Description

[0001] The invention relates to a method for evaluating the driving behavior of a vehicle during a journey.

[0002] Furthermore, the invention relates to an electronic evaluation system with an evaluation device. The invention also relates to a vehicle with an electronic evaluation system.

[0003] The driving behavior of manually or autonomously driven vehicles is a decisive factor in whether the vehicle can be operated efficiently, especially with regard to energy consumption and CO2 emissions. High energy consumption, i.e., high fuel consumption or high electricity consumption, is a particular problem for future and current vehicles.

[0004] For example, DE 10 2014 226 886 A1 discloses a method for controlling traffic flow in which the information about the time until a traffic light switches to another traffic light phase is used to give the driver of a vehicle a speed recommendation for approaching the traffic light.

[0005] Furthermore, DE 10 2015 204 122 A1 discloses a traffic light assistance system for a vehicle with a display device for the driver of the vehicle and a control device configured to generate at least one display element depending on traffic light phase information and vehicle information. The control device can be configured to display the display element relative to a vehicle symbol on the display device.

[0006] An object of the present invention is to evaluate a driving style of a vehicle, in particular of a driver of the vehicle, in such a way that the vehicle can be operated more efficiently, in particular in a more energy-saving manner.

[0007] This problem is solved by a method, an electronic evaluation system, and a vehicle according to the independent patent claims. Useful further developments arise from the dependent patent claims.

[0008] One aspect of the invention relates to a method for evaluating a driving behavior of a vehicle during a travel journey, comprising: - In particular, recording an acceleration process describing the driving behaviour or a braking process of the vehicle describing the driving behaviour in a respective driving situation during the journey by means of a recording device; - In particular, transmitting the recorded acceleration process or the recorded braking process of a respective driving situation to an evaluation device; - In particular, providing reference acceleration and braking processes relating to a wide range of driving situations to the evaluation device; - In particular, determining an evaluation result relating to the driving behaviour by the evaluation device by comparing the recorded acceleration process of a respective driving situation with the reference acceleration processes or the recorded braking process of a respective driving situation with the reference braking processes.

[0009] The proposed method can be used to improve, or in particular correct, the driving behavior of the vehicle by taking the evaluation result into account, so that the vehicle can be made more efficient, particularly with regard to energy consumption and / or CO2 emissions. This can be achieved primarily through the evaluation result determined, calculated, or determined by the system. The evaluation result can, for example, be determined continuously during the journey for a respective or each driving situation, so that the driving behavior can be continuously improved. It is also conceivable that, after the journey has ended, an evaluation, analysis, or evaluation of the driving behavior relating to the journey, in particular the entire journey, can be generated. This, in turn, can be advantageously used for subsequent journeys or for other vehicles.

[0010] For a particular driving situation of the vehicle during travel or driving, a system-based, particularly automatic, detection of an acceleration or braking process in the respective driving situation can be recorded. A detection device, particularly an electronic one, can be used for this purpose.

[0011] For example, a driving situation could be negotiating a curve or a section of highway, a traffic jam, a traffic light situation, a traffic situation in or outside of a city, or any other traffic situation. Using the recording device, the acceleration and / or braking process performed for a particular traffic or driving situation can be detected or recorded. If, for example, the acceleration process is unnecessarily excessive, this could lead to unnecessary energy consumption and thus unnecessarily high CO2 emissions.

[0012] Furthermore, if a red traffic light or another impending stop is detected early, rapid braking can occur, which can effectively influence the driving style or behavior. In this case, predictive braking would be desirable. This can be used for a specific driving situation using the system's recorded situations. Further information can also be recorded for a specific driving situation.

[0013] The recorded acceleration process or the recorded braking process for a respective driving situation can be transmitted or made available on the system side to the evaluation device, which can be an electronic computing unit.

[0014] The assessment device can, for example, be integrated into the vehicle or external to the vehicle. Thus, the collected information or data can be provided to the assessment device via either a wireless or wired communication connection.

