when the whole vehicle is in a non-aerial upgrading mode and the whole vehicle is not electrified, judging whether a whole vehicle network is dormant or not, if not, acquiring whole vehicle network communication data, judging whether an ECU (Electronic Control Unit) sends data under the condition that the network communication condition is not met or not according to the whole vehicle network communication data, and if so, judging that the ECU sending the data under the condition that the network communication condition is not met is a fault ECU;
the whole vehicle network communication data comprises a network management message, vehicle state data and a network awakening source signal.
Here, whether the whole vehicle is in the air upgrading mode can be judged through an air upgrading mode signal sent by an ECU in the vehicle. When a Controller Area Network (CAN) bus connected to a finished automobile gateway is dormant, the finished automobile Network is judged to be dormant, and when the CAN bus is dormant, a CAN Controller connected with the CAN bus knows the dormant state of the CAN bus.
Further, whether the ECU sends data under the condition that the network communication condition is not met is judged according to the network communication data of the whole vehicle, if yes, the ECU sending the data under the condition that the network communication condition is not met is a fault ECU, and the method specifically comprises the following steps:
judging whether an ECU which does not receive the data request instruction first and then sends data exists according to the network management message, if so, judging whether the ECU which does not receive the data request instruction first and then sends data belongs to an ECU of a network awakening source according to a signal of the network awakening source, if not, judging whether the ECU which does not receive the data request instruction first and then sends data belongs to the ECU of the network awakening source, if so, judging whether the ECU of the network awakening source which does not meet the data sending trigger condition and then sends data exists according to vehicle state data, and if so, judging that the ECU of the network awakening source which does not meet the data sending trigger condition and then sends data belongs to the ECU of the network awakening source.
The network awakening source signal comprises a brake state signal, a remote key remote control instruction signal and a vehicle door state signal, and the network awakening source ECU comprises a brake control ECU, a remote key control ECU and a vehicle door control ECU.
Judging whether the whole vehicle network is dormant specifically as follows: judging whether the finished automobile gateway is in a state of receiving or sending network data, if so, judging that the finished automobile network is in a non-dormant state, otherwise, judging that the finished automobile network is in a dormant state;
acquiring network communication data of the whole vehicle, specifically: the vehicle-mounted communication terminal acquires network communication data of the whole vehicle through the gateway of the whole vehicle.
The above-mentioned steps of determining the faulty ECU can be executed by a T-BOX (Telematics BOX, which is called a vehicle-mounted communication terminal for short).
For example, as shown in fig. 2, when the T-box determines that the entire vehicle is in a non-air upgrade mode and the entire vehicle is not under high voltage, and when the power source gear of the entire vehicle is shifted from a non-power-OFF gear (ON, ACC, CRANK, etc.) to a power-OFF gear (OFF gear) or the entire vehicle is powered OFF and the entire vehicle network is in sleep, the T-box wakes up, the timer is started, during the operation of the entire vehicle gateway, it is determined whether the entire vehicle network is in sleep, if the entire vehicle network is in sleep and the timing time of the T-veoffnetwakeaccurum is less than a preset time threshold, the bus is in sleep, the timer is cancelled, if the entire vehicle network is not in sleep and the timing time of the T-offnetwakeaccurum is greater than the preset time threshold, the T-box sends a recording trigger instruction to the T-box, and starts to collect instruction data. And the T-box determines the faulty ECU and the fault reason thereof according to the instruction data. The instruction data comprises a network management message of the network management ECU, vehicle state data and a network awakening source correlation signal. The vehicle state data includes power state, door opening state, position information, current time and other data of the whole vehicle.
The method avoids the false triggering of the timer under the normal operation condition that a user needs to wake up the network for a long time (the working condition duration is greater than a preset time threshold, such as air upgrading and the like) through two conditions of a non-air upgrading mode and a condition that the whole vehicle is not provided with high pressure. The timing of the timer is cancelled through the condition of all-network dormancy, the time length accumulation of short-time awakening such as T-box remote control is specified, and the time length accumulation of short-time operation of a vehicle by a user is avoided, so that the false triggering of the timing of the timer is avoided.
The finished automobile fault identification method also comprises the following steps:
the Vehicle-mounted communication terminal acquires Vehicle network communication data through a Vehicle gateway, acquires a Vehicle VIN (Vehicle Identification Number) code and uploads the Vehicle VIN code and the Vehicle network communication data to the background server;
the background server determines vehicle configuration parameters according to the vehicle VIN codes, judges whether the ECU sends data under the condition that the network communication conditions are not met or not according to the vehicle configuration parameters and the whole vehicle network communication data, and if the ECU sends the data under the condition that the network communication conditions are not met, the ECU sending the data is a fault ECU.
The background server can perform troubleshooting and power shortage quality problem data analysis according to the vehicle VIN code and the whole vehicle network communication data.
Specifically, for example, the vehicle communication data collected by the background server includes network management messages, and the background server performs judgment according to the network management messages, and in the network management messages, when a certain ECU actively wakes up the network, the network management messages occur, the ECU is locked as a faulty ECU, and meanwhile, if the throttle state signal is on, the vehicle throttle state is locked as on, which is a reason for the vehicle network to continuously wake up.
The background server positions a reference basis of a fault ECU and a fault reason, data acquisition is from the function design of the whole vehicle, the fault ECU is preliminarily determined through a network management message of the ECU, and then the specific reason of the fault is further determined through a network awakening source correlation signal of the fault ECU.
