Abstract:
1. A control apparatus for a vehicle having means for setting a target driving shaft torque according to operation by a driver of said vehicle or to an environmental operating condition ahead of said vehicle, means for detecting a vehicle speed of said vehicle, means for controlling a transmission ratio of a transmission of said vehicle using said target driving shaft torque and the vehicle speed, means for detecting operation of an accelerator pedal by the driver, and means for detecting a deceleration rate of said vehicle, wherein when the operation of the accelerator pedal is detected as zero, an actual deceleration rate of said vehicle in a predetermined time period after the operation of the accelerator pedal becomes zero is detected, wherein the transmission ratio of said transmission is controlled by using at least the detected actual deceleration rate, wherein said apparatus determines a target critical rotational speed at an input shaft of said transmission, wherein a target transmission ratio is determined according to at least the target critical rotational speed, wherein said vehicle has a switch for manually setting said target critical rotational speed, and wherein said apparatus controls said transmission ratio by using said target critical rotational speed set by said switch.
