- the evaluation result can advantageously be provided to the output interface as a binary signal by the respective output signal.
- the position of the vehicle is preferably continuously determined using the position sensor and provided to the evaluation unit. Alternatively, the The position of the vehicle must be determined separately for each assessment. The position is preferably determined using a position sensor that is already present in the vehicle.
- a possible maneuvering option could be increasing or reducing the speed of the vehicle or turning the vehicle to the right or left.
- maneuvering options may include:
- the assessment of the respective maneuvering option is advantageously carried out on the basis of the respective admissibility according to the applicable traffic regulations.
- the decision logic is advantageously based in its structure on the traffic regulations. The structure can be changed, for example if traffic regulations change.
- the decision logic is advantageously designed in such a way that the assessment can be carried out on the basis of the traffic regulations.
- the traffic rules arise from the Road Traffic Regulations (StVO) or the Road Traffic Act (StVG).
- the assessment is preferably carried out in such a way that it determines whether the respective maneuvering option is permissible (“allowed”, positive) or not (“prohibited”, negative) according to the currently valid traffic regulations. It is advantageous to only evaluate the possible and/or requested maneuvering options of the vehicle. This means that only a reduced number of maneuvering options need to be evaluated by the decision logic.
- the decision logic can be designed as a neural network, a decision tree, a Boolean decision logic or as another structure, e.g. a decision ontology.
- the decision logic is advantageously deterministic.
- the decision logic can advantageously carry out the evaluation of a large number of maneuvering options in a simple manner.
- the evaluation result can be provided by the evaluation unit of a vehicle control system, which can make a decision regarding the maneuvering option based on the evaluation result.

- the invention described here can be used to develop the decision logic and thus the evaluation unit simply and with little computing power.
- a position sensor in particular a GPS sensor, is provided to provide the position.
- the position can be determined based on the use of a mobile network.
- a vehicle already includes a GPS sensor to record the position of the vehicle, such as a navigation system.
- a GPS sensor is advantageous because determining the position is particularly easy and can be determined precisely.
- the decision logic is based on a Boolean decision logic.
- a Boolean decision logic comprises a number of logic components and is therefore well suited to quickly and easily evaluating a number of input signals into an output signal.
- the maneuvering options can advantageously be represented as a binary code.
- the evaluation can also advantageously be represented as a binary code (Yes, No / 0, 1 / or Y, N).
- the respective maneuvering option can be represented in a binary code as follows (here simplified for an overtaking maneuver):
- the binary code provided to the decision logic can advantageously be designed according to (Yes, No, No, Yes, %) or (1,0,0,1,).
- the respective logic module is advantageously designed as a software module.
- the decision logic is advantageously designed as a software module.
- the decision logic is advantageously changeable so that the decision logic can be adapted to changing traffic regulations.
- the decision logic can advantageously be changed, in particular updated, via the BUS system.
- a Boolean decision logic enables a particularly quick evaluation.
- only a sub-area of the decision logic is activated at any one time, with the sub-area being selected based on the position of the vehicle.
- the decision logic can advantageously be restricted in its scope or functionality. The restriction is advantageously limited in time and/or dependent on the position of the vehicle.
- the decision logic is not relevant for most decisions.
- the question of parking is usually not relevant for a vehicle's position on a motorway or country road. Since an evaluation of such a maneuvering option is not to be expected, only the relevant part of the decision logic can be activated.
- the selection of the respective sub-area of the decision logic takes place in at least a first stage and a second stage.
- the decision logic can be further reduced based on the recorded environment of the vehicle. For example, if a lane is detected as being blocked and the blockage is indicated by an obstacle, a lane change to the blocked lane is not taken into account. The scope of the decision logic can therefore be further reduced.
- a reduced number of maneuvering options are provided for evaluation depending on the position of the vehicle.
- the required computing capacity can be reduced and/or the time for the evaluation can be reduced.
- the decision logic can be designed to be less complex from the start and thus a software-based solution of the decision logic can be operated with reduced memory requirements.
- the vehicle's surroundings take into account, for example, obstacles, other road users in the area or traffic signs as well as traffic lights or barriers in individual sections of traffic.
- the environment can be
- the environment is also advantageously provided by an environmental sensor.
- An environmental sensor is advantageously designed as a radar sensor, a LIDAR sensor or a camera.
