  • Patent number: 5738605
    Abstract: An anti-hunt transmission control strategy for controlling an automatic transmission so as to prevent the occurrence of a shift hunting condition. The control strategy determines a learned vehicle inertia as well as road load torque and expected torque in an upshift gear. A projected post shift acceleration is predicted based on the expected torque, road load torque and inertia of the vehicle. If vehicle speed and throttle position are within an allowable shift zone and if the predicted post shift acceleration exceeds a threshold value, the vehicle automatic transmission is allowed to upshift. Otherwise, should the predicted post shift acceleration not exceed the threshold value, an upshift is prevented.
