Definitions
- a vehicle may be equipped with a digital access and/or control system that allows the user to use an electronic device, such as a smartphone with a digital key as a vehicle key and to use it to control one or more remote control functions of the vehicle.
- an electronic device such as a smartphone with a digital key as a vehicle key and to use it to control one or more remote control functions of the vehicle.
- the electronic device may be used to remotely control and/or monitor an automated parking maneuver of the vehicle.
- a device for providing a remote control function of a (motor) vehicle is described.
- the remote control function can include the automated longitudinal and/or transverse guidance of the vehicle.
- the remote control function can in particular include an automated parking maneuver of the vehicle.
- the remote control function can be controlled via a communication connection between the vehicle and a device (arranged outside the vehicle) for controlling the remote control function.
- the device can be a mobile and/or electronic (user) device of a user of the vehicle (such as a smartphone or a smart device).
- the device can comprise a digital key in accordance with a Car Connectivity Consortium, CCC, standard, in particular in accordance with the CCC Release 3 standard.
- the digital key can be designed to enable the device to control the remote control function of the motor vehicle.
- the communication connection can comprise, in particular be, a Bluetooth Low Energy (BLE) communication connection.
- BLE Bluetooth Low Energy
- the device can be set up to receive or send a message repeatedly, in particular periodically (e.g. every 100 ms), as part of the control communication between the device and the vehicle.
- the individual messages can each include control data for controlling the remote control function and/or quality data (e.g. the round trip time, RTT) for determining the quality of the communication connection.
- quality data e.g. the round trip time, RTT
- the device can be set up to check, as part of the control communication between the device and the vehicle, whether a received message is impaired or not. This can be done, for example, using a cyclic redundancy check (CRC).
- CRC cyclic redundancy check
- the device can also be set up to request a repeated transmission of the message if it is determined that the received message is impaired. This can result in a "retransmission" of a message.
- the repeated transmission of messages can be effected at a certain frequency (e.g. every 30ms). The robustness of the remote control of the remote control function of the vehicle can be increased by the repeated transmission of impaired messages.
- One or more interference sources in the vicinity of the vehicle and/or the device can cause the periodically sent messages to be affected, resulting in repeated transmissions of messages and thus further strain on the communication link. This can lead to an exponential increase in messages and a corresponding increase in time delays in the exchange of messages. This can ultimately lead to a termination of the remote control function (e.g. if the time delay exceeds a certain termination time).
- the device is set up to determine (during the execution and/or control of the remote control function of the vehicle, and/or before aborting the remote control function) that there is an impairment of the communication connection, in particular the control communication.
- the device can be set up (if necessary repeatedly) to determine one or more indications of an impairment of the communication connection, in particular the control communication. It can then be determined in a particularly precise manner on the basis of the one or more indications that there is an impairment of the communication connection, in particular the control communication.
- the one or more pieces of evidence may include
- a fill level of the data buffer for sending messages as part of the control communication in particular a fill level that is higher than a fill level threshold; it can be detected, for example, that the fill level of the data buffer (in particular due to "retransmissions") has accumulated up to or above the fill level threshold, which leads to relatively high time delays.
- the impairment of the communication connection in particular the control communication, can be detected before the remote control function is aborted.
- Such an abort can occur, for example, if a request message sent by a communication partner (eg the vehicle) is not answered by a response message from the communication partner even after a predefined abort period (eg 500ms or more, about 600ms) has elapsed.
- a predefined abort period eg 500ms or more, about 600ms
- the device is further configured to cause the remote control function and the control communication between the device and the vehicle to be interrupted in response to determining that there is an impairment of the communication connection, in particular the control communication.
- the control communication and/or the remote control function can be interrupted automatically, in particular without the intervention of a user.
- the repeated, in particular periodic, receiving or sending of messages can be prevented.
- the request for repeated transmission of an impaired message can be prevented. It can thus be caused that the (possibly exponentially increasing) message traffic of the control communication is interrupted.
- a message can be issued to the user via a user interface to the effect that the vehicle function has been interrupted.
- a (mobile and/or electronic) user device e.g. a smartphone or generally a smart device for a user of a (motor) vehicle.
- the user device can contain a digital key for an access and/or control system of the (motor) vehicle.
- Vehicle wherein the digital key is stored, for example, in a secure memory of the user device.
- the user device can be designed to control one or more vehicle functions, in particular a remote control function, of the vehicle using the digital key.
- the user device comprises the device described in this document (which is designed, for example, as a software application).
- a (road) motor vehicle (in particular a passenger car or a truck or a bus or a motorcycle) which comprises the device described in this document.
