Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a vehicle control method, device, vehicle, and storage medium. Background Technology

[0002] When a vehicle is left parked in low temperatures for an extended period, the 12V battery is prone to depletion. Due to thermal expansion and contraction, tire pressure decreases, increasing the contact area between the tires and the ground, thus increasing steering resistance. Additionally, low temperatures increase the damping effect of grease in the ball joints of suspension components such as upper and lower control arms, stabilizer bars, and tie rods, further restricting their movement and increasing steering resistance. Furthermore, the higher viscosity and reduced flow of automatic transmission fluid at low temperatures increases the workload on the transmission solenoids during gear shifts. When the 12V battery is depleted, if the driver performs driving maneuvers such as shifting gears (drive, reverse, or maneuvering) after starting the engine, the engine consumes battery power, and the increased steering and transmission solenoid loads in low temperatures, coupled with the automatic start of the multimedia system and other electrical components, the overall electrical load is high. This can easily lead to issues such as momentary screen blackouts and music stuttering, negatively impacting the driving experience. Summary of the Invention

[0030] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0031] The vehicle control method, apparatus, vehicle, and storage medium of this application are described below with reference to the accompanying drawings. Addressing the issue mentioned in the background art where prolonged parking in low-temperature environments leads to 12V battery depletion, causing momentary blackouts and music stuttering on the multimedia screen when the driver performs driving operations such as shifting forward and reverse gears or turning the steering wheel after starting the engine, this application provides a vehicle control method. In this method, when the vehicle meets preset charging conditions based on the current SOC, current battery voltage, pressure of the two front tires, and current automatic transmission oil temperature, an engine start request is sent to a preset mobile terminal. If a confirmation command based on the engine start request is received, the engine operating speed and generator duty cycle are determined based on the current SOC and current battery voltage, and the engine is started to charge the vehicle's battery according to the operating speed and generator duty cycle. This solves the problem of the multimedia screen momentarily going black and music stuttering when the 12V battery is depleted due to prolonged parking in low-temperature environments, and when the driver performs driving operations such as shifting forward and reverse gears and turning the steering wheel after starting the vehicle, thus improving the driving experience.

[0032] Specifically, Figure 1 This is a schematic flowchart of a vehicle control method provided in an embodiment of this application.

[0033] like Figure 1 As shown, the vehicle control method includes the following steps:

[0034] In step S101, the current SOC and current voltage of the vehicle's battery, the pressure of the two front tires, and the current automatic transmission fluid temperature are obtained.

[0035] Optionally, in some embodiments, after obtaining the vehicle's current battery SOC and current battery voltage, the pressures of the two front tires, and the current automatic transmission fluid temperature, the method further includes: determining whether the current battery SOC is lower than a first preset charge level, or whether the current battery voltage is lower than a first preset voltage; if the current battery SOC is lower than the first preset charge level, or the current battery voltage is lower than the first preset voltage, then the vehicle is determined to meet preset charging conditions; otherwise, if the current battery SOC is lower than a second preset charge level, or the current battery voltage is lower than the second preset voltage, then the vehicle is determined to meet preset charging conditions, wherein the second preset voltage is higher than the first preset voltage, and the second preset charge level is higher than the first preset charge level.

[0036] Among them, the first preset power A SOC For example, it can be 65%, the first preset voltage AVot For example, it can be 11.5V, with a preset tire pressure A. Pre For example, it can be 2 bar, with a preset oil temperature A. Tem For example, it can be -5°C, and the second preset power B SOC For example, it can be 85%, the second preset voltage B Vot For example, it can be 12.5V.

[0037] Specifically, such as Figure 2 As shown, when the vehicle's battery current SOC is lower than the first preset charge level A... SOC Or the current battery voltage is lower than the first preset voltage A Vot When the engine is started, it indicates that the 12V battery has a very low charge. In this case, if the driver performs driving operations such as shifting forward or reverse gears or turning the steering wheel after starting the engine, the multimedia screen may go black momentarily and the music may stutter, affecting the driving experience. Therefore, the vehicle remote start controller determines that the engine needs to be started to charge the 12V battery.

