PROBLEM TO BE SOLVED: To provide a travel control device and method of an electric two-wheel vehicle for performing braking force control, driving force control and cornering control with the grip force of front and rear wheel tires within the stability limit or threshold of a friction circle graph.SOLUTION: An EV controller 48 includes: friction circle diameter setting means 83 for acquiring road information and vehicle travel information to set tires in the current traveling state and a friction circle diameter or a friction circle graph in a road surface state; friction circle graph calculation means 85 for estimating which position of the friction circle graph the gripping force of the tires in the current traveling state is present at; and output adjustment means 86 for outputting a command value to an integrated control device 88 when the estimated gripping force of the tires exceeds the stability limit or threshold of the friction circle graph. In the EV controller 48, the integrated control device 88 performs braking force control, driving force control and cornering control in parallel, and constantly performs traveling control of the gripping force of the front and rear wheel tires within the stability limit or threshold of the friction circle graph.SELECTED DRAWING: Figure 5
