Based on the hardware structure, the embodiment of the method for controlling the assembly and distribution of the new energy commercial vehicle is provided.
Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the power distribution control method for the new energy commercial vehicle.
In a first embodiment, the method for controlling the assembly and distribution of the new energy commercial vehicle comprises the following steps:
and S10, acquiring the current enable switch state information, the whole vehicle state information and the loading state information.
It should be noted that the execution subject of this embodiment is a vehicle-mounted control device, which refers to a device that transmits a trigger signal of an instruction, and a command from a vehicle control unit, adjusts the running state of the device, detects and feeds back OBD information, and performs system management, and may also be other devices that have the same or similar functions, such as a soft start controller, and the like, which is not limited in this embodiment. In the present embodiment, a description is given taking an in-vehicle control apparatus as an example.
It can be understood that the enabling switch information refers to enabling button state information for interacting with a driver, and the enabling switch button state information is used for forming a comprehensive judgment condition of the power distribution module, and in this embodiment, the enabling switch information includes: valid state, invalid state. The whole vehicle state information refers to the current vehicle high-voltage state information, and current voltage and current signals are acquired through a sensor. The vehicle state information in this embodiment includes: high pressure state, low high pressure state. The loading state information indicates whether a modification module connected with a loading system of the current automobile is in a working state, and the loading state information in the embodiment includes: the working state of the upper garment and the non-working state of the upper garment. For example: when a driver operates the vehicle, the enabling switch button is invalid, the button information is in an invalid state, the whole vehicle is in a high-voltage state at the moment, and the upper system modification module connected with the power distribution system is in a working state.
And S20, judging whether the loading condition is met or not according to the acquired enable switch state information, the whole vehicle state information and the loading state information, and sending a loading instruction when the loading condition is met.
It should be understood that the acquired enable switch state information, the entire vehicle state information, and the loading state information are stored in an ECU storage unit in the vehicle-mounted control apparatus, i.e., a storage unit in the computer control module. The upper assembling condition refers to a judgment condition which needs to be comprehensively judged before the power distribution module performs power distribution control, and the upper assembling condition in the embodiment includes: and the upper part is provided with a power-taking condition and the upper part is provided with a power-off condition. For example: the driver operates the enable button, and can perform subsequent power-off or power-taking operation and send a loading instruction under the condition of meeting loading conditions.
Further, step S30 further includes: and if the loading condition is not met, sending the information of the condition which is not met, and not sending the loading instruction.
It should be understood that the loading condition is the above-mentioned comprehensive condition of enabling switch state information, vehicle state information and loading state information, and the unsatisfied condition information is sent to prompt the driver that the loading control cannot continue to operate, so that the driver can adjust the working state of the refitting module.
And step S30, determining the current power distribution circuit opening and closing state according to the loading instruction, and acquiring loading state information.
It should be understood that the loading instruction refers to a loading instruction obtained after the comprehensive loading condition judgment is performed, and in this embodiment, the loading instruction includes: and loading a power-off instruction and a power-taking instruction. The acquisition instruction is transmitted to the power distribution module through the message, and the uploading state information is acquired after the power distribution module performs power distribution operation. The power distribution operation is to control the current power distribution loop on-off state, and the loop on-off state in this embodiment includes a loop off state and a loop on state. The acquired loading state information refers to the operating state of the loading module at the moment acquired after the power distribution operation is performed.
Further, step S30 includes: when the current loading instruction is a loading power-taking instruction, setting the current power distribution loop to be in a closed state, controlling the interactive indicator lamp to be in a light-on state, and acquiring loading state feedback information; when the current loading instruction is a loading power-off instruction, the current power distribution loop is set to be in a disconnected state, the interactive indicator lamp is controlled to be in an off state, and loading state feedback information is acquired.
It should be understood that, under the condition that the obtained current uploading instruction is the uploading electricity-taking instruction, the instruction received by the power distribution system is the electricity-taking operation, so that the power distribution loop is set to be in a closed state, the instruction is sent to the man-machine interaction module through message information to control the indicator lamp and is displayed to be in a light-on state, the system provides high-voltage electricity utilization setting and obtains a working state fed back by the uploading module, and the working state fed back by the uploading module is obtained so as to enable the follow-up judgment to be carried out on the electricity-taking operation again. Under the condition that the obtained current loading instruction is a loading power-off instruction, the instruction received by the power distribution system is power-off operation, so that the power distribution loop is set to be in a disconnected state, the power distribution loop is sent to the man-machine interaction module control indicator lamp through message information and is displayed to be in a turned-off state, high-voltage power supply is not carried out, and the working state fed back by the loading module is obtained again so as to enable follow-up judgment to be carried out on power taking operation again.
And step S40, determining whether to carry out loading control again according to the loading state information.
