Claim 0:
1. A control apparatus for a vehicle that includes a drive power source and an automatic transmission,
the control apparatus comprising:
a follow-up-running control portion configured to control an output of the drive power source so as to execute a follow-up running control for causing the vehicle to run following a preceding vehicle with a target inter-vehicle distance to the preceding vehicle from the vehicle without requiring an acceleration/deceleration operation by a driver of the vehicle; and
a shift control portion configured to change a gear ratio of the automatic transmission in accordance with a predetermined shifting condition,
wherein, during execution of the follow-up running control by the follow-up-running control portion, the shift control portion is configured to set a high fluid-temperature determination value, based on information relating to the preceding vehicle that affects an air flow rate that is a rate of flow of air to the vehicle, and
wherein, when a detected fluid temperature of the automatic transmission is not lower than the high fluid-temperature determination value, the shift control portion is configured to change the shifting condition depending on the fluid temperature such that a higher-speed gear position making the gear ratio lower is more frequently established in the automatic transmission than when the fluid temperature of the automatic transmission is lower than the high fluid-temperature determination value.
