APPARATUS AND METHOD FOR CONTROLLING ELECTRIC VEHICLE INCLUDING TWIN CLUTCHES - A simplified explanation of the abstract
This abstract first appeared for US patent application 17947936 titled 'APPARATUS AND METHOD FOR CONTROLLING ELECTRIC VEHICLE INCLUDING TWIN CLUTCHES
Simplified Explanation
The patent application describes a method for controlling an electric vehicle with twin clutches. The method involves determining if the twin clutches can be disengaged, and if so, controlling them to have zero torque. Additionally, if the torque applied to the twin clutches is below a certain threshold, the drive motor is controlled to have zero RPM. Furthermore, if the speed of the drive motor falls below a predetermined speed, the drive motor is controlled to have zero torque.
- The patent application describes a method for controlling twin clutches in an electric vehicle.
- The method includes determining if the twin clutches can be disengaged.
- If the releasing condition is satisfied, the twin clutches are controlled to have zero torque.
- If the torque applied to the twin clutches is below a predetermined threshold, the drive motor is controlled to have zero RPM.
- If the speed of the drive motor is below a predetermined speed, the drive motor is controlled to have zero torque.
Potential Applications
This technology can be applied in various electric vehicles, including cars, trucks, and motorcycles.
Problems Solved
1. Efficient control of twin clutches in an electric vehicle. 2. Ensuring proper disengagement of the twin clutches. 3. Preventing damage to the drive motor by controlling it based on torque and speed conditions.
Benefits
1. Improved control and efficiency of the electric vehicle's twin clutches. 2. Reduced wear and tear on the twin clutches and drive motor. 3. Enhanced safety and reliability of the electric vehicle's drivetrain.
Original Abstract Submitted
A method of controlling an electric vehicle including twin clutches includes twin clutches for the electric vehicle driven by power of a drive motor and includes determining, by a clutch controller, whether a releasing condition for releasing engagement of the twin clutches is satisfied, controlling, by the clutch controller, the twin clutches to 0 torque when the releasing condition is satisfied, controlling the drive motor to 0 rpm by a vehicle controller when a torque applied to the twin clutches is less than a predetermined torque, and controlling the drive motor to 0 torque when a speed of the drive motor is less than a predetermined speed.
