Abstract

A drive control device for a vehicle including an engine, a clutch connecting or disconnecting a power transmission path between the engine and a wheel, and a transmission changing a speed of rotation of the engine and transmitting the rotation to the wheel, includes: a coasting control unit controlling free-run coasting in which the vehicle coasts while the engine is stopped by disconnecting the power transmission path during traveling and neutral coasting in which the vehicle coasts while the engine is autonomously operated by disconnecting the power transmission path during traveling. A first lower limit value of a transmission fluid temperature in the free-run coasting or a transmission fluid temperature related value allowing estimation of the transmission fluid temperature is higher than a second lower limit value of a transmission fluid temperature in the neutral coasting or a transmission fluid temperature related value allowing estimation of the transmission fluid temperature.