[0015] Furthermore, the evaluation device can, for example, have a database or be connected to a database via communication technology. This allows reference data, such as historical data, to be provided for a wide variety of driving situations. In particular, reference acceleration processes and reference braking processes can be provided. These reference braking processes and reference braking processes can be referred to as target braking processes and target acceleration processes. Accordingly, a system-side comparison can be performed between the detected acceleration process as the actual acceleration process or the detected braking process as the actual braking process with the reference values ​​or comparison values. In other words, a system-side target-actual comparison can be performed.This allows the system to perform an evaluation or assessment, i.e., the evaluation result, to evaluate driving behavior in terms of energy consumption and CO2 emissions, and especially wear-reducing performance. This evaluation result can then be made available for corresponding evaluations, analyses, or control systems.

[0016] Optionally, vehicle-specific or internal data can be recorded using a vehicle recording device. For this purpose, the recording device can have multiple sensors. For example, the target acceleration or braking process can be determined based on the current and / or past driving state of the vehicle. Furthermore, data such as object data from objects in the vehicle's surroundings or from information sources external to the vehicle, such as external sensors, can be provided to the evaluation device and taken into account when determining the target acceleration or braking process.

[0017] Based on the historical data from the database and the determined target acceleration or braking process, the reference data can be determined or provided.

[0018] In particular, the proposed method may be a computer-generated method.

[0019] In one embodiment, the evaluation result is output to a user of the vehicle via an electronic output unit. In this case, a change in driving behavior, in particular relating to a respective driving situation, can be output or displayed to the user, in particular to the driver of the vehicle, during the journey or after the journey has ended. This allows the user to adapt their driving style or behavior by making manual corrections or interventions while the journey is in progress, or they can use this information output by the system, i.e. the evaluation result, to adopt an energy-saving and CO2-minimized driving style during future journeys. For this purpose, the electronic output unit can be an infotainment system, head-up display, or another output unit already present in the vehicle.It is also conceivable that the output is provided via the user's mobile device, such as a smartphone. In particular, the evaluation result can be displayed visually, acoustically, or haptically.

[0020] In addition to or instead of this, the evaluation result can be provided to at least one vehicle system of the vehicle. Accordingly, the corresponding machine-determined evaluation result can be provided or transmitted to a vehicle system or vehicle component, such as a driver assistance system. This allows vehicle systems and / or vehicle components of the vehicle to be adapted accordingly and, in particular, configured or preconfigured in order to be able to implement system-based interventions in the driving behavior and thus in the driving style of the vehicle in order to achieve more efficient vehicle travel.

[0021] In one exemplary embodiment, it is further provided that, based on the evaluation result, at least one item of adaptation recommendation information, with which the driving behavior can be adapted by the user, is generated and output to the user by means of the electronic output unit. With the aid of the evaluation device, which can have an electronic evaluation unit, for example, one or more items of adaptation recommendation information can be generated or created. These can be output to the driver as user of the vehicle visually, acoustically, or haptically as information, instructions, recommendations, or warnings during or after travel in the vehicle. This allows the driver to be given instructions, for example via a head-up display in the vehicle, so that the driver can adapt their driving style and thus their driving behavior.For example, this can indicate to the driver that they should brake or accelerate earlier, or later, in a given driving situation. This allows the driver to adjust their driving style accordingly.

[0022] It is also conceivable that multiple adjustment recommendation information items could be issued in a cascaded manner, depending on the current, particularly critical, driving situation. The issued adjustment recommendation information could provide the user with a learning process and thus a learning outcome, allowing the driver to continuously improve their driving behavior, especially their driving style.

[0023] Additionally or instead, based on the evaluation result, at least one adaptation signal, by means of which the driving behavior can be adapted on the system side, can be generated by an electronic evaluation unit and transmitted to the at least one vehicle system. Thus, the system analyzes the acceleration or braking process performed in a driving situation in order to adapt or configure the vehicle system or multiple vehicle systems accordingly in order to adapt the driving behavior. In this case, at least one electronic signal, i.e., the adaptation signal, can be generated or produced using the electronic evaluation unit, which can in particular be a component of the evaluation device.This allows the vehicle system, vehicle functions, and / or vehicle components to be configured to achieve a system-based adaptation of the vehicle's driving behavior. This can involve the vehicle being at least partially autonomous.

[0024] The evaluation result may be electronic information regarding an evaluated acceleration process or an evaluated braking process of the vehicle.

[0025] The acceleration or braking processes are processes carried out during a real journey of the vehicle in real road traffic.

