The message driving means that an ECU (Electronic Control Unit, ECU for short) of the engine sends a message through an instrument of the CAN longitudinal engine, and the message comprises data of an indicator lamp driven by the indicator instrument, namely the message driving realizes the driving of the indicator lamp through data transmission. The hard wire driving means that the indicator lamp is connected with the hard wire of the ECU, the ECU sends a signal to the indicator lamp through the hard wire, the signal comprises a high level and a low level, and the hard wire determines that the driving of the indicator lamp is realized through the high level and the low level.
As shown in fig. 1, the message state 1 represents a first CAN bus, the message state 2 represents a second CAN bus, and the first CAN bus and the second CAN bus are connected with one end of a message selecting switch, that is, the ECU CAN select the first CAN bus or the second CAN bus to send a message to the meter through the message selecting switch. In addition, the ECU is connected to the indicator lamp through a hard wire, and the ECU may drive the indicator lamp to light up based on the hard wire.
After determining that the driving mode of the indicator lamp is message state 1 or message state 2, the ECU sends the message state information to the signal source selection switch, and the signal source selection switch selects the message source in the message state to display the driving state of the indicator lamp as message driving. If the ECU determines that the state of the indicator lamp is hard-wire driving, the ECU sends information of the hard-wire state to the signal source selection switch, and the signal source selection switch selects the signal source in the hard-wire state to display that the driving state of the indicator lamp is hard-wire driving.

step S10, a first Controller Area Network (CAN) bus is used for sending a first indication message to an instrument of an engine, wherein the instrument feeds back a first response message when the instrument successfully drives an indication lamp indicated by the first indication message to be lightened;
in the present embodiment, the execution body is an engine. The engine is provided with a first CAN bus which is connected with an instrument of the engine. The meter may drive an indicator light of the engine to illuminate. When the engine needs to light the indicator lamp, the identification information of the indicator lamp is obtained, and then a message is generated through the identification information, namely the message comprises the information of the indicator lamp which needs to be driven by the instrument. The identification information characterizes the unique identity of the indicator light, for example, the identification information may be the number of the indicator light.
The engine transmits a message to an instrument of the transmitter by using the first CAN bus, and the message transmitted by the first CAN bus is defined as a first indication message. After the instrument receives the first indication message, the instrument analyzes the first indication message, so that the indication lamp needing to be driven is determined, and the instrument drives the indication lamp to be lighted. The instrument is provided with response logic, and the response logic is: after the indicator light is turned on, the instrument feeds back a message to the engine, and the fed back message is defined as a first response message.
In addition, the engine sends a first indication message through the first CAN bus and simultaneously sends a request message to the instrument, and the request message requests the instrument to feed back the information of the successfully-lighted indication lamp to the engine after the indication lamp is successfully driven to be lighted. The request message is defined as a first request message.
Step S20, when a first response message fed back by the instrument is received, setting the driving state of the indicator lamp as a message driving state.
When the engine receives a first response message fed back by the instrument, the engine can determine that the instrument successfully receives the first indication message, the instrument successfully drives an indication lamp indicated by the first indication message to be on, and the engine can set the driving state of the indication lamp as message driving.
In the technical scheme provided by the embodiment, the engine sends a first indication message to the instrument of the engine by using the first CAN bus, when the instrument successfully drives the indication lamp indicated by the first indication message to be on, the first response message is fed back to the engine, and the engine sets the driving state of the indication lamp as message driving based on the received first response message. According to the invention, the engine sends the indication message to the instrument through the CAN bus, the instrument feeds back the first response message to the engine after the indication lamp indicated by the drive indication message is lightened, the engine CAN determine that the instrument has received the message and successfully lightens the indication lamp based on the first response message, and the engine sets the driving state of the indication lamp as the message drive, namely, the engine determines whether the instrument has received the message and successfully drives the indication lamp to lighten according to the determination result, and sets the driving state of the indication lamp, so that the determination accuracy of the driving state of the indication lamp is improved.
Referring to fig. 3, fig. 3 is a second embodiment of a driving state determining method of an indicator lamp according to the present invention, based on the first embodiment, after step S10, further including:

and step S40, setting the driving state of the indicator lamp as a message 2 driver when receiving a second response message fed back by the instrument, wherein the message driver comprises a message 1 driver and a message 2 driver, and the message 1 driver is set when receiving a first response message.