[0038] The vehicle remote start controller is the controller in the vehicle used for remotely controlling engine start. It, together with the vehicle remote start control application on the driver's mobile phone, constitutes the vehicle remote start control system. The vehicle remote start controller and the vehicle remote start control application on the driver's mobile phone communicate and interact via wireless communication technology, which can be similar to mobile phone communication and signal transmission. The Body Control Module (BCM) constantly monitors the vehicle's current battery SOC and current battery voltage, and sends this information to the vehicle remote start controller and the Engine Control Unit (ECU) via the Controller Area Network (CAN) bus.

[0039] Furthermore, when the current SOC of the battery is not lower than the first preset capacity and the current voltage of the battery is not lower than the first preset voltage, when the current SOC of the battery is lower than the second preset capacity B... SOC Or the current battery voltage is lower than the second preset voltage B. Vot If at least one front tire pressure is lower than the preset tire pressure A Pre Or the current automatic transmission fluid temperature is lower than the preset fluid temperature A. Tem If the vehicle's remote start controller determines that the engine needs to be started to charge the 12V battery, then the vehicle meets the preset charging conditions. Specifically, the front tire pressure is measured by the tire pressure monitoring sensor and sent to the BCM, which then transmits it to the vehicle's remote start controller via the CAN bus. If the front tire pressure is lower than the preset tire pressure A...Pre This indicates that the front tire pressure is low, resulting in greater steering resistance. The automatic transmission fluid temperature is measured by a fluid temperature sensor and sent to the Transmission Control Unit (TCU). The TCU then transmits this information to the vehicle's remote start controller via the CAN bus. The automatic transmission fluid temperature is below a preset temperature A. Tem This indicates that the automatic transmission oil temperature is low, and it also indicates that the vehicle has been placed in a low-temperature environment for a long time. This further indicates that the grease in the ball joints of the upper and lower control arms, stabilizer bars, and tie rods of the vehicle suspension has a greater damping effect on the ball joints. Under this condition, the workload of the transmission solenoid valve and the vehicle steering resistance are both large, and the vehicle remote start controller determines that the engine needs to be started to charge the 12V battery.

[0040] Therefore, if the current SOC of the battery is lower than the first preset capacity A SOC Or the current battery voltage is lower than the first preset voltage A Vot This indicates that the 12V battery has a very low charge, and the vehicle's remote start controller determines that the engine needs to be started to charge the 12V battery. Alternatively, if the battery's current SOC is not lower than a first preset charge level A... SOC And the current battery voltage is not lower than the first preset voltage A Vot In the case where the current SOC of the battery is lower than the second preset capacity B SOC Or the current battery voltage is lower than the second preset voltage B. Vot If at least one front tire pressure is lower than the preset tire pressure A Pre Or the current automatic transmission fluid temperature is lower than the preset fluid temperature A Tem If the vehicle's steering load or transmission workload is too high, and the driver performs driving operations such as shifting forward or reverse gears or turning the steering wheel after starting the engine, the multimedia screen may momentarily go black and the music may stutter, affecting the driving experience. The vehicle's remote start controller determines that the engine needs to be started to charge the 12V battery, meaning the vehicle meets the preset charging conditions.

[0041] Furthermore, in some embodiments, after obtaining the vehicle's current battery SOC and current battery voltage, the pressure of the two front tires, and the current automatic transmission fluid temperature, the method further includes: if the current battery SOC is not lower than a first preset charge level and the current battery voltage is not lower than a first preset voltage, then determining whether the current battery SOC is lower than a second preset charge level or whether the current battery voltage is lower than a second preset voltage; if the current battery SOC is not lower than a second preset charge level and the current battery voltage is not lower than a second preset voltage, then determining that the vehicle does not meet the preset charging conditions; if the current battery SOC is lower than a second preset charge level or the current battery voltage is lower than a second preset voltage, then determining whether the pressure of the two front tires is not lower than a preset tire pressure and whether the current automatic transmission fluid temperature is not lower than a preset fluid temperature; if the pressure of the two front tires is not lower than a preset tire pressure and the current automatic transmission fluid temperature is not lower than a preset fluid temperature, then determining that the vehicle does not meet the preset charging conditions.

