[0023] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0024] This application provides a method for controlling the battery level of a vehicle. Please refer to the following embodiments. Figure 1 The diagram illustrates the implementation environment of the method provided in this application embodiment. This implementation environment may include: EMS (Engine Management System) 11, HCU (Hybrid Control Unit) 12, BMS (Battery Management System) 13, and HMI (Human Machine Interface) 14.
[0025] Generally, the HCU12 reads the SOC of the vehicle's power battery from the BMS13, and obtains the vehicle's power control mode and the set target SOC from the HMI14. These two parameters are set by the user via touch on the HMI14. The HMI14 determines the vehicle's engine operating status based on the power battery's SOC, the set target SOC, the power control mode, the power battery's default target SOC, and the vehicle's speed. The HCU12 controls the engine's operating status through the EMS11. The HMI14 displays the vehicle's power battery SOC, power control mode, and engine operating status. The EMS11, HCU12, BMS13, and HMI14 establish a communication connection via a bus.
[0026] Based on the above Figure 1 The implementation environment shown in this application provides a vehicle battery control method, such as... Figure 2 As shown, taking the application of this method to HCU as an example, the method includes steps 201-203.
[0027] In step 201, the SOC of the vehicle's power battery is obtained. The SOC of the power battery is the percentage of the remaining power battery capacity relative to the total power capacity.
[0028] In one possible implementation, the State of Charge (SOC) of the power battery is the percentage of its remaining charge relative to the total charge. Obtaining the SOC of the vehicle's power battery includes: the HCU reading the SOC of the vehicle's power battery from the BMS via a bus. The BMS is located on the vehicle and monitors the battery's SOC, voltage, and temperature in real time. Exemplarily, the bus can be a CAN (Controller Area Network) bus.
[0029] In step 202, the vehicle's power control mode is obtained. The power control mode includes default mode, long-distance driving mode, power saving mode, or charging mode.
[0030] For example, a user can select a vehicle's battery control mode on the vehicle's HMI, where the battery control mode includes a default mode, a long-distance driving mode, a power-saving mode, or a charging mode. Optionally, after the user selects a battery control mode, obtaining the vehicle's battery control mode includes: the HCU obtaining the vehicle's battery control mode from the HMI via the CAN bus.
[0031] In one possible implementation, after the vehicle is powered on for the first time, the vehicle's power control mode is the default mode before the HCU receives the user-selected power control mode.
[0032] In step 203, the operating state of the vehicle's engine is determined based on the SOC of the power battery and the power control mode, so that the engine can operate according to the operating state. The operating state of the engine includes the engine charging or the engine stopping charging. The initial operating state of the engine is the engine charging.
[0033] Optionally, after determining the SOC and charge control mode of the power battery, the operating state of the vehicle's engine is determined based on the SOC and charge control mode of the power battery. The operating state of the engine includes whether the engine is charging or not charging. Before determining the operating state of the vehicle's engine based on the SOC and charge control mode of the power battery, the default initial operating state of the engine is that the engine is not charging.
[0034] In one possible implementation, in response to the power control mode being the default mode and the SOC of the power battery being less than or equal to a first reference percentage and greater than a second reference percentage, the vehicle's driving speed is obtained, where the first reference percentage is the default target SOC of the power battery; the engine's operating state is controlled according to the vehicle's driving speed; in response to the engine's operating state being to recharge the engine and the SOC of the power battery being greater than a third reference percentage, the engine's operating state is controlled to switch to engine stop recharging, where the third reference percentage is greater than the first reference percentage.
[0035] For example, when the vehicle's battery control mode is in default mode, if the SOC of the power battery is greater than a first reference percentage, the engine remains operational but stops charging, and the vehicle is driven by the power battery's charge. The vehicle is driven by the engine; if the engine stops driving the vehicle, the vehicle is in pure electric mode. Here, the first reference percentage is the default target SOC of the power battery. For example, the SOC that generally ensures the vehicle will not run out of power can be set as the default target SOC of the power battery; for example, the first reference percentage can be 20%, or it can be changed according to actual needs.
[0036] Optionally, when the vehicle's battery control mode is in the default mode, if the SOC of the power battery is less than or equal to a first reference percentage and greater than a second reference percentage, the vehicle's driving speed is obtained, including: the HCU obtaining the vehicle's speed from the vehicle's central control system via the CAN bus. The second reference percentage is less than the first reference percentage; for example, the second reference percentage can be 15%, or it can be changed according to actual needs.
[0037] For example, after obtaining the vehicle's driving speed, controlling the engine's operating state according to the vehicle's driving speed includes: in response to the vehicle's driving speed being greater than a first reference speed, controlling the engine's operating state to provide additional power to the engine.
[0038] In one possible implementation, if the vehicle's speed is greater than a first reference speed, the HCU controls the EMS to start the engine to recharge the battery, and the engine's operating state switches to engine-assisted recharging. If the vehicle's speed is less than or equal to the first reference speed, the engine remains in a state where recharging is stopped, and the vehicle is driven by the battery's charge. The system acquires the engine-driven vehicle status; if the engine stops driving the vehicle, the vehicle operates in pure electric mode. For example, the first reference speed can be 30 km / h, but it can be adjusted according to actual conditions.
