Abstract
A car system and control method in which transmission shifting is controlled such that synchronizer damage is avoided. A state discrimination device detects or infers the state of each frictional surface of the synchronizers. A synchronizer for forming an intermediate transfer path is selected according to a parameter indicating the state of the frictional surface detected or inferred by the state discrimination device. Engine torque control reduces the engine torque according to a parameter indicating the state detected or inferred by the state discrimination device.
