To interface the VCU, BMS and inverter so the driver can confidently control torque output from the motor, and to implement the systems that reduce energy losses over an endurance.
Calibration is labour rather than hardware, so it carries no costed parts. Its work product is the configuration that ties the vehicle control unit, battery management system and motor controller together: the accelerator pedal position to torque request map, the CAN protocols between the three devices, the current limits, and the driving strategies used to manage energy.
Torque-based against speed-based control is the open architectural question. A dynamic current limiter that reduces energy expenditure based on state of charge is the identified lever for endurance efficiency. Traction control was explicitly deferred rather than attempted in the first year. NOT COMPLETE. The system did not exist at the time of the CR26E scope review; the recorded state is "It not exist yet". Areas identified for investigation are the dynamic current limiter, CAN protocols across all three devices, torque-based against speed-based control, and the Speedgoat platform used by the EcoCAR team.
- Allow the driver to achieve a smooth torque response from the motor. - Implement systems that aid the car in reducing energy losses.
Nothing in CrimsonStorage covers these yet.
