Abstract
Official abstract text for this publication.
In a vehicle equipped with an engine and a shift control mechanism that switches a shift position by rotating a detent plate with an electric actuator, an electronic control device is an electronic control device including a reference position learning unit that executes a learning of a reference position of the actuator that serves as a reference for switching the shift control mechanism by the actuator when a starting condition that is set in advance is satisfied, and includes a drive wheel rotation suppression unit that suppresses a rotation of a drive wheel of the vehicle while the learning of the reference position is being executed by the reference position learning unit.
First claim
Opening claim text (preview).
What is claimed is: 1 . A vehicle control device provided with, in a vehicle equipped with an engine and a shift control mechanism that switches a shift position by rotating a detent plate by an electric actuator, a reference position learning unit that executes a learning of a reference position of the actuator that serves as a reference for switching the shift control mechanism by the actuator when a starting condition that is set in advance is satisfied, the vehicle control device comprising a drive wheel rotation suppression unit that suppresses a rotation of a drive wheel of the vehicle while the learning of the reference position is being executed by the reference position learning unit. 2 . The vehicle control device according to claim 1 , wherein the drive wheel rotation suppression unit prohibits starting of the engine while the learning of the reference position is being executed by the reference position learning unit. 3 . The vehicle control device according to claim 1 , wherein the vehicle is provided with an automatic transmission between the engine and the drive wheel, and the drive wheel rotation suppression unit disengages a friction engagement device in the automatic transmission to disable power transfer while the learning of the reference position is being executed by the reference position learning unit. 4 . The vehicle control device according to claim 1 , wherein the vehicle is provided with a brake device that stops the rotation of the drive wheel, and the drive wheel rotation suppression unit blocks the rotation of the drive wheel by the brake device while the learning of the reference position is being executed by the reference position learning unit.