[0042] It should be understood that when the vehicle's battery current SOC is higher than the second preset charge level B... SOC And the current battery voltage is higher than the second preset voltage B. Vot When the vehicle's remote start controller determines that it is not necessary to start the engine to charge the 12V battery, it indicates that the 12V battery has a high charge level. Even in low-temperature environments, when the driver performs driving operations such as shifting forward and reverse gears and turning the steering wheel after starting the engine, it is not likely to cause the multimedia screen to go black momentarily or the music to stutter. This will not affect the driving experience. Therefore, it is not necessary to charge the battery, meaning the vehicle does not meet the preset charging conditions.

[0043] When the current SOC of the battery is not lower than the first preset charge level and the current voltage of the battery is not lower than the first preset voltage level, if the current SOC of the battery is lower than the second preset charge level or the current voltage of the battery is lower than the second preset voltage level, it indicates that the charge level of the 12V battery is neither very low nor very high, but at a moderate level. In this case, if the front tire pressure is not lower than the preset tire pressure A, Pre Or the automatic transmission fluid temperature is lower than the preset fluid temperature A Tem If the vehicle's steering load and transmission workload are not too high, and the driver performs driving operations such as shifting forward and reverse gears and turning the steering wheel after starting the engine, the multimedia screen is unlikely to go black momentarily or the music will stutter. This will not affect the driving experience. The vehicle's remote start controller determines that it is not necessary to start the engine to charge the 12V battery, meaning that the vehicle does not meet the preset charging conditions.

[0044] It should be noted that the vehicle remote start controller constantly monitors the vehicle's current battery SOC and voltage, the pressure of both front tires, and the current automatic transmission fluid temperature to determine whether the engine needs to be started to charge the 12V battery. Furthermore, the second preset voltage B mentioned above... Vot Higher than the first preset voltage A Vot Second preset power B SOC Higher than the first preset power A SOC And the first preset power A SOC First preset voltage A Vot Second preset power level B SOC Second preset voltage B Vot Preset tire pressure A Pre and preset oil temperature A Tem The value can be set according to the specific performance of the actual vehicle multimedia screen's instantaneous black screen and music stuttering issues. The setting value is only given as an example in this application embodiment and is not intended to be limiting.

[0045] In step S102, when the vehicle meets the preset charging conditions based on the current SOC and current voltage of the battery, the pressure of the two front tires and the current automatic transmission oil temperature, an engine start request is sent to the preset mobile terminal.

[0046] Optionally, in some embodiments, after sending the engine start request to the preset mobile terminal, the process includes: determining whether a rejection instruction sent by the mobile terminal based on the engine start request is received, or determining whether a confirmation instruction from the mobile terminal is not received within a preset time period; if a rejection instruction is received, then the engine start request is sent to the preset mobile terminal according to a preset period t2; if no confirmation instruction is received within a preset time period t1, then the engine start request is immediately sent to the preset mobile terminal, and if the number of times the request is sent is greater than or equal to a preset number, it is determined that the driver refuses to start the engine.

[0047] For example, the preset duration t1 and preset period t2 can both be 30 minutes, and the preset number of times n can be 3. However, n should not be too large to avoid causing annoyance and complaints from drivers.

[0048] Specifically, such as Figure 3As shown, if it is determined that the engine needs to be started to charge the 12V battery, an engine start request is sent wirelessly to the vehicle remote start control application (APP) on the driver's mobile phone. A notification message appears on the mobile phone indicating that the engine is being started to charge the 12V battery, and the driver is prompted to confirm via phone vibration or a notification sound. Furthermore, if the vehicle remote start controller does not receive a signal from the vehicle remote start control application (allowing or denying engine start) after a preset time t1 after sending the engine start request, it indicates that the driver has not responded to the engine start request. In this case, the vehicle remote start controller will send the engine start request again to the vehicle remote start control application on the driver's mobile phone.

