Latest Patents

One of Sugai's latest patents involves a hybrid vehicle that includes an electronic control unit designed to correct the base driving force using a correction driving force. This hybrid vehicle comprises an engine, a first motor, a planetary gear mechanism, a second motor, a battery, and the electronic control unit. The electronic control unit is configured to set a shift stage based on the depression amount of the accelerator and the vehicle speed. It also establishes a base driving force based on the degree of accelerator depression, vehicle speed, and target rotation speed. Furthermore, it sets a correction driving force that increases with elapsed time after upshifting or an increase in vehicle speed after upshifting. The system controls the engine, first motor, and second motor to output a driving force that is corrected using the correction driving force to the drive shaft.

Another notable patent by Sugai describes a hybrid vehicle that includes an engine, a first rotating electric machine, and a second rotating electric machine coupled to the drive wheels. This vehicle also features a planetary gear mechanism that mechanically couples the engine and electric machines, along with an electric power storage device for charging and discharging. The electronic control unit in this design executes motoring control and simulated stepped gear shift control when cruise control is requested or when deceleration torque is needed.
