Latest Patents

One of his latest patents is the "Drive control apparatus and method for vehicles." This invention involves a drive control apparatus for a vehicle equipped with an internal combustion engine and an electric motor. The system includes a drag motion detection section that identifies when the electric motor experiences drag motion due to idle torque from the clutch. Additionally, it features a reverse torque control section that manages the electric motor's torque in the opposite direction of the detected drag motion.

Another notable patent is the "Vehicle drive force control apparatus." This apparatus is designed to prevent the co-rotation of the motor caused by the rotation of wheels when the clutch connecting the wheels and the motor is disengaged. The motor is braked by short-circuiting the armature, and further braking is applied by setting the field current to zero once the motor's rotational speed reaches zero. This innovative approach ensures that the braking force decreases in accordance with the motor's decreasing rotational speed.
