[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] Embodiment 1: The present application discloses a vehicle starting method, which is applied to the field of vehicle configuration. By detecting Bluetooth connection status, mobile device positioning, vehicle HUT interaction and other technologies, the vehicle starting is made more convenient and the user comfort is improved on the basis of ensuring vehicle safety.

[0042] For details, please refer to Figure 1 A vehicle starting method disclosed in this embodiment includes the following steps:

[0043] Step 101: PEPS disconnects the Bluetooth connection between the mobile device and the vehicle and starts timing. When a first preset time is reached, if the mobile device and the vehicle are still in a Bluetooth disconnected state, the process proceeds to step 102.

[0044] The full name of the PEPS is Passive Entry Passive Start System.

[0045] In a possible implementation, as a prerequisite for executing step 101, PEPS may unlock the door of the vehicle according to the received door unlocking signal, and start the above step 101 when it is detected that the door is opened.

[0046] The PEPS may be based on a received unlock door signal from an APP of the mobile device.

[0047] When the user steps on the brake in this step, PEPS will prompt the user to step on the brake again later through the terminal information display unit HUT. Wherein, when the HUT prompts, it can display text prompts on the multimedia screen on the vehicle or through the voice system.

[0048] Step 102: PEPS determines whether the mobile device is within a preset range of the vehicle. If yes, the process proceeds to step 103; if not, the vehicle is locked.

[0049] The PEPS locates the position of the mobile device and the vehicle through the GPS positioning system and calculates the distance between the two. The preset range should be near the vehicle to ensure that the mobile device is on the user using the vehicle and to ensure the safety of the vehicle. When setting the preset range of the vehicle, a circular area can be determined by setting a radius with the vehicle as the center, or a rectangular area with a length and width set or an area determined in other ways, which can facilitate the PEPS to determine whether the mobile device is on the user using the vehicle.

[0050] Step 103: PEPS prompts the user to enter a password through the vehicle's head unit (HUT). The HUT can display text prompts through the vehicle's multimedia screen or through a voice system.

[0051] The HUT is an information presentation unit integrating voice, text, animation and graphics, and is used to implement information input and output on a vehicle multimedia screen, a voice system, or a camera device.

[0052] When the user enters the password, he needs to touch the vehicle multimedia screen and enter it manually. The password can be a string password containing numbers, English, and symbols, or a voice password, fingerprint password, or gesture password. If the vehicle is equipped with a camera, the password input process can also be face recognition.

[0053] Step 104: PEPS determines whether the password is correct. If so, the vehicle is started; if not, the vehicle is locked.

[0054] In a possible implementation, the HUT receives the password input by the user through the vehicle multimedia screen, encrypts it using the AES-128 encryption algorithm, and sends the encrypted ciphertext to the PEPS. The PEPS decrypts the data according to the key agreed with the HUT and compares the decrypted password with the stored password.

[0055] The stored password may be preset by the system or set by the user through a mobile device APP, and it is recommended that the stored password be changed regularly to ensure vehicle safety.

[0056] When comparing passwords, a preset number of passwords are allowed to be entered. If the number of incorrect passwords exceeds the preset number, the vehicle will be locked. The preset number of passwords can be one or three times, as long as the vehicle safety is guaranteed.

[0057] After the password comparison is passed, the HUT prompts the user to step on the brake to use the vehicle normally and counts the time, which is the second preset time.

[0058] If the brake is not detected within the second preset time, the PEPS determines the Bluetooth connection status between the mobile device and the vehicle and the location of the mobile device.

[0059] If the mobile device is not connected to the vehicle via Bluetooth or is not within a preset range of the vehicle, the vehicle is locked.

[0060] After the vehicle is started normally, PEPS sends a prompt message to the mobile device through T-BOX that the vehicle has been started. The prompt message can be sent via SMS or APP.

[0061] The method described in this embodiment allows the vehicle to be started by entering a password in the vehicle in case of unstable Bluetooth connection. This avoids the problem of repeated password authentication of mobile devices inside and outside the vehicle and long waiting time for Bluetooth connection, making emergency starting of the vehicle in a keyless state more convenient and comfortable, and improving user comfort.

[0062] Embodiment 2: This application discloses another method for starting a vehicle, please refer to Figure 2 Compared with the first embodiment, the method described in this embodiment is aimed at the situation where there is no Bluetooth connection between the mobile device and the vehicle, and the vehicle is started only by a password.

[0063] Step 201: Within a first preset time, the mobile device does not establish a Bluetooth connection with the vehicle.

