Design of driving interface device for electric vehicle

Abstract

Currently, most vehicles are controlled by human interactions with steering wheel, brake and accelerator pedals. Thus it is required to establish an acquisition system to gather and process these signals from the driver; and then send them to the vehicle’s controllers. In this paper, we propose a design of the driving interface device for the electric car named i-MiEV by Mitsubishi Motors. This device is constructed based on the digital signal microcontroller dsPIC30F4011 from Microchip, and communicates with the vehicle control system through Controller-Area-Network (CAN) and Serial-Peripheral-Interface (SPI) protocols.
