[0002] Description

[0003] Method for controlling at least one vehicle system of a vehicle

[0004] The invention relates to a method for controlling at least one vehicle system of a vehicle according to the preamble of claim 1.

[0005] Mobile electronic devices carried by an operator, known as smart devices such as smartphones, tablet PCs, or smart glasses, are increasingly used to activate and / or control specific applications in vehicles, such as vehicle functions or systems. For example, in vehicles with a keyless entry system, such mobile electronic devices can control the vehicle's access function, thus locking and unlocking the vehicle doors.

[0006] To activate and / or control vehicle functions or systems via a mobile electronic device, communication signals in the form of a predefined communication protocol are transmitted between the vehicle-connected mobile electronic device and the vehicle using a suitable communication technology. Based on this communication protocol, and after final authorization by the vehicle, the vehicle function or corresponding vehicle system addressed by the mobile electronic device is then started or executed. However, this rather complex communication protocol results in a relatively long communication time between the mobile electronic device and the vehicle, especially if the relative position of the mobile electronic device in relation to the vehicle also needs to be determined.Consequently, the desired vehicle function or the corresponding vehicle system (202404716 2) can only be started or executed after a delay of typically several seconds.

[0007] The invention is based on the objective of providing a method for controlling at least one vehicle system of a vehicle according to the preamble of claim 1, in which the vehicle system can be started in a simple and reliable manner without significant delay.

[0008] This problem is solved by a method for controlling at least one vehicle system of a vehicle with the features of claim 1.

[0009] Advantageous further developments of the invention are part of the additional patent claims.

[0010] According to the invention, in the method for controlling at least one vehicle system of a vehicle, after establishing a communication link between the vehicle and a mobile electronic device carried by an operator and connected to the vehicle, a search intent signal or a range signal, for example a so-called range intent signal according to the Car Connectivity Consortium (CCC) certification system, is used to initialize at least one non-safety-related vehicle system of the vehicle during communication between the vehicle and the mobile electronic device. This search intent signal is transmitted from the mobile electronic device to the vehicle as the first communication signal during communication between the vehicle and the mobile electronic device.

[0011] Thus, certain non-safety-relevant vehicle systems or vehicle functions, and possibly all non-safety-relevant vehicle systems or vehicle functions, are already considered during the development of a 202404716 3

[0012] The communication link between the vehicle and the mobile electronic device is initiated as soon as the operator carrying the mobile electronic device connected to the vehicle enters a communication or connection area on the vehicle's exterior that enables communication between the mobile electronic device and the vehicle. Consequently, certain non-safety-relevant vehicle systems or functions, and potentially all non-safety-relevant vehicle systems or functions, are initiated even before the precise location of the mobile electronic device connected to the vehicle's exterior is determined.The search intent signal, which is transmitted from the mobile electronic device to the vehicle as the first communication signal within the framework of a communication protocol transmitted between the mobile electronic device and the vehicle, is transmitted from the mobile electronic device to the vehicle, in particular by means of Bluetooth communication technology, preferably the search intent signal is transmitted from the mobile electronic device to the vehicle by means of Bluetooth Low Energy communication technology (BLE).

[0013] The communication range or connection area in the vehicle's exterior, which enables the establishment of a communication link between the mobile electronic device and the vehicle, is therefore dependent on the range of the communication technology used to establish the communication link between the mobile electronic device and the vehicle. With the Bluetooth communication technology used in particular, and the Bluetooth Low Energy (BLE) communication technology preferably used for this purpose, the communication range between the mobile electronic device and the vehicle is between 10 m and 300 m, depending on the conditions in the vehicle's exterior. Consequently, the communication range or connection area also begins at a distance of 10 m to 300 m from the mobile electronic device.

[0014] Vehicle. Accordingly, the search intent signal is transmitted from the mobile electronic device to the vehicle at a certain distance from the vehicle.

