Definitions
- the invention relates to a method for actuating an access system of a motor vehicle according to the preamble of claim 1.
- a method of the type mentioned is known from CN 210466502 U. It uses an ultra wideband unit to detect a person's approach to a vehicle as well as their position in front of a vehicle door. Furthermore, when the person has approached the vehicle close enough, the direction in which the person is looking is recorded by a camera and evaluated, with an access system of the motor vehicle being actuated when the person looks at the vehicle door.
- the disadvantage is that the motor vehicle has to be equipped with a relatively large number of expensive sensors in order to implement the method, so that the implementation of this method in a motor vehicle is associated with relatively high costs.
- the object of the invention is to specify a method that is improved over the known methods.
- a method for actuating an access system of a motor vehicle is proposed according to the invention, said motor vehicle being initially equipped with an access system for locking and unlocking the same and with an ultra-broadband unit hereinafter referred to as a UWB unit.
- the UWB unit is set up to operate as a UWB radar in a radar mode become. It is essential for the method that the UWB unit is operated in said radar mode and detects the position of a person approaching the motor vehicle and at the same time carries out a body position scan of this person in order to detect the body position of this person. In particular, an orientation of the face or head of this person and/or a viewing direction of the face or head of this person can be detected.
- the access system of the motor vehicle is actuated precisely when the person, in particular their head, looks in the direction of a vehicle door of the motor vehicle and/or when the person is within a predetermined distance from the vehicle.
- This makes it possible to either allow or deny a person access to the motor vehicle, depending on their body position and position relative to the motor vehicle.
- the location and position of a person approaching the motor vehicle can only be implemented using the UWB unit and further sensors on the motor vehicle, in particular cameras for face recognition, can be dispensed with.
- the method according to the invention can be implemented with relatively few components and can therefore be implemented relatively inexpensively in motor vehicles.
- the invention can also consist in providing a motor vehicle in which the method explained above is implemented.
- the motor vehicle is expediently set up to carry out the implemented method, for example using a control device installed in the motor vehicle.
- the invention expediently relates to a method for actuating an access system of a motor vehicle, which is equipped with an access system for locking and unlocking the motor vehicle and an ultra-broadband unit, hereinafter referred to as a UWB unit.
- the UWB unit is configured to operate in a radar mode. It is essential for the method that the UWB unit is operated in said radar mode and detects a position of a person approaching the motor vehicle and carries out a body position scan of this person in order to detect a body position of this person, in particular by the UWB unit an orientation of the face of this person is determined and/or a viewing direction of this person is determined.
- the access system is actuated precisely when this person looks in the direction of a vehicle door of the motor vehicle.
- FIG. 4 shows a section of a motor vehicle in a plan view.
- FIG. 1 shows any commercially available motor vehicle, designated overall by the reference number 1, which is equipped with a central UWB unit 2, symbolized here by a simple box, according to a first embodiment, and an access system 4 for locking and unlocking the motor vehicle 1.
- a person 3 also symbolized by a simple box, approaches the motor vehicle 1, with the UWB unit 2 carrying out the method according to the invention by being operated in radar mode, so that there is a position of the person 3 approaching the motor vehicle 1 and his body position continuously recorded.
- the access system 4 is actuated when the person 3 looks in particular with their head in the direction of a vehicle door of the motor vehicle 1 and/or is within a predetermined distance from the motor vehicle 1 .
- the UWB unit 2 and the access system 4 can, for example, communicate with one another via a control unit (not shown) of the motor vehicle 1 and can be controlled by the same.
- FIG. 2 shows another motor vehicle 1 with a UWB unit 2 according to a further embodiment.
- the present UWB unit 2 has six separate UWB modules 5, indicated by boxes, which are each set up to carry out the method according to the invention.
- the UWB modules 5 are set up, in particular, via UWB communication with a mobile terminal device carried by a person 3 authorized to use the motor vehicle 1, which is controlled, for example, by a so-called intelligent key (smart key) or a mobile phone (smartphone) or a so-called CoD , ie a smart device owned by the user of the motor vehicle (from the English consumer owned smart device), can be realized to communicate.
- UWB modules 5 are expediently set up to determine the position of the mobile terminal or that of said person 3 relative to motor vehicle 1 as part of the UWB communication with the mobile terminal of said person 3 .
- the UWB communication can be designed according to the guidelines of the consortium for vehicle connectivity (from the English “car connectivity consortium” aka “CCC”).
- the UWB modules 5 of the UWB unit 2 are set up to be operated in a radar mode, with computing chips of the UWB modules 5 in particular being set up in terms of radio technology for such a radar mode.
- the respective UWB modules 5 of the UWB unit 2 emit relatively short radio signals 6 in the UWB radio frequency spectrum, in particular a few nanoseconds long, symbolized by wavy lines in FIG.
- the UWB modules 5 can each be equipped with a transmission device 8 specially set up for this purpose.
- the UWB modules 5 of the UWB unit 2 work with pulsed radio signals, ie can be operated in a pulsed radar mode.
- each UWB module 5 of the UWB unit 2 operates as a receiver and detects backscattered echo radio signals 7 of the emitted radio signals, symbolized in FIG. 2 by wavy dashed lines.
- the UWB modules 5 can each have a receiver device 9 specially set up for this purpose. This makes it possible to use the UWB modules 5 of the UWB unit 2 to detect a position of a person 3 approaching the motor vehicle 1 and/or the body position of the person 3 relatively precisely.
- the access system 4 of the motor vehicle 1 can then be actuated, for example, so that the person 3 is granted access to the motor vehicle 1 if they are oriented towards the motor vehicle and/or are looking at the same.
- the UWB modules 5 of the UWB unit 2 which in particular implement a pulsed radar, expediently also include an internal system clock 10 and/or a pulse wave generator 11 and/or a radio signal amplifier and/or a wave delay detector 12 and/or a device 13 for classifying the orientation.
- the UWB unit 3 shows an optional flow chart of the method according to the invention. It shows the UWB unit 2 or a UWB module 5 set up for radar operation.
- the UWB unit 2/the UWB module 5 has a transmitting device 8 and a receiving device 9 indicated by boxes.
- the transmitting device 8 is supplied with an electrical control signal by an internal system clock 10 and a pulse wave generator 11 so that it can emit a radio signal 6 symbolized by an arrow, which is returned by a person 3 with a time delay as an echo radio signal 7 .
- the receiver device 9 detects the radio echo signal 7 and provides an electrical signal based thereon to a wave delay detector 12, which communicates with a device 13 for classifying the orientation of the person 3, so that the received radio echo signal 7 can be evaluated.
- FIG. 4 shows a section of a motor vehicle 1 which is equipped with a UWB unit 2 and/or UWB modules 5 (not shown) and set up for carrying out the method according to the invention. It is particularly important that a position and/or a body position and/or a line of sight 14 of the person 3 is detected by means of the UWB unit 2 and/or UWB modules 5 operated in radar mode. In order to ensure that the person 3 is only granted access to the motor vehicle 1 if it is actually oriented towards the motor vehicle 1 and/or looks at it, it is expedient for a classification circle 15 to classify the identified data within the scope of the method according to the invention Body position and / or line of sight 14 of the person 3 is provided.
- the access system 4 of the motor vehicle 1 is actuated in order to allow the person 3 access.
- Classification circle section 17 of the classification circle 15 falls, the access system 4 of the motor vehicle 1 is not actuated and access to the motor vehicle 1 is blocked.
