Referring to fig. 1, fig. 1 is a flowchart of a vehicle fault diagnosis method according to an embodiment of the present invention, as shown in fig. 1, including the following steps:
And 102, receiving and responding to a vehicle diagnosis instruction sent by a diagnosis instrument connected with the target interface.
The preset activation condition comprises a first activation condition or a second activation condition, the first activation condition is used for activating the first interface, the second activation condition is used for activating the second interface, the first activation condition is that the second interface is detected to be deactivated, the second activation condition is that an activation request of the second interface is received when the first interface is in an activation state, and the continuous diagnosis time of a diagnosis instrument connected with the first interface reaches a preset time length.
In the embodiment of the invention, the vehicle fault diagnosis method can be applied to a scene that a plurality of diagnostic instruments are connected with different interfaces of the automobile gateway to perform fault diagnosis on the same vehicle, for example, the vehicle-mounted diagnostic instrument and the vehicle external diagnostic instrument are connected with different interfaces of the automobile gateway to perform fault diagnosis on the vehicle. In order to avoid fault diagnosis conflicts, only one of the diagnostic apparatuses may be allowed to diagnose the vehicle at the same time, that is, only one of the interfaces of the automotive gateway, which is connected with the diagnostic apparatus, is activated, and the vehicle diagnosis command sent by the diagnostic apparatus is received through the interface.
In the embodiment of the invention, different activation conditions can be preset to switch the activation states of different interfaces of the automobile gateway, so that different diagnostic instruments can be switched to diagnose the automobile, wherein the different activation conditions can be used for activating different automobile gateway interfaces.
Therefore, in this step, when a preset activation condition is satisfied, the target interface corresponding to the preset activation condition may be controlled to be in an activated state, and accordingly, the interfaces other than the target interface in the interfaces of the automobile gateway are in a deactivated state, that is, only the target interface is activated at the current time. In this way, the automobile gateway can receive a vehicle diagnosis instruction sent by the diagnosis instrument connected with the target interface through the target interface, transmit the vehicle diagnosis instruction to the vehicle controller to execute the vehicle diagnosis instruction, and perform fault diagnosis on the vehicle according to the vehicle diagnosis instruction.
The preset activation condition may include a first activation condition or a second activation condition, where the first activation condition is used to activate a first interface of the car gateway, and the second activation condition is used to activate a second interface of the car gateway, that is, when the second interface is in an activation state, if the first activation condition is met, the preset activation condition may jump to the activation state of the first interface, so as to diagnose a vehicle by using a diagnostic instrument connected to the first interface, and when the first interface is in an activation state, the preset activation condition may jump to the activation state of the second interface, so as to diagnose the vehicle by using the diagnostic instrument connected to the second interface.
The first activation condition is detection of deactivation of the second interface, such as detection of disconnection of a diagnostic instrument connected to the second interface from the second interface, detection of prohibition of use of the second interface, or the like. The second activation condition is that an activation request of the second interface is received when the first interface is in an activation state, and the continuous diagnosis time of the diagnosis instrument connected with the first interface reaches a preset time length, wherein the received activation request of the second interface can be that the second interface is detected to be connected with the diagnosis instrument and a request connection instruction sent by the diagnosis instrument is received, and the continuous diagnosis time of the diagnosis instrument connected with the first interface reaches the preset time length, which can be that the automobile gateway receives and responds to the vehicle diagnosis instruction sent by the diagnosis instrument connected with the first interface after the automobile gateway has continuously reached the preset time length; specifically, it is determined whether the duration of the diagnosis time of the first interface-connected diagnostic apparatus reaches a preset time, where the time may be determined by starting a timer to time a current task or by timing the task when starting to receive a vehicle diagnosis instruction sent by the first interface-connected diagnostic apparatus; the duration diagnosis time of the diagnosis instrument connected with the first interface reaches a preset time length, which can be understood as that the event for diagnosing the vehicle by the diagnosis instrument connected with the first interface is finished, so that the preset time length can be determined according to the diagnosis time length required by the diagnosis instrument.

In this embodiment, a default activated car gateway interface may be preset to default to an activated state of the interface when a vehicle is powered on, and specifically, since a CAN bus of the car gateway has the characteristics of simplicity and reliability and is usually connected to a vehicle-mounted diagnostic apparatus, the car gateway may default to the activated state of the CAN bus interface when the vehicle is powered on to ensure that the vehicle-mounted diagnostic apparatus has a higher diagnostic priority, and when the vehicle-mounted diagnostic apparatus sends a first vehicle diagnostic instruction through the CAN bus interface, the car gateway may receive and respond to the first vehicle diagnostic instruction.
Since the vehicle-mounted diagnostic apparatus is connected to the vehicle gateway through the CAN bus interface and the vehicle-mounted ethernet interface T1, different activation conditions may be set to switch the activation states of the CAN bus interface and the vehicle-mounted ethernet interface T1, respectively, in order to avoid collision of diagnostic instructions sent by the CAN bus interface and the vehicle-mounted ethernet interface T1.
Specifically, the method may jump from the activation state of the CAN bus interface to the activation state of the vehicle ethernet interface T1 to receive and respond to the second vehicle diagnosis instruction sent by the vehicle diagnosis apparatus when a third activation condition is met, where the third activation condition may be that a routine activation request of the vehicle diagnosis apparatus is received, and a duration diagnosis time of the vehicle diagnosis apparatus through the CAN bus interface reaches a preset time.

condition 1: the end of the transport layer transmission or the transport layer transmission time is exhausted;
condition 2: the gateway receives a diagnosis message of any CAN node from the HMI;
condition 3: the gateway receives a routine activating request of the HMI through the DoIP;
condition 4: the timer T runs out;
condition 5: target PIN (e.g., PIN8 in FIG. 4) enable;
condition 6: the target pin is not enabled;
action 1: a timer T is started.
Thus, after the vehicle is powered on, the vehicle defaults to enter the activation state of the ECAN bus interface;
when the automobile gateway simultaneously meets two conditions of 'receiving a routine activation request of an HMI through DoIP' and 'exhausting time of a timer T', the automobile gateway jumps to the activation state of a vehicle-mounted Ethernet interface T1 when being in the activation state of an ECAN bus interface;
when the vehicle gateway is in an activated state of the vehicle-mounted Ethernet interface T1, when two conditions of 'receiving a diagnosis message of any CAN node from the HMI' and 'transmission layer transmission is finished or transmission layer transmission time is exhausted' are simultaneously met, the vehicle gateway jumps to the activated state of the ECAN bus interface and starts a timer T; when the target PIN (e.g., PIN8 in fig. 4) is enabled, jumping to the active state of industrial ethernet interface TX;
when the ECAN bus interface is in an activated state, when the automobile gateway simultaneously meets two conditions of target pin enabling and timer T time exhaustion, jumping to the activated state of an industrial Ethernet interface TX, and starting to implement an external diagnosis function through an external diagnosis instrument;
and when the target pin is not enabled, jumping to the active state of the ECAN bus interface and starting a timer T.
When multiple diagnosis systems coexist, through clear conditions and action setting, each interface of the automobile gateway can carry out state transition according to a preset state, coordinate related signal actions and complete specific diagnosis operation, diagnosis and Bootloader failure can be greatly reduced, and therefore safety of whole automobile software is guaranteed and safety of the whole automobile is improved.
