the past of the parameter of at least two further, in particular preceding, vehicles, in particular queries of the actual values from the past of the at least two further, in particular preceding, vehicles;
• (b2) determining a characteristic value, in particular an average value, of the actual values of the at least two further vehicles; and
• (b3) deriving the desired value for the, in particular own, vehicle from the characteristic value.

This is particularly advantageous because in this way the actual values from the past of other vehicles do not necessarily have to be transmitted to the own vehicle, but it is sufficient to transmit a characteristic value characterizing these actual values, such as an average value from the actual value. Values of the at least two other vehicles. It goes without saying that in determining a characteristic value not only the arithmetic mean can be used, but also other calculation methods, such as the median, an interval, a center of gravity or the like. In a preferred embodiment, this is dependent on the distribution of the underlying actual values of the other vehicles from the past.

According to a further advantageous embodiment, the steps b1 and b2 are executed on a server and the determined characteristic values are transmitted to this for deriving the desired value for the, in particular own, vehicle. According to an alternative embodiment, the step b1 is executed on a server which transmits the detected actual values for carrying out the steps b2 and b3 to the, in particular own, vehicle. According to a further alternative embodiment, the steps b1, b2 and b3 are executed on a server and the derived target value for the, in particular own, vehicle is transmitted to just this.

According to a further alternative embodiment, in step b1, the actual values from the past are recorded directly by the, in particular own, vehicle of at least two further vehicles, in particular by transferring these actual values from the other vehicles to the, in particular, own vehicle, in particular without an intermediary server, so that the steps b1, b2 and b3 are executed by the, in particular own, vehicle.

According to a further advantageous embodiment, the step (b1) comprises querying the actual values from the past of the at least two further, in particular preceding, vehicles, in particular from a server.

This is particularly advantageous, since in this way the actual values of the at least two further, in particular preceding, vehicles do not have to be detected by the own vehicle, but data can be used, which preferably already exists or is stored in the respective further vehicles are. This reduces the required sensor cost of, in particular own, vehicle according to one embodiment and thus contributes to a cost-effective implementation of the above-mentioned embodiment.

According to a further advantageous embodiment, the parameter is a vehicle position and the desired value is derived from an ideal line.

An "ideal line" in the sense of the present invention is in particular less an objective, in particular static, defined optimum travel profile of a vehicle, but rather a result of, in particular statistical, evaluation of actual values from the past of at least two other, in particular preceding, vehicles, which can change accordingly dynamically. The "ideal line" according to the invention thus forms the vehicle behavior of other vehicles the same route section, in particular without carrying out an assessment of this average vehicle behavior on the basis of objective criteria and / or correcting it if necessary. This is particularly advantageous when monitoring the lateral guidance, since in this way the existing data are compressed and the data volume to be transmitted to the vehicle, in particular its own vehicle, is reduced. The ideal line in the sense of the present invention is advantageous in comparison to a distance monitoring to a lateral line known from the prior art, since obstacles that are not known on individual route characteristics and / or the static system, for example the navigation system, can be imaged in a timely manner.

According to a further advantageous embodiment, the desired value is derived from a statistical distribution.

This is particularly advantageous, since in this way a reproducible compression of the output data, that is, the actual values from the past of the parameter of at least two other, in particular preceding, vehicles takes place. This database can be evaluated statistically, in particular by determining the underlying distribution form, for example a normal distribution, and then determining these characterizing characteristics, such as an average and / or standard deviation, and deriving the target value for the, in particular, own , Vehicle can be used.

According to a further advantageous embodiment, the warning signal is output when the actual value leaves a predetermined probability interval.

This is particularly advantageous because in this way a reproducible condition can be specified when a warning signal is to be output and when not. Thus, for example, in the area of the transverse guidance, a warning signal can be output when the driver leaves an interval of 1 sigma around an average, so that a warning signal is output when the driver leaves a route area on which approximately 68% of the one in consideration in other words, as soon as it - in one direction - enters an area in which just about 15% of the other vehicles have moved.

According to a further advantageous embodiment, the desired value is defined sector by sector.

This is particularly advantageous because in this way the amount of data can be further reduced, since for a sector in each case preferably only one desired value for a parameter is determined and predetermined.

According to a further advantageous embodiment, the length of a sector is proportional to the average degree of change of the parameter within the sector.

This is particularly advantageous because in this way the length of a sector is dynamically adjusted, depending on the average degree of change of the parameter within the sector. In other words, the greater the change in the parameter in a preceding stretch of road, for example in the area of a sharp turn, the shorter the sectors in order to be able to adequately warn the driver of the situation in each case.

• (d) Übertragen des Ist-Werts des Parameters des, insbesondere eigenen, Fahrzeugs an einen Server.

According to a further advantageous embodiment, the method further comprises the step:

• (d) transmitting the actual value of the parameter of the, in particular own, vehicle to a server.

