Methods and systems for collecting driving information and classifying drivers and self-driving systems

Systems and methods for efficiently addressing technical and privacy / authorization obstacles associated with tracking of individuals in a vehicle, and enabling route-based analysis to determine driving behavior, socio-demographics, future profitability, and interests of individuals or self-driving systems. Driving information is collected using a device associated with a driver and a vehicle or using data collected by systems of self-driving vehicles. The frequency and methods used for the collection of driving information can be modified based on location and movement of the device and based on previous classification of the driver or self-driving system, thereby enabling efficient use of bandwidth and battery and increasing accuracy of the classification. The driving information is encoded and transmitted to a server, where future typical route segments that the driver is likely to travel are predicted, and the driver, or the self-driving system, is classified into one or more groups based on the encoded driving information.

Self-driving vehicle with integrated active suspension

A self-driving vehicle with an integrated fully-active suspension system. The fully-active suspension utilizes data from one or more sensors used for autonomous driving (e.g. vision, LIDAR, GPS) in order to anticipate road conditions in advance. The system builds a topographical map of the road surface. Suspension and road data is delivered back to the vehicle in order to change autonomous driving behavior including route planning. Energy storage is regulated based on a planned route. Forward and lateral acceleration feel is mitigated through active pitch and tilt compensation. The fully-active suspension pushes and pulls the suspension in three or more operational quadrants in order to deliver superior ride comfort, handling, and / safety of the vehicle.

Vehicle localization using surface penetrating radar

Described are a method and a system for localization of a vehicle. The method includes the acquisition of SPR images of a subsurface region along a vehicle track. Acquired SPR images are compared to SPR images previously acquired for a subsurface region that at least partially overlaps the subsurface region along the vehicle track. In some embodiments, the comparison includes an image correlation procedure. Location data for the vehicle are determined based in part on location data for the SPR images previously acquired for the second subsurface region. Location data can be used to guide the vehicle along a desired path. The relatively static nature of features in the subsurface region provides the method with advantages over other sensor-based navigation systems that may be adversely affected by weather conditions, dynamic features and time-varying illumination. The method can be used in a variety of applications, including self-driving automobiles and autonomous platforms.

Body diode conduction optimization in mosfet synchronous rectifier

To maximize power efficiency, dead time between “on” times of a synchronous rectifier (“SR”) MOSFET switch and a main switch for CCM operation in particular in isolated and non-isolated self-driven synchronous DC-DC converters needs to be optimized. To accomplish that objective, the latest conduction time t of a body diode of the SR MOSFET following conduction thereof is determined, compared with a selected fixed optimum period T1, and incrementally or decrementally adjusted in a subsequent switching cycle while t is unequal to T1, depending on whether t is shorter or longer than T1, so that t eventually is made substantially equal to T1 in length. This process is to be repeated continuously.
