TURNING CONTROL DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18236980 titled 'TURNING CONTROL DEVICE

Simplified Explanation

The abstract describes a turning control device with four processors that work together to calculate and adjust torque and compensation values for a turning mechanism in a vehicle based on target and actual pinion angles and angular velocities.

• The first processor calculates a torque command value based on the difference between the target pinion angle and the actual pinion angle.
• The second processor calculates a compensation value to adjust for resistance in the turning mechanism based on the difference between the target pinion angular velocity and the actual pinion angular velocity.
• The third processor limits the variation range of the torque command value and the compensation value based on preset limit values.
• The fourth processor calculates the final turning torque command value by subtracting the compensation value from the torque command value.
• The third processor adjusts the limit values based on the vehicle's traveling state.

Potential Applications: - Automotive industry for advanced steering control systems - Robotics for precise turning mechanisms

Problems Solved: - Improves accuracy and efficiency of turning mechanisms - Enhances overall vehicle control and stability

Benefits: - Increased precision in turning control - Enhanced vehicle performance and safety - Improved user experience and comfort

Original Abstract Submitted

A turning control device includes a first processor, a second processor, a third processor, and a fourth processor. The first processor calculates a torque command value based on a difference between a target pinion angle and a pinion angle. The second processor calculates a compensation value compensating resistance of a turning mechanism based on a difference between a target pinion angular velocity and a pinion angular velocity. The third processor limits a variation range of the torque command value based on a limit value of the torque command value and limits a variation range of the compensation value based on a limit value of the compensation value. The fourth processor calculates a turning torque command value by subtracting the compensation value from the torque command value. The third processor changes the limit values based on a traveling state of a vehicle.