This is particularly advantageous since in this way the actual values of the parameter of the vehicle, in particular its own, can also be made available to other vehicles. According to an alternative embodiment, the actual value of the parameter of the, in particular own, vehicle, in particular directly, is transmitted to at least one further vehicle. In this way, if necessary, communication structures can be simplified and data transmission times can be reduced.

According to a further advantageous embodiment, a, in particular driver-specific, tolerance threshold is specified in the determination of the desired value.

This is particularly advantageous because in this way, in particular by the driver, an individual specification can be made which takes into account the personal preferences and / or a degree of fatigue and / or wishes, so as not to use the desired value of the parameter directly in the decision whether a warning signal should be issued to the driver or not, but possibly earlier or later.

• (a) Mittel zum Erfassen eines Ist-Werts eines Parameters des Fahrzeugs;
• (b) Mittel zum Abgleich des Ist-Werts mit einem Soll-Wert des Parameters; und
• (c) Mittel zur Ausgabe eines Warnsignals an den Fahrer, wenn der Ist-Wert den Soll-Wert je nach Art des Parameters über- oder unterschreitet,

wobei der Soll-Wert des Parameters unter Berücksichtigung von Ist-Werten anderer Fahrzeuge aus der Vergangenheit dynamisch bestimmt wird. A second aspect of the present invention relates to a device for situation-based warning of a driver of a vehicle, in particular for carrying out a method of the type described here, comprising:

• (a) means for detecting an actual value of a parameter of the vehicle;
• (b) means for comparing the actual value with a desired value of the parameter; and
• (c) means for outputting a warning signal to the driver if the actual value exceeds or falls below the nominal value, depending on the type of parameter,

wherein the target value of the parameter is dynamically determined taking into account actual values of other vehicles from the past.

According to one embodiment, the means for detecting an actual value of a parameter of the vehicle is adapted to detect an actual value of a parameter of the vehicle, that is, they have the corresponding hardware and / or software technical means, this task to fulfill.

According to one embodiment, the means for balancing the actual value with a desired value of the parameter are adapted to match an actual value with a desired value, that is to say they have the corresponding hardware and / or software technical means to fulfill this task.

According to one embodiment, the means for outputting a warning signal to the driver when the actual value exceeds or falls below the target value according to the type of parameter are adapted to output a warning signal to the driver when the actual value exceeds the target value. Value exceeds or falls below, depending on the nature of the parameter, that is, they have the appropriate hardware and / or software-technical means to perform this task.

For further details and / or advantages, reference is made to the above explanations of the method.

According to an advantageous embodiment of the device, the target value is further determined dynamically taking into account the driver and / or the weather and / or an operating mode of the vehicle.

This is particularly advantageous because in this way the database is expanded in the dynamic determination of the desired value, which can lead to a further improvement in the assessment of whether and, if so, in what form a warning signal should be output to the driver. With regard to the driver, for example, personal driving habits, a predetermined level of information, information about the attention of the driver can be taken into account. With regard to the weather, temperatures, precipitation, wind and / or brightness can be taken into account. An operating mode of the vehicle is, for example, an Eco mode or a Sport mode.

A third aspect of the present invention relates to a vehicle having a situation-based warning device of a driver of the type described herein.

With regard to further embodiments and / or advantages of this aspect of the present invention, reference is made to the above statements regarding the device and / or the method in order to avoid repetition.

Other features, advantages and applications of the invention will become apparent from the following description of an embodiment in conjunction with the figures. It shows:

7 a flowchart of an embodiment of the method according to the invention.

1 shows a schematic plan view of a route with a vehicle according to an embodiment of the present invention in an exemplary driving situation during the course of a winding route. The vehicle F moves in the illustrated situation on a winding road in a sector s ₁ at a speed v _ist . The vehicle F detects the actual value v _{ist of} a parameter, here: a speed of the vehicle. The vehicle F is a target value for the speed v _{soll_1} for the sector 1 s ₁ known. The determination of the desired value V _{soll_1} takes place taking into account actual values of other vehicles from the past. The determination of v _{soll_1} can take place here in the vehicle F itself or in a remote data processing device, for example a server, which then provides the vehicle with the desired value v _{soll_1} . The actual value v _ist is compared with the setpoint value v _{soll_1} . The vehicle F issues a warning signal to the driver when the actual value v _ist exceeds or _{falls below} the nominal value v _{soll_1,} depending on the type of parameter, in this case: exceeds in particular at a speed. However, it is also conceivable that a warning signal is output to the driver when the actual speed v _{ist of} the vehicle F, in particular clearly, below the actual values of other vehicles from the past, since even such a deviation may increase a risk potential Especially when faster vehicles approach from behind.

If the vehicle F exceeds the sector boundary between, for example, the sectors s ₁ and s ₂ , the sector 2 s _{2 is subject to} a possibly changed setpoint speed v _{soll_2} which is reduced in relation to the depicted situation.