- the vehicle can further comprise an access and/or control system which enables a user to control one or more vehicle functions (in particular a remote control function which comprises, for example, automated longitudinal and/or transverse guidance of the vehicle) of the motor vehicle using a (mobile electronic) device with a digital key.
- a method for providing a remote control function (in particular a remote parking function) of a (motor) vehicle is described.
- the remote control function can be controlled via a communication connection between the vehicle and a (user) device (through the repeated, in particular periodic, exchange of messages).
- SW software program
- the SW program can be configured to be executed on a processor and thereby to carry out the method described in this document.
- the storage medium can comprise a software program which is designed to be executed on a processor and thereby to carry out the method described in this document.
- Figure 1a shows an exemplary digital access and/or control system of a vehicle
- Figure 2 shows an exemplary communication between a vehicle and a device for controlling a vehicle function
- Figure 3 is a flowchart of an exemplary method for providing a remote control function of a vehicle.
- a (control) device 101 of the vehicle 100 can be designed to control at least one vehicle function 103, in particular a remote control function, of the vehicle 100 depending on the communication between the device 110 and the vehicle 100, as shown by way of example in Fig. 1b.
- the digital key 115 of the device 110 can be verified, in particular authenticated.
- one or more vehicle functions 103 can be controlled, in particular depending on
- a BLE communication connection 112 may be established between the device 110 and the vehicle 100 as soon as the distance between the device 110 and the vehicle 100 is equal to or less than a first distance threshold 121. This allows the user to remotely control one or more vehicle functions 103 using the device 110.
- the vehicle 100 repeatedly indicates the availability of a BLE communication connection 112, e.g. at a certain frequency.
- Threshold 121 the device 110 (which may also be referred to as a user equipment (UE)) receives the indication message from the vehicle 100 and the BLE communication connection 112 may then be established between the device 110 and the vehicle 100.
- the first distance threshold 121 may depend on the communication capabilities of the device 110, the environment of the vehicle 100 and/or the device 110, and/or the position of the device 110 relative to the vehicle 100.
- the digital key device 110 can thus be used to remotely control a vehicle function 103.
- vehicle function 103 can be referred to as a remote control function.
- An example of a remote control function 103 is an automated parking maneuver in which the vehicle 100 automatically parks in or out of a parking space.
- the vehicle 100 can comprise one or more environmental sensors 104 (e.g. at least one radar sensor, at least one camera, at least one lidar sensor, at least one ultrasonic sensor, etc.), each of which is configured to record environmental data (ie sensor data) relating to the environment of the vehicle 100.
- the (control) device 101 of the vehicle 100 can be configured to have one or more longitudinal and/or To operate lateral guidance actuators 105 (e.g. a drive motor, a steering device and/or a braking device) of the vehicle 100 depending on the environmental data in order to effect the automated parking maneuver.
- lateral guidance actuators 105 e.g. a drive motor, a steering device and/or a braking device
- the user of the vehicle 100 can be located outside the vehicle 100 during the automated parking maneuver.
- the device 110 can be used during the automated parking maneuver to monitor the automated parking maneuver.
- Request messages 201 can be sent periodically at a certain repetition rate (e.g. every 100 ms) from the vehicle 100 to the device 110, and corresponding response messages 202 are sent from the device 110 to the vehicle 100.
- the vehicle 100 in particular the device 101 of the vehicle 100, can check on the basis of the received response messages 202 whether the communication connection 112 between the vehicle 100 and the device 110 is reliable or impaired.
- request messages 201 can be sent repeatedly, in particular periodically, from the device 110 to the vehicle 100. Furthermore, corresponding response messages 202 can be sent from the vehicle 100 to the device 110. This enables the device 110, in particular the (control) device 111 of the device 110, to check whether the communication connection 112 between the vehicle 100 and the device 110 is reliable or impaired.
- the remote control function 103 can be terminated. For example, it can be caused that the automated parking maneuver of the vehicle 100 is terminated and that the vehicle 100 is brought to a standstill. In this way, a safe execution of a remote control function 103 can be achieved.
- the receipt of an impaired request message 201 or response message 202 by a first communication partner can lead to the first communication partner requesting a repeated transmission (in English a “retransmission”) of the impaired message 201, 202 from the second communication partner (i.e. the device 110 or the vehicle 100).
- the repeated transmission can be requested, for example, with a certain retransmission rate (about 30 ms). Requesting a repeated transmission leads to a further increase in the data traffic in the frequency band of the communication connection 112, which can further increase the impairment of the communication connection 112.
- This request message 201 may also be impaired due to the impaired communication connection 112, which in turn may lead to one or more requests for a repeated transmission of this request message 201.
