Description

Technical Field

[0001] The present invention relates to the field of vehicle control technology, and in particular to an energy-saving control method and system for a fuel vehicle. Background Art

[0002] With the development of vehicle technology, the power load of large vehicles such as heavy trucks is increasing, which brings great challenges to the use of batteries. Among them, the power load can be independent heat sources, parking air conditioners and high-power inverters. The improvement of electrical configuration has increased the requirements for battery power. In order to prevent the battery from running out of power and affecting the battery life, energy-saving management of the vehicle is required.

[0003] In the existing energy-saving management methods, different vehicle network management solutions are used to configure and manage the various ECUs of the vehicle network and coordinate them, so that the ECUs of the vehicle can sleep and wake up in an orderly manner, so as to achieve the purpose of reducing the static power consumption of the vehicle and realize energy-saving management in the sleep mode of the vehicle. Although this solution controls the sleep and wake-up of each ECU of the vehicle through network management, reducing the static power consumption of the vehicle in the sleep state and the power consumption of unnecessary ECU wake-up, this solution is limited to the sleep state of the vehicle and is not applicable to other working conditions of the vehicle.

[0004] In the existing energy-saving management method, the battery status is also monitored in real time through intelligent battery sensors, and the monitored battery status information is actively sent to the instrument display through the bus to remind the user, or support the user to query the battery status in real time. This solution is mainly used in the vehicle power-on environment and is relatively dependent on the user's operation. When an abnormal problem is detected in the battery status, the user needs to cooperate and take corresponding measures in time to respond to the abnormal reminder. In this way, the user is very likely to ignore or delay the handling of the abnormal reminder, which will further damage the battery life and cause unnecessary economic losses. Summary of the invention

[0005] The purpose of the present invention is to address the defects of the prior art and provide an energy-saving control method and system for fuel vehicles, so that the battery status information of the whole vehicle can be monitored in real time when the vehicle is in different operating scenarios. According to the different states of the battery, a combination of early warning notification and forced intervention is adopted to avoid the battery life being damaged due to users ignoring the early warning, and reduce the problems of towing, emergency treatment, economic loss, time loss, etc. caused by battery damage due to excessive power loss.

[0006] The present invention provides a fuel vehicle energy-saving control method, comprising:

[0007] Real-time monitoring of battery parameters;

[0008] The battery parameters are compared and analyzed with the preset values, and warnings of different urgency levels are issued according to different analysis results. The warnings of different urgency levels include at least level one, level two and level three in order of urgency from low to high. The level one and level two warnings are executed in the form of active notifications, and the warnings are canceled after the user takes energy-saving intervention measures. The level three warning is executed in the form of active notifications, and the vehicle is actively controlled to enter an energy-saving mode.

[0009] Preferably, when the user does not take energy-saving intervention measures within a specified period of time after the first-level warning is output, or when the user does not immediately take energy-saving intervention measures after the second-level warning is output, the vehicle is actively controlled to enter the energy-saving mode.

[0010] Preferably, the battery parameters include the battery remaining power percentage SOC, the cold start current value CCA and the battery terminal voltage value U, and the comparison and analysis of the monitored values ​​with the preset values ​​includes:

[0011] When SOC≥S1, or U≥U1 and CCA≥C1, no warning is triggered;

[0012] When S2≤SOC<S1, or U2≤U<U1 and CCA≥C1, the first level warning is triggered;

[0013] When S3≤SOC<S2 and U3≤U<U2, or C2≤CCA<C1, the second level warning is triggered;

[0014] When SOC≤S3 and U<U3, or CCA<C2, the third-level warning is triggered;

[0015] Among them, S1, S2, S3, U1, U2, U3, C1, and C2 are all preset values, and S3<S2<S1, U3<U2<U1, and C2<C1.

[0016] Preferably, the energy-saving intervention measures taken by the user include actively starting the vehicle, or shutting down high-power electrical equipment powered by the battery, or cutting off the drive output of some ECU high-power actuators.

[0017] Preferably, in the energy-saving mode, the input power of the high-power electrical equipment powered by the battery is cut off or the drive output of some ECU high-power actuators is cut off.

[0018] Preferably, when the vehicle is in the energy-saving mode, if the vehicle enters the starting state, the energy-saving mode is exited.

[0019] Preferably, the whole vehicle current is also monitored. When the whole vehicle current is monitored to be less than a preset current value, the intelligent battery sensor IBS stops sending the detected battery parameter message information and enters a dormant state; when the whole vehicle current is monitored to be greater than or equal to the preset current value, the intelligent battery sensor IBS broadcasts the battery parameter message to the vehicle network at a specified period.

[0020] Preferably, when the IBS enters the dormant state, the battery parameters are still monitored, and when the battery parameters reach the warning standard, the current battery parameters are sent to the vehicle network.

