Description

  • Field of the invention:
  • The present invention relates to a driver assistance system for assisting a vehicle driver in the transverse guidance of the vehicle.
  • Modern vehicles are increasingly equipped, as standard, with environment-aware driver assistance systems. For example, camera-based systems, such as optical parking aids, 360-degree all-round visibility applications, lane departure warning (LDW) and the like are now state of the art.
  • As the development trend further shows, the number of driver assistance systems will continue to increase in order to provide the driver with the best possible support or to improve driving comfort.
  • However, with constantly new driver assistance systems, which are "very interesting" for the vehicle user in the phase of market introduction, there is also the great danger that the driver feels increasingly patronized in the long run if this assistance system "constantly better knowledge", or Issue warning messages.
  • In particular, if the assistance system issues a warning message if it is not appropriate at all.
  • The sensitivities of the drivers should be considered very carefully.
  • In the realization of such systems, therefore, in order to obtain the customer acceptance special attention must be paid to the fact that
    • a) a warning is not issued too early / is generated, but
    • b) a warning is also not too late / generated, wherein
    • c) the transition area / gray area is often very narrow.
  • If the warning message is too early, the driver feels very easily patronized or harassed by the assistance system (system is rejected because of "malfunction"). In the case of too late a warning, the function of the assistance system can be very easily questioned, even to recourse claims, if an accident has occurred and the assistance system has not warned correctly.
  • From the Scriptures WO 2007/145566 A1 is a generic assistance system, or method for an assistance system known in this by means of eye-tracking (observation of the driver's eyes by means of an interior camera) and consideration of other criteria, a supportive driver assistance system is disclosed.
  • A disadvantage of this solution can be considered that this assistance system, or method for an assistance system according to the Scriptures WO 2007/145566 A1 is susceptible to failure or the results are subject to a certain degree of uncertainty, so that it can easily lead to (as described above) that the assistance system issues a warning message or suppresses if this / this is not appropriate.
  • The object of the invention is therefore to present a solution which is robust against an issuing of erroneous warning messages, or a suppression of required warning messages, and thus prevents drivers from becoming permanently tired of such systems.
  • Solution of the task:
  • This problem is solved by means of a method according to claim 1 or a tracking assistance device according to claim 8. This solution is perceived by drivers as a useful assistance system / lane assist function and should thus obtain a corresponding customer acceptance.
  • In order to be able to better classify this narrow transition area / gray area systemically, or to be able to make the correct decision on the system side as to whether a warning is required or not, the following considerations are taken as a starting point, namely
    • a) in addition to the classical parameters (will be discussed later) 1 explained in more detail) according to the prior art,
    • b) additionally the result of an "eye tracking" in the in 2 described / illustrated manner (modified logic) is taken into account.
  • A method according to the invention for a lane assistance function for situation-specific warning of a vehicle driver when the vehicle leaves the traffic lane and / or drifting off the lane is predicted, comprising at least
    • a) an aimed in the direction of the leading trajectory environment detection system, and
    • b) an optical detection system located in the interior of the vehicle, designed for an eye-tracking function of the vehicle driver, is characterized in that
    • c) whenever the vehicle leaves the lane and / or drifting off the lane is predicted,
    • d) a signal is issued for assistance and / or warning to the driver, wherein
    • e) but deviating from this always no signal for support and / or warning is issued to the driver, if
    • f) the vehicle leaves the lane and / or a drift from the lane is predicted, and
    • g) a possible cause for the agreement and / or predicted lane drift is identified in relation to this event in a timely manner, and
    • h) is detected with the eye-tracking function that the driver has directed his gaze in the direction in which the vehicle comes off the lane and / or a drift from the lane is predicted.
  • The term "eye-tracking" is understood by the experts to mean a method in which it is detected by means of one or more cameras in which direction the driver is looking.
  • One possible reason for the agreement and / or predicted lane drift can be determined according to advantageous embodiments of the invention:
    • From a large speed reduction and / or a steering torque input of the driver;
    • - from the existence of a track-relevant TCM accident report and / or a car-to-X accident report; and or
    • - From the detection of a track-relevant obstacle of the directed in the direction of travel environment detection system or an additional environment detection system for obstacle detection, in particular a radar or Lidarsensorsystem.
  • In an advantageous embodiment of the invention, the method is characterized in that the large speed reduction and / or a steering torque input is only used as a criterion and taken into account when this action / s has been initiated by the driver.
  • In a further advantageous embodiment of the invention, the method is characterized in that a present track-relevant TCM accident message and / or c2x accident message is only used as a criterion and taken into account if it coincides with the current section traveled by the vehicle ,
  • In a further advantageous embodiment of the invention, the method is characterized in that a track-relevant obstacle recognized by the directional detection system in the direction of travel is only used as a criterion and taken into account if the original driving trajectory would represent a collision course with respect to the obstacle.
