Control algorithm development for parallel hybrid transit bus

The main concerns in concept design and prototype development for hybrid transit bus is to develop hybrid control algorithm for the power train. Targeting fuel economy the hybrid control strategy presented for transit bus can limit engine operation points within higher efficient area, meanwhile battery SOC can be maintained within reasonable level. With MATLAB/SIMULINK as a desktop the off-line simulation model for transit bus is developed and the hardware-in-the-loop simulation is conduced through dSPACE/Control Desk. Modular test facility is developed in order to debug and validate the hybrid control algorithm. The debug and validation of hybrid control algorithm is performed on developed modular test facility.
