Abstract:
1. A travel controller which controls the travel of a vehicle, the travel controller comprising: a road information acquisition unit which acquires road information of a scheduled travel route; a temporary target travel control pattern generation unit which generates a temporary target travel control pattern of the scheduled travel route on the basis of the road information; an engine state transition section estimation unit which estimates an engine state transition section where the state of an engine transits from a stop state to a start state or from the start state to the stop state on the basis of an engine output for attaining a target speed in the temporary speed pattern when the vehicle travels using the temporary target travel control pattern; a speed difference calculation unit which calculates variation in engine output resulting from limiting engine output, wherein the engine output is limited when the state of an engine transits in the engine state transition section, and calculates a speed difference resulting from variation in engine output; a target travel control pattern generation unit which corrects the temporary target travel control pattern on the basis of the speed difference to generate a target travel control pattern; and a travel control unit which performs travel control on the basis of the target travel control pattern.
