The present invention provides a vehicle travel device capable of preventing an increase in energy consumed during travel of a host vehicle when the distance between a preceding vehicle and a following vehicle becomes shorter during execution of autonomous acceleration/deceleration control. The vehicle traveling device (10) executes autonomous acceleration/deceleration control that starts coasting control when the distance from the vehicle traveling device (10) to the preceding vehicle (200) decreases and reaches a lower limit value, and starts acceleration control when the distance from the vehicle traveling device (10) to the preceding vehicle increases and reaches an upper limit value. The acceleration and deceleration of the host vehicle (100) are autonomously controlled so that the distance from the preceding vehicle is within a predetermined range. When a rear vehicle is present and the distance between a preceding vehicle and the rear vehicle is equal to or less than a predetermined distance during execution of the autonomous acceleration/deceleration control, the vehicle traveling device stops the autonomous acceleration/deceleration control and autonomously controls acceleration/deceleration of the own vehicle so that the distance from the preceding vehicle is maintained at a target distance.
本发明提供能够防止在自主加减速控制的执行中在前车与后车之间的距离变短时在本车辆的行驶中消耗的能量的增大的车辆行驶装置。车辆行驶装置(10)执行以下的自主加减速控制:在与前车(200)之间的距离减小而达到了下限值时开始滑行控制,在与前车之间的距离增大而达到了上限值时开始加速控制,由此,以使与前车之间的距离处于预定范围内的方式自主地控制本车辆(100)的加减速。车辆行驶装置在自主加减速控制的执行中,在存在后车且前车与后车之间的距离成为了预定距离以下时,停止自主加减速控制,以使与前车之间的距离维持为目标距离的方式自主地控制本车辆的加减速。
