Definitions
- the invention relates to a method for assessing the driving safety of a driver of a vehicle, wherein the driver of the vehicle is identified as a person in the vehicle.
- a method for determining the usage behavior of a motor vehicle system is known from DE 102012 014 191 A1.
- the motor vehicle system offers a function that can be used by the driver.
- the method provides that corresponding data about the use of the function is sent to a central computer via a communication device arranged in the motor vehicle.
- DE 102021 003489 A1 discloses a method for detecting a gradually decreasing driving performance of a vehicle driver, in which an individual driving-specific behavior as well as physiological and emotional characteristics of a driver as well as his health data are recorded, which are combined and evaluated to determine the driving performance.
- US 2016 0 046298 A1 discloses a system that includes a motion sensor that can essentially create a real-time image of the driver's movement while driving. This data can be used to detect an event that leads to a driver's distraction.
- US 2021 0 398 562 A1 deals with a computer-implemented method for replaying media content, using sensor data to detect the user's mental state.
- US 2007 0275 770 A1 deals with a hands-free device that is attached to the sun visor of a vehicle and communicates with a remote hands-free device.
- the invention is based on the object of specifying a method for assessing the driving safety of a driver of a vehicle.
- a method for assessing the driving safety of a driver of a vehicle whereby the driver of the vehicle is identified as a person in the vehicle, provides according to the invention that over a predeterminable period of time during a ferry operation, individual physiological and driving-specific characteristic values of the driver as well as media usage characteristic values of the driver are recorded, processed and stored.
- a driving safety value is determined based on the recorded characteristic values and, depending on the determined driving safety value, a recommendation or warning is issued in the vehicle.
- driving safety is mapped as a function of vehicle and media usage characteristic values. In particular, an individual driving safety of the driver can be mapped based on the vehicle and media usage characteristic values.
- the vehicle and media usage characteristic values are identified which influence the driving safety value, in particular negatively. For example, methods can be used for this which can identify those characteristics which influence function values, in particular for driving safety assessment, the most and are applied to an individual function approximation.
- the risk of driver distraction particularly with regard to media use
- the risk of an accident can be significantly reduced by recognizing individual vehicle and media usage, which increases a personal risk of being involved in and/or causing a traffic accident, since the use of media in the vehicle is a potential source of distraction.
- the driver is given the opportunity to adapt his behavior and thus reduce the risk of an accident.
- the method in one embodiment provides that the driver's physiological characteristic values are determined based on a heart rate, a breathing rate and a skin conductance value of the driver.
- the physiological characteristic values can be used to determine in particular whether the driver is relatively relaxed or is in a stressful situation. In stressful situations in particular, the risk of accidents can increase because the driver reacts strictlyally and/or tends to overlook other road users.
- the driver's driving-specific characteristic values are determined based on the acceleration of the vehicle, wheel speeds, engine speeds, driver assistance interventions, lateral positions of the vehicle in its lane and/or distances to vehicles driving ahead. Using these driving-specific characteristic values, a connection can be established between a driver's distraction and the driver's driving style caused by the distraction. If the distance to a vehicle driving ahead decreases and/or the vehicle drives over a lane marking, it can be assumed that the driver of the vehicle is distracted, in particular by certain media usage, for example by operating a mobile device.
- media usage characteristic values are determined based on operations of a mobile device, operations of an infotainment system of the vehicle and/or set volumes of media playback in the vehicle. For example, a driver of the vehicle is more distracted from driving than another driver when the media playback volume is comparatively high, so that the driving safety assessments of the two drivers differ despite the same conditions.
- the driver's media usage is analyzed in training using computer-aided speech analysis methods.
- media usage can be analyzed using computer-aided speech analysis in relation to content and the moods that are then generated in a driver in order to assess the driver's driving safety when driving the vehicle and, under certain circumstances, to alert the driver to his or her distraction due to this media usage.
- an embodiment of the method can provide for the driver's emotions to be determined based on recorded facial, speech and/or physical signals. Based on the driver's emotions determined, a relatively reliable determination is possible as to whether the driver is distracted by media use.