- the environment detected by the environmental sensor is advantageously provided with the evaluation unit.
- the decision logic can be reduced in its function if the decision logic is only provided with the maneuvering options that appear possible given the vehicle's environment. In this case, only a small part of the decision logic needs to be active.
- an evaluation of the respective maneuvering possibility is provided in real time.
- a time period after which an output signal is available after the respective maneuvering option has been made available is, for example, 0.1 to 5 microseconds.
- a vehicle control system can also control the vehicle in real time. This means that such an evaluation unit can be used for autonomously driving vehicles.
- the vehicle comprises a position sensor, a control device and/or a BUS system and an evaluation unit as described above, wherein the position sensor is provided for providing the position of the vehicle and the evaluation unit is trained and intended to evaluate maneuvering options.
- the vehicle is advantageously designed as an automobile or as a rail vehicle.
- the vehicle is advantageously designed as a self-driving automobile or autonomously driving vehicle, so that the automobile can drive from a first position to a second position without a driver, without the need for driver assistance.
- An autonomously driving vehicle advantageously provides the respective maneuvering option to the evaluation unit with the help of its vehicle control.
- the respective maneuvering option is provided via the vehicle's bus system to the input interface of the evaluation unit.
- the respective maneuvering option to be evaluated can be provided by the vehicle control of a self-driving vehicle.
- the respective output signal can be provided again to the vehicle control of the self-driving vehicle.
- the respective maneuvering option can be provided by analyzing the driving behavior of a driver. For example, a planned lane change can be indicated by activating the corresponding indicator or by pressing the accelerator or brake pedal. Monitoring the driver's movements (changing the driver's line of sight) can also advantageously suggest a maneuvering option. The driver thus provides the respective maneuvering option.
- a signal e.g. a green light, can be displayed to the driver.
- Such a signal may include an acoustic signal, a light signal and/or a slight intervention in the steering/brake or in a staggered acceleration.
- the planned maneuvering option may not be available.
- the negative evaluation result is provided to the vehicle control system.
- the vehicle control system can then omit the maneuvering option.
- the vehicle advantageously includes at least one driver assistance application (ADAS system) such as a distance control assistant, a lane keeping assistant, and/or a brake assistant.
- ADAS system driver assistance application
- the environment is usually recorded with the help of this driver assistance application.
- the environment in particular the position of other road users and obstacles, is advantageously provided to the evaluation unit as the environment.
- the method is used to evaluate at least one maneuvering option of a vehicle, wherein the vehicle has an evaluation unit, in particular an evaluation unit as described above.
- the method comprises the following steps:
- the evaluation unit performs the evaluation depending on the position of the vehicle on the basis of a decision logic, wherein the decision logic is based on traffic rules which are valid at the respective position of the vehicle.
- the decision logic is advantageously based on the traffic rules that are relevant for the respective position of the vehicle, with the requirements and legal consequences (prohibited, permitted) being designed as input variables or output variables.
- the decision logic is advantageously designed in accordance with the traffic rules.
- the procedure enables a particularly simple and quick assessment of the respective maneuvering option, in other words the determination: permitted (Yes or Y) or prohibited (No or N).
- the at least one maneuvering option or a reduced number of maneuvering options can be specified, wherein the evaluation of the respective maneuvering options is based on of a respective sub-area of the decision logic, whereby the respective sub-area of the decision logic is limited to the evaluation of the maneuvering options specified or provided.
- the sub-area of the decision logic results from the relevant/possible maneuvering options. For example, on a motorway, the maneuvering options "parking on the right-hand side” or “increasing speed from 60 km/h to 80 km/h” are generally not evaluated, as these are either generally permitted or generally prohibited on most sections of a motorway. Accordingly, the decision logic can be reduced to a corresponding sub-area.
- the evaluation is based on a previously defined sub-area of the traffic rules, wherein the respective sub-area of the traffic rules can be determined based on the respective position of the vehicle.
- a speed limit may not be provided for in some areas on a German motorway and therefore an assessment of the maneuvering option “increasing the speed” would in any case be rated as “allowed” (or Yes or Y).
- a reduced decision logic to a sub-area of the decision logic also requires less storage space if the decision logic is designed as a software module.
- Environment sensor the environment of the vehicle and adjusts the environment to the Evaluation unit is available, whereby the respective maneuvering options can be determined based on the environment.
