Latest Patents
Among his latest innovations is the "Steering Control Apparatus and Steering Control Method." This invention involves a control computing unit that allocates the current axial force and the transverse-G axial force at a predetermined allocation ratio. It calculates a feedback axial force, which is the steering-rack axial force, and drives the reaction force motor based on this calculated feedback. Notably, the allocation ratio of the transverse-G axial force is set to be greater than that of the current axial force. Another significant patent is the "Steering Control Device," where a control computing unit blends a feedforward axial force and a feedback axial force at an allocation ratio. This is based on various parameters such as axial force difference, lateral acceleration, vehicle velocity, steering angle, and steering angular velocity to set a final axial force.
