Description

Technical Field

[0001] The present invention relates to the technical field of intelligent control of electric vehicles, and in particular to a high-voltage power-up and power-down control method and related equipment based on intelligent power replenishment of an automobile. Background Art

[0002] For new energy vehicles, the intelligent charging function is a very common feature. Therefore, its actual use plays a vital role in the user's driving experience. The necessary condition for the normal operation of the intelligent charging function is that the vehicle is normally connected to high voltage. Under normal intelligent charging conditions, the 12V battery sensor detects the power level of the low-voltage battery in real time. When the low-voltage battery SOC falls below a certain value, the vehicle activates the intelligent charging function to replenish the low-voltage battery to prevent it from being too low. If the vehicle cannot normally connect to high voltage at this time, the function will not work properly, causing the low-voltage battery to be too low, which will affect the user's normal use of the vehicle. Summary of the Invention

[0003] The purpose of the present invention is to provide a high-voltage power-up and power-down control method and related equipment based on intelligent automobile power replenishment to solve the technical problem of how to control the high-voltage power-up and power-down based on intelligent automobile power replenishment.

[0004] The present invention is achieved through the following technical solutions:

[0005] In the first aspect, the present invention provides a high-voltage power-up and power-down control method based on intelligent vehicle power replenishment, comprising:

[0006] Obtain the low-voltage battery power, judge the obtained low-voltage battery power, obtain a judgment result, and send an intelligent charging request to the VCU for intelligent charging according to the judgment result;

[0007] Monitor the VCU intelligent power replenishment status to obtain monitoring results, and control the high voltage up and down through the VCU according to the monitoring results.

[0008] Preferably, the power of the low-voltage battery is obtained, and the obtained power of the low-voltage battery is judged to obtain a judgment result. The specific process is as follows:

[0009] Set battery level threshold;

[0010] The obtained low-voltage battery power is judged, and the judgment results include whether the low-voltage battery power is higher than a battery power threshold or whether the low-voltage battery power is lower than a battery power threshold.

[0011] Furthermore, in the step of sending an intelligent power replenishment request to the VCU for intelligent power replenishment according to the judgment result, the specific process is as follows:

[0012] When the low-voltage battery power level is lower than the battery power threshold, an intelligent power replenishment request is sent to the VCU, which then sends a high-voltage instruction and replenishes the low-voltage battery power.

[0013] When the low-voltage battery power level is higher than the battery power threshold, the low-voltage battery operates normally.

[0014] Preferably, in the step of monitoring the VCU intelligent power replenishment state to obtain a monitoring result, the monitoring result includes a normal state of the intelligent power replenishment function and an abnormal state of the intelligent power replenishment function;

[0015] Among them, the normal intelligent charging function means that after the intelligent charging request is issued, the VCU normally sends the high-voltage instruction and the vehicle normally supplies high voltage;

[0016] The abnormal state of the intelligent charging function is that after the intelligent charging request is issued, the VCU does not normally send the high-voltage instruction or the vehicle does not normally connect to the high voltage.

[0017] Furthermore, in the step of controlling the high voltage up and down through the VCU according to the monitoring results, when the intelligent power replenishment function is in an abnormal state, the sending of the intelligent power replenishment request is suspended, and the intelligent power replenishment request is sent cyclically as 1 after the VCU goes into sleep mode. When the number of cycles reaches the threshold, the backup intelligent power replenishment request is triggered, and the fault level of the entire vehicle is determined. If the fault level of the entire vehicle is lower than the threshold level, the backup intelligent power replenishment request is sent to the VCU to increase the high voltage of the entire vehicle and complete the intelligent power replenishment function. Otherwise, the intelligent power replenishment function is stopped.

[0018] Furthermore, when the standby intelligent charging request signal is set to 1 and the vehicle is in a high-voltage connection state, a message indicating successful intelligent charging is sent to the user's mobile phone through the telematics box, along with vehicle fault information.

[0019] When the standby intelligent charging request signal is set to 1 and the vehicle is in a high-voltage disconnected state, the telematics box sends a message indicating that the intelligent charging has failed to complete, and also sends the user's vehicle fault information.

[0020] In the second aspect, the present invention also provides a high-voltage power-up and power-down control system based on intelligent vehicle power replenishment, including:

[0021] The first control module is used to obtain the low-voltage battery power, judge the obtained low-voltage battery power, obtain a judgment result, and send an intelligent charging request to the VCU for intelligent charging according to the judgment result;

[0022] The second control module is used to monitor the VCU intelligent power replenishment status to obtain monitoring results, and to control the high voltage up and down through the VCU according to the monitoring results.

