Latest Patents
Shinkawa's latest patents include a Motor Control Apparatus and an Electric Power Steering Apparatus. The electric power steering apparatus utilizes an inverter to drive-control a motor. It features a motor release-switch connected between the inverter and the motor. The control section detects the assist state in the driving control system and switches the inverter control ON/OFF based on the detection results. Additionally, a motor rotational number detecting section monitors the motor's rotational speed. An energy calculating section computes the energy of the motor's back-EMF and regenerative current based on this rotational number. A judging section compares this energy with a safety operation area for the motor release-switch, ensuring safety by switching it OFF when necessary. The safety operation area can also be adjusted based on temperature conditions.
Another patent focuses on a controlling apparatus for electric power steering. This invention includes a printed circuit substrate designed to minimize constraints on component layout while suppressing noise. The substrate features conductive patterns arranged in alternating odd and even numbered layers, separated by insulating layers. This innovative design allows for efficient component arrangement and noise reduction.
