Embodiment 1
[0107] Embodiment 1: Upgrading the ECU software of the liquid crystal instrument and the ECU software of the body controller through the cloud server
[0108] The smart cockpit domain controller connects to the cloud service platform through the 4G network;
[0109] The cloud platform simultaneously pushes the request for upgrading the LCD instrument ECU software and the request for upgrading the body controller ECU software to the smart cockpit domain controller.
[0110] The smart cockpit domain controller receives and judges the upgrade request packet information;
[0111] When the request data packet is the liquid crystal instrument ECU of the smart cockpit domain controller, directly establish a data connection, receive and cache the upgrade data packet;
[0112] After the smart cockpit domain controller receives the LCD instrument ECU software upgrade package, it verifies the validity and version of the upgrade package. After the verification is passed and the upgrade c...
Embodiment 2
[0118] Embodiment 2: Upgrade the body controller ECU software through a U disk
[0119] Through the external USB interface of the smart cockpit domain controller, insert the U disk with the ECU software upgrade package of the body controller;
[0120] After the smart cockpit domain controller recognizes the upgrade package request, it judges the upgrade request data package information;
[0121] Judging that the upgrade request is the body controller ECU under the body system domain controller, it requests to update the path mapping table, obtains the shortest path nodes, establishes data connections for each node, and the smart cockpit domain controller reads and forwards the upgrade to the body system domain controller data pack;
[0122] Steps 5, 6, and 7 are the same as 8, 9, and 10 in Embodiment 1.
Embodiment 3
[0123] Embodiment 3: Receive the differential upgrade package through the CAN network of the cockpit domain controller, and upgrade the body controller ECU software to send an upgrade package transmission request to the CAN network of the cockpit domain controller through the CAN programming tool at the PC end;
[0124] The cockpit domain controller receives and judges the upgrade request packet information;
[0125] Judging that the upgrade request is the body controller ECU under the body system domain controller, it requests to update the path mapping table, obtains the shortest path nodes, establishes data connections for each node, and the smart cockpit domain controller reads and forwards the upgrade to the body system domain controller data pack;
[0126] The body system domain controller receives and buffers the data packet, and replies to receive the data frame;
[0127] After the body system domain controller receives the body controller ECU software upgrade package...