- one embodiment of the method provides that the driver is recommended an alternative media usage in the vehicle based on a driving safety value predicted at least based on the media usage signals.
- the driver's media usage is analyzed in real time, whereby the value for the driving safety assessment is determined and, for example, depending on the driver's determined physiological values, the driver is recommended to consume, i.e. listen to, relaxing media, for example in the form of music.
- the method provides that the individual physiological and driving-specific characteristic values of the driver as well as the media usage characteristic values of the driver recorded over the predeterminable period of time during ferry operation are transmitted to a central computer unit that is data-technically linked to the vehicle.
- these can be transmitted to the central computer unit for aggregation, processing and storage.
- Vehicles in a vehicle fleet transmit the recorded feature values to the central computer unit in order to identify the feature values, in particular to determine factors relevant to the vehicle fleet, for example media usage and its respective distraction.
- Fig. 1 shows schematically a device for carrying out a method for assessing the driving safety of a driver of a vehicle
- Fig. 2 shows a schematic one-dimensional diagram of driving safety dependent on media usage.
- Figure 1 shows a vehicle 1 and a device for carrying out a method for driving safety assessment FB of a driver of the vehicle 1 (not shown in detail), whereas Figure 2 shows a diagram D of a driving safety FS dependent on a media usage MN.
- driver distraction during operation of the vehicle 1 is the cause of a comparatively large proportion of traffic accidents.
- media use MN i.e. use of a mobile device, in particular operation of a smartphone, setting up podcasts, music and/or operation of an infotainment system of the vehicle 1, is a possible source of driver distraction.
- the method described below helps the driver of the vehicle 1 to identify which individual media usage MN increases his personal risk of being involved in and/or causing a traffic accident. In addition, the method gives the driver an opportunity to adapt his behavior and thus reduce the risk of an accident.
- the device has a control unit 2, a further control unit 3, for example of an assistance system, at least one interior microphone 4, at least one vital sensor 5, at least one interior camera 6, at least one exterior camera 7 and a central computer unit 8, to which the vehicle 1, in particular the control unit 2, is coupled in terms of data technology.
- the vehicle 1 belongs to a vehicle fleet to which other vehicles (not shown) belong, which are also coupled in terms of data technology to the central computer unit 8.
- signals detected by means of the interior microphone 4, the vital sensor 5, the interior camera 6, the exterior camera 7 and the further control unit 3 are aggregated and recorded in the control unit 2.
- interactions between the driver and the vehicle 1 are recorded, i.e. stored, in the control unit 2.
- the driver of the vehicle 1 can be identified using a variety of methods, for example by captured image signals from the interior camera 6 and/or the exterior camera 7, and known methods, for example by means of computer-aided vision, for example in relation to facial recognition, using a personalized vehicle key and/or by entering a personal identification number on the vehicle side.
- the driver is identified as a person so that captured signals and values and data captured on the basis of these can be clearly assigned to this person.
- personal information and characteristics of the driver such as age and/or whether the driver is a smoker, can be or will be stored in a personal driver profile.
- physiological characteristic valuesAdata such as a heart rate, a breathing rate, a skin conductance value, etc. can be determined based on recorded signals from at least one vital sensor 5.
- these characteristic valuesAdata can be determined based on recorded signals from optical and/or electronic sensors in the vehicle 1 or in the vehicle seat.
- Driving-specific, particularly driving dynamics characteristic valuesAdata relating to the driver can be determined using signals recorded by acceleration sensors of the vehicle 1 and other sensors, using signals recorded for example wheel speeds and/or engine speeds. Based on the recorded and processed signals, for example, a lateral acceleration, a longitudinal acceleration, a speed distribution, a maximum engine speed and a distribution of the engine speeds can also be determined.
- Driver-specific feature values A data can also be extracted based on information available from the additional control unit 3. For example, a number of driver assistance interventions, such as initiated emergency braking, steering wheel interventions to keep in a lane, as well as information about a lateral positioning of the vehicle 1 in its lane and/or information about distances to vehicles ahead selected by the driver of the vehicle 1 can be used.
