8. The engine system of claim 1, wherein the upgrade decision module upgrades the head end OTA of the vehicle according to the upgrade decision, comprising:
and packaging the upgrade decision to generate an upgrade package so as to upgrade the vehicle-end OTA based on the upgrade package.
9. The engine system of claim 1, wherein the upgrade decision module upgrades the head end OTA of the vehicle according to the upgrade decision, further comprising:
before upgrading the vehicle-end OTA of the vehicle according to the upgrading decision, acquiring the identity information of the vehicle, and verifying the identity information of the vehicle to confirm whether the vehicle is legal or not;
if the upgrade decision is legal, sending the upgrade decision to a user for confirmation, if a confirmation command of the user is received, downloading an upgrade package according to the confirmation command, and executing the upgrade of the vehicle-end OTA according to the downloaded upgrade package;
if the confirmation command comprises the upgrade starting time required by the user, determining whether the upgrade starting time required by the user meets the upgrade requirement, if so, modifying an upgrade decision according to the upgrade starting time required by the user, reconstructing an upgrade package according to the modified upgrade decision, downloading the reconstructed upgrade package, starting with the upgrade starting time required by the user, and executing the upgrade of the vehicle-end OTA according to the reconstructed upgrade package;
signing the generated upgrade package or the reconstructed upgrade package before the upgrade of the vehicle-end OTA is executed, checking the label of the downloaded upgrade package or the reconstructed upgrade package after the upgrade package or the reconstructed upgrade package is downloaded, and executing the upgrade of the vehicle-end OTA according to the downloaded upgrade package or the reconstructed upgrade package if the label checking is successful.
10. An engine method for vehicle-side OTA upgrades, the method comprising:
after receiving a vehicle-end OTA upgrading request of a user, monitoring the state of a vehicle and the environment state of the vehicle in real time, and detecting the network state of the vehicle;
determining the health state of the current vehicle according to the vehicle state data, the environment state data of the vehicle and the vehicle network state data;
and calling the determined health state of the vehicle, generating an upgrade decision according to the health state, and upgrading the OTA of the vehicle according to the upgrade decision.
