Abstract
A control apparatus of an automatic transmission has a gear change control section for detecting an on signal of an OD off switch and performing OD off control, an OD off automatic release setting section for specifying whether or not an OD off state is to be automatically released, an automatic release set state detection section for detecting the automatic release set state in the OD off automatic release setting section, and a first OD off automatic release section for automatically releasing the OD off state when the vehicle becomes a predetermined deceleration state or vehicle stop state if the on signal of the OD off switch and the automatic release set state in the OD off automatic release setting section are detected.
Claims10
A control apparatus of an automatic transmission comprising:
- a gear change control section which detects an on signal of an overdrive (OD) off switch and performing OD off control;
- an OD off automatic release setting section which allows a user to set whether or not an OD off state is to be automatically released;
- an automatic release set state detection section which detects the automatic release set state in the OD off automatic release setting section;
- and
- an OD off automatic release section which automatically releases the OD off state, when a vehicle becomes a predetermined deceleration state or the vehicle is in a stop state and the on signal of the OD off switch and the automatic release set state in the OD off automatic release setting section are detected, irrespective of an ignition state of the vehicle.

- an automatic release set state detection section which detects the automatic release set state in the OD off automatic release setting section;
- an OD off automatic release section which automatically releases the OD off state, when a vehicle becomes a predetermined deceleration state or the vehicle is in a stop state and the on signal of the OD off switch and the automatic release set state in the OD off automatic release setting section are detected;
- and
- a vehicle speed detection section which detects vehicle speed and is connected to the OD off automatic release section,
- wherein when the vehicle speed detected by the vehicle speed detection section becomes equal to or less than a predetermined value, the OD off automatic release section automatically releases the OD off state.
