Problems solved by technology
Therefore, the integration of ordinary hybrid electric vehicles increases the load on the hybrid electric vehicle controller and increases the difficulty of integration. Its integration performance and response speed are limited, so that the vehicle cannot respond in a timely manner under certain sudden failures that require rapid response. Response, consequences and impact unimaginable

The invention provides an integrated system for a complete automobile, and a failure handling method of the integrated system. The integrated system for the complete automobile comprises microcontrollers and a communication network, wherein the communication network comprises a first CAN (Controller Area Network) bus, a second CAN bus and a third CAN bus. According to the integrated system, the CAN buses adopt three different rates; the CAN buses adopting different rates are accessed according to real-time requirements of the microcontrollers in the complete automobile; and the bus utilization ratio can be increased reasonably while the bus load is reduced. The failure handling method decides whether failures of the microcontrollers are to be reported to a hybrid complete automobile controller according to grades of the failures, so that the load of the hybrid complete automobile controller is reduced, and the response speed of the hybrid complete automobile controller is increased. In addition, the microcontrollers have corresponding failure protection policies for the complete automobile and handle the failures timely, the disadvantage that the complete automobile controller conducts failure protection on the complete automobile is avoided, the complete automobile controller only conducts the failure protection when fatal or serious failures happen, and the safety of the complete automobile is improved.
Description
technical field [0001] The invention relates to a whole vehicle integration system and a fault handling method thereof, in particular to a whole vehicle integration system used on a hybrid electric vehicle and a fault handling method thereof. Background technique [0002] With the continuous improvement of automobile automation and intelligent requirements, the electrical components and micro-control systems required in the vehicle are also increasing, which poses a challenge to the performance of the integrated control of the vehicle, especially for the current development of hot hybrid vehicles. In other words, the increase of its new energy system also brings the difficulty of system integration such as corresponding control and fault protection. [0003] At present, for ordinary hybrid electric vehicles, the integration of the vehicle system is mainly reflected in the integration of the functions of the hybrid vehicle controller (HCU). Specifically, the hybrid vehicle co...
