Abstract:
1. A control device of a vehicle having a power train including a power source, a transmission coupled to said power source and a fluid coupling arranged between said power source and said transmission, comprising: a detector configured for detecting a preference of a driver about deceleration of the vehicle when said power source is in an idle state; and a controller configured for controlling said vehicle, wherein said controller controls at least one of an output of said power source and an operation state of said fluid coupling based on said detected preference, wherein said detector detects whether the driver preference is for allowing rapid deceleration, and when the driver has said preference for allowing rapid deceleration, said controller controls said power source to provide the output to be smaller than that provided when said driver does not have said preference, and wherein said power source is an engine and an electric motor, and said motor can receive the power from the engine to generate electric power, and said controller controls a rotation speed of said engine in the idle state such that the output of said engine is set to correspond to a limit value determined by the control of the rotation speed of said engine in said idle state when said engine output determined according to said preference is lower than said limit value, and said motor uses, as power for electric power generation by said motor, a surplus output of the engine produced by controlling said engine output to correspond to said limit value.
