ECU executes a program including the steps of: detecting a mode input by a driver, detecting an accelerator opening degree TA to calculate an operation potential Pta based on the accelerator opening degree TA and an accelerator operation speed dTA, counting the number of times Pta exceeds a threshold value set according to a mode, as COUNT value, and learning a driver intention level in a sport direction when COUNT value is equal to or greater than the threshold value set according to a mode.