[0026] In one exemplary embodiment, the evaluation result provides a deviation between the detected acceleration process of a respective driving situation and a reference acceleration process corresponding to the respective driving situation, or between the detected braking process of a respective driving situation and a reference braking process corresponding to the respective driving situation. Accordingly, with the aid of the comparison performed, in particular the target-actual comparison, it can be determined or specified to what extent the braking process performed or the acceleration process performed in a respective driving situation deviates from the reference or the target result.Based on the respective deviation, the system can determine whether the braking or acceleration maneuver performed has a positive or negative impact on efficient driving. The greater the respective deviation, the more negative the impact on the vehicle's efficiency. The smaller the deviation, the more efficient the driving style.

[0027] To enable the system to determine whether positive or negative driving behavior is present, predefined thresholds or limits can be specified. For example, a deviation of 5%, especially 10%, and especially greater than 15%, can be considered a detrimental braking or detrimental acceleration process. Depending on the type of deviation, system-based or manual interventions in the driving behavior can be made.

[0028] In addition to or instead of this, a graphical representation and / or statistical representation of the evaluation result can be generated based on the deviation relating to a particular driving situation. In other words, the extent to which the vehicle user's driving style or behavior deviates from the target or from the difference can be visually shown or explained to the user. This can visually show the user which improvements or countermeasures they must or should take to achieve efficient driving. The graphical representation and / or statistical representation can, for example, be output electronically in the vehicle, or these representations can be usefully used as a history for future journeys of the vehicle and / or other road users.

[0029] To determine the deviation, the system can use a recorded acceleration or braking event to determine a reference driving situation that matches, or in particular, essentially matches, the current driving situation. The appropriate reference driving situation can be selected as a historical or stored driving situation to use for comparing the braking or acceleration events.

[0030] In one exemplary embodiment, the detection device detects environmental information relating to the vehicle's surroundings for a respective driving situation, with the detected environmental information being taken into account when determining the evaluation result. Using the detection device, which may, for example, comprise a plurality of individual sensors, environmental information relating to the vehicle's surroundings can be detected for a respective driving situation or situations present in the vehicle. In other words, environmental detection takes place here, so that extensive information is available for the determination and evaluation, enabling the system to evaluate or assess the driving behavior in this driving situation.For example, traffic situations, other road users, conditions in the surrounding area, type of road on which the vehicle is traveling, weather conditions in the surrounding area, road conditions, surrounding road users or other information relating to the vehicle's surroundings can be recorded.

[0031] In one exemplary embodiment, the acquired environmental information of a respective driving situation is used to provide information about a speed limit relating to the respective driving situation and / or information relating to a safe distance maintained by the vehicle from another vehicle in the vicinity during the respective driving situation. The acquisition of the speed limit applicable in the respective situation or the speed limit and / or information relating to a safe distance maintained from a vehicle in front are important influencing factors with regard to the evaluation of the braking process or the acceleration process. In particular, an acceleration process should be carried out in such a way that the existing speed limit is adhered to. If this is not the case, this will have a negative impact on the evaluation result.If the speed limit is observed during acceleration, this indicates positive driving behavior. When braking, a specified safety distance should always be maintained from the vehicle in front to prevent rear-end collisions. This is also taken into account when evaluating the braking maneuver.

[0032] Further information, which can be taken into account in determining the evaluation result, can be provided, for example, to the vehicle-external information source.

[0033] For example, the detection device can detect and evaluate traffic signs in the vehicle's vicinity, allowing the speed limit to be determined. This information can also be made available to the evaluation device via communication technology. Sensors, particularly those located in the front of the vehicle, can be used to determine the safety distance.

[0034] In one exemplary embodiment, it is provided that, for a detected acceleration process or a detected braking process in a respective driving situation, information about the current route on which the vehicle is moving and / or a current position of the vehicle is determined. Based on the information about the current route and / or the current position of the vehicle, a corresponding reference acceleration process or reference braking process is determined from the provided reference acceleration processes or reference braking processes and taken into account when determining the evaluation result. In order to be able to evaluate a braking process or an acceleration process performed in a respective driving situation as accurately as possible, correspondingly precise reference data is required.Based on the route the vehicle is traveling on, the specific driving situation, and the vehicle's position, a suitable acceleration or braking process can be searched for or determined in the reference data to be used for comparison. This can be used, for example, with a positioning unit such as GPS or GNSS. Map data and / or navigation data can then be used to determine the route, section of route, or route currently being traveled by the vehicle. In this case, characteristics can be determined based on the information on the route and the vehicle's position, which can then be used to determine or search for the appropriate reference acceleration or braking processes.

