Apparatus for controlling automatic transmission of motor vehicle
First Claim
1. A shift control apparatus for an automatic transmission of a motor vehicle having an engine, including shift control means for selecting one of a plurality of gear position of the automatic transmission selectively in a first, normal shift control according to a predetermined first shift pattern or in a second shift control according to a predetermined second shift pattern, based on a driving condition of the vehicle, and automatically shifting the automatic transmission to the selected gear position, comprising:
- output control member release determining means for determining whether an output control member for controlling an output of said engine has been released;
return-to-normal determining means for determining whether a predetermined return-to-normal condition under which said shift control means resumes said first, normal shift control using said predetermined first shift pattern after said second shift control using said predetermined second shift pattern is satisfied, said return-to-normal condition causing the automatic transmission to be shifted up by said shift control means immediately after the normal shift control using the predetermined first shift pattern is resumed; and
return-to-normal permitting means for permitting said shift control means to resume the first, normal shift control when said output control member release determining means determines that said output control member has been released, after said return-to-normal determining means determines that the predetermined return-to-normal condition is satisfied.

Abstract
It is an object of the invention to provide a shift control apparatus which does not cause a vehicle driver to feel uncomfortable when shift control means resumes normal shift control using a predetermined shift pattern. Where return-to-normal determining means 105 determines that a condition or conditions under which the shift control means 102 resumes shift control using a MEDIUM MODE shift pattern is/are satisfied, return-to-normal permitting means 116 permits the shift control means 102 to resume the shift control using the MEDIUM MODE shift pattern when an output control member release determining means 108 determines that an accelerator pedal 58 has been released. In this arrangement, the driver does not feel uncomfortable even if the transmission is shifted up immediately after the shift control means 102 resumes the shift control using the MEDIUM MODE shift pattern.

11. A shift control apparatus for an automatic transmission of a motor vehicle, including shift control means for selecting one of a plurality of gear position of the automatic transmission selectively in a first, normal shift control according to a predetermined first shift pattern or in a second shift control according to a predetermined second shift pattern, based on a driving condition of the vehicle, and automatically shifting the automatic transmission to the selected gear position, comprising:
-
vehicle speed increase determining means for determining whether a running speed of said motor vehicle has increased; return-to-normal determining means for determining whether a predetermined return-to-normal condition under which said shift control means resumes said first, normal shift control using said predetermined first shift pattern after said second shift control using said predetermined second shift pattern is satisfied, said return-to-normal condition being likely to cause the automatic transmission to be shifted up by said shift control means immediately after the normal shift control using the predetermined first shift pattern is resumed; and return-to-normal permitting means for permitting said shift control means to resume the first, normal shift control when said vehicle speed increase determining means determines that said running speed of said motor vehicle has increased, after said return-to-normal determining means determines that the predetermined return-to-normal condition is satisfied. - View Dependent Claims (12, 15, 16, 17, 18)