[0023] In a third aspect, the present invention also provides a mobile terminal comprising a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the steps of the high-voltage power-on and power-off control method based on intelligent vehicle power replenishment as described above are implemented.

[0024] In a fourth aspect, the present invention further provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the steps of the high-voltage power-up and power-down control method based on intelligent vehicle power replenishment as described above.

[0025] In a fifth aspect, the present invention further provides a computer program product comprising computer instructions, wherein the computer instructions instruct a computing device to execute operations corresponding to the high-voltage power-up and power-down control method based on intelligent vehicle power replenishment as described above.

[0026] Compared with the prior art, the present invention has the following beneficial technical effects:

[0027] This invention provides a high-voltage power-up and power-down control method based on intelligent vehicle charging. The method obtains the low-voltage battery charge, determines the obtained low-voltage battery charge, obtains a determination result, and sends an intelligent charging request to the VCU for intelligent charging based on the determination result. The VCU's intelligent charging status is monitored to obtain a monitoring result, and high-voltage power-up and power-down control is performed through the VCU based on the monitoring result. By obtaining and determining the low-voltage battery charge in real time, an intelligent charging request can be promptly sent when the battery is low, effectively avoiding problems such as vehicle startup failure or control unit malfunction caused by low-voltage battery charge, thereby improving vehicle power safety.

[0028] Furthermore, after the intelligent charging request is sent to the VCU, the VCU will intelligently determine whether to charge based on the current status of the power battery and the power level of the low-voltage battery, avoiding unnecessary damage to the power battery due to blind charging, while also ensuring sufficient power in the low-voltage battery.

[0029] Furthermore, after monitoring the VCU's intelligent charging status, the VCU controls the high voltage up and down according to the monitoring results, realizing intelligent management of the high voltage system. This process optimization makes the high voltage system's charging and down time faster and more accurate, improving the vehicle's responsiveness and driving efficiency.

[0030] Furthermore, the present invention does not require additional hardware costs. By simply adding corresponding logic in the VCU application layer through the existing CAN network signal, the success rate of upper and lower high voltage under intelligent power replenishment conditions can be improved, thereby improving the user's car experience.

[0034] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0035] The purpose of the present invention is to provide a high-voltage power-up and power-down control method and related equipment based on intelligent automobile power replenishment to solve the technical problem of how to control the high-voltage power-up and power-down based on intelligent automobile power replenishment.

[0036] The present invention is described in further detail below with reference to the accompanying drawings:

[0037] Example 1

[0038] See also Figure 1 In one embodiment of the present invention, a method for controlling high-voltage power on and off based on intelligent vehicle power replenishment is provided, comprising the following steps:

[0039] Step 1: Obtain the power of the low-voltage battery, judge the obtained power of the low-voltage battery, obtain a judgment result, and send an intelligent charging request to the VCU for intelligent charging according to the judgment result;

[0040] Specifically, the low-voltage battery power is obtained, and the obtained low-voltage battery power is judged to obtain a judgment result. The specific process is as follows:

[0041] Set battery level threshold;

[0042] The obtained low-voltage battery power is judged, and the judgment results include whether the low-voltage battery power is higher than a battery power threshold or whether the low-voltage battery power is lower than a battery power threshold.

[0043] In this embodiment, the battery power threshold is set based on the specifications and performance of the low-voltage battery and the actual power demand of the vehicle. This threshold is usually used to determine whether the low-voltage battery needs to be replenished.

[0044] The current charge level of the low-voltage battery is obtained in real time through the vehicle's internal power monitoring system or sensors. This process may involve measuring and calculating parameters such as battery voltage and current.

[0045] The low-voltage battery power obtained in real time is compared with a set battery power threshold.

[0046] If the low-voltage battery charge is higher than the battery charge threshold, the battery charge is considered sufficient and no intelligent charging is required.

[0047] If the low-voltage battery power level is lower than the battery power threshold, it is considered that the battery power is insufficient and a smart charging request needs to be sent to the VCU (vehicle control unit) for smart charging.

[0048] In this embodiment, the vehicle's internal power monitoring and determination system continuously monitors the low-voltage battery's charge level and compares it to a preset charge threshold. This process enables the system to accurately determine the battery's charge status, providing a basis for subsequent recharging operations. When the system determines that the low-voltage battery's charge level is below the charge threshold, it automatically generates an intelligent recharge request and sends it to the VCU. The VCU, as the vehicle's control center, is responsible for receiving and processing this request. Upon receiving the intelligent recharge request, the VCU intelligently determines whether to recharge based on the current vehicle status, the power battery's charge level, and the low-voltage battery's needs. If recharging is necessary, the VCU controls the power battery to transfer an appropriate amount of power to the low-voltage battery to ensure sufficient charge. During the intelligent recharge process, the VCU also controls the power on and off of the high-voltage system based on the monitoring results. This control process is designed to ensure the safety and stability of the high-voltage system during the recharge process, preventing damage to the vehicle and personnel.

