A design solution to reduce electrical/electronic complexity with secured CAN architecture for an automotive power system

Abstract

The word automotive at present scenario drives everybody’s attention to exponentially emerging technology that is electric vehicles (EV). EV’s are the combinations of drive train and various electrical and electronic systems. These large E/E systems in EVs are controlled by various control units, sensors and actuators Making the In-vehicle architecture complex. This paper mainly deals with this problem and provides a design approach to reduce the in-vehicle architecture complexity by making use of the CAN and if necessary, CAN-FD. This paper is divided into three sections, the section I shows the proposed gateway architecture using CAN. Section II is the electrical node simulation part for completing the offline architecture. Section III deals with the security of the proposed design solution. This paper work will be clearly be helpful for in-vehicle architecture design and control for the next generation vehicles. The simulation part makes use of MATLAB software and the feasibility of the solution is tested using the VECTOR CANOE software. This paper also covers some aspects of the battery modelling for offline analysis of the Li-Ion batteries in order to improve the efficiency of the battery and the battery management system used therein.
