Title: Tsugio Tomita: Innovator in Electronically Controlled Throttle Systems
Introduction
Tsugio Tomita is a notable inventor based in Hitachi, Japan. He has made significant contributions to the field of electronically controlled throttle systems, holding a total of 6 patents. His work focuses on enhancing vehicle safety and performance through innovative throttle control mechanisms.
Latest Patents
One of Tomita's latest patents is an electronically controlled throttle control system. This invention ensures that even when the throttle valve operates independently of the engine control system, any abnormal engine behavior is detected. The system comprises an electronically controlled throttle system, an engine control system, and an engine speed monitoring unit. This arrangement allows for the monitoring of engine behaviors, ensuring that if the throttle valve operates independently and abnormal behavior is detected, the system can take necessary fail-safe actions, such as stopping the throttle valve operation.
Another significant patent is the throttle controlling device. This electronic control throttle body features a default mechanism that secures the self-propelling of a vehicle in case of a fault. The throttle control unit adjusts the throttle valve position using a motor based on a target opening degree from the engine control unit. If the target opening degree exceeds a default mechanism's threshold, the system resets the integration value to zero and performs feedback control to maintain optimal operation.