[0015] In an advantageous embodiment of the invention, after the initialization of at least one non-safety-related vehicle system by the search intent signal, a preparation mode or preparatory operation, and thus a pre-functionality of the initialized non-safety-related vehicle system, is executed, and / or the normal mode or normal operation, and thus the normal functionality of the initialized non-safety-related vehicle system, is then executed. That is to say, after the start of the function, or at the start of the function of the respective non-safety-related vehicle system initialized by the search intent signal, either the normal mode is started, and thus the normal functionality of the respective non-safety-related vehicle system is executed.Or, after the start of the function, or at the start of the function of the respective non-safety-relevant vehicle system of the vehicle initialized by the search intent signal, a preparation mode preceding the normal mode is started, and thus a pre-functionality of the respective non-safety-relevant vehicle system of the vehicle is executed, to which the normal mode of the respective non-safety-relevant vehicle system of the vehicle can then be started if necessary, and thus the normal functionality of the respective non-safety-relevant vehicle system of the vehicle can be executed.Thus, upon receiving the search intent signal from the vehicle, either the respective non-safety-related vehicle system can be fully started and executed, or the respective non-safety-related vehicle system can be only partially started and executed, or the respective non-safety-related vehicle system can be started and executed in preparation for normal mode. 202404716 5.

[0016] Consequently, the execution of normal functionality in the normal mode of an initialized non-safety-relevant vehicle system can either occur directly after its initialization, or the execution of normal functionality in the normal mode of an initialized non-safety-relevant vehicle system may only occur after the execution of a pre-functionality in the preparatory operation of this non-safety-relevant vehicle system.

[0017] In a further advantageous embodiment of the invention, the activation of the preparation mode and the subsequent execution of the pre-functionality of the respective non-safety-related vehicle system, and / or the activation of the normal mode and the subsequent execution of the normal functionality of the respective non-safety-related vehicle system, are performed depending on an assessment of the probability of the operator carrying the mobile electronic device gaining access to the vehicle. Thus, the activation of the preparation mode and the subsequent execution of the pre-functionality of an already initialized non-safety-related vehicle system can be linked to a specific probability that the operator carrying the mobile electronic device intends to gain access to the vehicle.In particular, however, the start of normal mode and the subsequent execution of normal functionality of a non-safety-relevant vehicle system, which has already been initialized by the search intent signal and is in a preparatory mode with a pre-functionality, is linked to a certain probability that the operator carrying the mobile electronic device wishes to gain access to the vehicle.

[0018] To assess the probability that the operator carrying the mobile electronic device wishes to gain access to the vehicle, the distance of the operator carrying the mobile electronic device to the vehicle can be determined and / or the 202404716 6

[0019] The direction of movement of the operator carrying the mobile electronic device in relation to the vehicle is determined and / or the trajectory of the operator carrying the mobile electronic device in relation to the vehicle is determined.

[0020] The probability of an operator gaining access to the vehicle can be assessed, for example, using several stages. In particular, the activation of the preparation mode and the subsequent execution of the pre-functionality of the respective non-safety-relevant vehicle system, and / or the activation of the normal mode and the subsequent execution of the normal functionality of the respective non-safety-relevant vehicle system, can only occur once a predefined probability value for the operator carrying the mobile electronic device has been reached.In particular, this allows the normal mode of a non-safety-relevant vehicle system to be started in preparation mode with a pre-functionality, based on an assumption made by the mobile electronic device regarding the distance of the operator carrying the mobile electronic device to the vehicle and / or regarding the direction of movement of the operator carrying the mobile electronic device towards the vehicle.This means that when the operator carrying the mobile electronic device reaches an activation area, or when there is a clear direction of movement of the operator carrying the mobile electronic device towards the vehicle, the normal mode of the vehicle's non-safety-relevant vehicle system is started and thus the normal functionality of the vehicle's non-safety-relevant vehicle system is executed.

[0021] Preferably, a respective non-safety-relevant

[0022] The vehicle's system is assigned a configurable and therefore individual probability value. Thus, the start of the function of 202404716 7 is also

[0023] Preparation mode and thus the execution of the pre-functionality of the respective non-safety-relevant vehicle system of the vehicle initiated by the search intent signal and / or the start of the normal mode and thus the execution of the normal functionality of the respective non-safety-relevant vehicle system of the vehicle initiated by the search intent signal and possibly in a pre-functionality state, depending on the probability of access to the vehicle by the operator carrying the mobile electronic device, can be individually configured for the respective non-safety-relevant vehicle system of the vehicle.For example, the normal mode function for executing the normal functionality of a non-safety-related vehicle system with high energy consumption or a non-safety-related vehicle system with a short startup time can only be initiated if there is a high probability that the operator carrying the mobile electronic device will access the vehicle. Conversely, the normal mode function for executing the normal functionality of a non-safety-related vehicle system with low energy consumption or a non-safety-related vehicle system with a long startup time can be initiated even with a low probability that the operator carrying the mobile electronic device will access the vehicle.For example, a vehicle navigation system that requires a long startup time and is initialized by the search intent signal can be started in normal mode to execute the normal functionality of the vehicle's navigation system even with a low probability value for the operator carrying the mobile electronic device accessing the vehicle.