[0035] In one embodiment, further evaluation results relating to the driving behavior of other vehicles are provided to the evaluation device, wherein the determined evaluation result of the vehicle is compared with the further evaluation results. This is advantageous in order to be able to make an assessment, in particular a system-based assessment, as to whether the driving behavior of the vehicle or of the user of the vehicle is good or bad, or positive or negative. A wide variety of information from other vehicles and their drivers can be used in this process in order to be able to make a precise assessment of the driving behavior of the vehicle. Based on the driving behavior of the other or further vehicles, for example, the plausibility of or control of the own evaluation result can be carried out.

[0036] In addition to or instead of this, the evaluation device can generate a ranking of the compared evaluation results. This is particularly advantageous for fleet vehicles, car-sharing providers, or other service providers, as a driver of a vehicle in such a fleet can compare their driving style with other driving styles. This can, in turn, be used to raise awareness or as a learning outcome for the individual driver. This ranking can, for example, be displayed to the vehicle user on the electronic output unit or a mobile device.

[0037] A further aspect of the invention relates to an electronic evaluation system with an evaluation device, wherein the electronic evaluation system is designed to carry out a method according to the previous aspect or an advantageous development thereof. In particular, the previously described method or an advantageous development thereof can be carried out with the described electronic evaluation system.

[0038] The electronic evaluation system can, for example, be integrated as an electronic device in a vehicle. It is also conceivable for the electronic evaluation system to be a distributed system, so that the electronic evaluation system is at least partially external to a vehicle and, in turn, is connected to the vehicle via communication technology.

[0039] For example, the electronic evaluation system can be designed as a backend or cloud or data cloud.

[0040] A further aspect of the invention relates to a vehicle with an electronic evaluation system. Thus, with the aid of the evaluation system, appropriate evaluations or analyses can be performed in the vehicle, and these evaluation results can be displayed to the vehicle's passengers, in particular the driver, and / or transmitted to the vehicle's system.

[0041] The vehicle can be, for example, a motor vehicle, motor car, passenger car or truck.

[0042] In particular, the vehicle may be a highly automated vehicle, such as a partially autonomous or fully autonomous vehicle. A manual vehicle may also be provided.

[0043] Advantageous embodiments of one aspect of the invention are to be regarded as advantageous embodiments of all other aspects and vice versa.

[0044] For use cases or application situations that may arise during the method and which are not explicitly described here, it may be provided that, in accordance with the method, an error message and / or a request to enter user feedback is issued and / or a default setting and / or a predetermined initial state is set.

[0045] The means of transport according to the invention is preferably designed as a motor vehicle, in particular as a passenger car or lorry, or as a passenger bus or motorcycle or as a ship or as an aircraft or as a ferry.

[0046] The invention also includes further developments of the electronic evaluation system according to the invention and the vehicle according to the invention, which have features already described in connection with the further developments of the method according to the invention. For this reason, the corresponding further developments of the electronic evaluation system according to the invention and the vehicle according to the invention are not described again here.

[0047] The invention also includes combinations of the features of the described embodiments.

[0048] Exemplary embodiments of the invention are described below. Shown are: Fig. 1 an exemplary representation of a vehicle 1 during a driving situation, whereby an evaluation of the driving behavior carried out there is carried out; and Fig. 2 another example of a further driving situation of the vehicle Fig. 1 when approaching a traffic light.

[0049] The exemplary embodiments explained below are preferred exemplary embodiments of the invention. In the exemplary embodiments, the described components each represent individual, independently considered features of the invention, which also further develop the invention independently of one another and are thus also to be considered as components of the invention, either individually or in a combination other than that shown. Furthermore, the described exemplary embodiments can also be supplemented by further features of the invention already described.

[0050] In the figures, functionally identical elements are provided with the same reference numerals.

