1. A vehicle control system comprising:
- a controller arranged to select an optimal mode adapted to a driving point of a vehicle from an optimal mode map of defining a plurality of running modes of the vehicle, to detect a generation of a mode transition in the optimal mode map, and to hold a current running mode selected before the transition for a holding time period when the generation of the mode transition is detected.

Abstract
A vehicle control system is comprised of a controller which is arranged to select an optimal mode adapted to a driving point of a vehicle from an optimal mode map of defining a plurality of running modes of the vehicle, to detect a generation of a mode transition in the optimal mode map, and to hold a current running mode selected before the transition for a holding time period when the generation of the mode transition is detected.

10. A vehicle control system comprising:
-
a transmission comprising a planetary gearset whose rotating elements are connected to an internal combustion engine, at least one motor and an output, an engine clutch through which a rotating element of the planetary gearset is connected to the engine, and an engagement element which is capable of engaging one of the rotating elements except for the rotating elements connected to the engine and an output, the transmission being capable of producing a plurality of running modes by changing the engagement states of the engine clutch and the engagement element; and
a controller arranged to select an optimal mode adapted to a driving point of a vehicle from an optimal mode map of defining the running modes, to detect a generation of a mode transition in the optimal mode map, and to hold a current running mode selected before the transition, for a holding time period from the generation of the mode transition, when the generation of the mode transition is detected.

11. A method of controlling a hybrid vehicle, comprising:
-
selecting an optimal mode adapted to a driving point of the hybrid vehicle from an optimal mode map of defining a plurality of running modes;
detecting a generation of a mode transition in the optimal mode map; and
holding a current running mode selected before the transition for a holding time period when the generation of the mode transition is detected.