[0049] Step 2: Monitor the VCU intelligent power replenishment status to obtain monitoring results, and control the high voltage up and down through the VCU according to the monitoring results.

[0050] Specifically, in the step of monitoring the VCU intelligent power replenishment state to obtain a monitoring result, the monitoring result includes a normal state of the intelligent power replenishment function and an abnormal state of the intelligent power replenishment function;

[0051] Among them, the normal intelligent charging function means that after the intelligent charging request is issued, the VCU normally sends the high-voltage instruction and the vehicle normally supplies high voltage;

[0052] The abnormal state of the intelligent charging function is that after the intelligent charging request is issued, the VCU does not normally send the high-voltage instruction or the vehicle does not normally connect to the high voltage.

[0053] Among them, in the step of controlling the high voltage up and down through the VCU according to the monitoring results, when the intelligent power replenishment function is in an abnormal state, the sending of the intelligent power replenishment request is suspended, and the intelligent power replenishment request is sent cyclically after the VCU is in sleep mode as 1. When the number of cycles reaches the threshold, the backup intelligent power replenishment request is triggered, and the fault level of the entire vehicle is determined. If the fault level of the entire vehicle is lower than the threshold level, the backup intelligent power replenishment request is sent to the VCU to increase the high voltage of the entire vehicle and complete the intelligent power replenishment function. Otherwise, the intelligent power replenishment function is stopped.

[0054] Specifically, when the standby intelligent charging request signal is set to 1 and the vehicle is in a high-voltage connection state, a message indicating that the intelligent charging is successful is sent to the user's mobile phone through the telematics box, and the user's vehicle fault information is also sent;

[0055] When the standby intelligent charging request signal is set to 1 and the vehicle is in a high-voltage disconnected state, the telematics box sends a message indicating that the intelligent charging has failed to complete, and also sends the user's vehicle fault information.

[0056] In this embodiment, when the VCU performs abnormal processing in the high voltage upper and lower control according to the monitoring results, when the intelligent power replenishment function is in an abnormal state, the system waits for the VCU to enter the sleep state and then starts to cyclically send the intelligent power replenishment request.

[0057] When the number of cycles reaches a preset threshold (such as 3 times), a backup intelligent power replenishment request is triggered.

[0058] After triggering the backup intelligent power replenishment request, the system first determines the fault level of the vehicle.

[0059] If the vehicle fault level is lower than the preset threshold level, it indicates that the fault does not affect the execution of the intelligent charging function. At this time, a backup intelligent charging request is sent to the VCU to force the vehicle to be on high voltage and complete the intelligent charging function.

[0060] If the vehicle fault level is higher than or equal to the preset threshold level, it indicates that the fault is serious and may affect the safety and effectiveness of the intelligent charging function. At this time, the system stops the intelligent charging function to avoid potential risks.

[0061] In this embodiment, when the standby intelligent charging request signal is set to 1 and the vehicle is in a high-voltage connection state, a message indicating successful intelligent charging is sent to the user's mobile phone application via the telematics box (TBOX), along with vehicle fault information, to remind the user to carry out timely maintenance.

[0062] When the standby intelligent charging request signal is set to 1 and the vehicle is in a high-voltage disconnected state, a message indicating intelligent charging failure is also sent to the user's mobile phone through TBOX, along with vehicle fault information, to remind the user that the vehicle has a serious fault and needs to be repaired as soon as possible.

[0063] In summary, this embodiment provides a high-voltage power-up and power-down control method based on intelligent vehicle charging. The method obtains the low-voltage battery charge, makes a judgment on the obtained low-voltage battery charge, obtains a judgment result, and sends an intelligent charging request to the VCU for intelligent charging based on the judgment result. The VCU intelligent charging status is monitored to obtain a monitoring result, and high-voltage power-up and power-down control is performed through the VCU based on the monitoring result. By obtaining the low-voltage battery charge in real time and making a judgment, an intelligent charging request can be sent in a timely manner when the charge is low, effectively avoiding problems such as the vehicle being unable to start or the control unit not being able to work properly due to low-voltage battery charge, thereby improving the safety of vehicle power use.