[0051] In the Fig. 1 schematically illustrates, by way of example, a vehicle 1 performing a journey 2. The vehicle 1 may be traveling in real traffic. For example, the vehicle 1 may be an at least partially autonomous vehicle or a fully autonomous vehicle. In order to operate the vehicle 1 in the most energy-efficient and environmentally friendly way possible, an efficient driving style is advantageous. In order to take this into account when driving the vehicle 1 or when subsequently driving the vehicle 1 or other vehicles, an evaluation or assessment of the driving behavior or driving style can be performed.

[0052] In order to evaluate driving behavior accordingly, specific driving situations can be analyzed during the journey 2. These driving situations can include, in particular, braking or acceleration, as these influence the energy consumption and CO2 emissions of vehicle 1. Other influencing factors such as steering interventions, lateral acceleration, or other vehicle conditions of vehicle 1 can also be considered.

[0053] For this purpose, an acceleration or braking process performed in a particular driving situation can be recorded. A recording device 3 can be provided for this purpose. This can be arranged in and / or on the vehicle 1 and, for example, can have distributed sensors.

[0054] In the Fig. 1 illustrates a conceivable driving situation 4 by way of example. Here, the vehicle 1 is traveling on a section of a route 5, in particular a predetermined route, during the journey 2. Depending on the previous situation, a braking or acceleration process of the vehicle 1 can be carried out or performed in this driving situation 4. A correspondingly detected acceleration process or a correspondingly detected braking process of the driving situation 4 can be transmitted to an evaluation device 6 after detection by the detection device 3. The evaluation device 6 can be an electronic processing unit and, in turn, a component of a higher-level electronic evaluation system 7.

[0055] For example, the rating system 7 can, contrary to the representation in the Fig. 1 can be external to the vehicle 1, and the evaluation device 6 can be integrated in the vehicle, and the device 6 and the system 7 can be connected to one another via communication technology. The recorded acceleration process or the recorded braking process can in turn be referred to as actual values, which in turn can be compared with target values ​​in order to evaluate or assess the driving behavior, for example in this driving situation 4. In this regard, the evaluation device 6 can be provided with reference acceleration processes and reference braking processes relating to various driving situations. These reference values ​​or reference processes can in turn be stored in a database 8. For this purpose, corresponding reference acceleration processes or reference braking processes from a wide variety of vehicles, such as fleet vehicles, can be stored or filed in the database 8.These can, in turn, be retrieved by the evaluation device 6. For the subsequent evaluation, the evaluation device 6 can, in turn, have an electronic evaluation unit 9. In order to evaluate the driving behavior, an evaluation result can be generated or produced. This is done, in particular, by the evaluation device 6. For this purpose, the recorded acceleration process as the actual acceleration process or the recorded braking process as the actual braking process can be compared with a respective reference process, i.e., a reference braking process or a reference acceleration process. Thus, a system-side target-actual comparison is performed.

[0056] In order to better evaluate the respective driving situation 4 with regard to driving behavior, environmental information relating to an environment 10 of the vehicle 1 can be recorded with the aid of the recording device 3. It is also conceivable that corresponding environmental information or other information relating to the driving situation 4 is provided or transmitted to the evaluation device 6 by an information source 11 external to the vehicle.

[0057] With the help of the environmental information, as described in the Fig. 1 is shown by way of example as a conceivable driving situation 4, information relating to an existing speed limit 12 and / or information relating to an existing safety distance 14 is provided to a vehicle 1 and another vehicle 13 traveling ahead of the vehicle 1. In other words, the evaluation or comparison relating to the acceleration or braking process can now be carried out to determine whether, for example, the safety distance 14 to the vehicle 13 traveling ahead is maintained during a braking process. If this safety distance 14 is not maintained, this is negative driving behavior, as it can lead to rear-end collisions in particular. If an acceleration process is carried out here, the evaluation also takes into account whether the existing or specified speed limit 12 is maintained.Excessive acceleration and thus excessive speed increase energy consumption and increase CO2 emissions.

