Abstract:
A motor vehicle, comprising:shift manipulating means for establishing a selected one of an automatic shift mode in which an optimum gear position of an automatic transmission is automatically set based on a running condition of the vehicle, and a manual shift mode in which a gear position of the automatic transmission is changed according to a shift command operation of a driver;shift control means for changing the gear position of the automatic transmission based on an operated state of said shift manipulating means;target speed setting means for setting a target vehicle speed to which a vehicle speed is controlled under constant-speed cruise control;actual vehicle speed detecting means for detecting an actual vehicle speed of the motor vehicle;constant-speed cruise control means for controlling an engine of the vehicle so that the actual vehicle speed detected by said actual vehicle speed setting means becomes equal to the target vehicle speed set by said target vehicle speed setting means; andcanceling means for canceling an operation of said constant-speed cruise control means when said shift manipulating means is operated to switch from the automatic shift mode to the manual shift mode, and the shift command operation is performed by the driver, while the vehicle is running under constant-speed cruise control by the constant-speed cruise control means,wherein said shift manipulating means has a hold position for holding a gear position in which the transmission is placed at a point of time when the shift manipulating means is operated to the hold position to establish the manual shift mode, andwherein said shift control means inhibits a change of the gear position and causes the constant-speed cruise control means to continue constant-speed cruise control, when said shift manipulating means is operated to switch from the automatic shift mode to the manual shift mode, and is placed in said hold position after switching.
