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). Each protocol type has corresponding communication parameters and commands. For example, when the protocol type of the vehicle is CAN, communication pins of an Electronic Control Unit (ECU) of the vehicle are 6 and 14, a baud rate is 500K, and a VIN code reading command is 0x0807df 0209020000000000. According to the VIN code returned by the vehicle, the specific vehicle type can be analyzed.
In one possible embodiment, the determining the fuel tank state of the vehicle includes: and sending an activation command to an ECU of the vehicle oil tank under the condition of establishing communication connection with the vehicle. And receiving an activation success command returned by the ECU of the vehicle oil tank. Sending a read command to an ECU of the vehicle fuel tank. And receiving state data returned by the vehicle oil tank, and judging the state of the vehicle oil tank according to the state data.
Specifically, in the present embodiment, the activation command sent to the ECU of the vehicle fuel tank is 0x1001, and the return of the ECU of the vehicle fuel tank to 0x5001 indicates that the activation is successful. 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) 10 The 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 this example, the engine speed Y is 10 × 80 — 800, which can be derived from 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.
Specifically, in the present embodiment, the read command sent to the ECU that ignites the vehicle is 0x 222001. And receiving state data 0x62200103 returned by the ECU for vehicle ignition, and judging the vehicle ignition state according to the rightmost two-digit data of the state data sorted from left to right. For example, 03 represents ignition, 02 represents standby, and 01 represents flameout.
Specifically, in the present embodiment, when the vehicle ignition state is ignition or standby, the key-off command 0x3100ff0a is sent to the vehicle ignition chip, and after the vehicle is controlled to be turned off, the key-off success command 0x7100ff0a returned by the vehicle ignition chip is received, which indicates that the vehicle has been turned off.
