With a total of 4 patents to his name, Matsuki continues to push the boundaries of innovation in the automotive industry.

Latest Patents

One of Matsuki's latest patents is a charging control apparatus designed for vehicles connected to external charging devices. This apparatus includes a voltage sensor that detects the voltage applied to the charging connector. It features a control device that estimates voltage variations during a predetermined period after the connector is connected. If the detected voltage variation exceeds a predetermined value, the system determines that a failure has occurred in the external charging device.

Another notable patent is the relay welding detector and detecting method. This invention increases the frequency of judgment for welding of relays, enhancing the likelihood of early detection. It determines that a battery is not being recharged or discharged when the vehicle speed is approximately zero and the brake pedal is pressed. The system controls a switching element of an inverter to discharge electric charges stored in a capacitor. After discharging, the relays are turned off, and voltages between the terminals of the relays are detected to judge whether the relays are welded.
