5 Specification of Plug-in Hybrid Bus 5/15 Hino Motors started pre-production of the Plug-in Hybrid bus in 2016 External view Length Width Height Passengers GVW Engine Motor Battery Charging Max Speed 8.9m 2.3m 3.0 m 32+1(Driver) 10,765kg Max 169kW Max 175kW 40kWh(Li-ion) Normal : AC200V Rapid : CHAdeMO 70 km/h

6 Specification of Plug-in Hybrid Bus Power train system 6/15 Drive mode(hybrid) Charge Clutch Connect Drive mode(ev) Discharge Charge Clutch Disconnect Engine stopped Discharge

7 System of Plug-in Hybrid Bus 7/15 Additional new devices for PHV-Bus Conventional system CCU PHV-ECU VCU TCU ECU Li-ion Battery inverter Motor Transfer Gear AMT Clutch plate Engine To be realization above system is important to build up HILS. First step : easy to build up HILS utilize already product devices.

8 How to build up effective the HILS 8/15 1st step: debug of software process The 1st HILS have to debug huge algorithm of software. 2nd step: calibration of parameters process The 2nd HILS is necessary to calibrate vehicle parameters. Target system increases power efficiency and fuel efficiency. Quicker performance of test maneuvers in all possible conditions and repetition. 2nd HILS has been improved according to 1st HILS and the added TruckMaker.
