CONTROL APPARATUS FOR AUTOMATIC TRANSMISSION HAVING FAIL-SAFE FUNCTION DURING VEHICLE STOP |
摘要 |
A control apparatus for an automatic transmission including a plurality of frictional elements each arranged to be engaged by receiving supply of an engagement pressure regulated by a solenoid, and being arranged to attain a plurality of gear stages by combination of engagements of the frictional elements, the control apparatus includes a failure occurrence sensing section configured to sense an occurrence of a failure-induced disengagement in one of the frictional elements based on a failure of one of the solenoids, based on an engine racing by a depression of an accelerator pedal in a state in which ranges other than a parking range and a neutral range are selected during a stop of a vehicle; and a command output section configured to output a limp home mode command to attain one of the gear stages to enable the vehicle to start.
