[0045] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0046] At present, the control signal transmitter in the off-vehicle control technology is mainly the vehicle's own car lock remote control or car control application software. The car lock remote control transmits infrared signals, and the receiver in the vehicle receives the control signal and performs the corresponding operation. The information capacity of the infrared signal is small, and the fixed button can usually only send a single on-off signal. Due to the high frequency and short wavelength of infrared rays, the use distance of the remote control is greatly limited. The long control distance is prone to signal loss, affecting the control safety of the vehicle. The control application software uses the mobile network and Bluetooth communication to control the vehicle, and the real-time transmission of the vehicle control signal cannot be guaranteed. When the mobile network is used as the information transmission medium, there are situations such as poor signal in the underground garage, network delay, data packet loss, etc. At the same time, when using mobile traffic data, the vehicle must also be connected to the Internet, which has high requirements on the hardware of the user and the vehicle. When the Bluetooth module is used to connect the vehicle, there is a problem of unstable Bluetooth signal, which is prone to disconnection and interference.

[0047] The main technical solution of the present invention is: receiving a communication connection request sent by a control device and establishing a communication connection with the control device; based on the communication connection, receiving a vehicle control signal sent by the control device; verifying whether the vehicle control signal is valid; if the vehicle control signal is valid, parsing the vehicle control signal to control the controlled vehicle to change the vehicle operating state.

[0070] In one embodiment, the processor 1001 calls the vehicle remote control program stored in the memory 1005 and may also perform the following steps:

[0072] According to the second control request, the controlled vehicle is controlled to perform multimedia playback settings, air conditioning temperature settings, window lifting settings, trunk switch settings or door unlocking settings.

[0074] Dynamically acquiring the real-time vehicle operation status of the controlled vehicle, and acquiring the vehicle operation data of the controlled vehicle according to the real-time vehicle operation status;

[0075] The vehicle operation data is sent to a control device, wherein the vehicle operation data includes at least one of a vehicle-mounted camera image, an operating speed, an engine speed, a gear information, a water temperature, an air-conditioning temperature, and an air volume.

[0076] The embodiment of the present invention provides a vehicle remote control method, referring to Figure 2 , Figure 2 The figure is a flow chart of a first embodiment of a vehicle remote control method according to the present invention.

[0077] In this embodiment, the vehicle remote control method includes:

[0078] Step S10, receiving a communication connection request sent by a control device, and establishing a communication connection with the control device;

[0079] In the off-vehicle vehicle control scenario, the vehicle control process can be divided into the stages of control signal sending, control signal transmission and control signal reception. Generally, the control signal receiving end is the controlled vehicle. In this embodiment, the control signal sending end is the control device. The control device can be a mobile terminal for sending vehicle control signals, such as a mobile phone, a tablet, a mobile computer, etc., or a portable device for sending vehicle control signals, such as a programmable controller, a remote control, etc. The control device can be connected to the local area network by 2.4G or 5G WiFi (wireless network communication technology). The vehicle control user interface in the control device can be a vehicle control software, control page or applet installed in the operating system of smart mobile devices such as Android and IOS.

[0080] In the control signal transmission stage, this embodiment uses a local area network as a signal transmission medium. The local area network has the advantage of large bandwidth. When controlling the vehicle, it can transmit non-switch variables such as vehicle speed and steering angle, making the vehicle control function more powerful. A built-in server can be installed in the vehicle, and the built-in server is used as a control signal forwarding service module to form a local area network between the control device and the controlled vehicle. Furthermore, the built-in server can be installed in the vehicle domain controller, and the control signal receiving module in the vehicle can also be installed in the domain controller. When the vehicle is started, the built-in server and the control signal receiving module in the domain controller are also started and run, and the vehicle local area network is completed. The vehicle can be started by starting the vehicle ignition switch or by the vehicle remote control button.

[0081] Figure 3 This is a possible schematic diagram of a local area network vehicle control in this embodiment, such as Figure 3 As shown in the figure, when the user needs to control the vehicle, the control device can be connected to the vehicle LAN first, the vehicle LAN address can be searched in the vehicle LAN, and a communication connection request can be sent to the vehicle to connect the control device to the built-in server. The built-in server receives the communication connection request, responds to the communication connection request, and establishes a LAN communication connection between the vehicle and the control device. The control device is connected to the vehicle LAN Internet, which can ensure that there is only one controlled vehicle in the same network segment, thereby improving the accuracy and safety of vehicle control.

[0082] Step S20, receiving a vehicle control signal sent by the control device based on the communication connection;

[0083] After the signal receiving module in the vehicle receives the message that the control device is connected to the built-in server, it can confirm the network connection status. After the handshake is successful, it can be regarded as the data connection between the mobile control program in the control device and the vehicle is successful.

