Engine Map
- The base engine map is provided showing variation of engine torque (Nm) with engine speed (RPM)
- The dotted blue line indicates the OOL (Optimum operating line) with least bsfc (g/kwh)
- The red line indicates the max torque line for the engine
Built MATLAB scripts to simulate and plot several vehicle parameters based on three driving cycles viz:
- City driving cycle
- Highway driving cycle
- US06 driving cycle
Note:
- Regenerative braking is taken into consideration, observe SOC peaks during deceleration
- Control strategy is implemented for sustaining SOC between 100 % and 85 %
- Engine is turned on and off accordingly whenever battery SOC reaches the predefined limit (Control strategy implemented in MATLAB script)
