[0025] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0026] The present application embodiment provides a control method for a vehicle-mounted battery vehicle, please refer to Figure 1, which shows a schematic diagram of the implementation environment of the method provided in the embodiment of the present application. The implementation environment may include: VCU11, vehicle-mounted inflation mechanism 12, vehicle-mounted charging mechanism 13, vehicle's central console large screen 14, mobile phone screen 15, vehicle's communication system 16, vehicle's communication interface 17, battery vehicle's communication interface 18, battery vehicle control system 19, battery vehicle's tire pressure management system 20, battery vehicle power supply mechanism 21, battery vehicle's power supply interface 22, vehicle's power supply interface 23 and battery vehicle's display screen 24. The vehicle-mounted battery vehicle in this application refers to a battery vehicle when it is mounted on a vehicle. The battery vehicle can be mounted on a vehicle or can be ridden away from the vehicle.

[0027] Optionally, when the vehicle's communication interface 17 is connected to the battery vehicle's communication interface 18, and the vehicle's power supply interface 23 is connected to the battery vehicle's power supply interface 22, the battery vehicle control system 19 obtains the second remaining power of the battery vehicle through the battery vehicle's power supply mechanism 21; in response to the second remaining power being less than the third power threshold, the battery vehicle control system generates a charging request, and sends it together with the battery vehicle's power as a battery vehicle power detection result to the vehicle's communication interface 17, and then sends it to VCU11 through the vehicle's communication system 16. VCU11 sends a first prompt message on whether charging is allowed through the large screen 14 of the vehicle's center console and the screen 15 of the mobile phone. Similarly, VCU11 also displays the second remaining power through the large screen 14 of the vehicle's center console and the screen 15 of the mobile phone. Optionally, the display screen 24 of the battery vehicle can also display the second remaining power.

[0028] Exemplarily, if VCU11 receives information that a control that allows charging of the battery vehicle is clicked from at least one of the large screen 14 of the vehicle center console or the screen 15 of the mobile phone, the detection result of the first confirmation charging information indicates that the battery vehicle is allowed to be charged. VCU11 obtains the first remaining power of the vehicle's power battery through the vehicle's onboard charging mechanism 13. VCU11 displays the first remaining power through the large screen 14 of the vehicle center console and the screen 15 of the mobile phone. In response to the first remaining power being greater than the first power threshold, VCU11 controls the vehicle's onboard charging mechanism 13 to transmit electric energy to the battery vehicle's power supply interface 22 through the vehicle's power supply interface 23, and charges the battery in the battery vehicle's power supply mechanism 21 through the battery vehicle's power supply interface 22. After starting to charge the battery vehicle, VCU11 receives the detection result of charging completion, and in response to the detection result of charging completion indicating that the power of the battery vehicle has reached the second power threshold, VCU11 controls the vehicle's onboard charging mechanism 13 to stop charging the battery vehicle.

[0029] Optionally, when the vehicle's communication interface 17 is connected to the battery vehicle's communication interface 18, the battery vehicle control system 19 obtains the battery vehicle's tire pressure through the battery vehicle's tire pressure management system 20; in response to the tire pressure being less than the first tire pressure threshold, the battery vehicle's tire pressure detection result includes an inflation request. The battery vehicle control system 19 sends the battery vehicle's tire pressure detection result and tire pressure to the vehicle's communication interface 17 through the battery vehicle's communication interface 18, and then sends them to VCU11 through the vehicle's communication system 16. VCU11 displays the third prompt message of whether inflation is allowed through the large screen 14 of the vehicle's center console and the screen 15 of the mobile phone. Similarly, VCU11 also displays the tire pressure through the large screen 14 of the vehicle's center console and the screen 15 of the mobile phone. Optionally, the battery vehicle's display screen 24 can also display the tire pressure.

[0030] In a possible implementation, if VCU11 receives information that a control that allows the battery vehicle to be inflated is clicked from at least one of the large screen 14 of the vehicle center console or the screen 15 of the mobile phone, the detection result of the confirmation inflation information indicates that the battery vehicle is allowed to be inflated. In response to the confirmation that the detection result of the inflation information indicates that the battery vehicle is allowed to be inflated, VCU11 inflates the tire pressure management system 20 of the battery vehicle through the vehicle-mounted inflation mechanism 12. After starting to inflate the battery vehicle, VCU11 receives a detection result of inflation completion; in response to the detection result of inflation completion indicating that the tire pressure of the battery vehicle has reached the second preset tire pressure threshold, VCU11 controls the vehicle-mounted inflation mechanism 12 to stop inflating the battery vehicle.

