Abstract

The invention relates to an intelligent environment-friendly automobile structure which pertains to the technical fields of new energy and intelligent automobile design and comprises an automobile shell, wheels, facilities in a carriage, a vehicle sensing system, a power system, a transmission system, a brake system, a steering system and a vehicle control system; the vehicle sensing system is a system for sensing the external environment and vehicle attitudes, wherein, the system for sensing the external environment and the vehicle attitudes, the vehicle control system, the steering system, the brake system, the transmission system and the power system are respectively connected with a vehicle CAN bus; the automobile structure can greatly improve the response characteristics of the systems in operation and systematically increase the performance of the whole automobile, carry out the expected state recognition and trajectory planning of an automobile and further improve fuel economical property and emission performance under the operation of a driver. Due to the coordination and integrated control of all the systems, the whole automobile achieves the optimal systematical economical property, emission performance, safety and comfort.

Description

Technical field [0001] The invention belongs to the technical field of new energy and intelligent automobile design, and particularly relates to an intelligent environment-friendly automobile structure. Background technique [0002] With the increasingly prominent global energy and environmental issues, new energy vehicles with low emissions and low energy consumption have become a hot spot for research and development in the world's automotive industry. At present, the new energy vehicles that have been developed mainly include various electric vehicles and alternative fuel vehicles. Electric vehicles including pure electric vehicles, hybrid electric vehicles and fuel cell electric vehicles have become the research hotspot of international new energy vehicles. [0003] Fuel cell vehicles convert hydrogen into electricity, drive motors, and further drive vehicles. In order to extend the life of fuel cell engines, batteries are generally required for power balance and assistance t...
