Title: Seiko Tamada: Innovator in Engine Control Technologies
Introduction
Seiko Tamada is a notable inventor based in Toyota, Japan. He has made significant contributions to the field of engine control technologies, holding a total of 3 patents. His work focuses on enhancing the efficiency and functionality of internal combustion engines.
Latest Patents
One of his latest patents is a control device for a variable valve mechanism. This invention involves a brushless motor that varies an actuation parameter of an intake valve of an engine. A position sensor outputs a pulse signal when the brushless motor rotates, and a position counter calculates a counter value by counting edges of the pulse signal. The motor control device obtains a detection value of the motor rotational angle based on the counter value when it is in a powered state. The engine control device determines that the detection value is displaced from the actual value when it detects that the engine is operating and the motor control device is in a non-powered state.
Another significant patent is for an internal combustion engine control system. This system restores power supply from a backup source to a volatile memory after a temporary suspension. A remaining data determining section checks whether the data in the volatile memory is the same as that stored immediately before the power supply suspension. If not, a reference value learning section moves an actuator to a limit position, assigns the reference value to an initial value, and clears the change history. If power suspension occurs again before the reference value learning is complete, the control section invalidates the previous determination and continues the learning process once power is restored.
