HYBRID ALL-WHEEL-DRIVE VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17928820 titled 'HYBRID ALL-WHEEL-DRIVE VEHICLE
Simplified Explanation: The patent application describes a system in a hybrid electric vehicle (HEV) that adjusts torque distribution when climbing over bumps to improve stability and performance.
- The system increases regenerative torque of the first motor generator and reduces output torque of the second motor generator when climbing over a bump with the front wheels.
- It also increases the engagement force of the LSD clutch in the center differential unit to reduce input torque of the front LSD.
- When climbing over a bump with the rear wheels, the system adjusts torque distribution similarly but for the rear LSD.
Key Features and Innovation:
- System in HEV adjusts torque distribution when climbing over bumps for improved stability.
- Increases regenerative torque of first motor generator and reduces output torque of second motor generator.
- Adjusts engagement force of LSD clutch in center differential unit to optimize torque distribution.
- Enhances performance and stability of the vehicle during challenging driving conditions.

Original Abstract Submitted
When the operation amount of an accelerator exceeds a predetermined value at a time of climbing over a bump with either one of right and left front wheels, a HEV-CU increases the regenerative torque of a first motor generator, reduces the output torque of a second motor generator, and increases the engagement force of a LSD clutch of a center differential unit so as to reduce the input torque of a front LSD. When the operation amount of the accelerator exceeds the predetermined value at a time of climbing over a bump with either one of left and right rear wheels, the HEV-CU increases the regenerative torque of the first motor generator, reduces the output torque of the second motor generator, and reduces the engagement force of the LSD clutch so as to reduce the input torque of the rear LSD.
