VEHICLE CONTROL DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240092342 titled 'VEHICLE CONTROL DEVICE
Simplified Explanation
The vehicle control device described in the patent application includes two traveling modes: one driven by the torque output from a rotary electric machine and the other driven by the engine torque output in combination with the electric machine's torque output. During the transition from the first traveling mode to the second, there are sections for cranking the engine using the output of a second rotary electric machine and assisting the driving force of the engine using the output of the first rotary electric machine. Additionally, the torque increase of the first electric machine is limited in a specific section.
- Vehicle control device with two traveling modes: one driven by electric machine torque and the other by engine torque combined with electric machine torque.
- Sections for cranking the engine and assisting engine driving force during mode transition.
- Limitation of torque increase in the first electric machine during a specific section.
