Abstract
When a driver returns a brake pedal on a climbing road, brakes of front wheels to which power is output from an engine with brakes of rear wheels being held are released (S140), and a throttle opening TH is gradually increased so that a rotation speed of the engine reaches a target rotation speed Ne* according to a road gradient θ (S180). When an outputtable torque Tem that can be output to the front wheels and the rear wheels becomes larger than a target torque Td* according to the road gradient θ, the brakes of the rear wheels are released (S240) to start a vehicle. This allows a smooth start of the vehicle on the climbing road. On the other hand, when a slip of the front wheels is determined before the outputtable torque Tem reaches the target torque Td*, the brakes of the front wheels are returned to the original state, climbing road start control is prohibited (S260 and S270), and a stopping state is held. This properly addresses the problem when the vehicle cannot smoothly start.
