An emergency in-lane steering assist system for use during a braking event comprises an object sensor for detecting the presence of an object in front of a motor vehicle and providing data from which the distance from the object to the motor vehicle is determined and a velocity sensor providing data from which the forward velocity of the motor vehicle is determined. A controller in communication with the object sensor and the velocity sensor calculates a Time to Contact (TTC) with the detected object and a steering system is responsive at least in part to operation by the controller. If the calculated TTC is less than a predetermined TTC, the controller provides a lateral steering input during the braking event to reduce the linear distance traveled by the motor vehicle relative to a predetermined path in the lane.
