Latest Patents

One of his latest patents is titled "Method and system for diagnosing a drivetrain during shifting operations." This invention provides a sensing system and method for delivering information related to a drivetrain during shifting operations. The drivetrain consists of an engine, a torque converter, and a transmission. The system incorporates sensors that detect the output speeds of the engine, torque converter, and transmission. It identifies the starting condition of a shifting operation, determines a set of performance parameters, and generates corresponding performance parameter signals.

Another significant patent is the "Integrated engine and transmission control system." This control system regulates engine speed during shifts to minimize driveline torque and shift shock. It features separate microprocessor-based controllers for the engine and transmission that communicate through a data link. Upon initiating a shift, the transmission controller delays a specified period to disengage the old gear ratio before producing a speed signal. The system adjusts engine speed in accordance with the desired speed during both upshifts and downshifts, enhancing the overall performance of the vehicle.