[0031] Among them, VCU11, the vehicle-mounted inflation mechanism 12, the vehicle-mounted charging mechanism 13, the vehicle's central console large screen 14, the mobile phone's screen 15, the vehicle's communication system 16, the vehicle's communication interface 17, the battery vehicle's communication interface 18, the battery vehicle's control system 19, the battery vehicle's tire pressure management system 20, the battery vehicle's power supply mechanism 21, the battery vehicle's power supply interface 22, the vehicle's power supply interface 23 and the battery vehicle's display screen 24 establish communication connections through wired or wireless networks.

[0032] Based on the above Figure 1 In the implementation environment shown in FIG. 1 , the present application embodiment provides a control method for a vehicle-mounted battery vehicle. Figure 2 As shown, the battery vehicle is mounted on the battery vehicle mounting structure of the vehicle. Taking the method applied to the VCU as an example, the method includes steps 201 to 205.

[0033] In step 201, when the communication interface of the vehicle is connected to the communication interface of the battery vehicle, and the power supply interface of the vehicle is connected to the power supply interface of the battery vehicle, the VCU receives a battery vehicle power detection result of the battery vehicle.

[0034] For example, a battery vehicle carrying structure is provided on the vehicle for placing the battery vehicle, wherein the battery vehicle carrying structure includes a guide structure and a locking structure, and the guide structure can ensure that the communication interface of the vehicle is connected to the communication interface of the battery vehicle, and the power supply interface of the vehicle is connected to the power supply interface of the battery vehicle. The locking structure can ensure that the battery vehicle is firmly installed on the vehicle and will not shift under various working conditions.

[0035] In one possible implementation, after the electric vehicle is loaded on the electric vehicle loading structure, when the vehicle's communication interface is connected to the electric vehicle's communication interface, and the vehicle's power supply interface is connected to the electric vehicle's power supply interface, the VCU receives the electric vehicle's battery power detection result, wherein the electric vehicle's battery power detection result includes the second remaining power of the electric vehicle and may also include a charging request.

[0036] Optionally, when the communication interface of the vehicle is connected to the communication interface of the battery vehicle, and the power supply interface of the vehicle is connected to the power supply interface of the battery vehicle, the battery vehicle control system obtains the second remaining power of the battery vehicle through the battery vehicle power supply mechanism; in response to the second remaining power being less than the third power threshold, the battery vehicle power detection result includes a charging request; in response to the second remaining power being greater than or equal to the third power threshold, the battery vehicle control system generates a charging request, which is used together with the power of the battery vehicle as the battery vehicle power detection result. Exemplarily, the third power threshold can be set based on experience as the remaining power of the battery vehicle when it needs to be charged.

[0037] Exemplarily, after determining the battery vehicle power detection result, the battery vehicle control system sends the battery vehicle power detection result and the second remaining power to the vehicle's communication interface through the battery vehicle's communication interface, and then sends them to the VCU through the vehicle's communication system.

[0038] In step 202, in response to the battery vehicle power detection result including a charging request, the VCU issues a first prompt message asking whether charging is allowed.

[0039] Optionally, after receiving the battery vehicle power detection result, the VCU sends a first prompt message of whether charging is allowed in response to the battery vehicle power detection result including a charging request. Optionally, the method of sending the first prompt message includes, but is not limited to: the VCU sends the first prompt message to the large screen of the vehicle center console and the APP of the driver's mobile phone, so as to display the text of whether charging is allowed on the large screen of the vehicle center console and the screen of the mobile phone.

[0040] In a possible implementation, after receiving the second remaining power, the VCU also sends the second remaining power to the large screen of the vehicle center console and the APP of the driver's mobile phone, so as to display the second remaining power on the large screen of the vehicle center console and the screen of the mobile phone. Optionally, the display screen of the battery vehicle can also display the second remaining power.

[0041] In step 203, the VCU receives a first detection result of confirming charging information, where the first detection result of confirming charging information is used to indicate whether charging of the battery vehicle is allowed.

[0042] Optionally, after the VCU sends the first prompt message, the VCU receives a detection result of the first confirmation charging information, wherein the detection result of the first confirmation charging information is used to indicate whether the battery vehicle is allowed to be charged. Exemplarily, the VCU receives the detection result of the first confirmation charging information, including: if the VCU receives information that a control that allows charging of the battery vehicle is clicked on the large screen of the vehicle's center console, or receives at least one of information that a control that allows charging of the battery vehicle is clicked on the screen of the driver's mobile phone, the detection result of the first confirmation charging information indicates that the battery vehicle is allowed to be charged; if the VCU does not receive information that a control that allows charging of the battery vehicle is clicked on the large screen of the vehicle's center console, and does not receive information that a control that allows charging of the battery vehicle is clicked on the screen of the driver's mobile phone, the detection result of the first confirmation charging information indicates that the battery vehicle is not allowed to be charged.

