Description

Method and evaluation device for evaluating the intervention of at least one driver assistance system of a vehicle

technical field

The invention relates to a method and an evaluation device for evaluating the intervention of at least one driver assistance system of a vehicle in the driving operation of the vehicle.

Background technique

Driver assistance systems are known from the prior art for supporting the user of the vehicle while the vehicle is in motion, eg for improving driving safety and/or for avoiding and/or mitigating accidents.

There are many accident avoidance systems installed in modern vehicles. Many of these systems have evolved quietly—that is, while drivers pay for these systems, drivers are not always aware that these systems support the vehicle while it is in motion or even avoid accidents. An example of this is ESC (abbreviation for "Electronic Stability Control", in German Elektronische Stabilitätskontrolle, often also called Electronic Stability Program ("ESP")), a driver assistance system for the regulation of driving dynamics, which in particular The deflection of the vehicle can be counteracted by the targeted braking of the individual wheels of the motor vehicle.

ESC intervention avoids a side-slip accident (Schleuderunfall) when the vehicle is oversteering or understeering. During the ESC intervention, the driver only perceives a brief "jitter" at the wheel and usually cannot relate this at all - he may think that he is driving over a stone or a ground sill. Here, ESC just might have saved his life.

A similar situation exists in virus scanners on computers in different technical fields. These virus scanners are thus made visible to the user/customer, ie the virus scanner reports after each virus attack with a "virus attack blocked" and generates eg monthly statistics of how frequently scanned and how frequently viruses are blocked . In the automotive field, this or similar solutions are not known or used.

US 9 773 281 B1 describes an accident recognition device for a vehicle, which is configured to determine that an accident in which the vehicle is involved has occurred. After the occurrence of the accident is determined, the characteristics of the accident can be determined, and vehicle data and data about the vehicle occupants can be obtained.

A method for outputting a warning of a driver assistance system in a vehicle is known from US Pat. No. 9,487,138 B2, in which data on the movement of the vehicle and data on the risk of an accident in the surroundings of the vehicle are detected. The detected data are evaluated and associated with specific accident risk levels. Alarms are output based on the associated accident risk level. For example, when a critical collision situation is reached, the driver is notified of the start of an automatic vehicle adjustment, so that he understands the cancellation of the corresponding driving task.

A vehicle system for accident prevention is described in US 8 766 846 B2, which has an object recognition device. When an object is detected, an accident prevention response signal may be transmitted to the vehicle's braking device, which then brakes the vehicle independently of the vehicle's driver.

SUMMARY OF THE INVENTION

The object of the present invention is to overcome the disadvantages known from the prior art and to provide a method and an evaluation device for evaluating the intervention of at least one driver assistance system of a vehicle in the vehicle operation of the vehicle, by means of which the user is The intervention of the occupant assistance system is likewise informed when it ensures higher driving safety.

According to the invention, this object is achieved by a method for evaluating the intervention of at least one driver assistance system of a vehicle in the driving operation of the vehicle.

In the method according to the invention for evaluating the intervention of at least one driver assistance system of a vehicle in the driving operation of the vehicle, a driver assistance system for supporting a user of the vehicle, in particular with regard to driving safety, is suitable for driving the vehicle. And provision is made to intervene in the driving behavior (of the vehicle). The user may be the driver and/or another passenger of the vehicle.

According to the invention, the evaluation device determines, in at least one intervention of the driver assistance system, whether this intervention is (and/or was) an intervention per se perceptible to the user.

Interventions that are perceptible (or should be perceived) by the user are understood in particular to mean that the user can in principle (independently, only through his own sensory impressions) perceive the interventions themselves in the driving operation (for example, through irregularities occurring in the driving operation) (e.g. bumps) and this perception can be regarded and/or linked, in particular substantially unambiguously and/or with a predetermined probability, as an effect of an intervention of the driver assistance system in the driving operation. Preferably, the user can distinguish per se perceptible interventions from other irregularities occurring in the driving operation for other reasons (eg ground sills).

The driver assistance system is preferably a driver assistance system for increasing driving safety and particularly preferably a driver assistance system for avoiding and/or mitigating accidents. Preferably, the driver assistance system is an electronically controlled driver assistance system.

Preferably, at least one driver assistance system of the vehicle and in particular a plurality of driver assistance systems of the vehicle (respectively) are accident avoidance systems.

Several driver assistance systems, in particular several accident avoidance systems, are preferably installed in the vehicle. Preferably, these driver assistance systems report their interventions to the evaluation device and preferably to the evaluation algorithm (of the evaluation device), in particular via the data bus.

