Equipment servicemanual for operating

Assembling and disassembling teaching software

The software is installed into the tablet fixed on the running platform.

Assembling and disassembling Prius engine

Create 3D Prius engine model in the VR environment. The students can zoom out, zoom in or rotate the parts and observe the internal mechanism.

Perspective: Perspective parts, such as, engine assembly, case, inner parts.

Virtual assembling and disassembling instructional software. Assemble and disassemble the engine parts with manual and automatic as the order of the service manual.

Cognitive parts: Supply explodeddiagram and every part.

Assembling and disassembling Prius transmission

Create 3D Prius transmission model in the VR environment. The students can zoom out, zoom in or rotate the parts and observe the internal mechanism.

Perspective: Perspective parts, such as, engine assembly, case, inner parts.

Virtual assembling and disassembling instructional software. Assemble and disassemble the transmission parts with manual and automatic as the order of the service manual.

Cognitive parts: Supply explodeddiagram and every part.

Teaching software of hybrid system about converting energy

The software is installed into the 7 inch PAD for showing and studying the line about converting and translating hybrid system.

Working cycles: Compared Atkinson cycle with Otto cycle in the VR environment

Convert energy at typical conditions: Show the current flow direction with arrowhead, yellow one means discharge the battery, and green one means charge the battery. You can observe the piston and crankshaft how to run for judging the engine power is outputting or not.

Starting out model: The battery supplies power, and control MG2 by converter to start out the car.

Low speed travel model: The battery supplies power, and control MG2 by converter to drive the car.

Low speed cruising model: The engine supplies power to drive planet, then drive MG1, charging the battery as an alternator, and drive the MG2 with parts of power by the converter.

Full acceleration model: The engine supplies power to drive planet, at the same time, the battery supplies power to drive MG1 and MG2.

Braking model: The engine stops and MG2 is driven by the wheels to charge the battery as an alternator, and brake the car.

Stop model: All powers stop.

Reverse model: The battery supplies power to drive MG2 for reversing the car.

Synchronous operation function:

When the engine or hybrid system rotate, driven by reducing motor, the pad should display energy convert synchronous operation.

A tablet personal computer(PC) is installed in the panel of the bench, on which the teaching software of hybrid system about converting energy.
