For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] The embodiment of the present invention provides a vehicle power supply management method, combining Figure 1 As shown in the flowchart, the power supply management method includes steps 101 to 103:

[0041] Step 101: receiving a request device ID sent by a target functional domain;

[0042] In this embodiment, the present invention provides a vehicle power supply management method based on SOA architecture. The architecture provides a preset network power supply relationship table (also called PowerMap&NetworkMap), network management controller specifications, and vehicle power supply management requirements. Among them, the network management controller specifications include specific specifications for the on-demand sleep / wake-up of each electronic control unit in the vehicle, and are specification guidelines for each target functional domain to request the vehicle power supply management module to wake up / sleep and power on / off on demand. The vehicle power supply management requirements include the requirements for the implementation of specific vehicle power supply management functions, which can be used as a guide for the development of vehicle power supply management software under the PN architecture.

[0043] Among them, the target functional domain sends the request device ID to the vehicle power supply management module by calling the target interface. And only the target functional domain can call the target interface to send the request device ID. The target functional domain is determined from the functional domains of the vehicle. In order to standardize each functional domain, this embodiment sets a unique target ID for each target functional domain to distinguish it, so as to avoid other functional domains mistakenly calling the target interface to power on and off. For example:

[0044] 0x0: Clientid_BCM, refers to the target ID of the body controller;

[0045] 0x1: Clientid_AC, refers to the target ID of the compressor;

[0046] 0x2: Clientid_VCU, which refers to the target ID of the vehicle controller;

[0047] 0xA: Clientid_VMM, which refers to the target ID of vehicle mode management;

[0048] In this embodiment, the requesting device ID refers to the ID of the requesting device to be controlled by the target functional domain. Each requesting device corresponds to a unique requesting device ID.

[0049] Step 102: According to the requesting device ID, based on a preset network power supply relationship table, determine the device wake-up attribute of the requesting device and the device wake-up information corresponding to the device wake-up attribute; the network power supply relationship table includes a target device ID and a target wake-up attribute and target attribute information corresponding to the target device ID;

[0050] In this embodiment, the network power supply relationship table is set based on the requesting device of the target functional domain. The target device ID in the network power supply relationship table covers the IDs of all devices to be controlled by the target functional domain. In other words, the requesting device ID sent by the target functional domain can find the corresponding target device ID in the network power supply relationship table. The specific steps of the search may include:

[0051] Searching in a preset network power supply relationship table, if there is a target device ID that is the same as the request device ID, taking the target wake-up attribute corresponding to the target device ID as the device wake-up attribute;

[0052] The target attribute information corresponding to the target wake-up attribute is used as device attribute information.

[0053] The device wake-up attribute refers to the wake-up type of the requesting device. The types of wake-up attributes include network wake-up attribute and power distribution wake-up attribute. It should be noted that for a requesting device, its device wake-up attribute may include a network wake-up attribute, or include a power distribution wake-up attribute, or include both network wake-up attribute and power distribution wake-up attribute.

[0054] Different types of device wake-up attributes correspond to different device wake-up information.

[0055] In one embodiment, if the device wake-up attribute includes a power distribution wake-up attribute, the device attribute information includes an insurance ID and a device area control unit corresponding to the insurance ID;

[0056] In one embodiment, if the device wake-up attribute includes a network wake-up attribute, the device attribute information includes a device gateway area control unit and a device network segment to which the requesting device belongs;

[0057] In one embodiment, if the device wake-up attribute includes a power distribution wake-up attribute and a network wake-up attribute, the device attribute information includes an insurance ID, a device area control unit corresponding to the insurance ID, a device gateway area control unit, and the device network segment.

[0058] The insurance ID refers to the ID of the insurance associated with the requesting device.

[0059] Step 103: Perform power supply management on the regional control unit corresponding to the requesting device according to the device wake-up attribute of the requesting device and the device wake-up information.

[0060] In this embodiment, after the device wake-up attribute and the device wake-up information of the requesting device are determined, the device that needs to be awakened / sleeped for the management requesting device is determined.

[0061] If the device wake-up attribute corresponding to the requesting device includes the power distribution wake-up attribute based on the network power supply relationship table, the network management module is requested to wake up / sleep the device area control unit, and the device area control unit is requested to power on / off the insurance ID.

[0062] If it is analyzed based on the network power supply relationship table that the device wake-up attribute corresponding to the requesting device includes a network wake-up attribute, the network management module is requested to wake up / sleep the corresponding device gateway area control unit and the device network segment to which the requesting device belongs.

[0063] If it is analyzed based on the network power supply relationship table that the device wake-up attributes corresponding to the requested device include power distribution wake-up attributes and network wake-up attributes, the network management module is requested to wake up / sleep the device area control unit, and the device area control unit is requested to power on / off the insurance ID; at the same time, the network management module is requested to wake up / sleep the corresponding device gateway area control unit and the device network segment to which the requested device belongs.

[0064] In order to facilitate understanding and implementation by those skilled in the art, this embodiment is described by way of example:

[0065] The BCM body controller serves as the target functional domain and calls the target interface to send a request device ID "0x02B" to the vehicle power supply management module. The vehicle power supply management module searches the network power supply relationship table and determines that the request device is a steering wheel heating device. The device wake-up attribute of the request device is a power distribution wake-up attribute. At the same time, the device wake-up information is determined as follows: the PN bit of the device area control unit VIU-ML is set. A PN bit of 1 indicates that the device is requested to be awakened, and a PN bit of 0 indicates that the device is requested to sleep. At the same time, power is supplied to the insurance ID "0x0188".

[0066] The BCM body controller is the target functional domain, and calls the target interface to send the request device ID "0x745" to the vehicle power management module. The vehicle power management module searches the network power relationship table and determines that the request device is the left front door module, and the device wake-up attributes of the request device are the power distribution wake-up attribute and the network wake-up attribute. At the same time, the device wake-up information is determined as follows: set the PN bit of the device area control unit VIU-ML; at the same time, power is supplied to the insurance ID "0x0172"; set the PN bit of the device gateway area control unit VIU-ML, and set the device network segment BodyCAN1. Among them, the PN bit is 1, which means that the device is requested to wake up, and the PN is 0, which means that the device is requested to sleep.

[0067] It should be noted that after the network management module receives the request from the vehicle power supply management module, it will set / clear the network wake-up flag of each gateway segment on the Backbone network, realize the on-demand wake-up of the regional control unit of each segment, and maximize the energy consumption of the entire vehicle.

[0068] In summary, the embodiment of this specification provides a vehicle power supply management method, which receives the request device ID sent by the target functional domain; according to the request device ID, based on the preset network power supply relationship table, determines the device wake-up attribute of the request device and the device wake-up information corresponding to the device wake-up attribute; the network power supply relationship table includes the target device ID and the target wake-up attribute and target attribute information corresponding to the target device ID; according to the device wake-up attribute of the request device and the device wake-up information, performs power supply management on the regional control unit corresponding to the request device. In this way, the whole vehicle's electronic control unit can be powered on demand, and the energy consumption of the whole vehicle can be reduced while ensuring the normal operation of the whole vehicle's electronic control unit.
