Description

Technical Field

[0001] The present invention relates to the field of new energy vehicles, and in particular to a monitoring process method with dual positioning functions and a new energy vehicle. Background Art

[0002] With the rapid promotion of new energy vehicles around the world, real-time and reliable acquisition of vehicle location information has become one of the key technologies to ensure driving safety and rapid emergency response.

[0003] Traditional vehicle positioning systems typically place GPS or IoT positioning modules on the vehicle's perimeter, such as the bumper, trunk, or windshield trim, to monitor a single location throughout the vehicle. However, this approach suffers from the vulnerability of the locator to damage from external factors, such as scratches and collisions. Once damaged, the locator can no longer provide location information, failing to meet the requirements for high-reliability safety monitoring.

[0004] Furthermore, by fixing the positioning device inside the power battery box and connecting it to the inner wall of the battery pack box, it is possible to quickly locate a single position on the power battery. However, this locator also collects signals from a single position and relies on the power battery's own BMS system for power. If the power battery experiences thermal runaway or separates from the vehicle, the locator is likely to fail due to power loss or signal interruption, resulting in loss of positioning. Summary of the Invention

[0005] Purpose of the invention: The purpose of the present invention is to solve the defects in the prior art and provide a monitoring process method and new energy vehicle with dual positioning functions.

[0006] Technical solution:

[0007] In a first aspect, the present application proposes a monitoring process method with dual positioning functions, comprising the steps of:

[0008] Step 1: Obtain the independent vehicle positioning signal and battery positioning signal of the vehicle locator and the battery locator on the power battery through the main control chip;

[0009] Step 2: Determine whether the vehicle positioning signal and battery positioning signal are successfully obtained. If successful, perform deviation position detection. If failed, proceed to the next step;

[0010] Step 3: If the vehicle positioning signal is successfully acquired but the battery positioning signal is not, the process proceeds to power battery separation detection. If the vehicle positioning signal is successfully acquired but the battery positioning signal is not, the process proceeds to collision position detection.

[0011] Among them, when abnormalities occur in deviation position detection, power battery detachment detection, and collision position detection, an early warning signal is issued.

[0012] Preferably, the deviation position detection includes the following steps:

[0013] Determine the deviation distance between the vehicle positioning position and the battery positioning position through the vehicle positioning signal and the battery positioning signal;

[0014] When the deviation between the vehicle positioning position and the battery positioning position reaches the preset threshold range, the position deviation warning is triggered and the deviation time is calculated;

[0015] Determine whether the position deviation and deviation time reach the preset threshold at the same time. If so, the main control chip triggers an early warning reminder. If not, continue to perform deviation position detection.

[0016] Preferably, when the deviation distance between the vehicle positioning position and the battery positioning position reaches a preset threshold range, the position deviation warning is triggered at the same time, and the deviation time is calculated; it is determined whether the position deviation warning and the deviation time reach the preset threshold. If so, the main control chip triggers a warning reminder; if not, the deviation position detection is continued, including the following formula:

[0017] ;

[0018] Wherein, ΔP is the deviation distance, Δt is the deviation time, w1 and w2 are the position deviation thresholds, and t1 and t2 are the time deviation thresholds.

[0019] Preferably, when the primary warning is triggered, the main control chip issues a primary warning reminder;

[0020] When a medium-level warning is triggered, the main control chip issues a medium-level warning reminder;

[0021] When a high-level warning is triggered, the main control chip issues a high-level warning reminder.

[0022] Preferably, the primary warning reminder includes prompting via indicator lights and sending push messages;

[0023] The intermediate warning reminder includes the use of indicator lights, push notifications, automatic double flash control of the vehicle, speed control, and pop-up reminders to indicate whether a preset emergency plan for handling danger is needed;

[0024] The advanced early warning reminder includes starting a preset danger occurrence process.

[0025] Preferably, the power battery detachment detection includes the following steps:

[0026] When the battery positioning signal acquisition fails, determine whether the battery locator is working properly. If not, obtain the vehicle positioning signal of the vehicle locator and issue a command to make the vehicle stop after driving a certain distance and check the vehicle. If yes, proceed to the next step.

