Super Cruise accelerates or brakes the vehicle to maintain a selected following gap from a vehicle ahead, steers to maintain lane position, and on some models when offered, can perform both driver and system-initiated lane changes to pass slower traffic and to move from a lane that may be ending, while monitoring the driver’s head position and/or eyes in relation to the road to help ensure driver attention. These systems work together through “sensor fusion” to create a sensory field around the vehicle that assists in keeping it centered in the lane.