[0049] If the driver refuses to start the engine after receiving a vibration or notification sound from the vehicle remote start control application on their mobile phone, and sends this refusal signal back to the vehicle remote start controller from the vehicle remote start control application on their mobile phone, it means that the driver may be refusing to start the engine for their own reasons. In this case, the vehicle remote start controller will send an engine start request to the vehicle remote start control application on the driver's mobile phone again after a preset interval t2.

[0050] This process continues until the number of times the vehicle remote start controller sends an engine start request (i) to the driver's mobile remote start control application (APP) reaches or exceeds the preset number (n). If the vehicle remote start controller still does not receive a signal from the driver's mobile remote start control application (APP) indicating whether the engine can be started or not, or if the driver refuses to start the engine and sends this refusal signal back to the vehicle remote start controller from the mobile remote start control application (APP), then the vehicle remote start controller will no longer send an engine start request to the driver's mobile remote start control application (APP), and the vehicle remote start controller will determine that the driver has refused to start the engine. Here, the initial value of i is 0.

[0051] If the driver allows the engine to start after receiving a vibration or notification sound from the vehicle remote start control application on their mobile phone, and this permission signal is sent back from the vehicle remote start controller to the vehicle remote start controller, then it means that the driver has given permission to start the engine.

[0052] It is understandable that if the vehicle remote start controller determines that it does not need to start the engine to charge the 12V battery, it will not send an engine start request to the vehicle remote start control application APP on the driver's mobile phone, and there is no need for interactive confirmation with the driver to start the engine.

[0053] In step S103, if a determination command based on the engine start request feedback is received, the engine operating speed and generator duty cycle are determined based on the current battery SOC and current battery voltage, and the engine is started to charge the vehicle's battery according to the operating speed and generator duty cycle.

[0054] Specifically, if it is determined that the engine needs to be started to charge the 12V battery, the vehicle remote start controller will interact with the ECU to control the engine to start and charge the 12V battery after receiving a start-allowed signal from the vehicle remote start control application on the driver's mobile phone. If the result of the interaction between the vehicle remote start control system and the driver is a refusal to start the engine, the vehicle remote start controller will not interact with the ECU to control the engine to charge the 12V battery.

[0055] Furthermore, based on the current SOC and voltage of the battery, the engine operating speed and generator duty cycle are determined, and it is decided whether to shut down the engine. Specifically: after the vehicle remote start controller interacts with the ECU to start the engine to charge the 12V battery, the ECU controls the engine operating speed n based on the vehicle's current SOC and current battery voltage. E The generator's power generation duty cycle PWM is shown in Table 1 and Table 2.

[0056] Table 1 Engine operating speed n E

[0057]

[0058]

[0059] Table 2 Generator Duty Cycle (PWM)

[0060]

[0061] Among them, the engine operating speed n in Table 1 E The specific PWM duty cycle of the generator in Table 2 can be calibrated and set according to the actual charging effect of the 12V battery in the vehicle. Generally speaking, the engine operating speed n Eij (i = 1, 2, ..., 5; j = 1, 2, ..., 4) and the generator's power generation duty cycle PWM ijThe setting principle for (i = 1, 2, ..., 5; j = 1, 2, ..., 4) is: under the same battery voltage, the lower the battery SOC, the higher the engine operating speed n. Eij (i = 1, 2, ..., 5; j = 1, 2, ..., 4) should be as high as possible, and the generator's power generation duty cycle PWM should be as high as possible. ij (i = 1, 2, ..., 5; j = 1, 2, ..., 4) should be as large as possible to improve the charging efficiency of the 12V battery; correspondingly, the higher the battery SOC, the higher the engine operating speed n. Eij (i = 1, 2, ..., 5; j = 1, 2, ..., 4) can be reduced accordingly, and the generator's duty cycle PWM can be adjusted. ij (i = 1, 2, ..., 5; j = 1, 2, ..., 4) can be reduced accordingly to improve vehicle fuel economy. At the same battery SOC, the lower the battery voltage, the higher the engine operating speed n. Eij (i = 1, 2, ..., 5; j = 1, 2, ..., 4) should be as high as possible, and the generator's power generation duty cycle PWM should be as high as possible. ij (i = 1, 2, ..., 5; j = 1, 2, ..., 4) should be as large as possible to improve the charging efficiency of the 12V battery; correspondingly, the higher the battery voltage, the higher the engine operating speed n. Eij (i = 1, 2, ..., 5; j = 1, 2, ..., 4) can be reduced accordingly, and the generator's duty cycle PWM can be adjusted. ij (i = 1, 2, ..., 5; j = 1, 2, ..., 4) can be reduced accordingly to improve vehicle fuel economy. The generator's duty cycle PWM... ij The range of (i = 1, 2, ..., 5; j = 1, 2, ..., 4) is 0 to 1.