[0027] Obtain whether the current power battery temperature and voltage exceed the preset threshold. If not, issue a command for the vehicle to drive to a safe position or stop and inspect the vehicle. If so, immediately issue a preset danger warning.

[0028] Preferably, the collision position detection includes the following steps:

[0029] When the vehicle positioning signal fails to be acquired and only the battery positioning signal can be acquired, the power battery positioning signal is acquired to trigger a primary warning reminder;

[0030] The vehicle is instructed to stop after driving for a period of time and the vehicle is inspected.

[0031] In a first aspect, in some embodiments, a new energy vehicle is provided, including the method described in the above embodiment, including:

[0032] Battery locator, vehicle locator, main control chip and alarm module;

[0033] Wherein, the vehicle-mounted locator is arranged on the periphery of the vehicle;

[0034] The battery locator is arranged inside the power battery pack;

[0035] The battery locator and the vehicle locator are respectively connected to the main control chip for communication.

[0036] The alarm module is connected to the main control chip to send emergency signals;

[0037] The main control chip is connected to the cloud monitoring system.

[0038] Preferably, the battery locator and the vehicle locator are both powered by an independent low-voltage battery system. When the vehicle is separated from the power battery, the battery locator can directly upload location information to the cloud monitoring system.

[0039] Preferably, the main control chip includes a difference analysis unit for calculating and evaluating the difference between the vehicle positioning signal and the battery positioning signal, and switching the positioning signal source and triggering an alarm according to the evaluation result.

[0040] Beneficial effects:

[0041] Through dual signal collection from the vehicle body locator and the battery locator, two independent sets of position information can be obtained simultaneously. Positioning deviations can be further calibrated through difference analysis, significantly improving the accuracy and reliability of overall vehicle positioning.

[0042] When a vehicle peripheral locator is damaged due to a collision or a battery locator loses power due to thermal runaway and loses signal, another locator can still be relied upon to continue providing location information, ensuring uninterrupted monitoring and effectively improving the robustness and stability of the system.

[0043] This application continuously monitors the status and difference changes of dual positioning signals, and can automatically trigger an alarm process when positioning fails or the signal is abnormal. Whether in normal driving, external collision, power battery separation from the vehicle, and other working conditions, the monitoring process can be flexibly switched according to the status of the dual positioning signals to ensure that the position tracking capability can be maintained in various emergency situations, meeting the safety monitoring needs of new energy vehicles in extreme environments.

[0044] Even if the vehicle is separated from the power battery assembly due to a malfunction or accident, the battery locator can still independently and continuously report its own location to the cloud to assist in search and rescue and fault analysis, and further improve the safety management system of the vehicle and battery.

[0050] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the specific embodiments of the drawings.

[0051] Example 1

[0052] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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 work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be the common meanings understood by people with ordinary skills in the field to which the present invention belongs. The words "including" and similar words used in this article mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0053] In view of the problems existing in the existing technology, such as Figure 1-4 As shown, the present invention provides a monitoring process method with dual positioning functions, comprising the steps of:

[0054] Step 1: The main control chip 303 obtains the vehicle positioning signal and battery positioning signal of the vehicle locator 302 and the battery locator 301 on the power battery respectively;

[0055] Vehicle positioning signal: comes from a vehicle-mounted GPS locator installed on the periphery of the vehicle (such as the bumper, trunk, or windshield molding);

[0056] Battery positioning signal: comes from the battery GPS locator installed in the power battery assembly (or inside the BMS). Both are powered by low-voltage batteries to ensure that the position information can still be independently reported in the event of power battery failure or vehicle collision.

[0057] Step 2: Determine whether the vehicle positioning signal and battery positioning signal are successfully obtained. If successful, perform deviation position detection. If failed, proceed to the next step;

[0058] After completing the acquisition, the main control chip 303 first determines the acquisition status of the two signals:

[0059] All are obtained successfully → enter "Deviation Position Detection";

[0060] Only the vehicle signal is successful and the battery signal fails → enter "Power Battery Disconnection Detection";

[0061] Only the battery signal is successful and the vehicle signal fails → enter "Collision Position Detection";

[0062] Failure in both acquisitions → Directly triggers an abnormal warning (the system loses all location information).

