Appl. No.:

12/110618

Inventors:

XiaoYong Wang - Sunnyvale CA, US
Jizhang Shan - Cupertino CA, US
Donghui Wu - Sunnyvale CA, US

Assignee:

OmniVision Technologies, Inc. - Santa Clara CA

International Classification:

H04N 9/64
H04N 5/20

US Classification:

348251, 348255

Abstract:

An image sensing system provides for accurate lens shading correction even when there is significant lens shading asymmetry and non-uniformity. A two-dimensional B-spline technique is used to determine lens shading correction surfaces. The number of zones is selected to achieve accurate correction of center, edge, and corner regions of an image. Separate lens shading correction surfaces are calculated for a set of standard illuminants to permit lens shading correction to be adapted based on the illuminant used to capture the image.

3482231, 348360

Abstract:

An image sensor system includes an image sensor that can be exposed with light from an illuminated scene to produce a secondary image, a meter sensor that can be exposed with light from the illuminated scene to produce a meter secondary image, and an image processor. The image processor can be configured to determine an average pixel color in the secondary image. The image processor can also be configured to determine a white balancing point in response to the secondary image average pixel color, the meter secondary image, meter calibration information for the meter sensor, and the image calibration information for the image sensor.

International Classification:

B60W 20/00

US Classification:

701103, 701 99, 180 6528, 903905

Abstract:

A method and system for limiting a fast transient in an engine in a hybrid vehicle is provided. The predicted fuel loss percentage is calculated from an inferred air-fuel ratio (inferred lambda). The rate limit term is calculated from a measured air-fuel ratio (measured lambda) and an engine torque command change rate. The predicted fuel loss percentage and the rate limit term are inputs into a calibration table to determine an engine power rate limit and an engine torque rate limit. An engine torque command is limited using the engine torque rate limit to control a fast engine torque transient for an engine. An engine power command is limited using the engine power rate limit to control the fast engine power transient for the engine.

Abstract:

A hybrid electric vehicle powertrain having a mechanical power source and an electro-mechanical power source, including a generator, a motor and a battery. Driving torque developed by the mechanical power source is delivered through one clutch of a geared transmission to a power output shaft. The electric motor of the electro-mechanical power source delivers driving torque through a second clutch of the geared transmission. A mechanical reverse drive torque is used to improve reverse drive performance. A reduction in duration of operation in a negative power split during a driving event is achieved to improve vehicle powertrain efficiency. A series drive is available as the mechanical power source drives the generator to charge the battery, which drives the motor. The generator may act as an engine starter motor.

US Classification:

701 22, 903903

Abstract:

A vehicle powertrain includes an engine, an electric machine operable to output torque to at least one vehicle wheel, and an electric power source operable to provide electric power to the electric machine. A method for optimizing powertrain efficiency includes generating a plurality of three-dimensional maps of optimized engine speeds for combinations of vehicle power and vehicle speed at a plurality of predetermined powers of the electrical power source. Each of the maps corresponds to one of the predetermined powers of the electrical power source. The maps are used to determine an optimized engine speed for a given power of the electrical power source, a given vehicle power and a given vehicle speed.

Abstract:

A method for determining a route for a vehicle includes receiving input indicative of a driver's dynamic control of the vehicle, determining the driver's driving style based on the input, and selecting values of parameters representing the driver's anticipated dynamic control of the vehicle based on the driving style. The method also includes identifying a plurality of candidate routes between an origin and destination, partitioning each of the candidate routes into a set of predefined route patterns, and determining an energy usage associated with each of the candidate routes based on the selected values and the set of predefined route patterns defining the candidate route. The method further includes identifying the candidate route having the minimum energy usage and providing output describing the route having the minimum energy usage.