[0043] In step 204, in response to the detection result of the first confirmation charging information indicating that the battery vehicle is allowed to be charged, the VCU obtains a first remaining power of the power battery of the vehicle.

[0044] Exemplarily, after the VCU receives the detection result of the first confirmation charging information, in response to the detection result of the first confirmation charging information indicating that the battery vehicle is allowed to be charged, the VCU obtains the first remaining power of the vehicle's power battery, including: the VCU obtains the first remaining power of the vehicle's power battery from the vehicle's onboard charging mechanism through the bus. After obtaining the first remaining power of the power battery, the VCU sends the first remaining power to the large screen of the vehicle's center console and the APP of the driver's mobile phone, for displaying the first remaining power through the large screen of the vehicle's center console and the screen of the mobile phone. In one possible implementation, the bus may be a CAN (Controller Area Network) bus.

[0045] In step 205, in response to the first remaining power being greater than the first power threshold, the VCU controls the vehicle's onboard charging mechanism to charge the battery vehicle through the power supply interface.

[0046] In a possible implementation, after obtaining the first remaining power, the VCU compares the first remaining power with the first power threshold. In response to the first remaining power being greater than the first power threshold, the VCU transmits a signal of preparing to charge to the communication interface of the battery vehicle through the vehicle's communication system and the vehicle's communication interface, which is then sent to the battery vehicle control system by the battery vehicle's communication interface. After receiving the signal of preparing to charge, the battery vehicle control system transmits the signal of preparing to charge to the battery vehicle power supply mechanism, and the battery vehicle power supply mechanism enters a state of preparing to charge. When the battery vehicle power supply mechanism completes the preparations before charging, it will feedback to the VCU information that it is ready to accept charging.

[0047] Exemplarily, after receiving feedback from the power supply mechanism of the battery vehicle that it is ready to accept charging, the VCU controls the vehicle's on-board charging mechanism to charge the battery vehicle through the power supply interface, including: the VCU controls the vehicle's on-board charging mechanism to transmit electric energy to the power supply interface of the battery vehicle through the vehicle's power supply interface, and charges the battery vehicle's power supply mechanism through the power supply interface of the battery vehicle, wherein the battery vehicle's power supply mechanism includes the battery of the battery vehicle.

[0048] In a possible implementation, in response to the first remaining power being less than or equal to the first power threshold, the VCU issues a prompt message that the power battery power is insufficient for charging the electric vehicle. Optionally, the prompt method includes, but is not limited to: the VCU sends the power battery power shortage information to the large screen of the vehicle center console and the APP of the driver's mobile phone, so as to display the power battery power shortage information on the large screen of the vehicle center console and the screen of the mobile phone; the VCU controls the sound system inside the vehicle to broadcast the power battery power shortage information.

[0049] Exemplarily, the first power threshold can be determined based on the first distance from the current location of the vehicle to the destination of this trip, and the power of the power battery required for the remaining journey is calculated based on the first distance, and the total power of the power battery required for the remaining journey plus the backup power is used as the first power threshold. Optionally, the backup power can be set based on experience, and the first distance and the type of the current section can be read from the vehicle navigation system. Based on the type of the current section and the first distance, the power of the power battery required for the remaining journey is determined based on the power required per kilometer for different types of sections that are predetermined.

[0050] In one possible implementation, after the electric vehicle starts to charge, the VCU receives a charging completion detection result, wherein the charging completion detection result is used to indicate whether the power of the electric vehicle has reached a second power threshold; in response to the charging completion detection result indicating that the power of the electric vehicle has reached the second power threshold, charging of the electric vehicle is stopped.

[0051] Optionally, if the detection result of charging completion indicates that the second remaining power is greater than or equal to the second power threshold, the VCU controls the on-board charging mechanism to stop charging the battery vehicle. Exemplarily, the second power threshold can be set based on experience, and it is necessary to ensure that the second power threshold is greater than the third power threshold.

[0052] Exemplarily, during vehicle driving, the vehicle's cruising range is predicted based on the first remaining power; in response to the cruising range being less than the distance from the vehicle's current position to the nearest charging post, the battery vehicle is controlled to charge the vehicle. In one possible implementation, the VCU continuously monitors the first remaining power of the power battery, and predicts the vehicle's cruising range based on the first remaining power. Optionally, the vehicle's cruising range on the current road section can be predicted based on the type of the current road section and the first remaining power, according to the power required per kilometer for different types of road sections that are predetermined. The nearest charging post in this application can be searched by the vehicle navigation system, and does not necessarily mean that it is the nearest charging post in reality.

