[0037] figure 1 The configuration of a vehicle 10 including a control device according to the present embodiment is shown. A vehicle 10 according to the present embodiment is a hybrid vehicle in which an engine 11 and a motor generator (MG) 12 serve as drive sources. In addition, there may be more than one MG 12 . Also, vehicles to which the present invention can be applied are not particularly limited to hybrid vehicles. For example, the vehicle to which the present invention can be applied may be a vehicle using an engine as a driving source, an electric vehicle or a fuel cell vehicle using a motor generator as a driving source, or the like.

[0038] The vehicle 10 includes, in addition to an engine 11 and a motor generator (MG) 12 as a drive source, a shift control system for switching the gear position of a drive mechanism 70 constituted by a continuously variable transmission mechanism. This shift control system functions as an electronically controlled shift system th...

Abstract

When initial drive control for an actuator driving a shift switch mechanism is completed, a P-ECU determines whether an IG signal is received. In the case where the P-ECU has not received the IG signal at the time when the initial drive control is completed, the P-ECU temporarily keeps the actuator in a state where the initial drive control is completed. In the case where the P-ECU receives the IG signal in the period from completion of the initial drive control to the time when a predetermined time T2 has elapsed since completion of the initial drive control, the P-ECU executes P wall press control when the P-ECU receives the IG signal.

Description

technical field [0001] The present invention relates to control of a vehicle provided with a gear switching mechanism for switching gears of a transmission by driving an actuator. Background technique [0002] Conventionally, there is known a shift control system that uses electrical control to switch gear positions of an automatic transmission in accordance with an operation of a shift lever by a driver. As such a shift control system, Japanese Unexamined Patent Application Publication No. 2004-308752 (Patent Document 1) discloses a shift control system capable of appropriately controlling the rotation of an actuator using an encoder capable of detecting only relative position information. The above-mentioned actuator is used to drive a gear switching mechanism for switching gears of the transmission. [0003] The shift control system disclosed in Japanese Unexamined Patent Publication No. 2004-308752 performs control by rotating the actuator so that the wall of the lock p...
