Traffic jam recognizing device

Abstract

Abstract PURPOSE:To eliminate the need for the collection of the data of a traveling condition for a long time, accordingly, to recognize a traffic jam in a short time and to speedily correspond to the traffic jam by detecting the alternative repetition of smooth acceleration and smooth deceleration. CONSTITUTION:A smooth acceleration deciding means compares the acceleration, which is detected by an acceleration detecting means, of a vehicle with a prescribed value determined as the acceleration at a normal traveling time, and outputs a smooth accelerating signal when the detected acceleration is smaller than the prescribed value. On the other hand, a smooth deceleration deciding means compares the deceleration, which is detected by a deceleration detecting means, of the vehicle with a prescribed value determined as the deceleration at the normal traveling time, and outputs a smooth decelerating signal when the detected deceleration is smaller than the prescribed value. A jam deciding means decides the traffic jam when the smooth accelerating signal and smooth decelerating signal are alternatively outputted with a prescribed frequency or above. Thus, the traffic jam is recognized in a short time without collecting the data of the traveling condition for a long time and a recognized result can be reflected on the control, etc., of an automatic transmission.
