Abstract: A method detects false positives of an image-processing device of a camera located on-board a vehicle and that delivers data for modelling a marking line. The method includes: determining a first distance from the vehicle to the marking line at a first instant in time, determining a second distance from the vehicle to the marking line at a second instant, computing an initial discontinuity, in which an initial discontinuity equal to the absolute value of the difference between the first distance and the second distance is computed, and detecting a false initial-discontinuity positive, in which the initial discontinuity is compared to a predefined initial low threshold.

Abstract: A method for automated management of the longitudinal speed of a first vehicle travelling on a first lane includes: detecting an intention of a second vehicle travelling on a second lane adjacent to the first lane to perform an insertion maneuver on the first lane; estimating a corrected longitudinal distance, the corrected longitudinal distance corresponding to the longitudinal distance that will separate the first vehicle from the second vehicle at the end of the insertion maneuver, the corrected longitudinal distance being calculated as a function of a measured longitudinal distance between the first vehicle and the second vehicle, and as a function of a relative longitudinal speed measured between the second vehicle and the first vehicle; and calculating a longitudinal speed setpoint of the first vehicle as a function of the corrected longitudinal distance.

Abstract: The initial capacity and cycle durability are improved in a secondary battery which uses a sulfide solid electrolyte containing sulfur and phosphorus and high nickel-type positive electrode active material. In the secondary battery having a power generating element containing, laminated in this order, a positive electrode with a positive electrode active material layer containing a positive electrode active material composed of a so-called high nickel-type lithium-containing composite oxide, an electrolyte layer which contains a sulfide solid electrolyte containing sulfur and phosphorus, and a negative electrode with a negative electrode active material layer containing a negative electrode active material, one or more added element selected from the group consisting of B, P, S and Si is made to be present in a molar concentration larger than that of Ni, into a surface layer region having a depth within 100 nm from the surface of a particle of the lithium-containing composite oxide.

Abstract: A vehicle management system, an on-vehicle system, and a vehicle management method are described that are capable of providing a vehicle to a user where an odor level in the vehicle fulfills a predetermined criterion. The vehicle management system selects a provision option of the vehicle, corresponding to the odor level if the odor level does not fulfill the predetermined criterion, and executes notification or vehicle control associated with the provision option.

Abstract: An occlusion is identified in a vehicle transportation network. A visibility grid is identified on a second side of the occlusion for a vehicle that is on a first side of the occlusion. The visibility grid is identified with respect to a region of interest that is at least a predefined distance above ground. The visibility grid is used to identify first portions of roads sensed by a sensor positioned on the vehicle and second portions of the roads that are not sensed by the sensor. A driving behavior of the vehicle is altered based on the visibility grid.