[0063] Step 3: If the vehicle positioning signal is successfully acquired but the battery positioning signal is not, the process proceeds to power battery separation detection. If the vehicle positioning signal is successfully acquired but the battery positioning signal is not, the process proceeds to collision position detection.

[0064] Among them, when abnormalities occur in deviation position detection, power battery detachment detection, and collision position detection, an early warning signal is issued.

[0065] In some specific embodiments, combined Figure 2 , the deviation position detection includes the following steps:

[0066] Determine the deviation distance between the vehicle positioning position and the battery positioning position through the vehicle positioning signal and the battery positioning signal;

[0067] When the deviation distance between the vehicle positioning position and the battery positioning position reaches the preset threshold range, a position deviation warning is triggered, and the deviation time is started to be calculated;

[0068] Judge whether the position deviation and the deviation time reach the preset threshold at the same time. If so, the main control chip 303 triggers a warning reminder. If not, continue to detect the deviation position.

[0069] In some specific embodiments, when the deviation distance between the vehicle positioning position and the battery positioning position reaches the preset threshold range, a position deviation warning is triggered, and the deviation time is started to be calculated; judge whether the position deviation warning and the deviation time reach the preset threshold. If so, the main control chip 303 triggers a warning reminder. If not, continue to detect the deviation position, including the following formula:

[0070] ;

[0071] Among them, ΔP is the deviation distance, Δt is the deviation time, w1 and w2 are the position deviation thresholds respectively, and t1 and t2 are the time deviation thresholds respectively.

[0072] In some specific embodiments, when the primary warning is triggered, the main control chip 303 issues a primary warning reminder;

[0073] When the intermediate warning is triggered, the main control chip 303 issues an intermediate warning reminder;

[0074] When the high-level warning is triggered, the main control chip 303 issues a high-level warning reminder.

[0075] Specifically, recalculate ΔP and Δt every set period, and determine the warning level according to the above formula:

[0076] If both ΔP < w1 and Δt < t1 are satisfied, maintain the "primary warning";

[0077] If both w1 ≤ ΔP < w2 and t1 ≤ Δt < t2 are satisfied, upgrade to the "intermediate warning";

[0078] If both ΔP ≥ w2 and Δt ≥ t2 are satisfied, upgrade to the "high-level warning" and trigger the main control chip 303 to send a serious deviation warning to the cloud and the local alarm module 304;

[0079] If it is found that ΔP < w1 in any detection, the warning level and the timer can be reset, restored to the non-deviation state, and continue periodic monitoring. [[ID=:39]]

[0080] In some specific embodiments, the primary warning reminder includes reminder through an indicator light and sending a message push;

[0081] The intermediate warning reminder includes flashing an indicator light, sending a message push reminder, controlling the vehicle's automatic double flashing, controlling the vehicle speed, and popping up a reminder of whether to preset a danger handling plan;

[0082] The advanced warning reminder includes starting the preset danger handling.

[0083] Specifically, the primary warning response

[0084] Trigger condition: Detect that ΔP≥w1 and Δt<t1, Response measure: The dashboard or in-vehicle indicator light flashes to indicate that the position deviation has reached the primary threshold;

[0085] Send a message push to the owner's mobile phone or in-vehicle infotainment system, reminding "Position deviation - please check";

[0086] Intermediate warning response

[0087] Trigger condition: Detect that w1≤ΔP<w2 and t1≤Δt<t2.

[0088] Response measure: Keep the indicator light flashing and continue to send a message push;

[0089] Control the vehicle to automatically turn on the double flashing warning light to alert surrounding vehicles;

[0090] According to the current vehicle speed limit strategy, moderately reduce the driving speed or issue a prompt of "Please drive slowly";

[0091] Pop up a confirmation dialog box of the preset "Danger handling plan", and the user can immediately select whether to execute it (for example: pull over nearby, automatically navigate to a safe area, etc.).

[0092] Advanced warning response

[0093] Trigger condition: Detect that ΔP≥w2 and Δt≥t2.

