PROBLEM TO BE SOLVED: To provide a travel control device of a vehicle capable of improving all of fuel consumption of the vehicle, and driver's safety and drivability.SOLUTION: Inertia travel is executed (S9) when all of following inertia travel start conditions are satisfied (S8) that a vehicle (1) is in a key-on state and an engine (2) is operated (S2), an inertia travel switch (29) is on and an auxiliary brake switch (30) is off (S3), an accelerator is off and a brake is off in a D range (S4), within a prescribed road surface gradient range (S5), at a prescribed engine rotating speed or less (S6), within a prescribed vehicle speed range (S7), and an acceleration is a prescribed negative first threshold value (A1) or more, and a prescribed positive second threshold value (A2) or less.SELECTED DRAWING: Figure 2 |
