1. A control device comprising:
a route determining unit configured to determine a travelling route of a hybrid vehicle;
a travelling time estimating unit configured to, in a case where the travelling route includes an engine travelling restricted section and an engine requiring section, in which engine travelling is required, exists before the engine travelling restricted section in the travelling route, estimate a travelling time during which the hybrid vehicle travels from the beginning of the engine requiring section to the engine travelling restricted section;
a vehicle control unit configured to cause the hybrid vehicle to start an engine and start the engine travelling before the engine requiring section when the travelling time is shorter than a predetermined time; and
a point deciding unit configured to decide an engine travelling starting point in the travelling route, at which the vehicle control unit causes the hybrid vehicle to start the engine travelling when the travelling time is shorter than the predetermined time,
wherein the vehicle control unit is configured to cause the hybrid vehicle to start the engine travelling in response to the hybrid vehicle being located at the engine travelling starting point, and
wherein the point deciding unit is configured to decide the engine travelling starting point based on a subtracted time obtained by subtracting the travelling time estimated by the travelling time estimating unit from a time required for self-diagnostics of the hybrid vehicle.