It should be understood that, during the operation, when the upper module is in operation, if the power-off operation is performed, a problem of malfunction of the upper module may be caused, and thus it is necessary to determine whether the upper module is in an operation state. If the power taking operation is carried out, namely the closed loop operation, if the current loading module is not in the working state, the problem of improper operation in the power taking process is solved, and at the moment, the on-off state, the whole vehicle state and the relevant conditions of the loading working state need to be comprehensively enabled again to judge whether the loading power taking operation is carried out again. For example: when a driver operates the enable button to enable the upper equipment to work, the power taking operation is carried out after the comprehensive conditions of the power distribution system are met, a circuit is closed, whether the upper equipment works or not is detected, and if the upper equipment works, the power taking operation of the driver is finished. If the loading device does not work, the electricity taking operation of a driver is not completed, and the electricity taking operation needs to be carried out again, for example, as shown in the overall flow chart of the new energy commercial vehicle loading control system in fig. 3, the new energy commercial vehicle loading control system comprises an enable switch for transmitting a hard wire signal to an ECU, the loading system feeds back a message signal to the ECU, the ECU carries out comprehensive judgment and respectively transmits the message signal to a human-computer interaction module, so that the driver can carry out corresponding operation, and meanwhile, the ECU transmits the message signal to a power distribution system for carrying out related electricity taking and power off operations on the loading system, and feeds back the message signal to a human-computer interaction prompting lamp.
The present embodiment obtains the current enable switch state information, the entire vehicle state information and the loading state information; judging whether the loading condition is met or not according to the acquired enable switch state information, the whole vehicle state information and the loading state information, and sending a loading instruction when the loading condition is met; determining the current power distribution circuit opening and closing state according to the loading instruction, and acquiring loading state information; and determining whether to perform loading control again according to the loading state information. By the mode, closed-loop control of the loading process is achieved, human-computer interaction is performed to guarantee a safety strategy, so that the safety of the loading power supply process can be improved, and the possibility of damage to the whole vehicle and the loading due to misoperation of a driver is reduced.
In the first embodiment, as shown in fig. 4, the second embodiment of the new energy commercial vehicle on-board power distribution control method, the step S20, includes:
in step S211, if the loading condition is the loading power-taking condition, the enable switch state is an active state.
It can be understood that the loading condition is the loading power-taking condition, which means that when the working state of the whole vehicle is a high-voltage state, the loading state is a non-working state, the enabling switch state is controlled to be an effective state through hard-wire signal transmission, and at the moment, a driver can operate the enabling switch button to carry out loading power-taking operation.
And step S212, judging whether the current vehicle state is a high-pressure state.
It is understood that the high voltage state refers to whether the voltage and current of the vehicle at the time are in a high degree, mainly including an ac voltage and a dc voltage, and the dc high voltage is distributed at the position of the power battery to each component, for example: the direct current high voltage is connected between the power battery and the driving inverter, and the direct current high voltage is connected between the power battery and the high-voltage compressor. The alternating-current high voltage is mainly distributed between the inverter and the driving motor and between the charging interface and the vehicle-mounted charger. For example: the ac high voltage between the inverter and the driving motor is generally about 300V, and the ac high voltage between the charging interface and the vehicle-mounted charger is 220V of the external power grid. And the high-voltage state of the whole vehicle is detected by the output end of the power battery, and if a signal is detected, the signal is transmitted to the ECU.
And step S213, if the current vehicle state is a high-voltage state, judging whether the loading state is a non-working state.
It can be understood that when the state of the whole vehicle is a high-voltage state, if the power utilization conflict is easily caused if the loading state is not judged to be a working state or a non-working state, the power utilization module or the component is in fault, and therefore the fact that the loading state is the non-working state is confirmed to ensure that the power utilization conflict does not occur to cause damage to a relay or a motor, and the loading module transmits a loading non-working state signal in a hard-line mode.
In step S214, if the loading state is the non-operating state, a loading power-taking instruction is sent.
It can be understood that the loading state is a non-working state, which indicates that no power is used by the power utilization module, and the fault such as short circuit and insulation of the high-voltage system can not be caused by sending the loading power-taking command. For example: the driver wants to execute the power-getting operation of the loader, detects that the current state is the high-voltage state, and indicates that the loader state is the working state if the power-getting device is in the power-using state of the loader at the moment, and cannot send the power-getting instruction of the loader. The new energy commercial vehicle is provided with a power getting flow chart as shown in fig. 5, and a driver operates an upper mounting enabling button to be effective; the ECU synthesizes a comprehensive condition T1 formed by button conditions, the state of the whole vehicle, the loading state and the like, if the comprehensive condition T1 is not met, the loading enabling instruction is not sent, information is sent to a human-computer interaction system, and a driver is prompted; if the T1 condition is met, sending an uploading enabling instruction; after the high-voltage power distribution system receives a loading enabling instruction of the ECU system, the loading power supply loop is closed to supply power to the upper equipment, and meanwhile, a loading power supply signal is sent to light an A1 indicator lamp of the human-computer interaction system; and the loading system starts to work after supplying power, meanwhile, a working signal is fed back to the ECU, if the working signal is not fed back within the time t1, the ECU stops sending the loading enable, meanwhile, relevant information is sent to the human-computer interaction system, and a driver is prompted about abnormal loading work conditions.