[0039] For example, in response to the engine's operating state of recharging the engine and the SOC of the power battery being greater than a third reference percentage, controlling the engine's operating state to switch to engine stop recharging includes: after the engine starts recharging the power battery, if the SOC of the power battery is greater than the third reference percentage, the HCU controls the EMS to stop the engine from recharging the power battery, and the engine's operating state switches to engine stop recharging. Optionally, the third reference percentage can be the first reference percentage plus 5%, and the third reference percentage can also be adjusted according to actual needs, but it must be ensured that the third reference percentage is greater than the first reference percentage.
[0040] In default mode, the vehicle is driven by the battery's charge when the battery's SOC is greater than a first reference percentage, less than or equal to the first reference percentage but greater than a second reference percentage, and the vehicle's speed is less than a first reference speed, or when the SOC is greater than a third reference percentage after the engine starts. This allows the vehicle to operate in pure electric mode and achieve a longer pure electric range. This is typically suitable for urban driving conditions.
[0041] In one possible implementation, in response to the power control mode being a power-saving mode, the target SOC corresponding to the power-saving mode is obtained; in response to the SOC of the power battery being less than or equal to the target SOC corresponding to the power-saving mode and greater than a first reference percentage, the vehicle's driving speed is obtained; the engine's operating state is controlled according to the vehicle's driving speed; in response to the SOC of the power battery being less than the first reference percentage, the engine's operating state is controlled to perform engine recharging; in response to the engine's operating state performing engine recharging and the SOC of the power battery being greater than a third reference percentage, the engine's operating state is controlled to switch to engine stop recharging, where the third reference percentage is greater than the first reference percentage.
[0042] For example, when the power control mode is in power-saving mode, the user can set the target SOC corresponding to the power-saving mode on the vehicle's HMI. After the user sets the target SOC, the HCU obtains the target SOC corresponding to the power-saving mode from the HMI via the CAN bus. For example, the target SOC corresponding to the power-saving mode can be in the range of 30% to 70%.
[0043] If the SOC of the power battery is less than or equal to the target SOC corresponding to the power saving mode and greater than the first reference percentage, the vehicle's driving speed is obtained, including: the HCU obtains the vehicle's speed from the vehicle's central control system via the CAN bus. For example, after obtaining the vehicle's driving speed, the engine's operating state is controlled according to the vehicle's driving speed, including: in response to the vehicle's driving speed being greater than the second reference speed, controlling the engine's operating state to replenish the engine's power.
[0044] Optionally, if the vehicle speed is greater than the second reference speed, the HCU controls the EMS to start the engine to recharge the power battery, and the engine's operating state switches to engine-assisted recharging, while the EMS controls the engine to operate within the fuel-efficient range. If the vehicle speed is less than or equal to the second reference speed, the engine remains in its recharging state, and the vehicle is driven by the power battery's charge. If the engine stops driving the vehicle, the vehicle operates in pure electric mode. For example, the second reference speed can be 80 km / h, but it can also be adjusted according to actual conditions.
[0045] For example, the EMS controls the engine to replenish power within the economical and fuel-saving range, including but not limited to, the EMS adjusting the engine torque to an economical and fuel-saving torque range, wherein the fuel-saving torque range can be determined experimentally.
[0046] In one possible implementation, in response to the SOC of the power battery being less than a first reference percentage, the engine's operating state is controlled to recharge the engine, including: if the SOC of the power battery is less than the first reference percentage, the HCU controls the EMS to start the engine to recharge the power battery, and the engine's operating state is switched to recharge the engine.
[0047] For example, in response to the engine's operating state of replenishing power to the engine and the SOC of the power battery being greater than a third reference percentage, the engine's operating state is controlled to switch to engine stop replenishing power, including: after the engine starts replenishing power to the power battery, if the SOC of the power battery is greater than the third reference percentage, the HCU controls the EMS to stop the engine from replenishing power to the power battery, and the engine's operating state is switched to engine stop replenishing power.
[0048] Optionally, in response to the battery control mode being a long-distance driving mode, the distance from the vehicle's current location to the destination, the congestion situation of the vehicle's current driving segment, and the congestion situation of the vehicle's next driving segment are obtained; based on the distance from the vehicle's current location to the destination, the congestion situation of the vehicle's current driving segment, and the congestion situation of the vehicle's next driving segment, a target SOC corresponding to the long-distance driving mode is determined, which includes a first target SOC and a second target SOC; in response to the power battery's SOC being less than or equal to the first target SOC, the engine's operating state is controlled to allow the engine to replenish power; in response to the power battery's SOC being greater than the second target SOC and the engine's operating state being allowed to replenish power, the engine's operating state is controlled to switch to allow the engine to stop replenishing power.
[0049] For example, when the battery control mode is set to long-distance driving mode, the user can set a destination on the vehicle's HMI. The HCU obtains the destination from the HMI via the CAN bus and then sends the destination to the navigation system via the CAN bus. Based on the destination, the system determines the distance from the vehicle's current location to the destination, the congestion situation of the current driving segment, and the congestion situation of the next driving segment. The navigation system, installed in the vehicle, can collect data on road location and congestion conditions, and calculate the road distances between locations.
