Title: Yusuke Otogawa - Innovator in Steering Control Technology
Introduction
Yusuke Otogawa is an inventive mind based in Kariya-city, Japan. He is known for his contributions to steering control technology, focusing on enhancing vehicle safety and performance. Although he currently holds no granted patents, his innovative ideas are reflected in his latest patent applications.
Latest Patent Applications
One of his notable applications is for a STEERING CONTROL DEVICE, which features an assist control unit that calculates an assist torque command based on the steering torque. This device includes a steering angle control unit that determines a steering angle control torque command, ensuring that the steering angle follows a target steering angle from a lane-keeping support device. Additionally, a vibration application control unit is designed to apply vibration to the assist torque when a lane departure warning is activated. The motor drive control unit manages the motor's drive based on the combined values of the assist torque command, steering angle control torque command, and lane departure warning control torque command. Furthermore, the steering angle control unit incorporates a vibration removal filter to eliminate unwanted vibration frequency components during steering angle control calculations.
Another application for a STEERING CONTROL DEVICE involves a servo controller that calculates a base assist command to ensure the steering torque aligns with a target steering torque. An estimated load torque calculation section determines the estimated load torque based on the target steering torque and base assist command. The target steering torque calculation section utilizes a map that defines the relationship between the estimated load torque and the target steering torque. The servo controller is equipped with a low-pass filter to remove high-frequency components from the input target steering torque, allowing for precise differential control calculations.
Conclusion
Yusuke Otogawa's innovative approaches to steering control technology demonstrate his commitment to improving vehicle safety and performance. His latest patent applications reflect a deep understanding of the complexities involved in steering systems. As he continues to develop his ideas, he may contribute significantly to advancements in automotive technology.
