Patent ID: 8483920

Claim:
A shift control device for an automatic transmission having a plurality of frictional engaging elements adapted to be selectively engaged to perform shift control, said shift control device comprising: computing means for computing the temperature of at least one of said frictional engaging elements to be engaged in shifting; comparing means for comparing the temperature computed by said computing means with a reference temperature; means for comparing a target gear position with a current gear position; upshift delaying means for delaying the timing of upshift using said frictional engaging element to be engaged by a predetermined time period when the temperature computed by said computing means is higher than said reference temperature and the target gear position is higher than the current gear position; and control means for when the target gear position is equal to or lower than the current gear position, maintaining the current gear position or allowing a downshift operation to be made in response to a request for downshift even if the temperature computed by the computing means is higher than the reference temperature.
