Latest Patents

Among his latest inventions is an object detection device designed for vehicles. This apparatus detects objects by utilizing a reflected wave from a probe wave. It calculates the relative velocity of the object in relation to the vehicle and estimates the azimuth of the object. The device also corrects the estimated azimuth by generating a velocity-azimuth curve, which indicates the relationship between the object's relative velocity and its azimuth. Additionally, it supplies a weight to an azimuth error and calculates a correction value based on a weighted average of the azimuth error.

Another notable invention is a getting-off support device for vehicles. This device issues an alarm for a predetermined time when it detects a physical body condition that obstructs an occupant's exit from the vehicle. The alarm continues to sound if both the physical body condition and the occupant's intention to get off are satisfied, prolonging the alarm time if these conditions persist.
