Abstract
An automatic transmission has an automatic shift mode and a manual shift mode. When an opposite manual operation is performed, during an automatic shift based on a shift map in the automatic shift mode, in an opposite direction opposite to the automatic shift or when the opposite manual operation is performed, during a forced shift performed regardless of the manual operation in the manual shift mode, in the opposite direction opposite to the forced shift, a control apparatus forbids a shift based on a first manual operation and permits a shift based on a second or subsequent manual operation in the opposite direction opposite to the automatic shift or the forced shift.
Claims6
A control apparatus for an automatic transmission provided with an automatic shift mode to perform an automatic shift based on a predetermined shift map and a manual shift mode to perform a shift based on a manual operation of a driver,
- the control apparatus being configured so that, when an opposite manual operation is performed, during the automatic shift based on the shift map in the automatic shift mode, in an opposite direction opposite to the automatic shift or when the opposite manual operation is performed, during a forced shift performed regardless of the manual operation in the manual shift mode, in the opposite direction opposite to the forced shift, the control apparatus forbids a shift based on a first manual operation in the opposite direction opposite to the automatic shift or the forced shift and permits a shift based on a second or subsequent manual operation in the opposite direction opposite to the automatic shift or the forced shift.
A control apparatus for an automatic transmission provided with an automatic shift mode to perform a shift based on a predetermined shift map and a manual shift mode to perform a shift based on a manual operation of a driver,
- the control apparatus being configured so that, when an opposite manual upshift operation is performed, during an automatic downshift based on the shift map in the automatic shift mode, in an opposite direction opposite to the automatic downshift or when the opposite manual upshift operation is performed, during a forced downshift performed regardless of the manual operation in the manual shift mode, in the opposite direction opposite to the forced shift, the control apparatus forbids an upshift based on a first manual upshift operation and permits an upshift based on a second or subsequent manual upshift operation.
