Abstract
When a user performs an operation to switch from a forward range to a reverse range, an ECU switches an oil passage (referred to hereafter as a 'Bpressure supply source oil passage'), through which oil pressure is supplied to a brake, from a first oil passage to a second oil passage while engaging the same brake. At this time, in consideration of a response delay in the oil pressure in the second oil passage, the ECU switches the Bpressure supply source oil passage from the first oil passage to the second oil passage after a predetermined time α elapses from the point at which the user performs the forward-reverse switch operation (in other words, after waiting for the oil pressure in the second oil passage to reach a threshold pressure) rather than at the point at which the user performs the forward-reverse switch operation.