[0062] Optionally, in some embodiments, when starting the engine to charge the vehicle's battery based on the operating speed and generator duty cycle, the process includes: determining a first target operating speed of the engine based on the current state of charge (SOC) and current battery voltage, and determining whether the engine has entered a warm-up mode; if the engine has entered a warm-up mode, then taking the larger of the first target operating speed and the second target operating speed in the warm-up mode as the third target operating speed of the engine; otherwise, taking the first target operating speed as the third target operating speed of the engine; and taking the third target operating speed of the engine as the final target control speed for engine operation to control engine operation.

[0063] This embodiment of the application takes into account that after a vehicle has been parked for a long time, the engine will generally enter a warm-up mode when started. Therefore, under this condition, the ECU calculates the first target operating speed n based on the vehicle's current battery SOC and current battery voltage. EThen it is also necessary to check the engine's second target operating speed n in warm-up mode. EWT The maximum value is compared and taken as the final target control speed n for engine operation. F That is, the operating speed of the third target, specifically as follows: Figure 4 As shown, the second target operating speed n of the engine in warm-up mode is... EWT The target engine speed value is pre-calibrated in the ECU and used to control the engine operation in warm-up mode, so as to achieve rapid engine warm-up and rapid ignition of the three-way catalytic converter, which is beneficial to the vehicle's fuel consumption and emissions.

[0064] Optionally, in some embodiments, after starting the engine to charge the vehicle's battery according to the operating speed and power generation duty cycle, the method includes: detecting the current state of charge (SOC) and current voltage of the battery; if the current SOC of the battery is not lower than a third preset charge level and the current voltage of the battery is not lower than a third preset voltage, then controlling the engine to shut off, wherein the third preset charge level is higher than a second preset charge level and the third preset voltage is higher than the second preset voltage.

[0065] Among them, the third preset power C SOC For example, it can be 90%, the third preset voltage C Vot For example, it can be 13.5V, with a third preset power C. SOC and the third preset voltage C Vot The value can be set according to the specific performance of the actual vehicle's 12V battery charging efficiency, discharge loss, and multimedia screen momentary blackout and music stuttering issues. The setting value is only provided as an example in this application embodiment and is not limited thereto. Among them, the third preset power C SOC Higher than the second preset power level B SOC The third preset voltage C Vot Higher than the second preset voltage B Vot .

[0066] It should be understood that when the vehicle remote start controller detects that the current SOC of the battery is not lower than the third preset charge level C... SOC And the current battery voltage is not lower than the third preset voltage C. Vot At this time, the vehicle's remote start controller determines that the 12V battery has a relatively high charge and does not need to be recharged. Therefore, it interacts with the ECU to control the engine to shut off, thereby saving fuel consumption. The third preset battery charge C... SOC Higher than the second preset power level B SOC The third preset voltage C Vot Higher than the second preset voltage B Vot To avoid the front tire pressure of the vehicle falling below the preset tire pressure A Pre Or the current automatic transmission fluid temperature is lower than the preset fluid temperature A TemIn this case, the vehicle remote start controller will start the vehicle and charge it until the current SOC of the battery is higher than the third preset charge level C. SOC And the current voltage is higher than the third preset voltage C. Vot The system controls the engine to stop for a period of time, and then restarts the vehicle to charge the 12V battery due to the further depletion of the battery power, and then stops the engine again. This avoids the frequent start-stop cycles of the engine to charge the vehicle's 12V battery, thus ensuring the lifespan of the vehicle's starter motor and achieving intelligent vehicle control.