[0064] When the user presses the brakes in this step, PEPS will use text on the vehicle multimedia screen through the HUT to remind the user to press the brakes again later.

[0065] Step 202: PEPS determines whether the mobile device is within a preset range of the vehicle through the GPS positioning system. If yes, the process proceeds to step 203; if not, the vehicle is turned off.

[0066] The preset range of the vehicle should be near the vehicle to ensure that the mobile device is on the user who is using the vehicle.

[0067] Step 203: PEPS prompts the user to enter a password on the vehicle multimedia screen using text via the HUT.

[0068] Step 204: PEPS determines whether the password is correct.

[0069] The HUT receives the password input by the user, encrypts it into ciphertext using the AES-128 encryption algorithm, and sends it to the PEPS. The PEPS decrypts the data into the password according to the key agreed with the HUT, and compares it with the stored password. If it is correct, it goes to step 205; if not, the vehicle is locked.

[0070] When comparing passwords, a preset number of passwords are allowed to be entered, and the vehicle is locked if the number of incorrect passwords exceeds the preset number. The preset number of passwords can be one or three times, as long as the vehicle safety is guaranteed.

[0071] Step 205: The HUT uses text to prompt the user on the vehicle multimedia screen that the password verification is passed, and the vehicle can be started by stepping on the brake, and a timer is counted, and the timer time is a second preset time.

[0072] Step 206: Detect whether the brake is pressed within the second preset time, if yes, start the vehicle; if no, PEPS determines the location of the mobile device.

[0073] Locks the vehicle if the location is not within a preset range of the vehicle.

[0074] The method described in this embodiment starts the vehicle by a password when there is no Bluetooth connection, avoiding troubles to users caused by unstable Bluetooth connection and long connection time. The user can enter the password to start the vehicle in the car, which is convenient and efficient and improves user comfort.

[0075] Example 3: This application discloses a method for starting a vehicle in a scenario, please refer to Figure 3 The method described in this embodiment aims at the scenario where the Bluetooth connection fails, guides the user to enter the password in the vehicle multimedia to start the vehicle, and allows the user to enter the password incorrectly once.

[0076] Step 301: The user clicks on the APP to unlock on the mobile device, and the PEPS unlocks the car door after receiving the signal and starts timing, which is a first preset time of one minute.

[0077] Step 302: Determine whether the mobile device has established a Bluetooth connection with the vehicle within one minute.

[0078] If the user steps on the brake at this time, the HUT will prompt the user through voice to step on the brake again later.

[0079] Step 303: If the Bluetooth connection is not established after one minute, PEPS determines whether the mobile device is within the preset range through the GPS positioning system. If yes, the process proceeds to step 304; if not, the vehicle is locked.

[0080] The preset range is a circular area with a radius of three meters with the vehicle as the center.

[0081] Step 304: The HUT prompts the user to enter a password on the vehicle multimedia screen through voice.

[0082] Step 305: PEPS determines whether the password is correct.

[0083] HUT receives the password input by the user, encrypts it into ciphertext using the AES-128 encryption algorithm, and sends it to PEPS. PEPS decrypts the data into a password according to the key agreed with HUT, and compares it with the stored password. If yes, it goes to step 306; if not, it goes to step 308.

[0084] Step 306: The HUT prompts the user through voice that the password verification is successful, and the vehicle can be started by stepping on the brake, and the timing is eight seconds. The timing time is eight seconds, which is the second preset time.

[0085] Step 307: Determine whether the brake is pressed within eight seconds. If yes, start the vehicle; if not, proceed to step 310.

[0086] Step 308: The HUT prompts the user to input the password again through voice.

[0087] Step 309: PEPS determines whether the password is correct.

[0088] The HUT receives the password input by the user, encrypts it into ciphertext using the AES-128 encryption algorithm, and sends it to the PEPS. The PEPS decrypts the data into the password according to the key agreed with the HUT, and compares it with the stored password. If yes, it goes to step 306; if not, the vehicle is locked.

[0089] Step 310: Determine the Bluetooth connection status between the mobile device and the vehicle and the location of the mobile device. If the Bluetooth is not connected or the mobile device is not within the preset range, lock the vehicle.

[0090] In the method described in this embodiment, the first preset time is set to one minute, the second preset time is set to eight seconds, and the preset range is a circular area with a radius of three meters with the vehicle as the center. In the case of Bluetooth connection difficulty, the method described in this embodiment allows the vehicle to be started by entering a password on the multimedia screen, and the vehicle guides the user to operate through voice prompts, thereby realizing convenient and quick start of the vehicle.