[0058] The evaluation result generated or produced by the evaluation device 6 can, on the one hand, be output to a user 15 of the vehicle 1, i.e., a driver of the vehicle 1. For this purpose, the output can be made using an electronic output unit 16 in the vehicle 1. An infotainment system of the vehicle 1 can be used here. It would also be conceivable for the evaluation result to be output to a mobile device 17 of the user 15. By outputting the evaluation result with regard to driving behavior, the user 15 can, for example, be motivated or inspired to adapt their driving behavior. Thus, the user 15 can attempt to improve their driving behavior by independently accelerating or braking, by adapting braking or acceleration processes to reference acceleration or braking processes.It would also be conceivable that if the user 15 adopts a driving style or driving behavior that is energy-saving and environmentally friendly, the user 15 can be evaluated using a points system. Using this points system, the user 15 can collect points for positive driving behavior and lose points for negative driving behavior. This can be output to the user 15 via the output unit 16 or the mobile device 17 during the journey 2 without having to do so after the journey 2. The user 15 can thus improve their driving behavior and, in particular, receive feedback regarding the driving style or driving behavior. In other words, a "score gain" can be provided to the user 15 so that the user 15 can learn in a playful way how they should perform braking or acceleration operations in order to operate the vehicle 1 efficiently.

[0059] For this purpose, at least one piece of recommended adaptation information can be generated based on the evaluation result using the evaluation device 6 and, in particular, the electronic evaluation unit 9, and can then be output to the user 15 acoustically, visually, or haptically. This recommended adaptation information can be used to suggest to the user 15 how and to what extent they should change their driving behavior or driving style in order to achieve efficient operation of the vehicle 1.

[0060] The display of the evaluation result and in particular the presented evaluation scheme can be activated or deactivated by the user 15, for example before the start of the travel journey 2 or during the travel journey 2.

[0061] Furthermore, it is conceivable that the evaluation system 7 contains an application, which can be implemented, for example, on the mobile device 17. By means of this application or "app," statistics, histories, or other evaluations can be made available to the user 15. In this case, for example, an automated function can calculate how much energy or how much CO2 the user 15 has generated through their driving behavior. Likewise, it can be determined how much energy or how much CO2 the user 15 has saved through, for example, adapted driving behavior. It is also conceivable to display how the savings in terms of energy and CO2 would result if the user 15 were to change their driving behavior based on the evaluation result. In this way, the user 15 can be provided with a corresponding outlook or a predictive evaluation.

[0062] For an improved evaluation of driving behavior, a respective deviation or discrepancy can be determined between a recorded acceleration process and a corresponding reference acceleration process, or between the recorded braking process and a corresponding reference braking process. This occurs during the comparison using the evaluation device 6. Accordingly, the extent of the deviation and in particular the size of the deviation can be an indicator of whether or not the driving style saves energy and is more emission-efficient. Depending on the size of the deviation, the user 15 can be given appropriate information about it during the journey 2, for example, in order to adapt the driving behavior. If the deviation is small, this can be given to the user 15 after the journey 2 as feedback for future journeys.

[0063] Using the evaluation results and, in particular, the determined deviations, graphical representations and / or statistical representations can be generated. For this purpose, for example, the user 15 can be shown a graphical representation of the optimal braking and acceleration processes and the actual braking or acceleration processes in a graph, so that the user 15 can achieve corresponding learning success by implementing this accordingly during the travel journey 2 or during a future travel journey 2. An evaluation of the graph can show the user 15 at which times the user 15 drove close to an optimal curve and at which times they should have braked or accelerated more strongly, for example, in order to simplify the learning success of the user 15.

[0064] In order to be able to provide a suitable reference regarding the braking or acceleration process of the driving situation 4 or regarding a respective driving situation 4, certain characteristics are required in order to be able to find corresponding references. For this purpose, information regarding the route 5 and / or a current position 18 of the vehicle can be determined or provided according to the driving situation 4. Based on this information regarding the route on which the vehicle 1 is moving and / or the position, such as the GPS information, of the vehicle 1, suitable reference data, for example from the database 8, can be retrieved by the evaluation system 7 in order to be able to take this into account in the evaluation or comparison.

