DUAL-MODE VEHICLE REAR VISION SYSTEM

摘要

A dual-mode rear vision system for an automotive vehicle includes an electro-optical imaging device operable in a short range mode to image a backup region immediately rearward of the vehicle and operable in a long range mode to image a collision threat region rearward of the backup region. The imaging device assumes the short range mode when the vehicle is in a reverse travel mode and assumes the long range mode when the vehicle is in a non-reverse travel mode. An electronic control module (ECM) analyzes imagery from the imaging device to detect backup hazards when in the reverse travel mode, and to detect rear collision threats when in the non-reverse travel mode. The ECM activates an occupant protection system if a collision threat is detected, and generates a driver alert and/or a braking intervention if a backup hazard is detected.
