VEHICULAR TRAVELING CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a vehicular traveling control system capable of preferably activating a brake in line with a decelerating manipulation performed on a manipulation pedal in a configuration in which the one manipulation pedal is used to control acceleration or deceleration of a vehicle and activate plural types of brakes.SOLUTION: A traveling control system switches a proportion of an engine brake or a regeneration brake and a proportion of a friction brake to the whole of a request braking force, which is dependent on a manipulation quantity of one manipulation piece, according to whether a behavior of a vehicle that is traveling is in a stable state or an unstable state or has a high possibility of entering the unstable state in the future.SELECTED DRAWING: Figure 4
