Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

An embodiment of the present application provides a method for controlling electric quantity of a vehicle, please refer to fig. 1, which is a schematic diagram illustrating an implementation environment of the method provided in the embodiment of the present application. The implementation environment may include: EMS (Engine Management System ) 11, hcu (Hybrid Control Unit, hybrid vehicle overall controller) 12, bms (Battery Management System ) 13 and HMI (Human Machine Interface, human-machine interface) 14.

Generally, the HCU12 reads the SOC of the power battery of the vehicle from the BMS13, and the HCU12 acquires the charge control mode of the vehicle and the set target SOC from the HMI14, which are set, for example, by a user touch on the HMI 14. The HMI14 determines the operating state of the engine of the vehicle from the SOC of the power battery, the set target SOC, the charge control mode, the default target SOC of the power battery, and the vehicle running speed, and the HCU12 controls the operating state of the engine through the EMS 11. The HMI14 displays the SOC of the power battery of the vehicle, the charge control mode, and the operating state of the engine. Wherein the EMS11, the HCU12, the BMS13 and the HMI14 establish communication connection through buses.

Based on the implementation environment shown in fig. 1, the embodiment of the present application provides a method for controlling the electric quantity of a vehicle, as shown in fig. 2, and the method is applied to an HCU, for example, and the method includes steps 201 to 203.

In step 201, the SOC of the power battery of the vehicle is obtained, where the SOC of the power battery is a percentage of the remaining power of the power battery to the total power.

In one possible implementation, the SOC of the power battery is a percentage of a remaining power of the power battery to a total power, and the obtaining the SOC of the power battery of the vehicle includes: the HCU reads the SOC of the power battery of the vehicle from the BMS through the bus. Wherein, BMS is located the vehicle, monitors the SOC, voltage and the temperature of battery in real time. The bus may be a CAN (Controller Area Network ) bus, for example.

In step 202, a power control mode of the vehicle is acquired, wherein the power control mode includes a default mode, a long-distance driving mode, a power saving mode, or a charging mode.

For example, a user may select a power control mode of the vehicle on an HMI of the vehicle, wherein the power control mode includes a default mode, a long distance travel mode, a power saving mode, or a charging mode. Optionally, after the user selects a certain power control mode, acquiring the power control mode of the vehicle includes: the HCU obtains the power control mode of the vehicle from the HMI through the CAN bus.

In one possible implementation, after the vehicle is first powered on, before the HCU receives the power control mode selected by the user, the power control mode of the vehicle is a default mode.

In step 203, the operating state of the engine of the vehicle is determined according to the SOC and the electric quantity control mode of the power battery, so that the engine operates according to the operating state of the engine, the operating state of the engine includes the engine performing power replenishment or the engine stopping power replenishment, and the initial operating state of the engine is the engine performing power replenishment.

Optionally, after determining the SOC and the electric quantity control mode of the power battery, determining the working state of the engine of the vehicle according to the SOC and the electric quantity control mode of the power battery, wherein the working state of the engine comprises that the engine is charged or the engine stops charging, and before determining the working state of the engine of the vehicle according to the SOC and the electric quantity control mode of the power battery, defaulting the initial working state of the engine to the engine stop charging.

In one possible implementation, in response to the charge control mode being a 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 travel speed of the vehicle is obtained, the first reference percentage being a default target SOC of the power battery; controlling the working state of the engine according to the running speed of the vehicle; and controlling the working state of the engine to be switched to the engine stop power supply in response to the working state of the engine being the power supply of the engine and the SOC of the power battery being greater than a third reference percentage, wherein the third reference percentage is greater than the first reference percentage.

For example, in the case where the charge control mode of the vehicle is the default mode, if the SOC of the power battery is greater than the first reference percentage, the operating state of the engine keeps the engine stopped from supplementing electricity, and the vehicle is driven to run by the charge of the power battery. A state in which the engine-driven vehicle is running is obtained, and if the engine stops driving the vehicle to run, the vehicle is run in the pure electric state. The first reference percentage is a default target SOC of the power battery, and for example, an SOC that can ensure that the vehicle will not run out of power under normal conditions may be set as the default target SOC of the power battery, for example, the first reference percentage may be 20%, or the first reference percentage may be modified according to actual requirements.

