All details should be treated as preliminary. This document is proprietary and confidential • Control Systems • Throttle • Driver throttle Demand via a shaping map (user defined) goes into a look up table (6 selectable preconfigured maps) which translate to a torque application. • Preconfigured maps will provide different power curves to suit different periods of the race. All details should be treated as preliminary. This document is proprietary and confidential • Control Systems • Brake Regen • Braking Demand via a shaping map (user defined) is translated to an “Engine Braking” demand to provide retardation and energy harvesting during the braking zones. • Preconfigured maps will provide different regen curves to suit different driver requirements and match the need for different amounts of energy saving throughout the race. All details should be treated as preliminary. This document is proprietary and confidential • Control Systems • Regen Paddle • An analogue paddle exists that will provide an input (similar to a hand throttle) to allow the driver to apply variable amounts of engine braking, irrespective of mechanical Brake Pressure. • This will allow drivers a more flexible approach to “Coast and Lift” when saving energy. • All torque demands are summed. All details should be treated as preliminary. This document is proprietary and confidential •Safety and Switches All details should be treated as preliminary. This document is proprietary and confidential •Communications All details should be treated as preliminary. This document is proprietary and confidential •Dyno running • Completed 4,200 kms (equivalent to ~3 seasons) • Completed 4,000 gearshifts All details should be treated as preliminary. This document is proprietary and confidential •Track running • Testing with Low Power battery has validated majority of on car systems. • Next step 200kW! All details should be treated as preliminary. This document is proprietary and confidential •Future Developments • System is modular which will allow any component to be upgraded or updated as new technologies become available without obsoleting the rest of the system. • Chassis Harness has specifically broken out a number of spare signals (CAN, Serial, USB, Ethernet, Analogues, Digitals) to provide for future expansion and to minimise costs of additional requirements (Power Indicators, additional sensors, driver biometrics, TPMS).