[0065] Furthermore, it is conceivable that, based on the evaluation result, information is provided or transmitted to at least one vehicle system 19 or a vehicle component or a vehicle function of the vehicle 1. This is particularly important for driver assistance systems or vehicle guidance systems, since a mechanical or system-based adaptation of the driving behavior can be carried out here. For this purpose, a corresponding electronic signal, such as an adaptation signal, can be generated with the aid of the evaluation device 6 in order to thereby be able to control or adapt or adjust the at least one vehicle system 19. As a further possibility for making the driving behavior and any necessary adaptation of the driving behavior more understandable to the user 15, the consideration of further driving behavior of other vehicles 20, such as fleet vehicles, can be used.In this case, a comparison can be made between different drivers or between different vehicles, so that, for example, the user 15 can compare how his behavior compares to other drivers. It would also be conceivable to generate a ranking of different drivers based on evaluation results, so that the different drivers are in competition with each other and thus energy consumption and / or emissions can be prevented. For example, a scoring system regarding sustainability or a scoring system regarding safety can be carried out. Thus, for example, the user 15 can be motivated through a playful approach to minimize energy and CO2 emissions. Thus, a sustainable and safe journey 2 can be achieved.

[0066] In this case, special reward functions are also advantageous, which in turn provide the user with greater motivation. In the following Fig. 2 is based on the above-mentioned statements of the Fig. 1 illustrates another driving situation 4. Here, vehicle 1 is approaching an intersection with a traffic light 21, such as a traffic light. In such situations, i.e., when approaching a traffic light, energy can be saved by adjusting the acceleration or braking process. For this purpose, information regarding the remaining duration of the respective traffic light phase, i.e., a red or green phase, can be displayed.

[0067] In this shown phase of driving situation 4 in the Fig. 2, when approaching traffic light system 21, this can be detected by means of detection device 3. Furthermore, information about the remaining duration of the traffic light phase can be provided to evaluation system 7 via a communication link from traffic light system 21 or a higher-level traffic control system. For example, a traffic light system such as a "Car-2-Traffic-Light" system can be used here. The information obtained can be displayed, for example, on a head-up display and made accessible to user 15. Based on the current speed and the remaining duration of the traffic light phase, an optimal acceleration or braking process can be calculated, resulting in minimal energy consumption. The calculated optimal acceleration or braking behavior can be output as a recommendation by user 15.Furthermore, a selection option can be provided here so that optimal acceleration or braking processes are carried out using a cruise control-like assistance system. For example, the vehicle system 19 can be used for this purpose. Furthermore, if the vehicle 1 is a fully autonomous vehicle, the corresponding information regarding the traffic signal system 21 can be provided to a vehicle guidance system in order to be able to carry out appropriate braking or acceleration processes. Furthermore, by combining the information about the remaining duration of the traffic signal system 21 with further information, such as information about traffic density, for example from cell phone signals of other road users, the optimal route can be recalculated or identified. Possible routes are checked for current traffic light and waiting phases.At any point where an alternative route can be taken, current traffic light phases and waiting times at the corresponding traffic light systems along the route are checked. Based on this, the route can be optimized for desired characteristics, such as time and / or emissions.

[0068] Furthermore, the aforementioned "Score Game" can be used. Here, the user 15 can be taught how to implement the optimal acceleration or braking behavior before the traffic light 21 by independently accelerating or braking. They can receive points depending on how close they have come to the destination. A ranking list can also be provided for this purpose in order to motivate the user 15 accordingly. Based on recorded information regarding the approach to the traffic light 21 and various remaining times of a respective traffic light phase, a preliminary analysis can be carried out at any traffic light 21 to determine how long or at what time acceleration or braking should be performed. This can be continuously learned by the evaluation system 7, for example, and taken into account accordingly.For example, information regarding the remaining duration of the traffic light phase can be output to the user 15 on a head-up display as output unit 16. Based on the information transmitted by the traffic light system 21, an optimized braking or acceleration recommendation can be generated. This can be done, for example, using the adaptation recommendation information. This, in turn, can be output to the user 15 via the output unit 16, and the user 15 can decide for themselves via an electronic input unit whether or not to follow this recommendation. Likewise, the user 15 can activate the vehicle system 19 to consider or use these recommendations.

[0069] By evaluating the various driving situations 4, not only the above-mentioned versions in the Fig. 1 and Fig.2 Recommendations or evaluations are not made, but rather, based on the respective evaluated driving situations, an optimal route or an optimized path along a planned route can be determined. A V2X infrastructure can optionally be used for this purpose.