A concrete example is given below: In this case, the desired speed v _{soll_1} in sector 1 s _{1 is} 80 km / h, in sector 2 s ₂ v _{soll_2 is} 60 km / h and in sector 3 s ₃ v _{soll_3 is} 50 km / h H. Is for v is a speed of 75 km / _h detected, for example, no warning signal is issued to the driver. Is for v is a speed of 110 km / _h, for example, is detected, then the driver is issued a warning signal, for example via an instrument cluster and / or a head up display and / or haptically and / or acoustically, for example in the form: "Attention Curve, high speed! + 30 km / h ". If a value of 86 km / h is determined for v _, a warning signal can still be dispensed with after execution in accordance with an individual specification of the driver since the actual value is still within a predetermined probability interval derived from the actual values of other vehicles the past, is and thus still "in the normal range" is.

2 shows a schematic plan view of a driving situation in which the vehicle is to turn on a priority road. In this classic "right of way eighth" situation, the vehicle is provided with information about whether it is a clear confluence or rather a confusing confluence via _{v_s_1} and _{v_s_2_2} , since the actual values of the _turbulence in a rather unclear confluence are Other vehicles from the past are less than a clear confluence. Thus, according to an embodiment of the method according to the invention not only information is available that an undifferentiated, "right of way eighth" situation is imminent, but it can also draw conclusions on the quality of the junction and used in the dynamic determination of the target value become.

The method according to an embodiment of the present invention is not limited to "stick out" situations, but may apply to all types of signs that affect the longitudinal dynamics of the vehicle F, such as speed limits, stop signs, location signs, or the like. In particular, an embodiment of the method according to the invention can also be used for traffic lights, wherein in traffic lights with fixed times the respective profiles for "red" or "green" can be loaded situational or, especially in intelligent traffic lights, due to additional vehicle sensors, the traffic light Status are recorded.

The 3a and 3b show a plan view of a roadway with a vehicle, the transverse steering is monitored along a route by a method according to an embodiment of the present invention.

In the p-pos diagram, the respective position pos in the region of a lane is plotted on the x-axis, while the frequency or the probability (probability) p is plotted on the y-axis. Shown is the determined distribution of the vehicle positions of other vehicles from the past in the lane. The diagram thus describes where other vehicles from the past have been located in the area of the depicted roadway according to the illustrated statistical distribution. From this it is derived according to an embodiment of the present invention, whether the vehicle F with its current position pos _is still in a "normal range" of the distribution moves, or in one of the edge areas, which optionally leads to the issuing of a warning signal to the driver.

While in 3a a scenario is shown where the vehicle position _is heading of the vehicle F or the, in particular predicted, distance W _{F is} within a permissible range for which no warning is output, the vehicle position pos _is the vehicle F or the, in particular predicted, distance W _F in 3b in an edge region of the distribution, which according to an embodiment of the present inventive method for outputting a warning signal to the driver, in particular such: "Attention tracking! Steer left! "Leads.

4 shows a schematic plan view of a driving situation on a multi-lane road, wherein the distance of the vehicle is monitored according to an embodiment of the method according to the invention. In multi-lane roads results in a kind of wave profile. According to an advantageous embodiment, the lane change is warned, unless a turn signal is operated.

5 shows a plan view of a further driving situation, which is monitored by means of an embodiment of the method according to the invention. This illustration shows by way of example how the length of a sector is related to the average degree of change of the parameter within the sector. In the present example v _{soll_1 is} 82 km / h, v _{soll_2} 72 km / h, v _{soll_3} 62 km / h, v _{soll_4} 52 km / h, v _{soll_5} 62 km / h, v _{soll_6} 72 km / h and v _{soll_7} 82 km /H. Thus, in the present example, a sector length is defined by the degree of change within the sector, particularly when the target value deviates up or down by 10 km / h from the previous target value.

6 shows a plan view of a further driving situation, in particular a driving through a curve, which is monitored by means of an embodiment of the method according to the invention.

In particular, it can be seen here how the probability distribution changes over the course of the curve and thus defines an ideal line which deviates from a pure minimum distance to a side line, in particular clearly.

7 shows a flowchart of an embodiment of the method according to the invention.

In S100, an actual value of a parameter, in particular a speed and / or a position, of the vehicle is detected.

In S200, the actual value is compared with a desired value of the parameter, wherein the target value of the parameter is determined dynamically taking into account actual values of other vehicles from the past.

In S300, a warning signal is output to the driver when the actual value exceeds or falls below the target value depending on the type of the parameter.

In an optional step S400, the actual value of the parameter of the, in particular own, vehicle is transmitted to a server and / or another vehicle.

Although exemplary embodiments have been explained in the foregoing description, it should be understood that a variety of modifications are possible. It should also be noted that the exemplary embodiments are merely examples that are not intended to limit the scope, applications and construction in any way. Rather, the skilled person is given by the preceding description, a guide for the implementation of at least one exemplary embodiment, with various changes, in particular with regard to the function and arrangement of the components described, can be made without departing from the scope, as it turns out according to the claims and these equivalent combinations of features.