In particular, the evaluation device is suitable and intended for determining whether an intervention carried out and/or carried out and/or triggered by a driver assistance system (or driver assistance systems) of the vehicle is to be perceived by the user of the vehicle And preferably an intervention perceived by the user of the vehicle.

Preferably, the evaluation device determines whether the intervention is imperceptible to the user (especially per se).

In other words, the evaluation device or the evaluation algorithm determines, for example, via the evaluation of system data (for example data of at least one or more driver assistance systems) whether the intervention of the driver assistance system (in particular the accident avoidance system) is appropriate for the user (for example the driver) It is not immediately recognizable or can itself be associated with a user (eg a driver).

This provides the advantage that the user may be informed of unaware and/or imperceptible interventions. Advantageously, the user can be made sensitive to the activities performed by the driver assistance system. The user advantageously thus obtains the possibility to analyze the driving situation and/or (their) driving behavior and/or environmental conditions (eg climatic conditions) in view of their potential danger and to adapt or change the future driving behavior.

By reporting interventions that are imperceptible per se, eg to the user, the importance of driver assistance systems can be shown to the user on the one hand, and similar dangerous situations can be prevented or mitigated in the future by adapting the user's driving behavior on the other hand.

Preferably, (in particular each) driver assistance system that carries out and/or triggers the intervention (simultaneously or staggered in time) triggers the activation of the evaluation device for determining the perceptibility of the intervention to the user.

Preferably, the evaluation device determines the perceptibility of the respective intervention for a plurality of interventions and in particular for each intervention (eg of a trip).

In a preferred method, the perceptibility of the intervention is determined based on an evaluation of data from a driver assistance system or driver assistance systems. This provides the advantage that the perceptibility of the intervention, in particular itself, to the user can be deduced from the data of the driver assistance system or driver assistance systems.

Preferably, the data of the driver assistance system or of the driver assistance systems comprise the type and/or duration of intervention of the (respective) driver assistance system, the action performed, the intensity of the intervention required, at least one state Information.

In a further preferred method, the determination of the perceptibility of an intervention is carried out on the basis of previously known and/or past similar interventions of the driver assistance system. Preferably, the evaluation device or the evaluation algorithm utilizes a priori knowledge (Vorwissen). For example, intervention by an ESC system may be more difficult to associate as accident avoidance by a user or by a driver than intervention by an emergency braking system for collision avoidance.

Preferably, the link between the intervention and its perceptibility, known and/or determined from a priori knowledge, is stored in a memory device which is accessible to the evaluation device and/or which is a vehicle and in particular an evaluation device. components of the device.

In a further (alternatively or additionally) preferred method, the perceptibility of the intervention (as such) is determined based on the intensity and/or type of intervention of the driver assistance system. This provides the advantage that several of the interventions can be graded as perceptible or non-perceptible, eg without high evaluation or computational effort. Thus, for example, the execution of emergency braking by the emergency braking system can (usually) be classified as a (per se) perceptible intervention without further evaluation.

Preferably, in determining the perceptibility of an intervention, it is taken into account which driver assistance system the intervention is or has been implemented. For example, which intervention intensity and which intervention setting is to be carried out and/or (has been) carried out can be reported to the evaluation device by the central computer of the vehicle and/or by the corresponding driver assistance system.

In a further preferred method, the perceptibility of the intervention (in itself) is determined on the basis of at least one (measured) value detected and/or determined by at least one chassis sensor device and/or ambient sensor device.

Preferably, the evaluation device and/or the evaluation algorithm use information from chassis sensors (or chassis sensor devices), such as inertial, altitude, and wheel speed sensors, as well as ambient sensors, such as cameras, radar, lasers, or Information from the ultrasonic sensor system: Preferably, the algorithm compares the behavior of the vehicle before the intervention and during the intervention in order to assess how strongly the intervention can be felt by the driver compared to normal driving.

Preferably, the chassis sensor device is selected from the group of sensor devices comprising at least one inertial sensor device, at least one height sensor device, at least one wheel speed sensor device, etc., and combinations thereof.

The advantage is provided by the consideration of the value(s) detected and/or determined by the chassis sensor device, ie the movement and/or sway of the chassis and/or the vehicle can thus be determined very precisely. Thus, in particular, the evaluation device can advantageously determine very precise movements and/or swayings that are caused or have been caused by the intervention of the driver assistance system and which can be felt and/or (physically) perceptible by the driver.

Preferably, the perceptibility of the intervention (as such) is determined based on (measured) values of at least one vehicle sensor device and/or at least one ambient sensor device, of which at least one (measured) value is before the intervention and in which At least one additional (measured) value of is detected (or recorded) and/or determined during the intervention.

Preferably, the comparison of the behavior of the vehicle before the intervention and during the intervention is carried out, in particular, by means of an evaluation device. In this way, it can be advantageously evaluated how strongly the intervention can be felt by the user compared to normal driving or previous driving.

