Description

Technical Field

[0001] The present invention belongs to the technical field of automotive body control system dormancy, and particularly relates to a BCM forced dormancy method, system, electronic device and storage medium. Background Art

[0002] The application of electronic control units in automobiles is increasing, and data communication between various electronic devices is also increasing. At the same time, the widespread use of these independent control units has brought problems such as increased costs, high failure rates, and complex wiring, while reducing the driving experience and comfort of the vehicle. In view of this, as a control module with powerful design functions, the BCM realizes discrete controller functions and controls numerous electrical appliances, and has become the electrical core of the vehicle. Due to the large number of external conditions and control strategies involved, and the large number of new functions and new strategies in recent years, there are more or less omissions in the verification scenarios during the design process. When an abnormal scenario occurs, it may cause the entire vehicle not to enter dormancy, resulting in battery power depletion and ultimately the vehicle being unable to start.

[0003] Currently, the dormancy strategy of the BCM is as follows: after the vehicle is powered off, the BCM determines whether to enter the dormancy strategy and checks whether all sleep flags of the BCM itself are empty; if they are empty, the vehicle network management enters dormancy, and if not, it continues to check the sleep flags. When this flag cannot be cleared all the time, it will cause the BCM to be in an abnormal situation all the time, and the vehicle cannot enter dormancy, affecting the power consumption of the entire vehicle.

[0004] Therefore, how to design an effective forced dormancy strategy for the BCM in abnormal scenarios to solve the technical problem that the BCM does not enter dormancy in abnormal scenarios, resulting in the vehicle battery being depleted and unable to start, is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a BCM forced dormancy method, system, electronic device and storage medium. After the vehicle is powered off, when a sleep flag is detected, a forced dormancy strategy with a preset dormancy judgment condition is started for countdown. If the sleep flag still exists after the countdown exceeds the preset duration, dormancy is enforced to ensure that the entire vehicle does not fail to enter dormancy due to certain abnormal scenarios, resulting in battery power depletion.

[0070] Embodiment 1

[0071] This embodiment provides a method for forced BCM sleep. Figure 1 It is a flowchart of the method for forced BCM sleep according to the embodiment of this application. As Figure 1 shown, this process includes the following steps:

[0072] S101, when the vehicle is powered off, start a timeout counter with a preset timeout value set;

[0073] Specifically, in this embodiment, by setting a timeout counter, when the vehicle still has a sleep flag bit after exceeding the preset timeout value, the method for forced BCM sleep of this embodiment is started. Among them, the preset timeout value in the used timeout counter is set to 20 minutes.

[0074] S102, when at least one of the obtained sleep flag bits is not idle, determine whether the BCM is in the OTA mode;

[0075] Specifically, the sleep flag bit refers to the sleep flag bit of the CAN gateway. As the hub of the vehicle network, the gateway needs to forward and process relevant signals for each controller of the vehicle. Each CAN line and the controllers on it form a network segment, such as the power network segment, the body network segment, the audio-visual network segment, the chassis network segment, etc. The network segments are independent and communicate through the gateway. The sleep strategy of the network segment can follow the AUTOSAR network management mechanism, that is: under normal circumstances, when the controller itself meets the sleep condition, it will set its own sleep flag bit. After all controllers have set their own sleep flag bits, the last controller to set the bit will send a command to enter the sleep state on the bus. If there is no wake-up event within the waiting time, the network segment can enter the sleep state.

[0076] S103, if so, set the count value in the OTA countdown counter to the preset countdown value and start the OTA countdown counter, where the preset timeout value is less than the preset countdown value;

[0077] Specifically, the preset countdown value is greater than the default value of the OTA countdown counter of the vehicle itself. The purpose is to ensure that each software loaded on the vehicle can be upgraded normally before the BCM is forced to sleep if the vehicle is in the OTA mode.

[0078] S104, detect the IGN switch state, the PEPS power state, the in-vehicle network diagnosis state, the hazard warning light state, and the sleep flag bit state one by one, and determine whether any one of the IGN switch state, the PEPS power state, the in-vehicle network diagnosis state, the hazard warning light state, and the sleep flag bit state meets the preset requirements;

[0079] Specifically, the preset requirements mean that the IGN switch state is in the on state, the PEPS power state is in the on state, the in-vehicle network diagnosis state is in the running state, the hazard warning light state is in the on state, and the sleep flag bit state is in the switching state. In this embodiment, first, the IGN switch state is detected. If the IGN switch state is in the off state, the PEPS power state is detected continuously, otherwise, the next step is directly carried out; if the detected PEPS power state is in the off state, the in-vehicle network diagnosis state is detected continuously, otherwise, the next step is directly carried out. Similarly, the detection of the hazard warning light state and the sleep flag bit state is carried out in turn.

