Knowledge of experts is necessary for judging motor current waveforms. Here, we develop an automatic judgement system for motor current waveform by establishing an AI model trained by knowledge of experts and CAE technology.

The GS 450h that went on sale in 2006 uses a more powerful motor equipped with a new transmission called Two-stage motor speed reduction device to achieve superlative power performance. However, the increase in motor power meant that new technologies had to be developed to stabilize the system. This paper describes a high-speed power balance control technology that maintains a stable power balance even when the motor speed fluctuates sharply due to tire slippage or other factors, as well as a control technology that maintains a stable power balance even as the motor speed changes continuously during shifting.