[0024] In a further advantageous embodiment of the invention, the search intent signal is transmitted from the mobile electronic device to the vehicle using Bluetooth communication technology. This is particularly useful when the vehicle carrying the mobile electronic device is approaching. 202404716 8

[0025] Further communication signals between the mobile electronic device and the vehicle, transmitted to the operator, are preferably transferred from the mobile electronic device to the vehicle using ultra-wideband communication technology. Ultra-wideband communication technology (UWB) enables highly precise determination of the distance between two objects. In particular, ultra-wideband communication technology can also determine the location of another device using ultra-wideband communication technology with centimeter accuracy.This process utilizes ultra-wideband communication technology to measure the distance between the mobile electronic device and the vehicle, and / or to locate the mobile electronic device relative to the vehicle, and / or to measure the direction of movement of the mobile electronic device relative to the vehicle. The evaluation of the communication signals between the mobile electronic device and the vehicle is performed primarily by determining the time of flight (TOF) of the communication signals. This involves measuring the time of flight, specifically a so-called TOF measurement, of the communication signals between the mobile electronic device and at least one transceiver located on or in the vehicle.Preferably, a time-of-flight measurement is performed between the mobile electronic device and several transmit-receive units arranged on the vehicle, i.e., on the outside of the vehicle or inside the vehicle, i.e., in the interior of the vehicle.

[0026] In a preferred embodiment, the method is used to control a vehicle lighting system as a non-safety-relevant vehicle system, and in particular, this lighting system is used to create a lighting display for the vehicle's exterior. 202404716 9

[0027] In the preparation mode of the vehicle's initialized lighting system, the system performs a preliminary function: the vehicle's entire perimeter is illuminated using its exterior lights. In the subsequent normal mode, the system's normal function is to illuminate the vehicle door that the operator carrying a mobile electronic device approaches when they approach. In other words, after the vehicle's lighting system is initialized, the entire area surrounding the vehicle is illuminated.Subsequently, when the operator approaches the vehicle, the vehicle's lighting is restricted to the area on the exterior of the vehicle that is closest to the operator carrying the mobile electronic device and approaching the vehicle, or towards which the operator's direction of movement or trajectory leads. Specifically, the vehicle's exterior lighting is then restricted to the vehicle door that is closest to the operator carrying the mobile electronic device and approaching the vehicle, or towards which the operator's direction of movement or trajectory leads.Consequently, when an operator approaches the vehicle as the driver and carries a mobile electronic device, the vehicle is illuminated, in particular, on the outside of the vehicle in a specific area around the driver's door, or the driver's door itself is illuminated.

[0028] For the transmission of communication signals between the vehicle and the mobile electronic device carried by the operator and coupled to the vehicle, a communication system also claimed according to the invention is preferably provided. This communication system for controlling the execution of the method according to the invention can include an evaluation unit, a control unit, or a control module in the vehicle, which can in particular be designed as a vehicle control unit. The control unit or evaluation unit provided for controlling the communication system, or the control unit or control module provided for controlling the communication system, can include a data processing device or a processor unit configured to perform one of the described features of the invention.The processor device can comprise at least one microprocessor and / or at least one microcontroller and / or at least one FPGA (Field Programmable Gate Array) and / or at least one DSP (Digital Signal Processor). In particular, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), or an NPU (Neural Processing Unit) can be used as the microprocessor. Furthermore, the processor device can comprise program code configured to execute one of the described features of the invention when executed by the processor device. The program code, including the program instructions, can be stored in a data memory of the processor device. The processor device can, for example, be integrated on at least one circuit board and / or on at least one SoC (System on Chip).

[0029] Thus, to carry out the described process steps of the method according to the invention, a processor circuit comprising at least one microprocessor and / or microcontroller can be provided, which has a program or software comprising program instructions which, when the program instructions are executed, causes the processor circuit to carry out an embodiment of the method.

