Abstract: A side mirror system for a vehicle is provided, including right and left mirror units, each including multiple mirrors, which are configured to be adjustable for viewing vicinities of the vehicle during driving forward and during driving in reverse. One or more of the multiple mirrors are configured to be adjustable for viewing a blind spot. The system further includes a mirror control module coupled to the right and left mirror units and used for adjusting mirror orientations and storing one or more settings of the mirror orientations customized for the one or more users, respectively. The setting for each of the one or more users includes a first subset for driving forward and a second subset for driving in reverse, and the mirror control module controls the mirror orientations according to the second subset for driving in reverse upon detecting that the gear is in reverse.
