To provide a travel control device for an automobile, restraining ineffectual acceleration/deceleration by controlling the speed of own vehicle based on both speed of a preceding vehicle and a following distance to achieve a fuel consumption improvement and also achieving elimination of driver's discomfort by ineffectual acceleration/deceleration.SOLUTION: A travel control device in the present invention is mounted to an automobile equipped with a front recognition apparatus, a driving system and a speed meter, and comprises: a first target acceleration computation part computing a first target acceleration for making a following distance close to a target inter-vehicle distance on the basis of the distance between a preceding vehicle and own vehicle acquired by the front recognition apparatus, and an own vehicle speed acquired by the speed meter; a second target acceleration computation part computing a second target acceleration for controlling the own vehicle acceleration based on the preceding vehicle speed acquired by the front recognition apparatus and the own vehicle speed acquired by the speed meter; a target acceleration deciding part for deciding the slower one of the first and second target accelerations as the target acceleration; and a control part controlling the driving system so as to achieve the target acceleration.SELECTED DRAWING: Figure 3
【課題】本発明の目的は、先行車両の加減速と車間距離の双方に基づいて自車両の加減速を制御することで、無駄な加減速を抑制し燃費向上を実現するとともに、無駄な加減速による運転者の違和感の解消を実現する自動車の走行制御装置を提供することにある。【解決手段】本発明の走行制御装置は、前方認識装置と駆動系と速度計を備えた自動車に搭載され、前方認識装置が取得した先行車両との車間距離と、速度計が取得した自車両速度に基づいて、車間距離を目標車間距離に近づける第一目標加速度を演算する第一目標加速度演算部と、前方認識装置が取得した先行車両速度と、速度計が取得した自車両速度に基づいて、自車両加速度を抑制する第二目標加速度を演算する第二目標加速度演算部と、第一目標加速度と第二目標加速度の何れか小さい方を目標加速度とする目標加速度決定部と、目標加速度を実現するように駆動系を制御する制御部と、を有するものとした。【選択図】図3
