Abstract: To localize a vehicle in the given map precisely for autonomous driving, the vehicle needs to compare the sensor perceived environment with the map information accurately. To achieve this, the vehicle may use information received from multiple on-board sensors in combination of GPS and map data. Example implementations described herein are directed to maintaining accuracy of sensor measurements for autonomous vehicles even during sensor failure through a raw data fusion technique and a repopulation of data through a prediction technique based on historical information and statistical method if any of the sensors fail.

Abstract: In the present invention, it is possible to accurately predict, at an earlier timing, that a pedestrian will perform constant speed movement or a route change that is more complex than the constant speed movement. Provided is a travel control device that can accurately determine a change in the route of the pedestrian according to a change in the pedestrian's posture and, in particular, a change in the orientation of the body or a change in an inverted angle, and that can appropriately control the travel of the vehicle.

Abstract: Example implementations involve systems and methods to control the ego vehicle to trace connected plural curved paths, which are calculated as the movement of the vehicle against vertical repulsive force from straight or curved walls, and connected continuously at the joints, and differentiable by position at the joints. Further, the repulsion force acts as deceleration force and lateral force.

Abstract: A vehicle motion control system is capable of defining clear guidelines on more specific control timing associated with accelerating, steering, and braking operations, and conducting motion control based on the defined guidelines. An ideal motion control unit within a central controller uses longitudinal jerk information of a vehicle to control the steering of the vehicle. Information for determining the initiation timing of steering is presented from a human-vehicle interface (HVI) to a driver. In accordance with the information presented from the HVI, the driver controls the initiation timing of steering.