- driver assistance interventions such as initiated emergency braking, steering wheel interventions to keep in a lane, as well as information about a lateral positioning of the vehicle 1 in its lane and/or information about distances to vehicles ahead selected by the driver of the vehicle 1 can be used.
- Feature valuesAdata relating to an individual driver-specific driving style or an individual driver-specific driving behavior can be determined using a variety of methods. For example, a classification of the driving behavior can be carried out on the basis of recorded sensor signals.
- the method for assessing the driving safety of the driver of the vehicle 1 provides that in the vehicle 1, feature valuesAdata on individual physiological, emotional, driver-specific driving dynamics and driving behavior-specific information of the driver are recorded and aggregated in the control unit 2 of the vehicle over a predeterminable, comparatively long period of time.
- a driving value for the driving safety assessment FB i.e. a driving performance parameter, is determined from a driver-specific feature space.
- This value for the driving safety assessment FB simultaneously forms a characterization of a driving style of the driver and characterizes or evaluates the safety of the driver's driving style.
- individual vehicle and in particular media usage MN is determined based on signals recorded by the vehicle's sensors. Vehicle usage is recorded as switching on an air conditioning system, opening a sunroof, etc. In particular, media usage characteristic values are determined.
- Media usage includes the operation of a driver's mobile device, i.e. a smartphone, setting podcasts, music and/or operating an infotainment system of vehicle 1, a selected volume of media playback, etc., also recorded on the basis of signals from the sensors installed in vehicle 1.
- a driver's mobile device i.e. a smartphone, setting podcasts, music and/or operating an infotainment system of vehicle 1, a selected volume of media playback, etc., also recorded on the basis of signals from the sensors installed in vehicle 1.
- media usage MN it can be analyzed using methods of computer-assisted language analysis, for example with regard to content, sentiment or similar.
- additional personal physiological and driver-specific feature valuesAdata can be used to expand the above-mentioned feature space.
- an individual map of the driver's driving safety assessment FB can be created as a function of the vehicle usage characteristic values and the media usage characteristic values.
- a heuristic function approximation can be used, for example a linear mapping of the media usage feature values with a target value of the driving safety assessment FB.
- function approximations can be trained using machine learning methods in the vehicle 1. or trained.
- the vehicle and media usage characteristics are used as input variables and the driving safety assessment FB as the target value.
- Machine learning algorithms then determine the function approximation that can best map the characteristic values to the corresponding target values.
- an acoustic, optical and/or haptic warning can be issued to the driver in the vehicle 1.
- a current individual vehicle and media usage MN is analyzed in real time and mapped as a driving safety value FS using the function approximation. If it is determined that the driving safety value FS falls below a predetermined threshold, the optical, acoustic and/or haptic warning is issued in the vehicle 1.
- options for action can be suggested to the driver which essentially do not have a negative impact on driving safety FS, but may even increase it positively.
- the method provides that individual images and/or the underlying feature values are transmitted by means of wireless communication K from the vehicle 1 to the central computer unit 8, which can be a so-called cloud or a data center of a vehicle manufacturer.
- the feature values are aggregated and processed in order to identify the feature values that are relevant for the vehicle 1 and the other vehicles in the vehicle fleet, in particular for driving safety FS when using media MN.
- a driver drives a comparatively high-value luxury vehicle as vehicle 1 and switches on the infotainment system of vehicle 1.
- the driver selects a podcast to play in vehicle 1. Based on the speech analysis performed in relation to the podcast, it is recognized that it is a current stock market report of a certain company.
- a diagram D is shown with a driving safety rating FB assigned to each driver when using media MN.
- a maximum driving safety value FS is achieved with a media usage MN with a value of zero, i.e. no media usage MN in the ferry operation of vehicle 1. This maximum value is represented by a star S1.
- driving safety FS For another driver, whose driving safety rating FB is shown by a dashed line, the value of driving safety FS increases with increasing value of media usage MN.
- the media usage MN in particular its characteristic value, can be, for example, the set volume of a media playback in vehicle 1.