Optionally, in the case where the charge control mode of the vehicle is the default mode, if the SOC of the power battery is less than or equal to the first reference percentage and greater than the second reference percentage, acquiring the running speed of the vehicle includes: the HCU obtains the speed of the vehicle from the vehicle's central control system via the CAN bus. The second reference percentage is smaller than the first reference percentage, for example, the second reference percentage may be 15%, or the second reference percentage may be modified according to actual requirements.

Illustratively, after the traveling speed of the vehicle is obtained, controlling the operating state of the engine according to the traveling speed of the vehicle includes: and controlling the working state of the engine to supplement power to the engine in response to the running speed of the vehicle being greater than the first reference speed.

In one possible implementation, if the running speed of the vehicle is greater than the first reference speed, the HCU controls the EMS so that the engine is started to recharge the power battery and the operating state of the engine is switched to recharge the engine. If the running speed of the vehicle is less than or equal to the first reference speed, the working state of the engine is kept as the engine stops supplementing electricity, and the vehicle is driven to run through the electric quantity of the power battery. A state in which the engine-driven vehicle is running is obtained, and if the engine stops driving the vehicle to run, the vehicle is run in the pure electric state. The first reference speed may be, for example, 30 km/h, or may be adjusted as appropriate.

For example, in response to the operating state of the engine being engine-powered and the SOC of the power cell being greater than a third reference percentage, controlling the operating state of the engine to switch to engine-off power-supplementing includes: after the engine starts to supplement power for the power battery, if the SOC of the power battery is larger than a third reference percentage, the HCU controls the EMS to stop the engine to supplement power for the power battery, and the working state of the engine is switched to stop the power supplement for the engine. Alternatively, the third reference percentage may be the first reference percentage plus 5%, and the third reference percentage may be adjusted according to actual needs, but it is necessary to ensure that the third reference percentage is greater than the first reference percentage.

Under the default mode, the vehicle drives the vehicle to run through the electric quantity of the power battery under the condition that the SOC of the power battery is larger than a first reference percentage, the SOC of the power battery is smaller than or equal to the first reference percentage and larger than a second reference percentage, the running speed of the vehicle is smaller than the first reference speed, and the SOC of the power battery after the engine is started is larger than a third reference percentage, so that the vehicle runs in a pure electric state, and the vehicle can obtain more pure electric range. This is generally applicable to urban operating conditions.

In one possible implementation, in response to the power control mode being a power saving mode, a target SOC corresponding to the power saving mode is obtained; acquiring the running speed of the vehicle 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; controlling the working state of the engine according to the running speed of the vehicle; controlling the working state of the engine to supplement power for the engine in response to the SOC of the power battery being smaller than the first reference percentage; and controlling the working state of the engine to be switched to the engine stop power supply in response to the working state of the engine being the power supply of the engine and the SOC of the power battery being greater than a third reference percentage, wherein the third reference percentage is greater than the first reference percentage.

For example, when the power control mode is the power saving mode, the user may set a target SOC corresponding to the power saving mode on the HMI of the vehicle, and after the user sets the target SOC corresponding to the power saving mode, the HCU acquires the target SOC corresponding to the power saving mode from the HMI through the CAN bus. For example, the target SOC for the power saving mode may be in the range of 30% to 70%.

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 a first reference percentage, obtaining a running speed of the vehicle includes: the HCU obtains the speed of the vehicle from the vehicle's central control system via the CAN bus. Illustratively, after the traveling speed of the vehicle is obtained, controlling the operating state of the engine according to the traveling speed of the vehicle includes: and controlling the working state of the engine to supplement power for the engine in response to the running speed of the vehicle being greater than the second reference speed.

