Abstract:
The present invention relates to an image acquisition and processing method for vehicular exterior lighting control. Bi one aspect of the invention, there is provided acquiring images/synthesizing high-dynamic range (HDR) image (501), extracting features of light sources from image (502), identifying parent light sources and determined historical behavior (503), classifying light sources (504) and selecting and setting desired forward lighting state (505).
Abstract:
The present invention provides improvements in vehicle vision system components, vehicle vision systems and vehicle equipment control systems employing the vision system components and vision systems.
Abstract:
According to one embodiment of the present invention, a power supply circuit is provided for selectively supplying power to a vehicle accessory. The power supply circuit may be comprised of a switch coupled to a power line from the vehicle battery and to a power input of the accessory and a control circuit coupled to the switch The control circuit may monitor the battery voltage and selectively supply power from the battery to the accessory in response to the battery voltage. The control circuit may supply power from the battery to the accessory when the battery voltage changes at least a predetermined amount over a time period. The control circuit may comprise a microprocessor that adaptively learns signatures in the battery voltage occurring when the engine is running in order to provide power from the battery to the accessory as if the power were supplied from the ignition.
Abstract:
A vehicular vision system is disclosed (Fig. 1) comprising a high dynamic range (101, 102). The systems and methods are advantages for rear vision, collision avoidance, obstacle detection, adaptive cruise control, rain sensing (100), exterior light control (110), and lane departure warning, as well as other applications where a given scene may comprise objects having widely varying brightness values (120).
Abstract:
The present invention relates to a vehicle light control system (250) configured to distinguish between reflections off of a highly reflective surface and reflections off of atmospheric conditions of interest.
Abstract:
A vehicle communication and control system (100) is provided that may be more readily installed in a vehicle and that utilizes minimal additional wiring. According to some of the disclosed embodiments, the electrical components of the "brick" of a communication and control system are integrated into a rearview mirror assembly. Preferably, the microwave antenna (50) for the GPS (80) and the cellular telephone antenna (114) are also integrated into the rearview mirror assembly. Various functions and features of the system are also disclosed.