[0021] Preferably, the active notification includes sending a warning message to a vehicle-mounted display screen and / or a mobile phone APP, and the warning message is output in the form of text or sound and light.

[0022] The present invention also provides a fuel vehicle energy-saving control system, comprising:

[0023] Acquisition module, used for real-time monitoring of battery parameters;

[0024] The early warning analysis module is used to compare and analyze the battery parameters with the preset values, and to issue early warnings of different urgency levels according to different analysis results. The early warnings of different urgency levels include at least level one, level two and level three in order of urgency from low to high. The level one and level two early warnings are executed in the form of active notifications and cancellation of the early warnings after the user takes energy-saving intervention measures. The level three early warning is executed in the form of active notifications and active control of the vehicle to enter energy-saving mode.

[0025] The beneficial effects of the present invention are:

[0026] 1. This method enables the vehicle to monitor the battery status information of the whole vehicle in real time under different usage scenarios, not limited to the whole vehicle sleep scenario or the whole vehicle working scenario, and manages the power consumption of the whole vehicle in various application scenarios to the greatest extent to ensure the service life of the vehicle battery. At the same time, the battery parameters are compared and analyzed with the preset values, and different emergency warnings are issued according to different analysis results. For the warnings of different emergency levels, active notifications are adopted and the warnings or active notifications are cancelled after the user takes energy-saving intervention measures, and the vehicle is actively controlled to enter the energy-saving mode. In the energy-saving mode, the energy-saving management ECU will actively trigger the energy-saving instruction, so that some ECU functions on the vehicle are restricted, the power supply of high-power electrical equipment is disconnected, and the battery power consumption of the whole vehicle is minimized, so as to ensure that the vehicle has enough power to start normally and reduce the various losses caused by the deep power loss of the vehicle battery. Avoid the damage to the battery life caused by the user's subjective or non-subjective neglect or delay in handling the alarm reminder, and reduce the high-cost economic losses and time loss caused by the battery damage due to excessive power loss.

[0027] 2. Comprehensive analysis of the battery status is performed using the battery remaining power percentage SOC, cold start current value CCA and battery terminal voltage value U. Compared with the existing form of monitoring and warning of SOC alone, it is more in line with the actual status of the battery and its warning strategy is more rigorous. Based on the judgment and processing of the battery SOC, CCA, U value and other parameter information detected by the smart battery sensor by the energy-saving management ECU, when abnormal problems such as low battery power or alarm occur, the energy-saving management ECU will actively send the battery SOC, CCA and U value parameter information to the smart cockpit / instrument and T-Box on the CAN bus for alarm reminders, reminding the user that there is an abnormal problem with the current battery status or power, which needs to be dealt with in time. If the user fails to take effective measures in time, the energy-saving management ECU will forcefully intervene in the power distribution and drive output control through energy-saving instructions, so that the vehicle enters the energy-saving mode and limits the use of high-power electrical equipment or some functions of the vehicle until the energy-saving mode is exited, thereby ensuring a longer service life of the vehicle battery and reducing the economic losses and vehicle operating time cost losses caused by towing and rescue caused by severe battery damage due to irregular electricity use.

[0028] 3. If the user does not take energy-saving intervention measures within the specified time after the first-level warning, or if the user does not take energy-saving intervention measures immediately after the second-level warning is output, the vehicle will be actively controlled to enter the energy-saving mode. This further avoids the battery life being damaged due to the user's subjective or non-subjective neglect or delay in handling the alarm reminder.

[0029] 4. This method not only includes the pop-up alarm in the smart cockpit or instrument screen to remind the user when the vehicle is in normal operation, but also adds a method of actively pushing alarm reminder information to the user's mobile phone APP based on the Internet of Vehicles communication terminal and the Internet of Vehicles cloud platform, which effectively compensates for the alarm reminder needs in situations such as static power consumption of long-term parking of the vehicle resulting in insufficient battery power, excessive power consumption in rest scenarios resulting in insufficient battery power, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Embodiment 1

[0041] Figure 1 The flowchart of the energy-saving control method for a fuel vehicle provided by the present invention according to the preferred embodiment of the present application is shown. For the sake of convenience, only the part related to the present embodiment is shown, which is described in detail as follows:

[0042] The present invention provides a fuel vehicle energy-saving control method, comprising:

[0043] Real-time monitoring of battery parameters;

[0044] The battery parameters are compared and analyzed with the preset values, and warnings of different urgency levels are issued according to different analysis results. The warnings of different urgency levels include at least level one, level two and level three in order of urgency from low to high. The level one and level two warnings are executed in the form of active notifications, and the warnings are canceled after the user takes energy-saving intervention measures. The level three warning is executed in the form of active notifications, and the vehicle is actively controlled to enter an energy-saving mode.