[0050] In one possible implementation, after determining the distance from the vehicle's current location to the destination, the congestion situation of the current road segment, and the congestion situation of the next road segment, a target SOC corresponding to the long-distance driving mode is determined based on these factors. This includes: classifying the distance from the vehicle's current location to the destination, the congestion situation of the current road segment, and the congestion situation of the next road segment; and matching different target SOCs for different long-distance driving modes based on different levels of these factors. The target SOC for the long-distance driving mode includes a first target SOC and a second target SOC. The first target SOC indicates the threshold at which the engine begins to recharge the power battery, and the second target SOC indicates the threshold at which the engine stops recharging the power battery.
[0051] Optionally, in response to the SOC of the power battery being less than or equal to a first target SOC, the operating state of the engine is controlled to recharge the engine, including: if the SOC of the power battery is less than or equal to the first target SOC, the HCU controls the EMS to start the engine to recharge the power battery, and the operating state of the engine is switched to recharge the engine.
[0052] For example, in response to the SOC of the power battery being greater than the second target SOC and the engine operating state being to recharge the battery, the engine operating state is switched to the state of stopping the recharge, including: after the engine starts to recharge the power battery, if the SOC of the power battery is greater than the second target SOC, the HCU controls the EMS to stop the engine from recharging the power battery, and the engine operating state is switched to the state of stopping the recharge.
[0053] By combining the distance from the vehicle's current location to the destination, the congestion situation of the current driving segment, and the congestion situation of the next driving segment in the long-distance driving mode, the SOC at which the engine starts charging and the SOC at which the engine stops charging are selected for long-distance driving, ensuring that the SOC of the power battery can guarantee that the vehicle can complete long-distance driving while ensuring fuel economy.
[0054] In one possible implementation, in response to the power control mode being in charging mode and the vehicle's memory switch being turned on, the system controls the vehicle to store the target SOC corresponding to the charging mode before each power outage; reads the target SOC corresponding to the charging mode stored before the last power outage; in response to the power battery's SOC being less than or equal to the target SOC corresponding to the charging mode, the system controls the engine's operating state to perform engine recharging; in response to the power battery's SOC being greater than a third reference percentage and the engine's operating state being engine recharging, the system controls the engine's operating state to switch to engine stop recharging.
[0055] For example, when the power control mode is in charging mode and the vehicle's memory switch is on, the HCU stores the target SOC corresponding to the charging mode before each power-off. When the vehicle is powered on again, the vehicle's power control mode is set to charging mode, and the target SOC corresponding to the charging mode stored before the previous power-off is read. The vehicle's memory switch is located on the vehicle and is used to enable the storage of the target SOC corresponding to the charging mode.
[0056] Optionally, in response to the SOC of the power battery being less than or equal to the target SOC corresponding to the charging mode, the engine's operating state is controlled to recharge the engine, including: if the SOC of the power battery is less than or equal to the target SOC corresponding to the charging mode, the HCU controls the EMS to start the engine and recharge the power battery with a larger power, and the engine's operating state is switched to recharge the engine.
[0057] In one possible implementation, the EMS controls the engine to replenish the power battery at a higher power, including but not limited to the EMS increasing the engine torque to the torque corresponding to the higher power, wherein the torque corresponding to the higher power is determined experimentally.
[0058] For example, in response to the SOC of the power battery being greater than a third reference percentage and the engine operating state being to recharge the engine, the engine operating state is switched to the state of stopping engine recharging, including: after the engine starts to recharge the power battery, if the SOC of the power battery is greater than the third reference percentage, the HCU controls the EMS to stop the engine from recharging the power battery, and the engine operating state is switched to the state of stopping engine recharging.
[0059] By activating the vehicle's memory switch in charging mode, the vehicle quickly enters a charging state. If the vehicle's SOC is less than or equal to the target SOC corresponding to the charging mode, the engine is controlled to replenish the power battery with higher power, ensuring that the vehicle can pass through road sections requiring greater power, such as hill climbing, and avoiding dangerous situations such as the vehicle running out of power.
[0060] In one possible implementation, the HMI can also display the vehicle's battery SOC, charge control mode, and engine operating status to provide prompts to the user.
[0061] This application embodiment obtains the SOC of the power battery and the vehicle's charge control mode, and determines the working state that the engine needs to perform next based on the SOC of the power battery and the charge control mode. That is, it determines whether to replenish the power battery through the engine and how to replenish the power battery through the engine, thereby ensuring the power performance of the hybrid vehicle while ensuring fuel economy, and keeping the power battery charge within the normal range to avoid the vehicle running out of power.
[0062] See Figure 3 This application provides a vehicle battery control device, which includes:

[0064] The second acquisition module 302 is used to acquire the vehicle's power control mode, which includes default mode, long-distance driving mode, power saving mode or charging mode.
[0065] The determination module 303 is used to determine the operating state of the vehicle's engine based on the SOC of the power battery and the power control mode, so that the engine can work according to the operating state of the engine.