[0094] Response measure: Immediately start the configured "Danger handling plan", including but not limited to:

[0095] Automatically decelerate and stop at a safe area by the roadside;

[0096] Trigger the in-vehicle emergency call (eCall) to call the cloud service desk or a preset emergency contact;

[0097] Simultaneously send assistance requests to public emergency systems such as traffic management, fire departments, and hospitals;

[0098] Turn on the double flashing of the whole vehicle, unlock the doors and turn on the interior lighting to facilitate rescue.

[0099] In some specific embodiments, in combination with Figure 4, the power battery detachment detection includes the following steps:

[0100] When the battery positioning signal acquisition fails, it is determined whether the battery locator 301 is working properly. Preferably, the current or voltage supplied to the battery locator 301 can be monitored to determine whether the battery locator 301 is working properly. If not, the vehicle positioning signal of the vehicle locator 302 is acquired, and a command is issued to stop the vehicle after driving a certain distance and inspect the vehicle. If yes, proceed to the next step.

[0101] Obtain whether the current power battery temperature and voltage exceed the preset threshold. If not, issue a command for the vehicle to drive to a safe position or stop and inspect the vehicle. If so, immediately issue a preset danger warning.

[0102] Specifically, if the power battery encounters thermal runaway, the power battery will be separated. The specific positioning detection is as follows:

[0103] Step 1: Locator function self-test

[0104] Detect the hardware and software status of the battery locator 301 (such as self-test feedback code, power supply voltage, etc.);

[0105] If the locator is not functioning properly (hardware failure or software crash), it may be a malfunction of the locator itself, so proceed to step 2.

[0106] If the locator self-test is normal, it means that the signal loss may be caused by the battery being separated from the vehicle body. Skip to step 3.

[0107] Step 2: Vehicle positioning replacement and driving inspection, switch to the vehicle locator 302 to collect the vehicle positioning signal;

[0108] Send the "move X meters and stop" command to the vehicle control unit to confirm the vehicle movement and the working status of the positioning module;

[0109] After the vehicle stops, the driver will be notified or the doors and warning lights will be automatically opened to notify the vehicle body and battery compartment inspection;

[0110] After the inspection is completed, if the locator problem is solved (reset or replaced), the process ends; otherwise, the alternative positioning is continued and the battery locator 301 is retried regularly.

[0111] Step 3: Determine the battery status threshold and read the current temperature T and voltage V of the power battery;

[0112] and the preset safety threshold T th 、V th Make a comparison;

[0113] If T <T th And V <Vth , indicating that although the battery signal is lost, the status is still controllable, and proceed to step 4;

[0114] If T≥T th or V ≥ V th , indicating that the battery may have thermal runaway or serious failure, go directly to step 5.

[0115] Step 4: Drive safely or park to check

[0116] Send the vehicle control unit the command of "drive to the nearest safe position or stop smoothly on the spot";

[0117] After parking, the driver will be prompted to conduct a comprehensive inspection through the in-car radio or instrument panel;

[0118] The background continues to try to re-establish the battery locator 301 connection. If it is restored, normal monitoring is resumed; otherwise, the vehicle positioning is retained and the vehicle remains parked until manual intervention is performed.

[0119] Step 5: Immediate Danger Warning

[0120] When the battery temperature or voltage exceeds the limit, the tracker will trigger the "Danger Warning" process regardless of the tracker status:

[0121] The local buzzer and indicator light flash;

[0122] Send emergency help messages to the cloud monitoring platform and the driver's mobile phone;

[0123] Activate pre-set emergency response plans (such as automatic power off, emergency call to the service desk, double flash for assistance, etc.);

[0124] Guide rescue forces to quickly move to the last valid positioning coordinates for intervention.

[0125] In some specific embodiments, combined Figure 3 , collision position detection includes the following steps:

[0126] When the vehicle positioning signal fails to be acquired and only the battery positioning signal can be acquired, the power battery positioning signal is acquired to trigger a primary warning reminder;

[0127] The vehicle is instructed to stop after driving for a period of time and the vehicle is inspected.

[0128] Specifically, when the vehicle positioning signal acquisition fails and only the battery positioning signal is available, the system performs collision position detection according to the following steps:

[0129] The trigger condition is determined, and if the signal of the vehicle locator 302 is interrupted while the signal of the battery locator 301 is reported normally, it is determined that a vehicle peripheral collision may have occurred.