- An environment sensor is designed as a radar, LIDAR, ultrasound or camera sensor.
- the environment includes the possibility of where the vehicle can be maneuvered without colliding with obstacles or other road users.
- a reduced number of decision options are provided to the decision logic based on the environment. For example, if the vehicle changes lane (planned or intended) when another vehicle is present or a lane is blocked, no evaluation by the decision logic is required.
- an environmental sensor detects the environment of the vehicle and provides the environment to the evaluation unit, wherein the decision logic, in particular the defined sub-area of the decision logic, can be determined on the basis of the environment.
- the respective sub-area of the decision logic is dynamically adapted to the position of the vehicle and/or the surroundings of the vehicle, in particular when the position and/or the surroundings of the vehicle change.
- predeterminable sub-areas of the decision logic for typical positions of the vehicle can be stored in a memory and used accordingly to evaluate the respective maneuvering option.
- One possible application is an indication of whether an automatic parking aid for a vehicle is evaluating whether the vehicle is allowed to park at that spot at all and for how long.
- the parking aid provides the appropriate maneuvering option (e.g. parking on the right) to the evaluation unit.
- the evaluation unit is used to evaluate the maneuvering option and provides a positive or negative evaluation result depending on the position and optionally the surroundings of the vehicle. If parking at that spot is permitted according to the applicable traffic regulations, the parking process takes place - otherwise a warning signal may be provided.
- the position Pos of the vehicle 3 is also provided to the evaluation unit 1 by a position sensor 5.
- the position Pos is also advantageously provided via the BUS system 9.
- the decision logic 7 is used to evaluate B the maneuvering options M1, M2, M3 provided to it.
- the evaluation B is based on the position Pos of the vehicle 3.
- the evaluation B of the respective maneuvering options M1, M2, M3 of the vehicle 3 is carried out on the basis of the environment U of the vehicle 3, whereby the environment U of the vehicle 3 is provided by the environmental sensor 15 to the decision logic.
- the evaluation unit 1 shown here is designed for use in a vehicle 3.
- Such an evaluation unit 1 is advantageously designed as a software module which is installed on a computing unit (not shown) and can be run there. It is particularly advantageous if at least the decision logic 7 is designed as a software module and is installed on a computing unit and can be run there.
- Fig. 2 shows a vehicle 3 on a roadway.
- the vehicle is shown in the right lane (here as the lower lane).
- the vehicle 3 can perform at least three maneuvers M1, M2, M3.
- the first maneuvering option M1 represents a lane change of vehicle 3 into the left (upper) lane. Depending on the position Pos of vehicle 3, the first maneuvering option M1 can be assessed as “permitted” (compliant with traffic regulations) or “prohibited” (not compliant with traffic regulations) according to the traffic regulations.
- the second maneuvering option M2 represents driving the vehicle 3 straight ahead.
- the second maneuvering option M2 can be assessed according to the traffic regulations as “permitted” (compliant with traffic regulations, Y) or “forbidden” (not compliant with traffic regulations, N).
- the third maneuvering option M3 represents a turn to the right (downward). Depending on the position Pos of vehicle 3, the third maneuvering option M3 can be assessed as “permitted” (in compliance with traffic regulations) or “prohibited” (not in compliance with traffic regulations) according to the traffic regulations.
- the evaluation B using the evaluation unit 1 results in a positive evaluation result Y or a negative evaluation result N depending on the traffic regulations valid at the position Pos of the vehicle 3.
- the evaluation result Y, N is assigned to the vehicle 3 is provided.
- Fig. 3 shows possible sub-areas 7a of a decision logic 7.
- the decision logic 7 is reduced to a sub-area 7a based on the respective position Pos of the vehicle.
- the hatched area of the decision logic 7 is omitted.
- the hatched part of the decision logic 7 corresponds (figuratively speaking) to the part of the traffic rules that are not valid at the respective position Pos of the vehicle 3 (for example in town / position of the vehicle on a motorway) and would therefore always lead to a positive evaluation result Y.
- the sub-area 7a of the decision logic can be reduced in a second stage 13 based on the environment of the vehicle 3.
- the decision logic is reduced to a first sub-area 7a in relation to the traffic rule for the motorway. If the environment U of the vehicle 3 only has a limited maneuvering option M1, M2, M3, the decision logic can also be restricted accordingly in the second stage 13.