- An initial (relatively slight) impairment of the communication connection 112 can thus lead to an exponentially increasing number of requests for the repeated transmission of request or response messages 201, 202, whereby the data buffers of the communication partners are increasingly filled, which leads to an exponentially increasing delay between request message 201 and corresponding response message 202 and which can ultimately lead to a termination of the remote control function 103 of the vehicle 100.
- the remote control function 103 can be interrupted (by one of the communication partners).
- the vehicle 100 can in particular be brought into a safe state (e.g., to a standstill).
- the sending of request and/or response messages 201, 202 can be suspended (at least temporarily).
- the user of the device 110 may be informed (eg via a user interface of the device 110) that the remote control function has been interrupted.
- the user may also be informed that the remote control function will be resumed (after checking one or more continuation conditions) (without the user having to perform any action).
- After interrupting the remote control function 103 it can be checked (by one of the communication partners) whether one or more continuation conditions for the continuation of the remote control function 103 are fulfilled.
- Example continuation conditions are,
- the comfort, reliability and robustness of a remote control function 103 of a vehicle 100 can be increased in an efficient manner.
- the remote control function 103 in particular the remote parking function 103, can use a pass-through channel of a digital CCC key 115, wherein the channel uses a BLE connection 112 for communication between the vehicle 100 and a device 110 for controlling the remote parking function 103.
- a continuous data transmission from Request and/or response messages 201, 202 to ensure communication availability and/or to exchange control data for vehicle control.
- the vehicle 100 can cyclically send status messages 201 to the control unit 110, and the control unit 110 can respond cyclically (with corresponding messages 202), wherein the messages 202 can include sensor data and/or control data for the vehicle control.
- data transmission via the BLE communication connection 112 may require multiple retransmissions (at a certain retransmission rate).
- the combination of BLE message transmission and relatively high-frequency retransmissions may result in a completely full message queue on one or both sides of the BLE connection 112 (i.e., on one or both communication partners).
- the resulting time delay grows exponentially, so that the remote control function 103 is permanently unavailable for a relatively long period of time and possibly in the event of permanent disruptions (e.g. WLAN).
- the BLE master e.g. the vehicle 100
- the BLE slave e.g. the device 110
- the BLE master e.g. the vehicle 100
- the BLE slave e.g. the device 110
- Healing the communication may be achieved by stopping the communication for a defined interruption period instead of continuing to send request and/or response messages 201, 202 (which may result in an exponential increase the delay).
- the remote control function 103 can thus be interrupted for a defined interruption period.
- the device 110 If, for example, a relatively high communication delay is detected on the device 110 (e.g. by measuring the round trip time of the BLE messages 201, 202), the device 110 that has detected the delay can prevent the sending of cyclic messages 201, 202 for the defined interruption period (e.g. 2 seconds). Within the interruption period, the message queue can be processed and/or cleared. After the interruption period has expired, the device 110 can resume sending cyclic messages 201, 202 (in order to continue the remote control function 103).
- the defined interruption period e.g. 2 seconds
- Fig. 3 shows a flow chart of an exemplary (possibly computer-implemented) method 300 for providing a remote control function 103 of a vehicle 100, wherein the remote control function 103 is controlled via a communication connection 112 between the vehicle 100 and a (mobile and/or electronic) device 110 for controlling the remote control function 103.
- the device 110 can be arranged outside the vehicle 100 (e.g. at a distance of between 1 and 15 meters).
- the communication connection can comprise, in particular, a BLE connection.
- the remote control function can comprise automated longitudinal and/or transverse guidance of the vehicle 100 (e.g. for carrying out an automated parking maneuver). It may be necessary for at least one control element to be actuated on the device (possibly permanently) in order to effect the execution of the remote control function 100 of the vehicle 100.
- the method 300 includes determining 301 that there is an impairment of the communication connection 112, in particular the control communication for controlling the remote control function 103 (e.g. because a data buffer for the control communication between the vehicle 100 and the device 110 has a has reached or exceeded a certain fill level threshold and/or because the time delay of a data message 201, 202 has reached or exceeded a certain delay threshold).
- the method 300 comprises causing 302 that the remote control function 103 and the control communication between the device 110 and the vehicle 100 for controlling the remote control function 103 are interrupted (temporarily and/or automatically).
- the interruption can be designed to bring about a healing of the impaired communication link 112.
- the method 300 further includes recognizing 303 that one or more continuation conditions for a continuation of the remote control function (103) are met. In this case, it can be checked automatically (without user intervention) whether the one or more continuation conditions (such as the expiration of a certain interruption period) are met. The check can be carried out repeatedly if necessary, in particular periodically.
- the method 300 includes, in response to the detection 303, (automatically) causing 304 the remote control function 103 and the control communication between the device 110 and the vehicle 100 to control the remote control function 103 to continue.