In this embodiment, by determining the condition, if the loading condition is the loading electricity-taking condition, the enable switch state is an effective state; judging whether the current vehicle state is a high-pressure state or not; if the current vehicle state is a high-voltage state, judging whether the loading state is an idle state; and if the loading state is the non-working state, sending a loading electricity-taking instruction. Through the mode, whether the power-taking instruction of the upper assembly is sent or not is judged according to the power-taking condition of the upper assembly, so that a driver can safely operate in the power-taking process of the upper assembly to improve the power-taking efficiency of the upper assembly.
In the first embodiment, as shown in fig. 6, a third embodiment of the method for controlling the assembly and distribution of the new-energy commercial vehicle, where the step S20 includes:
in step S221, if the loading condition is a loading power-off condition, the enable switch state is an invalid state.
It can be understood that the loading condition is the loading power-taking condition, which means that when the working state of the whole vehicle is a lower high-voltage state, the loading state is the working state, namely the loading module is provided with corresponding electric equipment for carrying out power-using work, the enabling switch state is an invalid state at the moment through hard-wire signal transmission control, at the moment, if a driver can operate the enabling button, the power of the working equipment is cut off to cause invariance, and therefore the driver cannot operate the enabling switch button to carry out loading power-taking operation, and the enabling button state is set to be the invalid state.
And step S222, judging whether the current vehicle state is a low-high-pressure state.
It can be understood that the lower high-voltage state refers to whether the voltage and current of the automobile are in a lower degree at the moment, the power failure in the low-voltage state can avoid circuit faults caused by equipment in a working state as much as possible, the lower high-voltage state of the whole automobile is detected by the output end of the power battery, and if a signal is detected, the signal is transmitted to the ECU.
And step S223, if the current finished automobile state is a low-high-pressure state, judging whether the loading state is a working state.
It can be understood that when the whole vehicle state is a lower high-voltage state, if the upper loading state is not judged to be working or not, the upper loading state is judged to be the working state, the driver cannot operate the enabling button and further cannot influence the power module for the upper loading work, and the upper loading module transmits an upper loading working state signal in a hard-line manner.
In step S224, if the loading state is the working state, a loading power-off command is sent.
It can be understood that the loading state is a working state, which indicates that the power utilization module is installed to utilize power, and the power utilization module is to stop working to send a loading power-off instruction to the power distribution system to perform power-off operation. The new energy commercial vehicle loading and power off flow chart is shown in fig. 7, and a driver operates an loading enable button to be invalid; if the comprehensive condition T2 formed by the ECU comprehensive button condition, the whole vehicle state, the loading state and the like does not meet the T2 condition, the risk of power off during loading is determined, the loading power off command is not sent, information is sent to a man-machine interaction system, and the reason that the power off is not conducted is prompted to a driver; if the T2 condition is met, sending an on-loading power-off instruction; after receiving a loading power-off instruction of the ECU system, the high-voltage power distribution system disconnects a loading power supply loop and simultaneously sends a loading power supply cancelling signal to turn off an A1 indicator lamp of the human-computer interaction system; after the loading system stops working, the loading power supply is stopped, and the automatic realization can be realized in the high-voltage process of the vehicle.
According to the embodiment, through judging the condition, if the loading condition is the loading power-off condition, the enabling switch state is an invalid state; judging whether the current vehicle state is a low-high-pressure state or not; if the current finished automobile state is a low-pressure state, judging whether the loading state is a working state; and if the loading state is the working state, sending a loading power-off instruction. Through the mode, whether the power-off instruction of the loading equipment is sent or not is judged according to the power-off condition of the loading equipment, so that a driver can safely operate in the power-off process of the loading equipment, and the power-off of working equipment caused by misoperation is prevented.
In addition, the embodiment of the invention also provides a storage medium, wherein the storage medium stores a new energy commercial vehicle-mounted power distribution control program, and the new energy commercial vehicle-mounted power distribution control program is executed by a processor to realize the steps of the new energy commercial vehicle-mounted power distribution control method.
Since the storage medium adopts all technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved, and details are not repeated herein.
In addition, referring to fig. 8, an embodiment of the present invention further provides a new energy commercial vehicle-mounted power distribution control device, where the new energy commercial vehicle-mounted power distribution control device includes:
the acquiring module 10 is used for acquiring the current enable switch state information, the whole vehicle state information and the loading state information;
and the interaction module 20 is configured to judge whether the loading condition is met according to the acquired enable switch state information, the entire vehicle state information, and the loading state information, and send a loading instruction when the loading condition is met.

and the loading module 40 is used for determining whether to perform loading control again according to the loading state information.
The present embodiment obtains the current enable switch state information, the entire vehicle state information and the loading state information; judging whether the loading condition is met or not according to the acquired enable switch state information, the whole vehicle state information and the loading state information, and sending a loading instruction when the loading condition is met; determining the current power distribution circuit opening and closing state according to the loading instruction, and acquiring loading state information; and determining whether to perform loading control again according to the loading state information.
