Embodiments of the present application are described in detail below with reference to the accompanying drawings.
FIG. 1 illustrates a flow chart of a method of energy management for a vehicle.
Referring to fig. 1, the application provides an energy management method of a vehicle, which is applied to a vehicle controller, and comprises the following steps:
and 102, acquiring the current residual electric quantity of the power battery and the current oil quantity of the vehicle in response to determining that the vehicle meets a preset low-speed running condition and the engine is required to charge the power battery.
In the step, when the vehicle meets the low-speed running condition and the engine is required to charge the power battery, the current residual electric quantity of the power battery and the current oil quantity of the vehicle are collected through each vehicle-mounted sensor, the collected data are sent to the whole vehicle controller, and the whole vehicle controller can further manage the energy of the vehicle according to the collected data, so that safe driving of the vehicle is ensured.
Further, when the engine is judged to be required to charge the power battery, judging whether the engine is required to charge the power battery according to the current residual electric quantity. After the whole vehicle controller obtains the current residual electric quantity of the power battery, judging whether the power battery needs to be charged, and when the current residual electric quantity reaches the requirement of charging, starting an engine to charge the power battery so as to ensure the normal running of the vehicle. When the engine is required to charge the power battery, the residual electric quantity is changed because the vehicle is always in the running process, so that the current residual electric quantity of the power battery is obtained again, and the whole vehicle controller can further manage the energy of the vehicle according to the collected current residual electric quantity and the collected current oil quantity, thereby ensuring the safe driving of the vehicle.
And 104, determining the allowable starting times of the engine according to the current residual electric quantity and the current oil quantity.
Specifically, when the engine needs to charge the power battery, the allowable starting times of the engine are determined according to the current residual electric quantity and the current oil quantity, so that the starting times of the engine when the engine charges the power battery are smaller than or equal to the allowable starting times.
Further, when the engine needs to charge the power battery, the allowable starting times of the engine are determined according to the current residual electric quantity and the current oil quantity, wherein when the current residual electric quantity and the current oil quantity are smaller, the starting times of the engine are limited to be smaller, when the current residual electric quantity and the current oil quantity are larger, the starting times of the engine are limited to be larger, and if the engine is not successfully started within the limited starting times of the engine, the vehicle is considered to be failed. The engine is limited to be started within the allowed starting times, so that the problem that the power battery is fed due to overdischarge of the electric quantity of the power battery caused by excessive starting of the engine is prevented.
And step 106, controlling the vehicle to be electrified in response to the starting times when the engine charges the power battery exceeds the allowed starting times.
In the step, the vehicle controller of the vehicle counts the requests sent when the engine is started, so that the engine starting times are obtained, after the engine starting times are obtained, whether the engine starting times exceed the allowed starting times is judged, if the engine starting times exceed the allowed starting times, the engine is not started successfully, the vehicle is controlled to be powered down, the problem that power battery feeding is caused in the running process of the vehicle is avoided, and the vehicle cannot run due to the fact that the power battery is too low, so that inconvenience is brought to a driver.
Based on the steps 102 to 106, in response to determining that the vehicle meets a preset low-speed driving condition and the engine is required to charge the power battery, acquiring the current residual electric quantity of the power battery and the current oil quantity of the vehicle; namely, the vehicle is in a pure electric mode when running at a low speed, and the engine is not started; acquiring the current residual electric quantity of the power battery and the current oil quantity of the vehicle; judging whether the engine needs to charge the power battery or not according to the current residual electric quantity; determining the allowable starting times of the engine according to the current residual electric quantity and the current oil quantity; when the charging is needed, the engine is required to be started, the allowable starting times of the engine are determined according to the residual electric quantity and the oil quantity, so that the engine is started according to the allowable starting times of the engine, and the waste of the electric quantity of the power battery caused by starting the engine for many times is avoided; and controlling the vehicle to be powered down in response to the number of starts when the engine charges the power battery exceeding the allowed number of starts. When the number of times of starting the engine exceeds the allowed number of times of starting, the vehicle is controlled to be powered down, and the phenomenon that the power battery is excessively discharged due to the fact that the engine is always started is avoided.
In some embodiments, the determining that the vehicle satisfies a preset low-speed driving condition includes:
acquiring a current driving mode and a current vehicle speed of the vehicle;
and determining that the vehicle meets the low-speed driving condition in response to the current driving mode being an electric-only mode and the current vehicle speed being less than a first vehicle speed threshold.
Specifically, in this step, when the vehicle is in the running condition, the current driving mode and the current vehicle speed of the vehicle are acquired. And judging whether the vehicle meets a preset low-speed driving condition according to the current driving mode and the current vehicle speed.
The running condition is that the automobile runs through the automobile, namely the speed of the automobile is greater than zero, and the power battery of the automobile is in a discharging state or the engine is in a starting state. Under the condition that the vehicle is in a running working condition, the current driving mode and the current vehicle speed are acquired through respective vehicle-mounted sensors, acquired data are sent to the whole vehicle controller, and the current running working condition of the vehicle can be further judged according to the current driving mode and the current vehicle speed. The working condition of the vehicle is detected in time, so that the vehicle is timely and timely subjected to energy management, and the electric quantity of the power battery is prevented from being excessively discharged.
Further, the source of power for the vehicle is typically powered by a power battery when the vehicle is traveling at low speed, and therefore, the vehicle is typically in an electric-only mode when traveling at low speed. When the vehicle is traveling at a high speed, the engine is required to assist. In this embodiment, when the vehicle is traveling at a low speed, the power battery of the vehicle supplies power to the vehicle, that is, consumes electric power of the power battery, and the engine is in a stopped state. Because the current vehicle is in the running condition, the power battery can be charged only through the engine, so that the electric quantity of the power battery can be ensured to meet the requirement of safely driving the vehicle.
The electric-only mode refers to that the power of the vehicle is provided by a power battery, and the engine is in a stop state. And judging whether the current driving mode is the pure electric mode or not and judging whether the current vehicle speed is smaller than a first vehicle speed threshold value so as to accurately determine whether the vehicle meets the low-speed driving condition or not.
In some embodiments, the determining that the engine is required to charge the power battery includes:
and determining that the engine needs to charge the power battery in response to the current residual electric quantity being smaller than a preset electric quantity threshold.
Specifically, the preset electric quantity threshold is a lower limit that the power battery needs to be charged, when the electric quantity of the power battery is smaller than the preset electric quantity threshold, the power battery needs to be charged, and because the vehicle is in a running working condition, the power battery can only be charged through the engine, and because the electric quantity of the power battery needs to be consumed when the engine is started, a certain electric quantity needs to be reserved for preparing to start the engine when the preset electric quantity threshold is set.
The power battery of the instruction book needs to be charged when the current residual electric quantity of the power battery is below 4%, and the vehicle is controlled to be powered down, so that the problem that the power battery is fed due to continuous consumption of the power battery by the vehicle is avoided.
In some embodiments, the determining the allowable number of starts of the engine according to the current remaining power and the current oil amount includes:
and inquiring and determining corresponding allowable starting times in a pre-constructed calibration table according to the current residual electric quantity of the power battery and the current oil quantity, wherein the calibration table is used for representing the corresponding relation among the current residual electric quantity, the current oil quantity and the allowable starting times.
Specifically, the above-mentioned pre-built calibration table includes the power battery power, the fuel amount of the vehicle, and the number of allowed starts corresponding to the power battery power and the fuel amount of the vehicle, and the pre-built table is calibrated as shown in table 1 below. When the current residual electric quantity is 30% and the current oil quantity is 3L, the allowable starting times of the engine are inquired in a pre-built calibration table to be 10 times, the engine is allowed to be started 10 times, and if the vehicle controller receives the 11 th starting request, whether the allowable starting times are exceeded or not is judged.
TABLE 1 Pre-built calibration Table
Fig. 2 shows a schematic diagram of controlling the under-vehicle current flow.
In some embodiments, referring to fig. 2, prior to determining the number of allowable starts of the engine, the method further comprises the steps of:
step 202, judging whether the current oil quantity is smaller than a preset oil quantity threshold value or not;
and 204, controlling the vehicle to be powered down in response to the current oil quantity being smaller than the preset oil quantity threshold.
Specifically, in this embodiment, by comparing the current oil amount with the preset oil amount threshold, it can be accurately determined whether the engine cannot be started due to the too small oil amount, and if the oil amount is too small, it is proved that the engine cannot be started normally due to the too small oil amount, and the reason that the engine cannot be started due to the start can be clearly known.
The control of the vehicle is that the vehicle is powered off, all equipment in the vehicle is powered off, namely all electric equipment such as voice equipment, display equipment and lighting equipment in the vehicle is powered off, so that the complete power-off of the vehicle is realized, and the power supply of a power battery is avoided.
Fig. 3 shows a schematic flow chart of the early warning information transmission.
In some embodiments, referring to fig. 3, before controlling the vehicle to power down, the method further comprises the steps of:
step 302, judging whether the current oil quantity is larger than or equal to a preset oil quantity threshold value;
and step 304, sending early warning information in response to the current oil quantity being greater than or equal to the preset oil quantity threshold.
Specifically, in this embodiment, by comparing the current oil amount with a preset oil amount threshold, it is preliminarily determined whether the engine is not started successfully due to the oil amount, and if the current oil amount is greater than or equal to the preset oil amount threshold, the instruction that the engine is not started successfully is not due to too little oil amount is sent to the vehicle screen by the vehicle controller, so that personnel can conveniently troubleshoot according to the early warning information.
For example, the early warning information can be displayed in a vehicle screen in a screen flashing mode through the early warning icon, and meanwhile, an early warning prompt tone is emitted. The text early warning information can be displayed on the screen, and the personnel can be warned and prompted in a voice broadcasting mode. The possible reasons can be voice broadcast only through the voice broadcast mode, so that the personnel can be warned.
In some embodiments, before sending the early warning information, the method further comprises:
comparing the current oil quantity with a preset oil quantity threshold;
searching a plurality of early warning information in a pre-built early warning information database according to the comparison result, determining an early warning information table, and sending the early warning information table as early warning information.
Specifically, the pre-built early warning information database stores a comparison result table of the current oil quantity and a preset oil quantity threshold value and early warning information corresponding to the result; and searching corresponding early warning information in the database and sending the information to a screen of the vehicle, so that a driver can conveniently check the reason of the failure of starting the transmitter.
Illustratively, the comparison results are stored in the early warning information database, as shown in table 2. When the vehicle controller detects that the current oil quantity is smaller than a preset oil quantity threshold value, the early warning information is as follows: the engine is not started successfully; or when the current oil quantity is detected to be larger than or equal to the preset oil quantity threshold value, corresponding early warning information is called from a pre-built early warning information database, the early warning information is sent to a vehicle screen in a list form, and the vehicle screen displays the early warning information in the list form.
For example, when the vehicle controller detects that the current oil amount is greater than or equal to the preset oil amount threshold, if the engine is not started successfully, the vehicle controller invokes early warning information into a pre-built early warning information database, wherein the early warning information is as follows: 1. the low pressure oil line is blocked, the pipeline loosens the oil leak, the high pressure oil pipe has the air body, the sprayer technical state is bad. 2. The power failure, poor contact of the electromagnetic switch and the slipping of the clutch of the transmission mechanism. 3. The cylinder gasket is damaged and leaked, the valve is not closed, and the piston cylinder sleeve is worn and leaked. 4. Air filter element blockage and other factors. And the early warning information is sent to a vehicle screen in a list form, the vehicle screen is displayed in a list form, and meanwhile, the whole vehicle controller controls the voice equipment to broadcast list contents so as to warn a driver to drive safely and conveniently check the reason that an engine is not started successfully.
