Control Systems for High Performance Electric Cars

Abstract

Electric vehicle technology opens doors to a wide range of research and improvement possibilities which can be used to develop a High Performance Full Electric Competition Car. However, in our modern-day society, there are numerous prejudices against electric vehicles which lead to their slow introduction in the market.In this context, IDIADA has been commissioned to build Volar-e with the aim to help overcoming the current technological and social barriers of electric vehicles and to set new standards in their behaviour. In order to achieve this target, Volar-e incorporates four independently controlled electric motors. What is more, a central concept to the vehicle is the integration of an intelligent torque distribution strategy to enhance road holding, handling and performance. Applus IDIADA's knowledge of torque vectoring technologies has led to further developments and, thus, to the incorporation of four active systems in the prototype: iTORQ+, iTORQ-, Traction Control and Launch Control. These systems have been designed with the objective of both maximizing lateral acceleration while maintaining vehicle stability and drivability and, in the overall, minimizing lap time around IDIADA's tracks. This paper highlights the improvement of Volar-e's behaviour thanks to implementing in it the previous mentioned control systems. A detailed model of Volar-e has been parameterized in CarSim©, encompassing not only a thorough powertrain model obtained from testing Volar-e's electric motors on a test-bench, but also a complete suspension model defined from K&C tests. By means of different simulation manoeuvres, the systems have been finely developed and adapted to fulfil the premise of achieving a high performance electric vehicle and to define the best initial set of parameters before passing from theory to practice. Last but not least, some conclusions are presented.

A Multidisciplinary Capstone Design Project to Satisfy ABET Student Outcomes

“…e team researched published articles on simulation and/or implementation of a SCADA system for an electric vehicle to design their own system [32][33][34][35][36].…”

Design, build, and test drive a FSAE electric vehicle

“…The CAN bus is connected to the Teensy through MCP2562 transceiver module [20]. The SCADA hardware includes the following sub‐systems: A brake over‐travel switch; TS master switch (TSMS); Grounded low‐voltage master switch; Two side‐mounted big red buttons (BRBs); Insulation monitoring device (IMD) interlock; Cockpit‐mounted shutdown button; Accumulator management system interlock; Two AIRs as the primary means of engaging and disengaging the TS voltage. A search of the published literature revealed only a partial simulation and/or implementation of a SCADA system for an EV [18, 21–25]. A complete software and hardware system implementation is absent from the current research.…”

Computer Simulation of Electric Vehicle Acceleration Processes With Different Positions of the Mass Center

“…It is necessary to note the works that determine the seriousness of the issue of working out the mechanical units of the vehicle [15,16], in order to improve safety and controllability. A number of works devoted to the analysis of vector control systems [17,18], considering an electric vehicle in dynamic driving modes. The work [19] is devoted to taking into account the road situation in ACS, for example, wind loads, slope and rolling friction.…”
