He has made significant contributions to the field of automotive technology, particularly in damping force control devices and suspension systems. With a total of 6 patents, Okimura's work has had a substantial impact on vehicle performance and safety.

Latest Patents

One of Okimura's latest patents is a damping force control device. This device comprises variable damping shock absorbers, a detector, and a controller. Each shock absorber sets the damping coefficient from a minimum value to a maximum value to adjust the damping force. The detector monitors the vertical vibration state quantity related to the vibration of the sprung mass. The controller performs standard control to set the damping coefficient based on the vertical vibration state quantity, following a predetermined control law that assumes all wheels are in contact with the ground. When at least one wheel is ungrounded, the controller executes specific control to set the damping coefficient of the shock absorber corresponding to the grounded wheel to a first specific value greater than the minimum value.

Another significant patent is a suspension system that features a valve control device. This device executes specific valve control when a valve switching condition at high pressure is met. The specific valve control switches the spring constant change valves for the front wheel to a blocking state while allowing the rear wheel's spring constant change valves to communicate. The valve switching condition is satisfied when the oil pressure of hydraulic oil in the rear wheel side oil hydraulic cylinders exceeds a predetermined threshold, and the vehicle is determined to be in a specific traveling state.
