Introduction
Nobutaka Oowa is a notable inventor based in Toyota, Japan, recognized for his contributions to vehicle height adjustment technologies. With a total of 6 patents, Oowa has developed innovative systems that enhance vehicle performance and safety.
Latest Patents
Oowa's latest patents include a "System for Vehicle Height Adjustment with Steering Angle Change Rate." This system features multiple actuator assemblies, each corresponding to a vehicle wheel, which resiliently suspends the wheel from the vehicle body. The actuator assemblies contain pressure chambers that adjust the vehicle height based on the supply or discharge of working fluid. The system also incorporates vehicle height detection means and a mechanism to compute and control the working fluid supply, ensuring that actual wheel heights align with standard heights while compensating for fluctuations caused by steering angle changes.
Another significant patent is the "System for Vehicle Height Adjustment with Loading Deviation Correction." Similar to his previous invention, this system utilizes actuator assemblies to manage vehicle height. It includes wheel loading detection means to sense the load imposed by the vehicle body on the wheels. The control mechanism adjusts the working fluid supply based on deviations from standard wheel loadings, particularly when the vehicle speed is below a certain threshold.