In a further preferred method, the user's reaction to the intervention is detected by means of a passenger monitoring device, and the perceptibility of the intervention is determined based on the user's detected reaction. This provides the advantage that the user's perceptibility is not deduced indirectly, eg from (measured) values of the chassis sensor device, but can be observed directly at the user himself whether he perceives and/or perceives an intervention. This provides the advantage that perception thresholds associated with individuals can be taken into account.

Preferably, the passenger monitoring device optically observes the user and/or the user's behavior (at least temporarily and in particular before and/or during the intervention). Preferably, the passenger monitoring device thereby determines the perception of the intervention by the user. Preferably, the passenger monitoring device has an image detection device, such as a camera and in particular an interior camera. Preferably, the passenger monitoring device is a (in-vehicle) camera.

It is also conceivable that the passenger monitoring device monitors the user via tracking the gaze path (at least temporarily and in particular before and/or during the intervention).

Preferably, the occupant monitoring device and/or the evaluation device are adapted and intended to be determined from an optical image comprising at least partially the user, eg by withdrawal and/or change of body posture and/or change of gaze path and/or pupil dilation The passenger's state of panic and/or heightened attention.

Preferably, the passenger monitoring device determines the perception of the intervention (and thus the perceptibility of the intervention) by means of haptic and/or tactile elements of the passenger monitoring device and/or the vehicle. The haptic and/or tactile elements can be, for example, operating elements of the vehicle, such as a steering wheel and/or a gas pedal and/or a brake pedal. Preferably, the passenger monitoring device determines the user's reaction to the intervention from the actuation of the operating element and/or changes in the intensity and/or movement dynamics of the user at the tactile and/or tactile element, in particular at the operating element.

Preferably, the occupant monitoring device and/or the evaluation device determines whether the user is in a state of panic and/or a state of increased concentration in relation to the intervention in time. The connection in time is understood in particular as the reaction time of the user. Typical reaction times can be stored, for example, on a memory device, in particular the evaluation device and/or the vehicle. It is also conceivable to store a user-specific reaction time on the storage device, which is used to evaluate the perceptibility and/or perception of the intervention by the user, taking into account the driver's reaction to the intervention.

Furthermore, the (evaluation) algorithm and/or the evaluation device preferably uses information from an interior camera and/or operating elements (eg steering wheel, gas pedal and brake pedal). The (assessment) algorithm observes the driver's response to the intervention and evaluates the response based on this information. For this, the driver response is preferably graded as weak, medium and strong, for example.

Preferably, the user's reaction detected by the passenger monitoring device is graded into one of a plurality of preset categories of different reaction intensities, in particular by the evaluation device (for example: graded into (four) categories, no reaction|weak reaction|medium Reaction | Strong Reaction).

Preferably, whether the user has consciously and/or unconsciously perceived the intervention and/or whether the user is able to (have) perceived the intervention can be determined from the category to which the response belongs and/or the intensity of the intervention and/or the parameter representative of the intervention to the intervention itself.

Preferably, data from different sources (prior knowledge, running gear sensors and/or ambient sensors and/or interior cameras and/or operating elements) are fused with each other, particularly preferably the field of prior knowledge, running gear sensors and/or Data from the field of ambient sensors and the field of interior cameras and/or operating elements are fused with each other. For this, machine learning methods such as neural networks, deep learning or also Bayesian networks can be used.

Preferably, the evaluation device is capable of evaluating a plurality of data, in particular data of a plurality of past interventions and the The perceptibility of the intervention and/or the perception of the intervention by the user is determined on the basis of the detected ambient data and/or vehicle data and/or user response data associated therewith.

In a further preferred method, the evaluation device provides an output signal for output to the user as a function of the result of the determination of the perceptibility of the intervention. This provides the advantage of increasing the user's awareness of how the driver assistance system works and/or the frequency and/or importance and/or intensity of interventions. For example, it can thus be shown to the user that an accident can eg be prevented or (significantly) mitigated by intervention.

For this purpose, existing displays, such as vehicle speed displays or navigation displays, can be used. Whether this display should take place can be done by the driver in a suitable menu, eg by clicking on "Show intervention statistics"

The user obtains direct feedback on the intervention event through a temporal reference.

Preferably, the output signal is output by the output device automatically and/or without an indication of the output by the user.

However, it is also possible that the user may input (eg via a human-machine interface) instructions for outputting all and/or some of the above-mentioned information related to one or more interventions and/or intervention statistics. This can be supported, for example, via menu guidance of the human-machine interface.

Preferably, statistics of the intervention of one or more accident avoidance systems in the vehicle are displayed by an output device.