[0045] In one embodiment, when the user does not take energy-saving intervention measures within a specified period of time after the first-level warning is output, or when the user does not immediately take energy-saving intervention measures after the second-level warning is output, the vehicle is actively controlled to enter the energy-saving mode.

[0046] In one embodiment, the battery parameters include the battery remaining power percentage SOC, the cold start current value CCA and the battery terminal voltage value U, and the comparison and analysis of the monitored values ​​with the preset values ​​includes:

[0047] When SOC≥S1, or U≥U1 and CCA≥C1, no warning is triggered;

[0048] When S2≤SOC<S1, or U2≤U<U1 and CCA≥C1, the first level warning is triggered;

[0049] When S3≤SOC<S2 and U3≤U<U2, or C2≤CCA<C1, the second level warning is triggered;

[0050] When SOC≤S3 and U<U3, or CCA<C2, the third-level warning is triggered;

[0051] Among them, S1, S2, S3, U1, U2, U3, C1, and C2 are all preset values, and S3<S2<S1, U3<U2<U1, and C2<C1.

[0052] In one embodiment, the energy-saving intervention measures taken by the user include actively starting the vehicle or shutting down high-power electrical equipment powered by the battery.

[0053] In one embodiment, in the energy-saving mode, the input power of the high-power electrical equipment powered by the battery is cut off.

[0054] In one embodiment, when the vehicle is in the energy-saving mode, if the vehicle enters a starting state, the energy-saving mode is exited.

[0055] In one embodiment, the whole vehicle current is also monitored. When the whole vehicle current is monitored to be less than a preset current value, the intelligent battery sensor IBS stops sending the detected battery parameter message information and enters a dormant state; when the whole vehicle current is monitored to be greater than or equal to the preset current value, the intelligent battery sensor IBS broadcasts the battery parameter message to the vehicle network at a specified period.

[0056] In one embodiment, when the IBS enters the dormant state, the battery parameters are still monitored, and when the battery parameters reach the warning standard, the current battery parameters are sent to the vehicle network.

[0057] In one embodiment, the active notification includes sending a warning message to a vehicle display screen and / or a mobile phone APP, and the warning message is output in the form of text or sound and light.

[0058] Embodiment 2

[0059] The present invention also provides a fuel vehicle energy-saving control system, comprising:

[0060] Acquisition module, used for real-time monitoring of battery parameters;

[0061] The early warning analysis module is used to compare and analyze the battery parameters with the preset values, and to issue early warnings of different urgency levels according to different analysis results. The early warnings of different urgency levels include at least level one, level two and level three in order of urgency from low to high. The level one and level two early warnings are executed in the form of active notifications and cancellation of the early warnings after the user takes energy-saving intervention measures. The level three early warning is executed in the form of active notifications and active control of the vehicle to enter energy-saving mode.

[0062] The acquisition module and the early warning analysis module can be separately set up outside the existing hardware of the vehicle, or can use the existing equipment of the vehicle. In this embodiment, the acquisition module uses an intelligent battery sensor IBS (Intelligent Battery Sensor), and the early warning analysis module uses an energy-saving management ECU.

[0063] like Figure 2 The figure shows the system architecture for implementing the above method based on the intelligent battery sensor IBS and the energy-saving management ECU. The intelligent battery sensor IBS detects the battery remaining power percentage SOC (State of Charge), cold cranking current value CCA (Cold Cranking Ampere) and battery terminal voltage value U and other parameter information of the vehicle in real time under different application scenarios, and sends the detected battery parameter information to the CAN / LIN bus network in the form of a message according to a certain judgment logic. The judgment logic of IBS sending battery parameter message information to the CAN / LIN bus network is as follows:

[0064] 1. IBS monitors the vehicle current parameter value in real time. When the detected static current of the vehicle is less than I (calibrable), IBS stops sending the detected battery parameter message information and enters the dormant state;

[0065] 2. When the static current of the vehicle is detected to be greater than or equal to I (calibrable), the IBS is awakened and sends the detected battery parameter information to the CAN / LIN bus network in a periodic broadcast message;

[0066] 3. When IBS is in sleep mode, it still monitors the battery SOC, SOH, CCA and voltage parameters. When the detected battery parameter values ​​(SOC, CCA and U) trigger the alarm threshold, IBS will be awakened and send several frames of the detected battery parameter information to the CAN / LIN bus to activate the network, report to the Internet of Vehicles cloud platform through T-Box and push alarms to remind users.