Optionally, if the running speed of the vehicle is greater than the second reference speed, the HCU controls the EMS to enable the engine to start to supplement power to the power battery, the operating state of the engine is switched to the engine to supplement power, and the EMS controls the engine to operate in the economy-saving interval. If the running speed of the vehicle is less than or equal to the second reference speed, the working state of the engine keeps the engine to stop supplementing electricity, the vehicle is driven to run through the electric quantity of the power battery, the running state of the engine driven vehicle is obtained, and if the engine stops driving the vehicle to run, the vehicle runs in a pure electric state. The second reference speed may be, for example, 80 km/h, or may be adjusted as practical.

Illustratively, the EMS controls the engine to make-up for power in an economy fuel-saving interval, including, but not limited to, the EMS adjusting the torque of the engine to an economy fuel-saving torque interval, wherein the fuel-saving torque interval may be determined experimentally.

In one possible implementation, controlling the operating state of the engine to supplement power to the engine in response to the SOC of the power cell being less than a first reference percentage includes: if the SOC of the power battery is smaller than the first reference percentage, the HCU controls the EMS to enable the engine to start to supplement electricity for the power battery, and the working state of the engine is switched to the engine to supplement electricity.

For example, in response to the operating state of the engine being engine-powered and the SOC of the power cell being greater than a third reference percentage, controlling the operating state of the engine to switch to engine-off power-supplementing includes: after the engine starts to supplement power for the power battery, if the SOC of the power battery is larger than a third reference percentage, the HCU controls the EMS to stop the engine to supplement power for the power battery, and the working state of the engine is switched to stop the power supplement for the engine.

Optionally, in response to the electric quantity control mode being a long-distance travel mode, acquiring a distance from a current position of the vehicle to a destination, a congestion condition of a current travel section of the vehicle, and a congestion condition of a next travel section of the vehicle; determining a target SOC corresponding to a long-distance running mode according to the distance from the current position of the vehicle to the destination, the congestion condition of the current running road section of the vehicle and the congestion condition of the next running road section of the vehicle, wherein the target SOC corresponding to the long-distance running mode comprises a first target SOC and a second target SOC; controlling the working state of the engine to supplement power for the engine in response to the SOC of the power battery being less than or equal to the first target SOC; and controlling the working state of the engine to be switched to the engine stop power supply in response to the SOC of the power battery being greater than the second target SOC and the working state of the engine being the engine power supply.

For example, in the case where the power control mode is the long distance travel mode, the user may set a destination on the HMI of the vehicle, the HCU acquires the destination from the HMI through the CAN bus, and then sends the destination to the navigation system through the CAN bus, and determines a distance from the current position of the vehicle to the destination, a congestion condition of a current travel section of the vehicle, and a congestion condition of a next travel section of the vehicle based on the destination. The navigation system is installed on a vehicle, can collect the position and congestion of a road, and calculates the road distance between places.

In one possible implementation manner, after determining a distance from a current location of a vehicle to a destination, a congestion condition of a current driving road section of the vehicle, and a congestion condition of a next driving road section of the vehicle, determining a target SOC corresponding to a long distance driving mode according to the distance from the current location of the vehicle to the destination, the congestion condition of the current driving road section of the vehicle, and the congestion condition of the next driving road section of the vehicle, includes: the distance from the current position of the vehicle to the destination, the congestion condition of the current running road section of the vehicle and the congestion condition of the next running road section of the vehicle are classified, and the target SOCs corresponding to different long-distance running modes are matched based on the different distances from the current position of the vehicle to the destination, the congestion condition of the current running road section of the vehicle and the congestion condition of the next running road section of the vehicle, and the target SOCs corresponding to the long-distance running modes comprise a first target SOCs and a second target SOCs. The first target SOC indicates a threshold value for starting the engine to supplement power to the power battery, and the second target SOC indicates a threshold value for stopping the engine to supplement power to the power battery.

Optionally, in response to the SOC of the power battery being less than or equal to the first target SOC, controlling the operating state of the engine to supplement power to the engine includes: if the SOC of the power battery is smaller than or equal to the first target SOC, the HCU controls the EMS to enable the engine to start to supplement electricity for the power battery, and the working state of the engine is switched to the engine to supplement electricity.