In this embodiment, the engine is further provided with a second CAN bus, and the engine CAN select the first CAN bus or the second CAN bus to send a message to the meter through the message selecting switch.
The first preset duration may be any suitable value, for example, the first preset duration is 1min. When the engine does not receive a first response message fed back by the instrument within a first preset time period, the first CAN bus is switched to a second CAN bus, and the second CAN bus is used for sending the message to the instrument. The message sent through the second CAN bus is defined as a second indication message.
After the instrument receives the second indication message, the instrument analyzes the second indication message, so that the indication lamp to be driven is determined, and the instrument drives the indication lamp to light. The instrument is provided with response logic, and the response logic is: after the indicator light is turned on, the instrument feeds back a message to the engine, and the fed-back message is defined as a second response message.
In addition, the engine sends a second indication message through the second CAN bus and simultaneously sends a request message to the instrument, and the request message requests the instrument to feed back the information of the successfully-lighted indication lamp to the engine after the indication lamp is successfully driven to be lighted. The request message is defined as a second request message.
When the engine receives a second response message fed back by the instrument, the instrument can be determined to successfully receive the second indication message, the instrument successfully drives the indication lamp indicated by the second indication message to be on, and the engine can set the driving state of the indication lamp as the driving state of the message 2. The message drivers include a message 1 driver and a message 2 driver, the message 1 driver being set when the engine receives a first response message, and the message 2 driver being set when the engine receives a second response message.
Further, after the engine sends a second indication message to the instrument by using the second CAN bus, whether a second response message is received within a second preset duration is judged. The second preset duration may be any suitable value, for example, the second preset duration may be 2 minutes.
And if the second response message fed back by the instrument is received, setting the driving state of the indicator lamp as a message 2 driving state. If the second response message fed back by the instrument is not received within the second preset time, whether the indicator lamp is connected with the hard wire or not is detected. Specifically, the engine can detect whether the hard wire open circuit fault diagnosis is set, if not, the indication lamp is connected with the hard wire; if the indicating lamp is set, the indicating lamp is not connected with the hard wire.
When the indication lamp is not connected with the hard wire, the fault of the hard wire can be determined, and the engine outputs the indication information of the fault of the indication lamp, the fault of the hard wire and the message line, namely, the related fault of the hard wire connection of the indication lamp, the related faults of the unsuccessful receiving of the message 1 and the message 2 and the like are simultaneously reported. The engine may also set the driving state of the indicator light to a default state, which indicates that the indicator light is not lit. If the indicator light is connected with the hard wire, the driving state of the indicator light is set to be hard wire driving.
When the driving state of the indicator lamp is hard-wire driving, the engine turns off the reminding function of the message fault, namely the reminding information of the message fault is prevented from being sent out by the engine. When the driving state of the indicator lamp is message driving 1 or message driving 2, the engine turns off the reminding function of the hard line fault, namely the reminding information of the hard line fault is prevented from being reported by the engine.
In the technical scheme provided by the embodiment, when the engine does not receive the first response message fed back by the instrument within the first preset time, the second CAN bus is used for sending the second indication message to the instrument, if the second response message fed back by the instrument is received, the driving state of the indicator lamp is set to be the message 2 driving state, namely, the engine is provided with a plurality of CAN buses, so that the message CAN be successfully sent to the instrument.
In an embodiment, in addition, the hard wire drive and the message drive are provided with corresponding priorities, if the priority of the message drive is higher than that of the hard wire drive, the first CAN bus is adopted to send a first indication message to the instrument, if the first response message is not received within a first preset time period, the second CAN bus is adopted to send a second indication message to the instrument, if the second response message is not received within a second preset time period, whether the indication lamp is connected with the hard wire is detected, and if the indication lamp is connected with the hard wire, the driving state of the indication lamp is set to be the hard wire drive.
If the priority of the message drive is lower than that of the hard wire drive, the engine detects whether the indicator lamp is connected with the hard wire. If the indicator lamp is not connected with the hard wire, a first CAN bus is used for sending a first indicator message to the instrument, if the first response message is not received within a first preset time period, a second CAN bus is used for sending a second indicator message to the instrument, if the second response message is not received within a second preset time period, the indicator lamp is not connected with the hard wire and the prompting information of the fault of the message line is output, the driving state of the indicator lamp is set to be a default state, and the indicator lamp in the default state is not lighted.
