Description

[0001] The invention relates to a method for carrying out at least one driving scenario in a vehicle.

[0002] From US patent 11,605,306 B2, a method is known which relates to a training system with which a driver is trained on the occurrence of anomalous driving events of automated vehicle systems.

[0003] The invention is based on the objective of providing a method for carrying out at least one driving scenario in a vehicle that is improved compared to the prior art.

[0004] The problem is solved according to the invention by a method having the features of claim 1.

[0005] The inventive method for carrying out at least one driving scenario in a vehicle, wherein the driving scenario is based on a simulation and is carried out using at least one existing user interface in an interior of the vehicle, provides that after at least one simulation of the driving scenario has been carried out in the vehicle, at least one stage of an automated driving mode of the vehicle is activated.

[0006] A particular advantage of the invention is the possibility of simulating and optionally executing driving scenarios that are never or only rarely experienced in a vehicle. For example, the limits of vehicle modes and safety-relevant situations, such as a vehicle accident, can be simulated to train a user of the vehicle.

[0007] Additionally, the simulation and subsequent activation can reduce user errors in the vehicle and increase road safety. Furthermore, the user can be prepared for the system behavior of an automated driving mode and made aware of specific situations that may arise during its operation.

[0008] Advantageous embodiments of the invention are the subject of the dependent claims.

[0009] Exemplary embodiments of the invention are explained in more detail below with reference to drawings.

[0010] This shows: Fig. 1. Schematically, a simulation of a driving scenario in a vehicle by a user, and Fig. 2 schematically illustrates a procedure for carrying out a driving scenario.

[0011] Corresponding parts are marked with the same reference symbols in all figures.

[0012] Fig. Figure 1 schematically shows the execution of a simulation 9 of a driving scenario 1 in a vehicle 3 by a user 4.

[0013] The vehicle 3 includes, in particular, at least one user interface 5. The at least one user interface 5 is, for example, an instrument cluster, a display 5.1, a warning signal, a notification, and / or the like. For example, the user interface 5 is a user interface 5 already present in the vehicle 3, such as a touchscreen, controls, a display, or the like.

[0014] The at least one user interface 5 is located in an interior space 7 of the vehicle 3.

[0015] Driving scenario 1 is based, for example, on at least one simulation 9. Simulation 9 is stored and / or executed, for example, on a control unit of the vehicle 3 (not shown in detail). Simulation 9 can be activated, for example, via the user interface 5. Driving scenario 1 may include, for example, specific driving situations, limit situations of the vehicle 3's driver assistance systems, and / or transitions between a manual driving mode and an automated driving mode 10. Additionally, the vehicle 3 may contain a number of predefined driving scenarios 1, which are stored and retrievable, for example, in a memory location 12.

[0016] Simulation 9 of driving scenario 1 can, for example, be started and executed via at least one user interface 5 in the interior 7 of vehicle 3. Simulation 9 of driving scenario 1 is carried out by user 4, in particular, when vehicle 3 is stationary. For example, a corresponding algorithm can be implemented that only starts and executes simulation 9 when a stationary state, parking of vehicle 3, a switched-off engine of vehicle 3, or similar conditions are detected by appropriate sensors and fed into the algorithm. Driving scenario 1 is selected, for example, from the number of driving scenarios 1 using a random number generator 11.

[0017] Simulation 9 of driving scenario 1 is a prerequisite for unlocking a stage of automated driving mode 10 for vehicle 3. For example, vehicle 3 may be configured to unlock a stage of automated driving mode 10 only after the driver has successfully and / or completely completed simulation 9 of driving scenario 1. Specifically, vehicle 3 may reject a user 4 activation request for a stage of automated driving mode 10 if user 4 has not successfully and / or completely completed simulation 9 of driving scenario 1.

[0018] If user 4 wants to perform a simulation 9 of driving scenario 1 while vehicle 3 is stationary, a specific driving scenario 1 is randomly selected from the previously stored number of driving scenarios 1. Alternatively or additionally, user 4 can also be notified by vehicle 3 to perform a simulation 9 of driving scenario 1. The selected driving scenario 1 is, for example, a specific driving situation, such as an accident scenario involving vehicle 3.

[0019] During the execution of simulation 9 of driving scenario 1, the selected driving scenario 1 is displayed on at least one user interface 5.

[0020] In Fig. Figure 2 schematically illustrates a procedure for carrying out a driving scenario 1.

[0021] User 4 of vehicle 3 makes a request to activate an automated driving mode 10. Subsequently, it can be checked whether a request to activate automated driving mode 10 has been made for the first time and / or whether the simulation 9 of driving scenario 1 has already been carried out.

[0022] If no simulation 9 of driving scenario 1 has been carried out and / or a request to activate automated driving mode 10 has been made for the first time, the vehicle 3 can request the user 4 to first start and execute simulation 9 of driving scenario 1, which corresponds to automated driving mode 10.

[0023] The automated driving mode 10 is, for example, coupled or can be coupled with a sensor system 17. The sensor system 17 is specifically designed to monitor and / or analyze the environment of the vehicle 3 and / or the vehicle 3 itself when automated driving mode 10 is activated.

[0024] For this purpose, the random number generator 11 can select the relevant driving scenario 1 from the number of driving scenarios 1, which simulates the automated driving mode 10. Subsequently, the simulation 9 of driving scenario 1 is carried out in the interior 7 of the vehicle 3.

[0025] In particular, the simulation 9 of driving scenario 1 is carried out via the at least one user interface 5, specifically by displaying and / or acoustically outputting the results. For example, the display 5.1 can show a simulated drive of vehicle 3 as driving scenario 1.

[0026] Additionally, user 4 can control the running simulation 9 of driving scenario 1 in combination with steer-by-wire 13 (SbW) and drive-by-wire 15 (DbW). For example, user 4 can steer vehicle 3 in simulation 9 using steer-by-wire 13. For example, user 4 can accelerate, decelerate, and / or maintain a constant speed of vehicle 3 in simulation 9 using drive-by-wire 15. In particular, user 4 can recreate a real-world sequence of driving scenario 1 in simulation 9.

[0027] Steer-by-Wire 13 refers in particular to the mechanical decoupling of a steering wheel and steered wheels of the vehicle 3. Steering commands are evaluated by a sensor and electrically transmitted to an actuator, which executes the steering command.

[0028] Drive-by-wire 15 refers to the control of the vehicle 3 via an electrical connection. The position of the controls for the vehicle 3 is evaluated by sensors and electrically transmitted to at least one actuator, which executes the control of the vehicle 3.

[0029] If simulation 9 of driving scenario 1 has been successfully and / or completely completed, in particular one level of automated driving mode 10 will be automatically unlocked and made available to user 4. QUOTES INCLUDED IN THE DESCRIPTION
