Problems solved by technology

However, in this structure, even if the vehicle is running in a forward gear (at a speed higher than the above-mentioned threshold value) before the abnormal activation of the control device, the automatic transmission will be switched to the neutral state after the abnormal activation of the control device, Therefore, there is a possibility that the driver's drivability may decrease, such as the driver feels that the driving force is lost.
Therefore, it is desirable to maintain the state before the reset when the control device is reset. However, in the above configuration, when the control device is reset while the vehicle is running, it cannot be determined whether it is a neutral state or a forward range state.

Embodiment Construction

[0022] Embodiments of the control device will be described with reference to the drawings. In the following description, "drive connection" refers to a state in which two rotating members are connected so that a drive force can be transmitted. This concept includes a state in which two rotating members are connected to rotate integrally and a state in which two rotating members are connected in a manner capable of transmitting a driving force via one or more transmission members. This kind of transmission member includes various members (shafts, gear mechanisms, belts, chains, etc.) coupling device, etc.).

[0023] Such as figure 1 As shown, the control device 30 is a control device for controlling the automatic transmission 1 including the parking lock mechanism 10 . Furthermore, the control device 30 is a control device that controls the shift-by-wire system of the automatic transmission 1 in accordance with a selection command of the shift position when the shift positio...

Abstract

A hydraulic control device (32) is configured so that when the supply of electric power to said hydraulic control device (32) is cut off while a power transmission state is being implemented in a forward range in a transmission mechanism (50), a specified gear, which is a predetermined forward gear, is formed in the transmission mechanism (50). When the supply of electric power to a control device(30) is cut off during vehicle travel and the control device is restarted and a specified gear is formed in the transmission mechanism (50), said control device (30) controls an automatic transmission (1) in a forward range.

Description

technical field [0001] The invention relates to a control device for a shift-by-wire mode. Background technique [0002] As a control device of the shift-by-wire system, a device described in Japanese Patent Application Laid-Open No. 2013-104463 (Patent Document 1) is known. The control device described in Patent Document 1 has an automatic transmission having a parking lock mechanism as a control object, and operates according to a command from a gear selection device whose selection of a shift position is not specified by a mechanical position of an operated part. However, sometimes the control device is abnormally started (restarted) due to being reset due to a momentary interruption of the power supply of the control device, etc. The mechanical position of the operated part specifies the shift position selected before the abnormal start. In addition, in the parking lock device 50 described in Patent Document 1, the brake plate 62 is located at both the position where t...
