Simulation Ensures Green Buses can hit the Road on Time

Share |

Electronics News Report a six-strong engineering team at Dongfeng Electric Vehicle (DFEV) faced a tough challenge: design, test and verify the battery management control system for the EQ6110 hybrid electric city bus – lowering emissions and improving fuel efficiency by 30 percent – and then generate production C code for the controller, in record time.

The control strategies for battery management and vehicle energy management are vital for meeting the performance and fuel economy specifications of HEVs.

 To make things even harder, the controllers have to be optimised to suit the dynamics of individual vehicles.The Engine Control Unit (ECU) for the EQ6110 is based on a Freescale S12 microcontroller (MCU).This 16-bit Controller Area Network (CAN) device is designed specifically to look after automotive and industrial applications.
