Latest Patents

One of his latest patents is a method of updating a control unit for a vehicle. This method involves generating raw difference data by comparing an old version of data with a new version of data. It further includes generating divided difference data by dividing the raw difference data for each memory sector. The process culminates in updating the old version to the new version using the divided difference data.

Another notable patent is an apparatus and method for controlling the alternator of a vehicle. This method allows for the adjustment of a Pulse Width Modulation (PWM) duty cycle change rate to reach a target PWM duty cycle after the initial engine stabilization. The method increases the PWM duty cycle using an initial rate received from an ECU to prevent engine overload when the current PWM duty cycle is below a predetermined reference. It also allows for real-time adjustments to suppress engine RPM fluctuations and improve the response speed of the alternator output voltage.
