Throttle override safety system for ‘design induced pilot error’ in electric vehicles

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.
