BCM forced dormancy method, system, electronic equipment and storage medium

Technical Field

The invention belongs to the technical field of dormancy of an automobile body control system, and particularly relates to a BCM forced dormancy method, a system, electronic equipment and a storage medium.

Background

Electronic control units are increasingly used in automobiles, and data communication between various electronic devices is also increasing. Meanwhile, the wide use of the independent control units brings problems of cost increase, high failure rate, complex wiring and the like, and simultaneously reduces the experience and comfort of the automobile. In view of this, the BCM has become an electrical core of a vehicle as a control module with a powerful design function, which realizes a discrete controller function and controls a plurality of electrical appliances. Because the external conditions and the control strategies are more, and new functions and new strategies in recent years are more, the scenes verified in the design process are careless, and when some abnormal scene occurs, the whole vehicle may not sleep, the storage battery feeds electricity, and finally the vehicle cannot be started.

Currently, the sleep strategy of BCM is: after the vehicle is powered off, the BCM determines to enter a sleep strategy, and detects whether all sleep flag bits of the BCM are empty; if the power consumption of the whole vehicle is not reduced, the BCM is always in an abnormal condition, and the power consumption of the whole vehicle is influenced because the whole vehicle cannot sleep.

Example one

The embodiment provides a BCM forced dormancy method. Fig. 1 is a flowchart of a BCM forced sleep method according to an embodiment of the present application, as shown in fig. 1, the flowchart includes the following steps:

s101, when a vehicle is powered off, starting a timeout counter with a preset timeout value;

specifically, in the present embodiment, by setting a timeout counter, when the vehicle still has a sleep flag bit after exceeding a preset timeout value, the BCM forced hibernation method of the present embodiment is started. Wherein the preset timeout value in the adopted timeout counter is set to be 20 minutes.

S102, when at least one acquired sleep flag bit is not idle, judging whether the BCM is in an OTA mode or not;

specifically, the sleep zone bit refers to a sleep zone bit of a CAN gateway, the gateway is used as a hub of a whole vehicle network, all controllers of the whole vehicle need to forward and process related signals through the gateway, each CAN line and the controllers on the CAN line form a network segment, such as a power network segment, a vehicle body network segment, a video network segment, a chassis network segment and the like, and the network segments are independent and are connected and communicated through the gateway. The dormancy policy of a network segment may follow the AUTOSAR network management mechanism, namely: under normal conditions, when the controller meets the sleep condition, the controller sets the sleep zone bit, after all the controllers set the sleep zone bit, the last set controller sends a command of entering the sleep state to the bus, and if no wake-up event exists in the waiting time, the network segment can enter the sleep state.

S103, if yes, setting a count value in an OTA countdown counter as a preset countdown value, and starting the OTA countdown counter, wherein the preset timeout value is smaller than the preset countdown value;

specifically, the preset countdown value is greater than a default value of the OTA countdown counter of the vehicle, and the purpose is to ensure that each piece of software loaded on the vehicle can be normally upgraded before the BCM is forced to sleep if the vehicle is in the OTA mode.

S104, detecting an IGN switch state, a PEPS power supply state, a vehicle-mounted network diagnosis state, a dangerous warning lamp state and a sleep flag state one by one, and judging whether any one of the IGN switch state, the PEPS power supply state, the vehicle-mounted network diagnosis state, the dangerous warning lamp state and the sleep flag state meets preset requirements;

specifically, the preset requirements indicate that the IGN switch state is in an on state, the PEPS power state is in an on state, the vehicle-mounted network diagnosis state is in an operating state, the hazard warning lamp state is in an on state, and the sleep flag state is in a switching state. In the embodiment, the state of the IGN switch is detected firstly, if the state of the IGN switch is in a closed state, the state of the PEPS power supply is detected continuously, otherwise, the next step is directly performed; and if the state of the PEPS power supply is detected to be in a closed state, the vehicle-mounted network diagnosis state is continuously detected, otherwise, the next step is directly carried out, and the detection of the state of the dangerous warning lamp and the state of the sleep zone bit is analogized in sequence and the same manner.

S105, if not, judging whether the numerical value in the timeout counter reaches the preset timeout value or not, and whether the numerical value in the OTA countdown counter is zero or not;

specifically, the technical problem that the storage battery feeding condition occurs due to the fact that the whole vehicle is not dormant in some abnormal scenes is solved through double comparison of the numerical value in the overtime counter and the OTA countdown timer with a preset value.

And S106, if yes, executing forced dormancy processing aiming at the BCM.

In summary, after the vehicle is powered off, the timeout counter with the preset timeout value is started, when the BCM is in the OTA mode, the OTA countdown counter is set with the preset timeout value larger than the default value of the vehicle OTA countdown counter and then started, the IGN switch state, the PEPS power state, the vehicle network diagnosis state, the hazard warning lamp state and the sleep flag bit state are detected one by one, any one of the states does not meet the preset requirement, and forced dormancy of the BCM is executed under the condition that the value in the timeout counter reaches the preset timeout value and the value in the OTA countdown counter is zero.
