Latest Patents

Tsuchiya’s listed inventions include “Lane Structure Estimation” and “Vehicle Stop Position Determination System and Vehicle Stop Position Determination Method.”

“Lane Structure Estimation” describes a vehicle-mounted processor that generates and aligns lane cues as the vehicle travels. Using those cues, it estimates a lane graph and compares the estimated lane center with a landmark to check its location. The system is designed to operate even when the vehicle is temporarily without GPS or GNSS communication.

The vehicle stop-position invention combines environmental and vehicle sensors with a processor. It determines a stop position for a road intersection by considering the vehicle’s driving status and its position relative to the intersection.
