Abstract: Described are techniques for generating, updating, and using sensor-based navigational maps. An input map is generated based on sensor data captured by a first sensor of a first vehicle. The input map is filtered based on one or more criteria to generate a filtered map corresponding to a three-dimensional representation of a route traveled by the first vehicle. The filtering can be based on detecting features using sensor data captured by a second sensor of the first vehicle. The one or more criteria can include object classes, distance criteria, and/or other criteria relating to attributes of features in the sensor data captured by the first sensor and/or the sensor data captured by the second sensor. The filtered map can be stored for transmission to a second vehicle, for use in determining a location of the second vehicle while the second vehicle is traveling along the same route.

Abstract: A coupling system for a torque transmission device of a motor vehicle includes a sliding sleeve. An actuator including a mobile member movable between a rest position and an activated position is linked to the sliding sleeve by a rotating kinematic link and by an elastic return member fixed in rotation about the axis of revolution.
