Driving Assistance System

A driving assistance system automatically controls the longitudinal guidance of a motor vehicle according to a desired acceleration in driving situations characterized by multiple objects travelling level with each other in the same lane as and directly in front of the motor vehicle. A first acceleration controller determines a first desired acceleration based on a first desired distance from the first object. A second acceleration controller determines a second desired acceleration based on a second desired distance from the second object. The second acceleration controller also determines a third desired acceleration based on a third desired distance from a third object in a different lane and/or changing to the same lane. The desired acceleration is output based on the first desired acceleration, the second desired acceleration, and the third desired acceleration.