For example, in response to the SOC of the power battery being greater than the second target SOC and the operating state of the engine being engine-supplied, controlling the operating state of the engine to switch to engine-off-supply includes: after the engine starts to supplement power for the power battery, if the SOC of the power battery is larger than the second target SOC, the HCU controls the EMS to stop the engine to supplement power for the power battery, and the working state of the engine is switched to stop the power supplement for the engine.

In the long-distance running mode, the SOC of the engine starting power supply and the SOC of the engine stopping power supply corresponding to long-distance running are selected by combining the distance from the current position of the vehicle to the destination, the congestion condition of the current running road section of the vehicle and the congestion condition of the next running road section of the vehicle, so that the SOC of the power battery can be ensured, and the fuel economy can be ensured while the long-distance running of the vehicle is finished.

In one possible implementation, in response to the power control mode being a charging mode and the memory switch of the vehicle being turned on, controlling the vehicle to store a target SOC corresponding to the charging mode before each power down; reading a target SOC corresponding to a charging mode stored before the last power-down of the vehicle; controlling the working state of the engine to supplement electricity for the engine in response to the SOC of the power battery being smaller than or equal to the target SOC corresponding to the charging mode; and controlling the working state of the engine to be switched to the engine stop power supply in response to the SOC of the power battery being greater than the third reference percentage and the working state of the engine being the engine power supply.

For example, in the case where the charge control mode is the charging mode and the memory switch of the vehicle is turned on, the HCU stores the target SOC corresponding to the charging mode before each power-down, and when the vehicle is powered up next time, sets the charge control mode of the vehicle to the charging mode and reads the target SOC corresponding to the charging mode stored before the last power-down. The memory switch of the vehicle is positioned on the vehicle and used for starting the storage of the target SOC corresponding to the charging mode.

Optionally, in response to the SOC of the power battery being less than or equal to the target SOC corresponding to the charging mode, controlling the operating state of the engine to supplement power to the engine includes: if the SOC of the power battery is smaller than or equal to the target SOC corresponding to the charging mode, the HCU controls the EMS to enable the engine to start and the power of the power battery is supplemented by the larger power, and the working state of the engine is switched to the engine for supplementing.

In one possible implementation, the EMS controls the engine to recharge the power battery with greater power, including but not limited to, the EMS increasing the torque of the engine to a high power corresponding torque, where the high power corresponding torque is determined experimentally.

For example, in response to the SOC of the power battery being greater than the third reference percentage and the operating state of the engine being engine-on, controlling the operating state of the engine to switch to engine-off power-on includes: after the engine starts to supplement power for the power battery, if the SOC of the power battery is larger than a third reference percentage, the HCU controls the EMS to stop the engine to supplement power for the power battery, and the working state of the engine is switched to stop the power supplement for the engine.

By turning on the memory switch of the vehicle in the charging mode, the vehicle can quickly enter the charging state, and if the SOC of the vehicle is smaller than or equal to the target SOC corresponding to the charging mode, the engine is controlled to supplement electricity by taking larger power as a power battery, so that the vehicle can be ensured to pass through a road section requiring larger power such as a climbing road, and dangerous situations such as power shortage and the like of the vehicle are avoided.

In one possible implementation. The SOC of the power battery, the electric quantity control mode and the working state of the engine of the vehicle can be displayed through the HMI for prompting a user.

According to the method and the device for controlling the power of the hybrid electric vehicle, the SOC of the power battery and the electric quantity control mode of the vehicle are obtained, the working state of the engine, which is needed to be executed next, is determined according to the SOC of the power battery and the electric quantity control mode, namely whether the power battery is supplemented by the engine or not and how the power battery is supplemented by the engine or not are determined, so that the power performance of the hybrid electric vehicle is ensured, the fuel economy is ensured, the electric quantity of the power battery is kept in a normal range, and the power shortage of the vehicle is avoided.