[0084] The user controls the vehicle in the control interface of the control device, and the control device can convert the user's control command into a control signal and transmit it to the vehicle. The vehicle can receive the control signal through the control signal receiving module in the domain controller. When the control signal is transmitted to the vehicle through the local area network, the MQTT (Message Queuing Telemetry Transport) protocol can be used to serialize and package the control signal for transmission. MQTT is a publish / subscribe messaging protocol designed for remote devices with low hardware performance and poor network conditions. Using the MQTT Internet of Things protocol as the data transmission protocol can achieve advantages such as low data bandwidth occupancy.

[0085] Step S30, verifying whether the vehicle control signal is valid;

[0086] After receiving the vehicle control signal, the domain controller first verifies the validity of the vehicle control signal. In one practicable manner, the vehicle control signal may include verification data for validity verification, and the domain controller may first extract the verification data from the vehicle control signal. If the verification data is successfully verified, the vehicle control signal is valid; if the verification data fails to be verified, the vehicle control signal is invalid.

[0087] Step S40: If the vehicle control signal is valid, the vehicle control signal is analyzed to control the controlled vehicle to change the vehicle operating state.

[0088] After the domain controller verifies that the vehicle control signal is valid, it can control the vehicle according to the vehicle control signal. Based on the local area network and MQTT protocol, the control signal can reach a control frequency of at least 20Hz, which can achieve lower latency.

[0089] As an example, if the vehicle control signal is valid, the step of parsing the vehicle control signal to control the controlled vehicle to change the vehicle operating state may include:

[0090] Step A1: If the vehicle control signal is valid, convert the vehicle control signal into a first control request. After verifying that the vehicle control signal is valid, the domain controller may convert the vehicle control signal into a binary value to generate a first control request. If the vehicle control signal is invalid, the control instruction in the vehicle control signal is not executed, and the vehicle domain controller may feedback information that the vehicle control signal is invalid to the control device.

[0091] Step A2, according to the first control request, control the controlled vehicle to perform power drive and / or steering drive. The domain controller can send the first control request to the power control unit and / or the steering control unit through the CAN (Controller Area Network) bus in the vehicle body. After receiving the first control request, the power control unit and / or the steering control unit realizes the control of the vehicle power drive device and / or the steering drive device through internal closed-loop calculation to realize the forward, reverse or steering operation of the vehicle.

[0092] In this embodiment, a communication connection request sent by a control device is received, a communication connection with the control device is established, a vehicle control signal sent by the control device is received, and after verifying that the vehicle control signal is valid, the vehicle control signal is parsed to control the controlled vehicle to change the vehicle operating state. The control device can transmit control data via a local area network connection with the controlled vehicle to achieve control of non-switching variables such as vehicle speed and steering angle, and verify the validity of the vehicle control signal, thereby avoiding misoperation caused by loss of vehicle control signal data and improving the stability of remotely controlled vehicles.

[0093] Further, in a second embodiment of the vehicle remote control method of the present invention, referring to Figure 4 , the method comprising:

[0094] Step S11, detecting whether a communication connection is established with the control device for the first time;

[0095] After the control device is connected to the built-in server, the built-in server can obtain the device information of the control device, such as the device identification number, device name, etc., and save the device information. If the built-in server detects that the device information of the control device connected this time has not been saved, it can be regarded as the first time to establish a communication connection with the control device; if the built-in server detects the saved device information, it can be regarded as not the first time to establish a communication connection with the control device.

[0096] Step S12: If yes, confirm the encryption method and standard handshake sequence with the control device;

[0097] If it is the first time to establish a communication connection with the control device, the encryption method and standard handshake sequence for vehicle control signal transmission can be confirmed with the control device. The encryption method can be an encryption logic algorithm formula or a password matching set. After confirmation, the encryption method can be used to encrypt and verify the validity of the vehicle control signal.

[0098] Step S13, decrypting the vehicle control signal according to the encryption method to obtain a handshake sequence to be verified;

[0099] The vehicle control signal may consist of an encryption verification part, a control variable part, and an integrity verification part. In one practicable manner, the control device may encrypt the standard handshake sequence determined when the controlled vehicle is first paired according to the encryption logic algorithm, and write the unordered string obtained by the encryption calculation into the encryption verification part of the vehicle control signal. The control variable part may store the user's actual control quantity information of the vehicle control, such as the vehicle speed information when the vehicle is powered or the steering angle information when the vehicle is steering driven. The integrity verification part includes a value calculated by a preset verification formula. The verification formula may be determined when the control device is first paired with the vehicle.

[0100] After receiving the vehicle control signal, the domain controller may first use a determined encryption method to decrypt the vehicle control signal to obtain a handshake sequence to be verified.

