Abstract
A vehicle equipped with a driving assistance system with a low power mode, the vehicle includes an image capturing device and a processor. The image capturing device capture external scenes outside of the vehicle to generate a series of observing images. In a low power mode, the processor identifies a second vehicle and a plurality of features on exterior of the second vehicle, determines a reference vector corresponding to a travel direction of the second vehicle according to at least two features, and determines if a change of a detection value relating to the reference vector in the series of observing images exceeds a predetermined threshold. When the reference vector exceeds the predetermined threshold, the processor determines that the second vehicle has changed the travel direction.