[0080] S105, if not, determine whether the value in the timeout counter reaches the preset timeout value and whether the value in the OTA countdown counter is zero;

[0081] Specifically, through the dual comparison of the values in the timeout counter and the OTA countdown counter with the preset values, the technical problem of the vehicle's battery being drained due to the vehicle not going into sleep due to certain abnormal scenarios is solved.

[0082] S106, if so, perform forced sleep processing on the BCM.

[0083] In summary, after the vehicle is powered off, start the timeout counter with a preset timeout value set. When the BCM is in the OTA mode, set a preset countdown value greater than the default value of the vehicle's own OTA countdown counter in the OTA countdown counter and then start it. Detect the IGN switch status, PEPS power status, in-vehicle network diagnosis status, hazard warning light status, and sleep flag status one by one. If any one of the statuses does not meet the preset requirements, and it is determined that the value in the timeout counter reaches the preset timeout value and the value in the OTA countdown counter is zero, perform forced sleep on the BCM.

[0089] A first detection module 104, configured to detect the IGN switch status, PEPS power status, in-vehicle network diagnosis status, hazard warning light status, and sleep flag status one by one, and judge whether any one of the IGN switch status, the PEPS power status, the in-vehicle network diagnosis status, the hazard warning light status, and the sleep flag status meets the preset requirements;

[0090] The second judgment module 105 is configured to, if it is determined that any one of the IGN switch state, the PEPS power supply state, the in-vehicle network diagnosis state, the hazard warning light state, and the sleep flag bit state does not meet the preset requirements, determine whether the value in the timeout counter reaches the preset timeout value and whether the value in the OTA countdown counter is zero;

[0091] The first processing module 106 is configured to, if it is determined that the value in the timeout counter reaches the preset timeout value and the value in the OTA countdown counter is zero, perform forced sleep processing on the BCM.

[0092] It should be noted that the above-mentioned each module can be a functional module or a program module, and can be implemented either by software or by hardware. For the modules implemented by hardware, the above-mentioned each module can be located in the same processor; or the above-mentioned each module can also be located in different processors in any combination form.

[0093] Embodiment III

[0094] This embodiment provides a method for forcibly sleeping the BCM. Figure 3 It is a flowchart of the method for forcibly sleeping the BCM according to the embodiment of the present application, as Figure 3 shown, and the process includes the following steps:

[0095] S201. When the vehicle is powered off, start a timeout counter with a preset timeout value;

[0096] S202. When at least one of the obtained sleep flag bits is not idle, determine whether the BCM is in the OTA mode;

[0097] S203. If not, perform one-by-one detection on the IGN switch state, the PEPS power supply state, the in-vehicle network diagnosis state, the hazard warning light state, and the sleep flag bit state, and determine whether any one of the IGN switch state, the PEPS power supply state, the in-vehicle network diagnosis state, the hazard warning light state, and the sleep flag bit state meets the preset requirements;

[0098] S204. If not, determine whether the value in the timeout counter reaches the preset timeout value;

[0099] S205. If so, perform forced sleep processing on the BCM.

[0100] In summary, after the vehicle is powered off, an overtime counter with a preset overtime value is started. When the BCM is not in the OTA mode, a preset countdown value greater than the default value of the vehicle's own OTA countdown counter is set for the OTA countdown counter and then started. The IGN switch status, the PEPS power status, the in-vehicle network diagnosis status, the hazard warning light status, and the sleep flag status are detected one by one. If any one of the statuses does not meet the preset requirements and it is determined that the value in the overtime counter reaches the preset overtime value, the BCM is forced to enter the sleep state.

[0117] In summary, after the vehicle is powered off, turn on the timeout counter with a preset timeout value set. When the BCM is in the OTA mode, set a preset countdown value greater than the default value of the vehicle's own OTA countdown counter and then start it. Detect one by one the IGN switch state, the PEPS power state, the in-vehicle network diagnosis state, the hazard warning light state, and the sleep flag bit state. If any one of the states does not meet the preset requirements and it is determined that the value in the timeout counter does not reach the preset timeout value, do not perform the forced sleep for the BCM.