  • Another object of the invention is a lane assist device for situation-appropriate warning of a driver before an agreement and / or predicted drifting of the vehicle from the lane.
  • The lane assistance device for situation-appropriate warning of a driver before an agreement and / or predicted drifting of the vehicle from the lane comprising at least
    • a) an aimed in the direction of the leading trajectory environment detection system, and
    • b) a located inside the vehicle optical detection system, designed for an eye-tracking function of the driver, and
    • c) an evaluation device for evaluating data from the environment detection system, the optical detection system located in the interior, vehicle sensor data, TCM data, car-to-X data and / or additional environment detection systems is characterized in that the evaluation device is designed for this purpose is
    • d) whenever the vehicle leaves the lane and / or drifting off the lane is predicted,
    • e) to issue a signal for assistance and / or warning to the driver, wherein
    • f) but deviating from this always no signal to give support and / or warning to the driver, if
    • g) the vehicle departs from the traffic lane and / or a drift from the traffic lane is predicted, and
    • h) a possible cause for the agreement and / or predicted drift from the lane is determined in relation to this event in a temporal context, and it is detected with the eye-tracking function that the driver has directed his gaze in the direction in that the vehicle departs from the lane and / or a drift from the lane is predicted.
  • As vehicle sensor data in particular brake pedal positions from which a large speed reduction and / or steering wheel movements of which a Detected steering torque input of the driver and evaluated by the evaluation.
  • Furthermore, the invention comprises a motor vehicle provided with such a tracking assistance device.
  • Further advantages, features and possible applications of the present invention will become apparent from the following description in conjunction with those in the 1 and 2 illustrated embodiments. All described and / or illustrated features alone or in any combination form the subject matter or the method of the present invention, also independently of their summary in the claims or their back references.
  • Show it:
  • 1 : A schematic representation of a flowchart, a method for a LDW function according to the prior art.
  • 2 : A schematic representation of a flow chart, for the realization of the method according to the invention.
  • In the 1 and 2 Depending on a vehicle with an LDW system is required, which has the required (not shown) various communication interfaces / devices, and with the components mentioned in the description.
  • The 1 shows a schematic representation of a flowchart, a method for a LDW function according to the prior art.
  • Like from the 1 As can be seen, the operation is as follows:
    Detects an LDW system ( 10 ), that the vehicle departs from the roadway (threatens to depart), or passes over a boundary line (timely overrun) in step S1, the decision is made whether a signal is output (step S6) or not (step S7) based on several Parameter, where the parameters are interpreted as an indication that leaving the road (eg right turn to the side to dodge OR left shear, to overtake - each without turn signals) might be intended.
  • If this is detected, or determined as an indication that the agreement of the lane / driving over a boundary line could be intended so no warning signal is issued because the driver obviously wants to drive this trajectory deliberately, and would be only "disturbed" by a warning ,
  • The following parameters can be taken as an indication of an intended lane departure, these being known in the corresponding logical link shown as prior art.
    • a) If a vehicle is slowed down quickly (high speed reduction), this is to be taken as an indication that the driver is already reacting to a detected situation (step S2, 1st alternative).
    • b) The same applies if the driver introduces a steering torque (step S2, 2nd alternative).
    • c) If route-relevant (TCM) accident reports are available for the traveled route (step S3, 1st alternative).
    • d) If there are route-relevant Car-to-X accident reports for the route being traveled (step S3, 2nd alternative).
    • e) If an obstacle has been detected by the roadway monitoring system (ie, the environment detection system that is monitoring tracking of the lane or by an additional environmental detection system, eg radar / lidar) (step S4).
    • f) When the driver looks in the direction in which the vehicle is leaving the lane, or passes over a boundary line (step S5).
  • Like from the 1 2, the LDW system according to the prior art does not output a signal in step S7 if at least one of the aforementioned indicia is evaluated positively (with Y = YES), whereas an alarm warning is issued if all of the above are present indicative negative (with N = NO).
  • As a disadvantage of this solution can be considered that this assistance system or method for an assistance system according to the prior art is prone to failure, or the results are subject to a degree of uncertainty, so that it can easily lead to (as described above ) that the assistance system issues or suppresses a warning if this is not appropriate at all.
  • The 2 2 shows a schematic representation of a flowchart for implementing a method according to the invention in a vehicle with an improved LDW system (FIG. 20 ).
  • Deviating from 1 , is in the inventive solution according to 2 , modified the logic of the parameters to be considered in such a way that at least two criteria must be met so that the LDW system does not issue a warning message (step S7).
  • Like from the 2 As can be seen, the operation is as follows:
    If the LDW system recognizes that the vehicle is leaving the roadway (threatens to come to a halt) or is passing over a boundary line (driving over in a timely manner) in step S1, the decision is made whether a signal is output (step S6) or not (step S7) based on several parameters, where the parameters are interpreted as an indication that the exit from the road (eg right turn to the side to dodge OR left shear, to overtake - each without turn signals) might be intended.