[0030] Furthermore, the invention also claims a vehicle comprising a communication system and at least one transmit-receive unit and at least one non-safety-related vehicle system. The invention thus also includes such a vehicle, which may be designed in particular as a motor vehicle or motor car, especially as a passenger car, or as a truck or as a passenger bus.

[0031] Furthermore, the invention also includes combinations of the features of the described embodiments.

[0032] Advantageously, in the method according to the invention, a respective non-safety-related vehicle system is initialized simply and reliably without time delay and started at least in a preparation mode to execute a preliminary function, and optionally also in normal mode to execute the normal function. This allows the functionality of a non-safety-related vehicle system to be executed without significant time delay when an operator approaches the vehicle, during the automatic selection and initialization of such a system.

[0033] An embodiment of the invention is described in more detail below with reference to the drawing. The drawing shows:

[0034] Fig. 1 shows a schematic representation of a vehicle and its surroundings as a driver approaches the vehicle;

[0035] Fig. 2 shows a schematic representation of a vehicle and its surrounding area as a driver approaches the vehicle.

[0036] The embodiment described below is a preferred embodiment of the invention. In this embodiment, the described components each represent individual features of the invention that can be considered independently of one another, which 202404716 12

[0037] The invention can be further developed independently of one another and thus can also be considered as a component of the invention individually or in a combination other than that shown. Furthermore, the described embodiment can also be supplemented by further features of the invention already described.

[0038] In the figures, functionally identical elements are each provided with the same reference symbols.

[0039] A control system according to the invention for a non-safety-related vehicle system can be implemented, for example, in a vehicle telematics system. When a person carrying a mobile electronic device reaches a communication or connection area, the telematics system is automatically initialized or activated by a search intent signal to check whether new software for the vehicle, and thus for at least one vehicle system, is available on a server as part of an update. This allows available, up-to-date software to be provided to the vehicle at an early stage and installed in at least one vehicle system.

[0040] Furthermore, a control according to the invention of a non-safety-relevant vehicle system of the vehicle can be carried out in a so-called polling system of the vehicle, wherein the polling system is initialized or started by the search intent signal when a communication area or connection area is reached by an operator carrying the mobile electronic device, in order to carry out a cyclic search for an electronic key that enables access to the vehicle.

[0041] In addition, a control according to the invention of a non-safety-relevant vehicle system of the vehicle can be carried out in a navigation system of the vehicle, wherein the navigation system is initialized or started by the search intent signal when a communication area or connection area is reached by an operator carrying the 202404716 13 mobile electronic device in order to quickly start up the navigation system.

[0042] Preferably, however, the control according to the invention of a non-safety-relevant vehicle system of the vehicle 1 is carried out by a lighting system 7 of the vehicle 1 for the lighting design of the vehicle 1, as shown in Figure 1 and Figure 2 of the drawing. In particular, this lighting design of the vehicle 1 is controlled by the lighting system 7 depending on the relative position of a driver 2 carrying a smartphone as a mobile electronic device 3 relative to the vehicle 1, and thus depending on the distance between the driver 2 and the vehicle 1, or depending on the direction of movement of the driver 2 relative to the vehicle 1. The smartphone 3 carried by the driver 2 is coupled to the vehicle 1 and is intended for communication with certain vehicle systems of the vehicle 1, in particular also for communication with an access system of the vehicle 1.

[0043] According to Figure 1, the driver 2, carrying the smartphone 3, enters the communication zone 4, from which a communication connection between the smartphone 3, paired with the vehicle 1, and the vehicle 1 can be established. This communication zone 4 begins at a distance between the driver 2 and the vehicle 1 that depends on the communication technology used, for example, at a distance of between 30 m and 100 m. After the communication connection between the smartphone 3 and the vehicle 1 has been established, communication signals 5 are transmitted using a specific communication technology. These communication signals 5 are transmitted and received by the vehicle 1 by one or more transmitter-receiver units 9 of a communication system 6.These transmit-receive units 9 can be arranged on the vehicle 1 202404716 14, that is, on the outside of the vehicle 1, or arranged inside the vehicle 1, that is, inside the vehicle 1.

