CONTROL APPARATUS FOR HYBRID VEHICLE
First Claim
1. A hybrid vehicle control apparatus comprising:
- an engine;
an electric motor;
a holding element arranged between the engine and the electric motor to selectively connect and disconnect the engine and the electric motor to and from each other;
an automatic transmission arranged between the electric motor and a drive wheel;
a range position detecting device arranged to detect a range position of the automatic transmission selected by a driver; and
a controller configured to execute a control operation serving to stop the engine while also executing a slip control serving to lower a torque transfer capacity of the holding element upon a determination that a request to stop the engine has occurred while the engine is operating, the holding element is engaged, and the range position detecting device detects the automatic transmission in a non-driving range.

Abstract
A hybrid vehicle control apparatus is provided with an engine, an electric motor, a holding element, an automatic transmission, a range position detecting device and a controller. The holding element is arranged between the engine and the electric motor to selectively connect and disconnect the engine and the electric motor to and from each other. The automatic transmission is arranged between the electric motor and a drive wheel. The range position detecting device detects a range position of the automatic transmission selected by a driver. The controller executes a control operation serving to stop the engine while also executing a slip control serving to lower a torque transfer capacity of the holding element upon a determination that a request to stop the engine has occurred while the engine is operating, the holding element is engaged, and the automatic transmission is detected in a non-driving range.

8. A hybrid vehicle control method comprising:
-
detecting a range position of an automatic transmission selected by a driver in which the automatic transmission is coupled between an electric motor and a drive wheel; and executing a control operation serving to stop an engine that is selectively coupled to the electric motor by a holding element that selectively connects and disconnects the engine and to and from the electric motor while also executing a slip control serving to lower a torque transfer capacity of the holding element upon a determination that a request to stop the engine has occurred while the engine is operating, the holding element is engaged, and the automatic transmission is detected in a non-driving range.
