The present invention pertains to a vehicle travel control device, and is intended to optimize the conditions in which coasting control is executed. A vehicle travel control device is provided with a coasting control execution unit (51) capable of executing coasting control for blocking the transmission of motive power between an engine (10) and drive wheels (16L, 16R) to cause a vehicle (1) to coast, a distance•relative speed detection device (20) for detecting the headway distance and relative speed between the host vehicle and a preceding vehicle, a headway distance estimation unit (52) for estimating for estimating the headway distance between the coasting host vehicle and the preceding vehicle on the basis of the value detected by the distance•relative speed detection device (20), and a coasting execution determination unit (53) for determining whether or not coasting is possible on the basis of the headway distance estimated by the headway distance estimation unit (52), the coasting control execution unit (51) executing coasting control when coasting is determined to be possible by the coasting execution determination unit (53). |
