Abstract

The invention discloses a new energy automobile vehicle controller connection structure. The new energy automobile vehicle controller connection structure comprises a vehicle controller. The vehicle controller comprises a power interface, a digital quantity collection interface, an analog quantity collection interface, a CAN communication interface, a driving interface and a power output interface. The new energy automobile vehicle controller connection structure has the advantages that when working, the controller collects a digital signal of a finished automobile through the digital quantity collection interface, the analog quantity collection interface collects an analog quantity signal of the finished automobile, and meanwhile, the controller communicates with other components of the finished automobile through a CAN communication network. Based on the above signals, the driving intention of a driver is analyzed in real time, and the vehicle controller which is high in operational capability, stable and reliable is achieved.

Description

technical field [0001] The invention relates to the field of new energy vehicle control. Specifically, a vehicle controller using a floating point operation chip is designed. Background technique [0002] New energy vehicles mainly include pure electric vehicles, hybrid vehicles, fuel cell vehicles and extended-range vehicles. As the core component of new energy vehicles, the vehicle controller has higher requirements on the performance and functions of the vehicle controller due to the increasingly rich configuration of new energy vehicles. It must meet the huge number of analog and digital signal processing, CAN The needs of communication and complex computing processing require a high-performance vehicle controller with strong computing power, fast computing speed, and strong driving capability. However, the current vehicle controller circuit layout and connection are difficult to meet the growing needs of new energy vehicles. Contents of the invention [0003] The t...
