Title: Takefumi Hosaka: Innovator in Vehicle Control Systems
Introduction
Takefumi Hosaka is a prominent inventor based in Saitama, Japan. He has made significant contributions to the field of vehicle control systems, holding a total of 6 patents. His innovative work focuses on enhancing vehicle automation and improving driver experience.
Latest Patents
One of Hosaka's latest patents is a vehicle control system that embodies an autocruise control feature. This system introduces Fuzzy Logic, allowing the incorporation of an expert driver's operations or judgments made on a non-automated vehicle as fuzzy production rules. The control is executed based on rules that can be expressed linguistically in a simple manner, possessing predictive capabilities. The system detects the vehicle's operating conditions through parameters such as vehicle speed, vehicle acceleration, and changes in vehicle acceleration, which are then assigned on a scale known as the universe of discourse. The satisfaction degree is evaluated to select one rule, and a control value is determined from the selected rule, which is then output to an actuator for control.
Another notable patent is a method of indicating a shift operation of a manual gearbox in a vehicle. This method involves comparing a detected vehicle speed with a reference vehicle speed, which is determined and adjusted based on detected engine operational parameters. The system indicates when a shift operation should be performed based on the comparison results. The reference vehicle speed is corrected to a lower speed in response to an increase in the total running time of the vehicle, ensuring optimal driveability when the vehicle's running time is short.