[0130] Obtain battery location and issue a primary warning, and read the current power battery location coordinates;

[0131] A "primary warning reminder" is issued by flashing indicator lights in the car and pushing messages to indicate that there is a locator abnormality or a possible vehicle collision.

[0132] The driving detection command is issued, sending a "stop automatically after driving a preset distance (e.g. 10 meters)" command to the vehicle control unit;

[0133] Continuously monitor the stability of the battery positioning signal during driving to ensure that the vehicle can drive as instructed.

[0134] Stop and check the vehicle, and the vehicle will automatically stop after completing the journey;

[0135] A pop-up inspection prompt will be displayed to the driver, instructing them to conduct a visual or tool inspection of the vehicle's peripheral locators, front and rear bumpers, and body damage;

[0136] After the inspection, if the locator returns to normal, continue to the deviation position detection; otherwise, keep the battery position and retry the vehicle locator 302 regularly.

[0137] In some specific embodiments, the present application proposes a new energy vehicle, combined with Figure 5 , including the method described in the above embodiment, including:

[0138] Battery locator 301, vehicle locator 302, main control chip 303 and alarm module 304;

[0139] Wherein, the vehicle-mounted locator 302 is arranged on the periphery of the vehicle;

[0140] The battery locator 301 is provided inside the power battery pack;

[0141] The battery locator 301 and the vehicle locator 302 are respectively connected to the main control chip 303 for communication.

[0142] The alarm module 304 is connected to the main control chip 303 and is used to send emergency signals;

[0143] The main control chip 303 is connected to the cloud monitoring system.

[0144] Specifically, the vehicle locator 302 is installed on the periphery of the vehicle (e.g., the bumper, trunk, windshield molding, etc.) to collect the vehicle's position data in real time;

[0145] The battery locator 301 is integrated and arranged inside the power battery pack to independently collect the position data of the power battery itself;

[0146] The main control chip 303 establishes communication connections with the vehicle locator 302 and the battery locator 301 respectively, and is responsible for obtaining two positioning signals in parallel, performing deviation detection, collision detection, and battery detachment detection processes, and triggering corresponding warnings based on the detection results;

[0147] The alarm module 304 is directly connected to the main control chip 303 and is used to issue a local emergency signal (indicator light, buzzer) or activate the double flash lights, vehicle speed control, etc. when an abnormality is detected (such as continuous deviation exceeding the limit, collision or battery disconnection);

[0148] Cloud monitoring system interface, the main control chip 303 maintains real-time connection with the cloud monitoring platform through vehicle-mounted communications (such as 4G / 5G or IoT network), uploading positioning data, warning events and vehicle status to facilitate remote monitoring and emergency dispatch.

[0149] In some specific embodiments, the battery locator 301 and the vehicle locator 302 are both powered by independent low-voltage battery systems. When the vehicle is separated from the power battery, the battery locator 301 can directly upload location information to the cloud monitoring system, while the vehicle locator 302 can upload location information to the cloud monitoring system through the main control chip 303.

[0150] Specifically, in the new energy vehicle system, both the battery locator 301 and the vehicle locator 302 are equipped with independent low-voltage battery power supply modules to ensure continuous positioning and communication under abnormal working conditions:

[0151] Independent power supply: Each locator has its own low-voltage power supply, which is physically isolated from the main power battery pack and the main power system of the vehicle. It can work independently when the vehicle is powered off or the power battery fails.

[0152] Separation state upload: When the vehicle is separated from the power battery pack due to collision or failure, the battery locator 301 relies on the built-in low-voltage power supply to directly upload the latest location information to the cloud monitoring system through its communication unit (such as 4G / 5G or NB-IoT);

[0153] On-board upload, at the same time, the on-board locator 302 is also powered by its own low-voltage battery. After the vehicle's main control power is restarted or the communication is restored, the vehicle's positioning signal is synchronized to the cloud monitoring platform through the main control chip 303 and the on-board communication module through the communication link with the main control chip 303.

[0154] In some specific embodiments, the main control chip 303 includes a difference analysis unit for calculating and evaluating the difference between the vehicle positioning signal and the battery positioning signal, and switching the positioning signal source and triggering an alarm according to the evaluation result.

[0155] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention should be covered by the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
