An electric vehicle intelligent vehicle controller

Abstract

The invention provides an intelligent controller for a whole electric car. The intelligent controller comprises a microcontroller module, a data processing module, a power driving module and a power source module. The intelligent controller further comprises an external information storage module which is used for recording related information and fault information of a control system for the whole electric car. The information storage module is electrically connected with the microcontroller. The intelligent controller further comprises a communication interface module and a wireless 3G module, wherein the communication interface module comprises two controller area network (CAN) buses, a key word protocol (KWP) bus and an RS232 bus. As a wireless module is arranged, uploading of data does not have access to the power bus CAN passively, and interference caused by data access is avoided. Communication cables do not need to be added, assembly complexity is lowered, and the fault occurrence probability is lowered. Moreover, the adaptation compatibility of the electric car is improved, and meanwhile the manufacturing cost of the electric car is reduced.

Description

technical field [0001] The invention relates to the field of automobile control, in particular to a complete vehicle controller of an electric automobile. Background technique [0002] Electric vehicles are complex systems composed of multiple systems. The vehicle controller (referred to as VCU) is the core management center of electric vehicle control. Its functions mainly include analyzing the driver's intentions, guiding the motor controller (referred to as MCU) Perform torque control, and at the same time manage and control the capacity and output of the power battery unit, DC / DC, on-board charger control, fault diagnosis of vehicle electrical components, and system-level fault handling, etc. Compared with traditional vehicles, current electric vehicles have insufficient technology maturity and market application, and the safety of on-board energy storage units requires integration of fault information collected by ECU for remote information monitoring and storage. Vehic...