[0101] Step S14, if the handshake sequence to be verified is the same as the standard handshake sequence, a control variable part in the vehicle control signal is calculated using a preset verification formula to obtain a control value;

[0102] If the handshake sequence to be verified is the same as the standard handshake sequence, it means that the vehicle control signal is legal and the integrity check can be continued. When performing the integrity check, the control signal part of the vehicle control signal can be calculated using a preset check formula to obtain the control value. The preset check formula can be determined when the control device is paired with the vehicle for the first time.

[0103] If the handshake sequence to be verified is different from the standard handshake sequence, it means that the vehicle control signal is illegal and the control request corresponding to the vehicle control signal is not executed.

[0104] Step S15, if the control value is the same as the integrity value in the vehicle control signal, determining that the vehicle control signal is valid;

[0105] If the control value calculated by the domain controller is the same as the integrity value in the vehicle control signal, it can be determined that the vehicle control signal is valid, the validity verification is completed, and the domain controller can control the vehicle according to the vehicle control signal.

[0106] If the control value is different from the integrity value, the vehicle control signal is invalid and the domain controller does not execute the control request corresponding to the vehicle control signal.

[0107] During the transmission of vehicle control signals, data loss may occur. In this case, if the vehicle control signal is determined to be invalid, the controlled vehicle will not experience erroneous operation due to data loss, thereby improving the stability and safety of vehicle control.

[0108] Step S16, generating a confirmation signal according to the vehicle control signal;

[0109] The confirmation signal may also include an encryption check part, a control variable part, and an integrity check part. After verifying that the vehicle control signal is valid, the control variable part of the confirmation signal may be generated based on the actual control amount information in the vehicle control signal, or the device confirmation information may be used as the control variable part of the confirmation signal.

[0110] Step S17: sending the confirmation signal to the control device.

[0111] The domain controller can send a confirmation signal to the control device through the vehicle local area network. After the control device receives the confirmation signal, it can be regarded as a complete control cycle. In a single control cycle, the signal transmission between the control device and the controlled vehicle can be regarded as a two-way transmission and reception mode.

[0112] In the two-way transmission and reception mode, the control device can confirm whether the vehicle control signal sent by itself has been executed to ensure that the vehicle control operation is effective within each complete control cycle.

[0113] In this embodiment, the signal transmitted between the control device and the controlled vehicle is encrypted, and the validity is verified by a determined encryption method and handshake sequence. A two-way transceiver mode is used to determine the complete control cycle, thereby improving the security of vehicle control signal transmission.

[0114] Further, in the third embodiment of the vehicle remote control method of the present invention, referring to Figure 5 , the method comprising:

[0115] Step S21, if the vehicle control signal is valid, converting the vehicle control signal into a second control request;

[0116] After verifying that the vehicle control signal is valid, the domain controller may convert the vehicle control signal into a binary value and generate a second control request. If the vehicle control signal is invalid, the control instruction in the vehicle control signal is not executed, and the vehicle domain controller may feedback information that the vehicle control signal is invalid to the control device.

[0117] Step S22, according to the second control request, controlling the controlled vehicle to perform multimedia playback settings, air conditioning temperature settings, window lifting settings, trunk switch settings, or door unlocking settings;

[0118] The domain controller can send the second control request to the audio and video entertainment control unit, temperature control unit, window control unit, trunk control unit or door control unit in the vehicle through the CAN bus. The audio and video entertainment control unit controls the playback and pause of music, the temperature control unit controls the air conditioning switch and air conditioning temperature adjustment, the window control unit controls the lifting and lowering of the windows, the trunk control unit controls the opening and closing of the trunk, and the door control unit controls the locking and unlocking of the doors.

[0119] Step S23, dynamically acquiring the real-time vehicle operation status of the controlled vehicle, and acquiring the vehicle operation data of the controlled vehicle according to the real-time vehicle operation status;

[0120] The vehicle operation data is generated by various components in the controlled vehicle. In a possible implementation, the real-time vehicle operation data can be dynamically acquired through an OBD (On Board Diagnostics) interface in the vehicle.

[0121] Step S24, sending the vehicle operation data to the control device, wherein the vehicle operation data includes at least one of the vehicle camera image, operating speed, engine speed, gear information, water temperature, air conditioning temperature, and air volume.

[0122] Based on the large bandwidth and low latency characteristics of the local area network and MQTT, information such as the vehicle camera image, operating speed, engine speed, gear information, water temperature, air conditioning temperature, and air volume can be sent to the control device without affecting the user's ability to send control signals to the controlled vehicle, thereby controlling the controlled vehicle to execute control requests.

[0123] In this embodiment, the user can control the controlled vehicle to perform multiple settings through the second control request, and can also view the vehicle operation data on the control device. The second control request can be executed in parallel with the first control request, which expands the traditional off-vehicle control function and improves the operational efficiency of off-vehicle control.

[0124] The embodiment of the present invention also provides a vehicle remote control device, such as Figure 6 As shown, the vehicle remote control device includes:
