As shown in fig. 1, the electric balance control device for a whole vehicle may include: a processor 1001, such as a Central Processing Unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Wherein a communication bus 1002 is used to enable connective communication between these components. The user interface 1003 may include a Display screen (Display), an input unit such as a Keyboard (Keyboard), and the optional user interface 1003 may also include a standard wired interface, a wireless interface. The network interface 1004 may optionally include a standard wired interface, a WIreless interface (e.g., a WIreless-FIdelity (WI-FI) interface). The Memory 1005 may be a Random Access Memory (RAM) Memory, or may be a Non-Volatile Memory (NVM), such as a disk Memory. The memory 1005 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the configuration shown in fig. 1 does not constitute a limitation of the overall vehicle electrical balance control apparatus, and may include more or fewer components than those shown, or some components in combination, or a different arrangement of components.
As shown in fig. 1, the memory 1005, which is a storage medium, may include therein an operating system, a data storage module, a network communication module, a user interface module, and a vehicle electric balance control program.
In the entire vehicle electric balance control apparatus shown in fig. 1, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the vehicle electrical balance control device of the present invention may be disposed in the vehicle electrical balance control device, and the vehicle electrical balance control device calls the vehicle electrical balance control program stored in the memory 1005 through the processor 1001, and executes the vehicle electrical balance control method provided by the embodiment of the present invention.
Based on the above-mentioned vehicle electrical balance control device, an embodiment of the present invention provides a vehicle electrical balance control method, and referring to fig. 2, fig. 2 is a flowchart of a first embodiment of the vehicle electrical balance control method of the present invention.
In this embodiment, the electric balance control method for a whole vehicle includes the following steps:
step S10: and acquiring the voltage of a generator of the target vehicle, and judging whether the voltage of the generator is smaller than a calibration voltage or not.
It should be noted that the execution main body of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device or a vehicle electric balance control device capable of implementing the above functions. The present embodiment and the following embodiments will be described below by taking the electric balance control device for a whole vehicle as an example.
It should be noted that the generator voltage may be a generated voltage of a generator of the target vehicle, and the calibration voltage may be a calibration voltage obtained in advance through an electrical balance test. The electric balance test may be to completely turn on the electric equipment of the target vehicle, so that the sum of the overall electric current of the target vehicle is the highest, and obtain the generator voltage at that time as the calibration voltage.
Further, after the step of determining whether the generator voltage is less than the calibration voltage, the method further includes: and when the generator voltage is greater than or equal to the calibration voltage, determining that the target vehicle has no electric balance fault.
In specific implementation, the whole vehicle electric balance control device acquires the voltage of a generator of a target vehicle, acquires a calibration voltage, compares the voltage of the generator with the calibration voltage, and judges whether the voltage of the generator is smaller than the calibration voltage.
Step S20: and when the voltage of the generator is smaller than the calibration voltage, determining that the target vehicle is in electric balance fault.
It should be understood that the calibration voltage is a voltage of the generator after the voltage of the generator is pulled down when the target vehicle has an electrical balance fault, and therefore, when the generator voltage is less than the calibration voltage, it may be determined that the current voltage of the generator is pulled down because of the occurrence of the electrical balance fault, and therefore, it may be determined that the target vehicle has the electrical balance fault.
Further, in order to make the user more intuitively know the use condition of the vehicle, after the step of determining that the target vehicle is in electrical balance fault when the generator voltage is less than the calibration voltage, the method further includes: controlling an instrument of the vehicle to display preset prompt information; and starting double flashes of the vehicle and sending fault information to the target user terminal. The preset prompt information can be information for prompting that the electric balance fault occurs in the vehicle of the user, and the target user terminal can be a mobile phone terminal of a vehicle owner.
Step S30: when the target vehicle is in an electrical balance fault, obtaining the generator current of the target vehicle and the current power utilization current of the target vehicle, and determining the target rotating speed of the target vehicle according to the generator current, the power utilization current and a preset generator external characteristic curve.
It should be noted that the generator current may be a generator current of a generator of the target vehicle in a current limit power generation situation, and the current power utilization current of the target vehicle may be a sum of current power utilization currents of all power consumers on the target vehicle. The preset generator external characteristic curve may be a corresponding curve of current and rotation speed. The target rotating speed can be the idle rotating speed required by the vehicle under the condition of meeting the power consumption of the whole vehicle.
Referring to fig. 3, fig. 3 is a schematic diagram of a preset external characteristic curve of the generator in the first embodiment of the vehicle electric balance control method of the present invention.
It is to be understood that determining the target rotational speed of the target vehicle based on the generator current, the electricity-using current, and a preset generator-external characteristic curve may be determining a battery supplement current based on the generator current and the electricity-using current; searching a rotating speed value corresponding to the supplementary current of the storage battery in the preset external characteristic curve of the generator; and taking the rotating speed value as the target rotating speed of the target vehicle. .
In specific implementation, for example, the current consumption of the electrical equipment of the whole vehicle of the target vehicle is 88.9A, the limit generating current of the generator is only 78.8A, the supplementary current of the storage battery is that the storage battery needs to supply power to the electrical equipment of the whole vehicle by 10.1A to meet the current consumption of the target vehicle, at this time, the output current which needs to be supplemented by the storage battery is determined to be 10.1A according to the current of the generator and the current consumption, and the rotating speed value corresponding to the supplementary current of the storage battery is searched in the preset external characteristic curve of the generator by combining with fig. 3, and is 1100 r/min; and taking the rotating speed value 1100r/min as the target idle rotating speed of the target vehicle.
Step S40: increasing the actual rotational speed of the target vehicle to the target rotational speed.
It should be noted that the actual rotation speed may be an actual vehicle idle rotation speed of the target vehicle under the current condition, and the target rotation speed may be an idle rotation speed required by the vehicle under the condition of meeting the requirement of power consumption of the entire vehicle.
In a specific implementation, for example, the current vehicle idle speed, which is the actual rotation speed of the target vehicle, is 900r/min, the output current required to be supplemented by the storage battery is determined to be 10.1A according to the generator current of the target vehicle and the electricity consumption current of the target vehicle, and the target rotation speed of the target vehicle is 1100r/min by referring to the preset generator external characteristic curve of fig. 3. At the moment, the idling speed of the vehicle is adjusted to be 900r/min before the idling speed is adjusted to be 1100r/min, at the moment, the power generation capacity of the generator is increased, the generator can supply power to the electric appliances of the whole vehicle and also can charge the storage battery, and the storage battery is ensured to be in the optimal working state.
Further, in order to save energy consumption of the vehicle, after the step of increasing the actual rotation speed of the target vehicle to the target rotation speed, the method further includes: acquiring the generator voltage of the target vehicle in real time; acquiring a second calibration voltage of the target vehicle, and taking the actual rotating speed as a second target rotating speed when the voltage of the generator is greater than the second calibration voltage; and adjusting the rotating speed of the target vehicle to be the second target rotating speed.
It should be noted that the second calibration voltage may be a voltage of the generator when it can be determined that the electrical balance fault of the vehicle is resolved, for example, the calibration voltage is 12.7V, and when the voltage of the generator is 13.7V, the current vehicle has resolved the electrical balance fault, at this time, 13.7V may be used as the second calibration voltage. The actual rotational speed may be an actual idle rotational speed before the target vehicle has an electrical balance failure.
It should be understood that when the generator voltage is greater than the second calibration voltage, the target vehicle has no electric balance fault, and at this time, it is no longer necessary to increase the idle speed of the target vehicle to the target speed at the time of the electric balance fault, because the target speed is greater than the previous actual idle speed of the vehicle, which may cause energy consumption, and in order to save the use cost of the vehicle, the idle speed of the target vehicle may be reduced to the idle speed at the time of the previous electric balance fault.
Further, in order to save the use cost of the vehicle, the step of obtaining the second calibration voltage of the target vehicle is preceded by: acquiring a calibration voltage of the target vehicle; and determining the second calibration voltage according to the calibration voltage and a preset threshold value.
It should be noted that the preset threshold may be a difference between a voltage of the generator and a calibration voltage when the electrical balance fault of the vehicle is resolved. For example, the calibration voltage is 12.7V, and when the voltage of the generator of the vehicle is 13.7V, the electrical balance fault of the vehicle is resolved, and at this time, the preset threshold may be 1V. The preset threshold may also be adaptively adjusted according to results of different vehicles during the test, which is not limited herein.
In the embodiment, the generator voltage of the target vehicle is obtained, and whether the generator voltage is smaller than the calibration voltage is judged; when the voltage of the generator is smaller than the calibration voltage, determining that the target vehicle is in an electric balance fault; when the target vehicle is in an electrical balance fault, acquiring a generator current of the target vehicle and a current power utilization current of the target vehicle, and determining a target rotating speed of the target vehicle according to the generator current, the power utilization current and a preset generator external characteristic curve; increasing the actual rotational speed of the target vehicle to the target rotational speed. For current electric balance trouble's mode of solving the vehicle through the electric current that reduces with electrical apparatus, the electric balance problem of whole car can be solved to the above-mentioned mode of this embodiment under the power consumption demand that does not change whole car, ensures that the vehicle does not have the risk of insufficient power, promotes user experience and feels.
Referring to fig. 4, fig. 4 is a schematic flow chart of a vehicle electric balance control method according to a second embodiment of the present invention.
Based on the first embodiment, in this embodiment, before the step S10, the method further includes:
step S001: and obtaining a test result of the target vehicle with the environment bin for testing.
It should be noted that the test with the environmental chamber may be performed under the limit conditions of rain night in summer and/or idling snow night in winter, and the like, and the test with the environmental chamber may also be performed under other tests that enable the vehicle to be started under all the electrical appliances and to reach the maximum power consumption, where the limit condition is to obtain the limit condition that the vehicle is started under all the electrical appliances and to reach the maximum power consumption, and all the test conditions that can satisfy the above purpose may be used as the test with the environmental chamber in this embodiment, and this embodiment is not limited herein. The test result may be the result of the information related to the power demand of the entire vehicle and the power supply capability of the power supply system when the target vehicle is tested with the environmental chamber, for example, the test result may be the generated current of the generator when the vehicle is tested with the environmental chamber, the limit power consumption current of the entire vehicle, and the like,
step S002: and obtaining the limit generating current and the limit using current of the target vehicle according to the test result.
It should be noted that the limit generated current may be a generated current of a generator of the vehicle under the test with the environmental chamber, and the limit used current may be a used current of a whole vehicle under the test with the environmental chamber.
Step S003: and judging whether the target vehicle is an electric balance fault or not according to the limit generating current and the limit using current.
It should be understood that, when the limit generating current is smaller than the limit power consumption current, if the power consumption requirement of the whole vehicle needs to be met, the storage battery of the vehicle needs to supply power to the electrical appliances of the whole vehicle, and the storage battery discharges for a long time, which seriously affects the restarting of the vehicle. At this time, it is determined that an electrical balance fault has occurred in the vehicle.
Step S004: and when the target vehicle is in the electric balance fault, acquiring the current generator voltage of the target vehicle, and taking the current generator voltage as the calibration voltage.
It should be noted that the calibration voltage may be a calibration voltage capable of determining whether the vehicle has an electrical balance fault, and when the generator voltage of the vehicle is less than the calibration voltage, it may be determined that the vehicle has the electrical balance fault.
It will be appreciated that the power generation capability of the generator will drop very quickly in the event of a failure of the electrical balance of the vehicle. The voltage of the generator will be pulled low. At this time, the electric balance fault occurs to the vehicle, the voltage of the current generator is the voltage when the electric balance fault occurs to the vehicle, the voltage of the generator is obtained, and the voltage of the current generator is used as the calibration voltage. And judging whether the vehicle is in electric balance fault or not according to the calibration voltage.
In the embodiment, before the step of obtaining the voltage of the generator of the target vehicle and judging whether the voltage of the generator is smaller than the calibration voltage, a test result of the target vehicle with an environment bin for testing is obtained; obtaining the limit generating current and the limit using current of the target vehicle according to the test result; determining whether the target vehicle is an electric balance fault according to the limit generating current and the limit power utilization current; and when the target vehicle is in the electric balance fault, acquiring the current generator voltage of the target vehicle, and taking the current generator voltage as the calibration voltage. In the embodiment, before the target vehicle is judged to have the electric balance fault, the environment cabin is used for testing to obtain the calibration voltage when the vehicle has the electric balance fault, so that whether the vehicle has the electric balance fault can be judged according to the calibration voltage subsequently, whether the vehicle has the electric balance fault under the condition of limited power consumption can also be obtained, and if the vehicle still does not have the electric balance fault under the condition of limited power consumption, the vehicle can be considered not to have the electric balance fault.