[0067] To enable those skilled in the art to further understand the vehicle control method of the embodiments of this application, the following detailed description is provided in conjunction with specific embodiments, such as... Figure 5 As shown.

[0068] In S501, based on the vehicle's current SOC and current battery voltage, the pressure of the two front tires and the current automatic transmission fluid temperature, it is determined whether the engine needs to be started to charge the 12V battery.

[0069] In S502, if it is determined that the engine needs to be started to charge the 12V battery, the driver will be contacted for confirmation through the vehicle remote start control system.

[0070] In S503, if the result of the interaction between the vehicle remote start control system and the driver is that the engine can be started, then the vehicle is controlled to start the engine.

[0071] In S504, based on the vehicle's current SOC and current battery voltage, the engine's operating speed and the generator's duty cycle are controlled, and it is determined whether to shut down the engine.

[0072] According to the vehicle control method proposed in this application, when the vehicle meets the preset charging conditions based on the current SOC of the battery, the current voltage of the battery, the pressure of the two front tires, and the current automatic transmission oil temperature, an engine start request is sent to a preset mobile terminal. If a confirmation command based on the engine start request feedback is received, the engine operating speed and the generator duty cycle are determined based on the current SOC and current voltage of the battery, and the engine is started to charge the vehicle's battery according to the operating speed and generator duty cycle. This solves the problem of the 12V battery being depleted after the vehicle has been parked in a low-temperature environment for a long time, which can easily cause the multimedia screen to momentarily go black and the music to stutter when the driver performs driving operations such as shifting forward and reverse gears and turning the steering wheel after starting the engine, thus improving the driving experience.

[0078] Optionally, in some embodiments, after acquiring the current SOC and current voltage of the vehicle's battery, the pressure of the two front tires, and the current automatic transmission fluid temperature, the acquisition module 100 is further configured to: if the current SOC of the battery is not lower than a first preset charge level and the current voltage of the battery is not lower than a first preset voltage, then determine whether the current SOC of the battery is lower than a second preset charge level or whether the current voltage of the battery is lower than a second preset voltage; if the current SOC of the battery is not lower than a second preset charge level and the current voltage of the battery is not lower than a second preset voltage, then determine that the vehicle does not meet the preset charging conditions; if the current SOC of the battery is lower than a second preset charge level or the current voltage of the battery is lower than a second preset voltage, then determine whether the pressure of the two front tires is not lower than a preset tire pressure and whether the current automatic transmission fluid temperature is not lower than a preset fluid temperature; if the pressure of the two front tires is not lower than a preset tire pressure and the current automatic transmission fluid temperature is not lower than a preset fluid temperature, then determine that the vehicle does not meet the preset charging conditions.

[0079] Optionally, in some embodiments, after sending the engine start request to the preset mobile terminal, the sending module 200 is further configured to: determine whether a rejection instruction sent by the mobile terminal based on the engine start request is received, or determine whether a confirmation instruction from the mobile terminal is not received within a preset time period; if a rejection instruction is received, then the engine start request is sent to the preset mobile terminal according to a preset cycle; if a confirmation instruction is not received within the preset time period, then the engine start request is immediately sent to the preset mobile terminal, and if the number of times the request is sent is greater than or equal to a preset number, it is determined that the driver refuses to start the engine.

[0082] It should be noted that the foregoing explanation of the vehicle control method embodiment also applies to the vehicle control device of this embodiment, and will not be repeated here.

[0083] According to the vehicle control device proposed in this application embodiment, when the vehicle meets the preset charging conditions based on the current SOC of the battery, the current voltage of the battery, the pressure of the two front tires, and the current automatic transmission oil temperature, an engine start request is sent to a preset mobile terminal.
