In one possible embodiment, please refer to fig. 2 together, and fig. 2 is a flow chart of an automatic flameout process of a refueling vehicle according to a second embodiment of the present application. Before the judging the state of the fuel tank of the vehicle, the method further comprises the following steps: s100, reading the current vehicle type, and establishing communication with the vehicle according to the current vehicle type.
Specifically, since the protocol type of the Vehicle cannot be known in advance, before the state of the Vehicle oil tank is judged, a Vehicle Identification Number (VIN) reading command is sent to the Vehicle once according to all the protocol types until the VIN code returned by the Vehicle is received. Common types of protocols for such vehicles are: controller Area Network (CAN), Keyword Protocol (KWP), International Organization Standardization 9141(International Organization for Standardization 9141, ISO9141), Pulse Width Modulation (PWM), Variable Pulse Width Modulation (VPW).

And sending a reading command 0x22F109 to the ECU of the vehicle oil tank in a real-time cycle mode. And the state data returned by the ECU receiving the vehicle oil tank is 0x62F10901, the state of the vehicle oil tank is judged according to the rightmost data sorted from left to right of the state data, 01 represents that the state of the vehicle oil tank is open, and 00 represents that the state of the vehicle oil tank is closed. It is understood that when the vehicle tank is open, the vehicle may be refueled or fail, and the vehicle should be controlled to shut down.
In one possible embodiment, if the vehicle fuel tank state is open, the determining the engine speed includes: sending a read command to an ECU of the engine in a case where a communication connection is established with the vehicle. And receiving state data returned by the engine, and judging the rotating speed of the engine according to the state data.
Specifically, in the present embodiment, the activation command is sent to the ECU of the engine at 0x22f 001. And the state data returned by the ECU receiving the engine is 0x62f00150, and the rotating speed of the engine is judged according to the rightmost two-digit data of the state data sorted from left to right. The rotating speed formula of the engine is as follows:
Y＝10*(X)10
wherein Y is the rotation speed of the engine, (X)10The decimal value of the two-bit data on the right side of the state data is 10, which is a coefficient in the present embodiment. In bookIn one example, the engine speed Y is 10 × 80 — 800 according to the engine speed formula.
Specifically, in order to prevent another program from accidentally controlling the engine stop, it is necessary to send a verification instruction to the ECU of the engine before controlling the engine stop. For example, after 0x2701 is transmitted to the ECU of the engine, 0x670111223344, which is security seed data returned by the ECU of the engine, is received. And calculating a corresponding security code 0x55667788 according to the security seed data. And when the safety code calculated according to the safety seed data is matched with the safety code 0x270255667788 of the ECU of the engine, receiving correct data 0x6202 returned by the ECU of the engine, and sending a stop command 0x3100ff08 to the ECU of the engine to control the engine to stop.
It can be understood that, in the present embodiment, the introduction of the safety seed data and the safety code prevents the engine from being stopped unexpectedly, so that the method for automatically shutting down the refueling vehicle has higher stability and safety, and ensures the life safety of the driver.
In one possible embodiment, determining the vehicle ignition status comprises: and sending a reading command to an ECU (electronic control Unit) igniting the vehicle under the condition of establishing communication connection with the vehicle. And receiving state data returned by the vehicle ignition, and judging the vehicle ignition state according to the state data.