[0053] In a possible implementation, after determining the cruising range of the vehicle, the second distance from the current position of the vehicle to the nearest charging pile is obtained through the navigation system, and the cruising range of the vehicle is compared with the second distance. If the cruising range is less than the second distance, the VCU controls the battery car to charge the vehicle. Optionally, during the driving process of the vehicle, if the battery of the vehicle is low on power, the VCU controls the battery car controller to charge the vehicle.

[0054] Exemplarily, the VCU controls the battery vehicle to charge the vehicle, including: the VCU transmits a signal requesting charging to the communication interface of the battery vehicle through the vehicle's communication system and the vehicle's communication interface, and the communication interface of the battery vehicle sends it to the battery vehicle control system. After receiving the signal requesting charging, the battery vehicle control system transmits the signal requesting charging to the battery vehicle power supply mechanism, and the battery vehicle power supply mechanism charges the vehicle power supply mechanism through the battery vehicle power supply interface and the vehicle power supply interface.

[0055] In a possible implementation, when charging the power battery, the VCU continuously monitors the first remaining power of the power battery. If the first remaining power of the power battery reaches the power required to go to the nearest charging pile, the VCU controls the battery vehicle power supply mechanism to stop charging the power battery of the vehicle. Optionally, the power required to go to the nearest charging pile can be calculated based on the type of the current road section and the second distance according to the power required per kilometer under different types of road sections that are predetermined.

[0056] Optionally, the VCU obtains the external charging status of the vehicle, wherein the external charging status of the vehicle includes whether the vehicle is being externally charged and the vehicle is not being externally charged; in response to the charging status of the vehicle being that the vehicle is being externally charged, a second prompt message is issued as to whether the electric battery vehicle is to be charged simultaneously; a detection result of a second confirmation charging message is received, wherein the detection result of the second confirmation charging message is used to indicate whether the electric battery vehicle is allowed to be charged simultaneously; in response to the detection result of the second confirmation charging message indicating that the electric battery vehicle is allowed to be charged simultaneously, the vehicle-mounted charging mechanism of the vehicle is controlled to charge the electric battery vehicle through the power supply interface.

[0057] Exemplarily, the VCU obtains the external charging status of the vehicle from the vehicle's onboard charging mechanism via the CAN bus. After determining the external charging status of the vehicle, if the charging status of the vehicle is that the vehicle is being charged externally, and the second remaining power is less than the third power threshold, the VCU issues a second prompt message on whether to charge the battery vehicle at the same time. Optionally, the manner of issuing the second prompt message includes, but is not limited to: the VCU sends the second prompt message to the large screen of the vehicle's center console and the APP of the driver's mobile phone, for displaying the text on whether to charge the battery vehicle at the same time through the large screen of the vehicle's center console and the screen of the mobile phone.

[0058] Optionally, after the VCU sends the second prompt message, a second detection result of confirming the charging information is received, including: if the VCU receives information that a control in the large screen of the vehicle's center console that allows the electric vehicle to be charged simultaneously is clicked, or receives at least one of information that a control in the screen of the driver's mobile phone that allows the electric vehicle to be charged simultaneously is clicked, the detection result of the second confirmation of the charging information indicates that the electric vehicle is allowed to be charged simultaneously; if the VCU does not receive information that a control in the large screen of the vehicle's center console that allows the electric vehicle to be charged simultaneously is clicked, and does not receive information that a control in the screen of the driver's mobile phone that allows the electric vehicle to be charged simultaneously is clicked, the detection result of the second confirmation of the charging information indicates that the electric vehicle is not allowed to be charged simultaneously.

[0059] Exemplarily, if the detection result of the second confirmation charging information indicates that the battery vehicle is allowed to be charged at the same time, the VCU controls the vehicle's onboard charging mechanism to charge the battery vehicle through the power supply interface. After starting to charge the battery vehicle, the VCU receives a detection result of charging completion, wherein the detection result of charging completion is used to indicate whether the battery vehicle's power reaches the second power threshold; in response to the detection result of charging completion indicating that the battery vehicle's power reaches the second power threshold, the battery vehicle is stopped from being charged.

