TL;DR: The paper discusses an innovative way in which safety systems of a highly safe Formula electric vehicle was achieved by Analog circuits designing and Electronic Control Unit (ECU) programming, taking into consideration different possibilities and at the same time conforming to the uncompromising rules of FSAE.
Abstract: Developing an Electric Formula car has its own challenges associated with it, perhaps what convol utes the case is the proper safety measures that needs to be in place to ensure the well being of the driver. A formula car must perform well as to achieve extremely high speed in a really small time frame, and also keep a tab on proper working of all the components which otherwise could be catastrophic. While Mechanical parts have their own safety standards and measures in place, electrical parts and safety designing should follow the stringent rules of FSAE. The paper discusses an innovative way in which safety systems of a highly safe Formula electric vehicle was achieved by Analog circuits designing and Electronic Control Unit (ECU) programming, taking into consideration different possibilities and at the same time conforming to the uncompromising rules of FSAE.

TL;DR: This paper sees how the Electric Vehicle runs by using this protocol in accordance with the FSAE standards and improves the safety and reliability of the vehicle by the application of the CAN transmission protocol.
Abstract: The aspects of energy conservation and environmental protection are the need of the hour. Hence, the battery electric vehicles came into existence and are operated for various purposes. The most important part of these vehicles is the safety systems. The operation of the safety systems installed in Pedal Assembly, Dash Board, Battery pack, Motor Controller can be made less complicated and faster by using Controller Area Network (CAN) protocol. Keeping design simplicity in mind CAN protocol is used to make the system less bulky by reducing the number of wiring. In this paper, we see how the Electric Vehicle runs by using this protocol in accordance with the FSAE standards. The main motive of the paper is to improve the safety and reliability of the vehicle which is achieved by the application of the CAN transmission protocol.

TL;DR: This paper has focused on developing a safety system for a formula electric car keeping design simplicity in mind and the systems and circuits proposed in this paper are in accordance with the FSAE rules.
Abstract: Energy conservation, environmental conservation and sustainable development are the need of the hour and in this regard the development of an electric vehicle has become topmost priority. There is a growing concern about the safety of EVs, which have transformed the future of the automobile industry. With this rapid growth there is a increasing requirement for monitoring and development of safety circuits for battery pack, drivetrain and during emergencies. In this paper we have focused on developing a safety system for a formula electric car keeping design simplicity in mind. All the systems and circuits proposed in this paper are in accordance with the FSAE rules. As part of this project an analysis methodology for analysis of safety systems has been developed and the potential impacts of these circuits have been studied.

TL;DR: In this paper , a robust safety circuit Brake system Plausibility Device (BSPD) is designed and tested for Formula student electric development, which includes various challenges from both mechanical and electrical fronts.
Abstract: Electric Vehicles are growing faster than the traditional combustion vehicles which are powered by conventional energy resources because of the environmental concern and to attain sustainable development. Formula student is one of the world’s largest student-run competitions. Formula student electric development includes various challenges from both mechanical and electrical fronts. Mechanical parts have their safety standards and measures whereas for electrical front robust safety circuitry must be prepared to reduce the risk of any fatal accident. Generally, Formula student cars are fast and good acceleration, to avoid wheel-to-wheel racing and drag racing or other dangerous stunts, a robust safety circuit Brake system Plausibility Device (BSPD) is designed and tested. This paper discusses the designing, robustness of BSPD devices.

TL;DR: The trivial components are shortened from the formula race car to enhance the safety and achieve a performance boost in the car.
Abstract: Formula Bharat is an Indian Formula Student competition whose objective is to check the consciousness of viable building knowledge and understudy innovation through a focused stage. The challenge enables the teams to use an engine having a maximum displacement of 710 cc. Considering all the parameters, KTM RC390 engine was selected for the challenge on account of its unwavering quality, execution, and different components like engine control unit (ECU) to provide the most favorable execution and to obtain optimized performance. Being a formula student team, one must draw its whole attention toward weight reduction, and some of the components in the main harness of the KTM engine adds to the excessive weight; therefore, the trivial components are shortened from the formula race car. In order to achieve maximum efficiency, thorough study of the sensors, their respective connections, and ports were done. A PCB of BSPD and researched work on shutdown circuit which contains some safety components and switches for different hazardous situations has also been included. Taking all the concepts into consideration planning, designing and execution of all the methodologies for performance optimization of the formula race car have been achieved. The main objective of this research was to enhance the safety and achieve a performance boost in the car.

TL;DR: This paper provides solution to a specific problem called ‘design induced pilot error’ by overriding the throttle pedal when incidents like ‘panic braking’, ‘hard braking” occur and provides better control to experienced drivers in maneuvering the vehicle.
Abstract: Electric or Battery driven vehicles are the present and future of road transport. Safety systems for these vehicles are important due to the powertrain dealing with high current and absence of clutch. This paper provides solution to a specific problem called ‘design induced pilot error’. Such errors occur due to placement of pedals in the vehicle or due to lack of experience and as a result, both the throttle and brake pedals are pressed simultaneously. These incidents may have serious repercussions, such as toppling of the vehicle or other such accidents. It is solved by overriding the throttle pedal when incidents like ‘panic braking’, ‘hard braking’ occur. The circuit, realized using analog circuitry detaches the drive train from the shaft, thus freewheeling the vehicle. This leads to only the brakes interacting with the wheels, thus reducing the risk of a calamity. This system, in addition to aiding inexperienced drivers, provides better control to experienced drivers in maneuvering the vehicle.