[0044] After the communication connection between the smartphone 3 and the vehicle 1 is established, a search intent signal 15 is transmitted from the smartphone 3 to the vehicle as the first communication signal 5. This search intent signal 15 is transmitted from the smartphone 3 to the vehicle 1, for example, using Bluetooth Low Energy communication technology, and is received by at least one of the vehicle 1's transceiver units 9, for example, a transceiver unit 9 located in the rear area 12 of the vehicle 1.After receiving the search intent signal 15, a preparation mode of the vehicle 1's lighting system 7 is initiated by a control unit 17 of the vehicle 1. In this preparation mode, the vehicle 1's lighting system 7 is controlled to perform complete perimeter lighting 8 as a preliminary function. This means that the vehicle 1's lighting system 7 initially illuminates the entire vehicle 1 within a specific radius, including, in particular, the area around the driver's door 10 and the passenger's door 11.

[0045] According to Figure 2, after reaching the communication area 4, driver 2 subsequently also reached an activation area 13 upon further approaching vehicle 1. Driver 2's approach to vehicle 1, and thus the reaching of activation area 13, is determined based on the relative position and therefore the distance of driver 2, who is carrying the smartphone 3, to vehicle 1, and / or the direction of movement of driver 2 relative to vehicle 1. For this purpose, the communication signals 5 successively transmitted from smartphone 3 to vehicle 1 as localization signals 16 are evaluated. 202404716 15

[0046] These localization signals 16 are, for example, successively transmitted from the smartphone 3 to the vehicle 1 using ultra-wideband communication technology and received by several transceiver units 9 of the vehicle 1. For example, the localization signals 16 are received by four transceiver units 9 of the vehicle 1, such as a transceiver unit 9 of the vehicle 1 located in the rear area 12 of the vehicle 1, a transceiver unit 9 of the vehicle 1 located in the front area 18 of the vehicle 1, a transceiver unit 9 of the vehicle 1 located in the area of ​​the driver's door 10 of the vehicle 1, and a transceiver unit 9 of the vehicle 1 located in the area of ​​the passenger door 11 of the vehicle 1.In this distance measurement between the smartphone 3 and the four transceiver units 9 of the vehicle 1, the time of flight (TOF) of the localization signals 16, transmitted, for example, via ultra-wideband communication technology, is recorded and evaluated. By evaluating the different travel times of the localization signals 16 successively transmitted from the smartphone 3 to the individual transceiver units 9 of the vehicle 1, the position of the smartphone 3, and thus of the driver 2, relative to the vehicle 1 can be located very precisely based on these time-of-flight measurements. In particular, this also allows it to be determined from which side of the vehicle 1 the driver 2 is approaching the vehicle 1, that is, specifically whether the driver 2 is approaching the driver's door 10 of the vehicle 1 or whether the driver 2 is approaching the passenger door 11 of the vehicle 1.

[0047] If, by evaluating these runtime measurements, the position of the smartphone 3, and thus of the driver 2, relative to the vehicle 1 is located such that the driver 2, carrying the smartphone 3, has reached the activation area 13, a very high probability of the driver 2's desired access to the vehicle 1 is assumed. Upon the driver 2 reaching the activation area 13, and with the associated very high probability of the driver 2's access to the vehicle 1, the complete ambient lighting 8, implemented in a preparatory mode with a pre-functionality as shown in Figure 1, is specified as the lighting scheme of the lighting system 7. In normal operation, this is specified as door lighting 14, the normal functionality of the lighting scheme of the lighting system 7.Since in the example shown in Figure 2 the driver 2 approaches the driver's door 10 of the vehicle 1, a specification is therefore also made for a door light 14 of the driver's door 10 of the vehicle 1.

[0048] Due to the ambient lighting 8 of the vehicle 1, already executed in a preliminary function based on the search intent signal 15 as a light staging of the lighting system 7, and the subsequent door lighting 14 of the driver's door 10 of the vehicle 1 as the main function of the light staging of the lighting system 7, these functionalities of the lighting system 7 of the vehicle 1 can be started early without any time delays due to complex communication between the smartphone 3 and the vehicle 1.

[0049] Overall, the example shows how an inventive method for controlling a vehicle system of a vehicle can be provided in a simple manner and with advantageous properties by advantageous evaluation of communication signals transmitted between the mobile electronic terminal and the vehicle.