  • If this is detected, or determined as an indication that the agreement of the lane / driving over a boundary line could be intended, so no signal is issued (step S7), as the driver obviously wants to drive this trajectory deliberately, and by a warning message only " would be disturbed.
  • As already in 1 can be shown according to the inventive method 2 also the following parameters are evaluated as an indication of intentional lane departure (only in combination with each other), these being new and inventive in the corresponding logical link shown.
    • a) If a vehicle is slowed down quickly (high speed reduction), this is to be taken as an indication that the driver is already reacting to a detected situation (step S2, 1st alternative).
    • b) The same applies if the driver introduces a steering torque (step S2, 2nd alternative).
    • c) If route-relevant (TCM) accident reports are available for the traveled route (step S3, 1st alternative).
    • d) If there are route-relevant car-to-x accident reports for the route being traveled (step S3, second alternative).
    • e) If an obstacle has been detected by the roadway monitoring system (step S4).
  • In contrast to the prior art, the following criterion must additionally be met as an additional criterion (AND operation, no OR operation as in the prior art) for one of the preceding / above criteria, so that the LDW system temporarily becomes "inactive" no warning message off).
    • f) If the driver is looking in the direction in which the vehicle is leaving / leaving the lane, or is driving over a boundary line / prognosis (step S50).
  • Like from the 2 In addition, the LDW system will not output a signal (step S7) if at least two of the aforementioned indicia are positively (Y = YES) scored, whereas a hazard alert is always issued if only one of the previously indicative (Y = YES).
  • From this (according to the inventive concept after 2 ) resulting advantage / e:
    • a) An 'AND operation' (combination) of the evaluation criteria as in the attached 2 significantly contributes to increasing robustness in decision security / degree of decision security.
    • b) A suppression of a warning is only given if at least 2 of the above criteria are met.
    • c) The proposed combination can ensure that the suppression of a required warning message can not be accidentally caused by a driver's casual eye-sight of the driver.
    • d) The quality of the decision reliability is significantly increased compared to the prior art.
  • Annotation:
  • The term used in the descriptions or statement "driver looks absentminded (indifferent) on the road" is an ambiguous indication.
  • The following is a comparison of the present invention over the prior art. An improvement over the prior art achieved by the inventive method / solution concept, since a faulty function is prevented, or the degree of decision reliability of an LDW system is significantly increased.
  • First, a situation is assumed in which the vehicle is drifting or deviating from the lane, and that the driver absentmindedly (indifferently / randomly) looks at the road / current driving trajectory ahead.
  • Then two cases are distinguished:
    • a) It is assumed that there is an obstacle or a warning regarding an obstacle for the section of road currently being traveled, or
    • b) It is assumed that there is NO obstacle or NO warning concerning an obstacle for the currently traveled section of the route.
  • In systems according to the prior art, in case b), a faulty function easily occurs, since a warning message is suppressed whenever the driver accidentally / absent-mindedly directed his gaze to the current Fahrbahntrajektorie and drifts from the road, even if there is NO obstacle or NO warning regarding an obstacle for the currently traveled section of road exists. In this case, a warning message should not be suppressed because it is a real danger case.
  • A suppression of a warning message is only permissible if the driver has accidentally / distractedly directed his view of the current road trajectory and drifts off the road, and there is an obstacle or a warning regarding an obstacle for the currently traveled section, since in this Case, it can be assumed that despite the absent-minded look, the driver nevertheless leads the vehicle safely, since the driving behavior corresponds exactly to what is expected as a result of the detected / present obstacle.
  • In contrast, in the case of the proposed solution according to the invention, in contrast to which a faulty function is counteracted or is reliably prevented with a modified logic.
  • In a proposed method according to the invention with a modified logic erroneous function is prevented because only then a warning message is suppressed if in addition to the "feature", "that the driver accidentally / absentmindedly directed his attention to the current Fahrbahntrajektorie and drifts from the road ", Another criterion must be met.
  • Consequently, in the method according to the invention, a warning message is NOT suppressed if there is no obstacle or NO warning regarding an obstacle for the route section currently being traveled. In this case, a warning message should not be suppressed because there is no reason for drifting off (a warning is appropriate / required), and thus it is a real hazard.
  • A suppression of a warning message is only permissible if the driver has accidentally / distractedly directed his view of the current road trajectory and drifts off the road, and there is an obstacle or a warning regarding an obstacle for the currently traveled section, since in this Case, it can be assumed that despite the absent-minded look, the driver nevertheless leads the vehicle safely, since the driving behavior corresponds exactly to what is expected as a result of the detected / present obstacle.
