Abstract
An ECU determines whether or not there is an abnormality (shift pattern abnormality) in a combination of shift signals provided from a shift position sensor. After occurrence of the shift pattern abnormality is determined, ECU determines whether or not a first condition that a shift pattern has changed into a normal pattern of a drive range, a second condition that a brake is ON and a vehicle is in a stop state is satisfied, and a third condition that an accelerator is OFF are satisfied. When occurrence of the shift pattern abnormality is determined, ECU stops generation of driving force of the vehicle and prohibits switching to the drive range. When ECU determines that the above-mentioned first to third conditions are satisfied after occurrence of the shift pattern abnormality is determined, ECU switches the shift range to the drive range indicated by the shift pattern.