[0060] Exemplarily, when the communication interface of the vehicle is connected to the communication interface of the electric vehicle, a battery vehicle tire pressure detection result of the electric vehicle is received; in response to the battery vehicle tire pressure detection result including an inflation request, a third prompt message is issued to indicate whether inflation is allowed; a detection result confirming the inflation information is received, and the detection result confirming the inflation information is used to indicate whether inflation of the electric vehicle is allowed; in response to the detection result confirming the inflation information indicating that inflation of the electric vehicle is allowed, the vehicle-mounted inflation mechanism of the vehicle is controlled to inflate the electric vehicle.

[0061] Optionally, when the communication interface of the vehicle is connected to the communication interface of the battery vehicle, the VCU receives a battery vehicle tire pressure detection result of the battery vehicle, wherein the battery vehicle tire pressure detection result of the battery vehicle includes the tire pressure of the battery vehicle and may also include an inflation request.

[0062] In a possible implementation, when the communication interface of the vehicle is connected to the communication interface of the battery vehicle, the battery vehicle control system obtains the tire pressure of the battery vehicle through the tire pressure management system of the battery vehicle; in response to the tire pressure being less than the first tire pressure threshold, the battery vehicle tire pressure detection result includes an inflation request; in response to the tire pressure being greater than or equal to the first tire pressure threshold, the battery vehicle tire pressure detection result of the battery vehicle does not include an inflation request. Exemplarily, the first tire pressure threshold can be set to the tire pressure when the battery vehicle needs to be inflated based on experience.

[0063] Exemplarily, after determining the tire pressure detection result of the battery vehicle, the battery vehicle control system sends the battery vehicle tire pressure detection result and tire pressure of the battery vehicle to the communication interface of the vehicle through the communication interface of the battery vehicle, and then sends it to the VCU through the communication system of the vehicle. In response to the battery vehicle tire pressure detection result of the battery vehicle including an inflation request, the VCU issues a third prompt message on whether inflation is allowed. Optionally, the method of issuing the third prompt message includes, but is not limited to: the VCU sends the third prompt message to the large screen of the vehicle center console and the APP of the driver's mobile phone, so as to display the text on whether inflation is allowed on the large screen of the vehicle center console and the screen of the mobile phone.

[0064] In a possible implementation, after receiving the tire pressure, the VCU also sends the tire pressure to the large screen of the vehicle center console and the APP of the driver's mobile phone, so as to display the tire pressure on the large screen of the vehicle center console and the screen of the mobile phone. Optionally, the display screen of the battery vehicle can also display the tire pressure.

[0065] Optionally, after the VCU sends the third prompt message, the VCU receives a detection result confirming the inflation information, including: if the VCU receives information that a control allowing the battery vehicle to be inflated is clicked on the large screen of the vehicle's center console, or receives at least one of information that a control allowing the battery vehicle to be inflated is clicked on the screen of the driver's mobile phone, confirming that the detection result of the inflation information indicates that the battery vehicle is allowed to be inflated; if the VCU does not receive information that a control allowing the battery vehicle to be inflated is clicked on the large screen of the vehicle's center console, and does not receive information that a control allowing the battery vehicle to be inflated is clicked on the screen of the driver's mobile phone, confirming that the detection result of the inflation information indicates that the battery vehicle is not allowed to be inflated.

[0066] Exemplarily, after the VCU receives the detection result confirming the inflation information, in response to the detection result confirming the inflation information indicating that the battery vehicle is allowed to be inflated, the VCU transmits the signal ready for inflation to the communication interface of the battery vehicle through the vehicle's communication system and the vehicle's communication interface, and the communication interface of the battery vehicle sends it to the battery vehicle control system. After receiving the signal ready for inflation, the battery vehicle control system transmits the signal ready for inflation to the tire pressure management system of the battery vehicle, and the tire pressure management system of the battery vehicle enters a state ready for inflation, that is, opens the inflation port of the tire of the battery vehicle. When the tire pressure management system completes the preparation before inflation, it will feedback to the VCU the information that it is ready to accept inflation.

[0067] Exemplarily, after receiving information from the tire pressure management system indicating that it is ready to be inflated, the VCU inflates the battery vehicle through the vehicle's onboard inflation mechanism, including: the VCU controls the air pipe of the vehicle's air pump to align with the inflation port of the battery vehicle's tire, and controls the vehicle's air pump to inflate the battery vehicle's tire.

[0068] Optionally, after the electric vehicle starts to be inflated, the VCU receives a detection result of inflation completion, wherein the detection result of inflation completion is used to indicate whether the tire pressure of the electric vehicle reaches a second preset tire pressure threshold; in response to the detection result of inflation completion indicating that the tire pressure of the electric vehicle reaches the second preset tire pressure threshold, inflating the electric vehicle is stopped.