[0067] The energy-saving management ECU obtains the battery SOC, CCA and U value information through the vehicle network and determines the battery status:

[0068] 1. When "SOC value ≥ S1 (calibratable)" or "U ≥ U1 (calibratable) and CCA ≥ C1 (calibratable)", the status is judged as "battery is good", and no alarm is triggered at this time;

[0069] 2. When "S2 (calibrable) ≤ SOC value < S1" or "U2 (calibrable) ≤ U < U1 and CCA ≥ C1", the status is judged as "low battery, please charge", and the first-level warning is triggered. After the first-level warning is triggered, the alarm reminder message is output: "Battery power is low, please start the vehicle to charge within T1 (time parameter can be calibrated)", if the user does not take any effective treatment measures within T1 time, the alarm reminder message is output: "Battery power alarm, the vehicle enters energy-saving mode, please start the vehicle to charge immediately";

[0070] 3. When "S3 (calibratable) ≤ SOC value < S2", "U3 (calibratable) ≤ U value < U2" or "C2 (calibratable) ≤ CCA value < C1", the status is judged as "battery power alarm, please charge", and the second-level warning is triggered. After the second-level warning is triggered, the alarm reminder message is output: "Battery power alarm, the vehicle enters energy-saving mode, please start the vehicle and charge immediately";

[0071] 4. When "SOC value ≤ S3", "U<U3" or "CCA<C2", the status is judged as "the battery is seriously low on power, please replace the battery". At this time, the third-level warning is triggered and the alarm reminder message is output: "The battery is seriously low on power, please replace the battery".

[0072] Among them, the alarm reminder information is sent to the smart cockpit or instrument through the CAN bus to pop up an alarm on the screen to remind the user (non-sleeping state), and is sent to the Internet of Vehicles communication terminal (T-Box) through the CAN bus. The T-Box then collects the information and uploads it to the Internet of Vehicles cloud platform. The Internet of Vehicles cloud platform simultaneously pushes the alarm reminder information to the mobile phone APP of the vehicle-side user, prompting him to take necessary processing measures.

[0073] When the third-level warning is triggered, compulsory intervention measures will be adopted directly.

[0074] When a level 1 or level 2 warning is triggered, if for a level 1 warning, after the alarm information is output, the user does not take energy-saving intervention measures within the specified time T1 (e.g., 10 minutes); or for a level 2 warning, after the alarm information is output, the user does not take energy-saving intervention measures immediately (e.g., 10 seconds), then compulsory intervention measures are directly adopted.

[0075] The compulsory intervention measures of this embodiment include:

[0076] The energy-saving management ECU sends energy-saving instructions to the CAN bus network. After receiving the energy-saving instructions, other ECUs on the network (such as smart distribution boxes, chassis modules, etc.) immediately force the cutting of input power of high-power electrical equipment (such as air conditioners, DC-AC, etc.) and ECU actuator drive output (such as lighting control, etc.), so that the whole vehicle enters the energy-saving mode, and pushes the alarm reminder information to the user's mobile phone APP through the Internet of Vehicles cloud platform. Figure 3 As shown in the figure, after the vehicle enters the energy-saving mode, the vehicle's high-power electrical equipment or some functions cannot be used normally until the vehicle exits the energy-saving mode to ensure that the vehicle is at a low power consumption level to extend the battery life and to ensure that the vehicle has enough power to start normally. When the vehicle starts, the energy-saving management ECU immediately exits the energy-saving mode and returns to the normal mode state, and the vehicle function operations return to normal.

[0077] Among them, IBS adopts the CAN / LIN bus solution, as a subnet ECU directly connected to the energy-saving management ECU, and IBS is powered by normal electricity, supporting the detection and collection of parameter information such as the SOC value, CCA value and U value of the vehicle battery in all application scenarios of the vehicle. And when the IBS is in a dormant state, if it detects that the battery of the vehicle is low or an alarm is issued, the IBS will immediately wake up and send the detected battery parameter information to the energy-saving management ECU. At the same time, IBS (including the scenario where IBS is in a dormant state) supports users to actively issue query commands in real time through the Internet of Vehicles cloud platform or mobile phone APP to query the current status of the battery (including SOC, CCA and U value).

[0078] The vehicle usage scenarios in this method mainly include:

[0079] 1. Sleep scenario: The ignition lock is OFF and the main power switch is turned off. The vehicle is locked and the vehicle network has entered sleep mode.

[0080] 2. Rest scene - the ignition lock is OFF and the main power switch is on. The vehicle only supports some functions, such as parking air conditioning, indoor and outdoor lights off, window lifting, etc.

[0081] 3. Entertainment scene - the ignition lock is in ACC gear and the main power switch is on. In addition to the functions supported by the rest scene, it also supports functions such as audio and video entertainment, DCAC, cigarette lighter, etc.

[0082] 4. Working scenario (engine not started) - ignition lock ON and main power switch turned on. Except for the related function operations restricted because the engine is not started, other functions can be used normally.

[0083] 5. Starting scenario (engine starting) - ignition lock ON and main power switch turned on. Except for the related function operations restricted by engine starting, other functions can be used normally.

[0084] It should be understood that the specific order or hierarchy of steps in the disclosed process is an example of an exemplary method.
