Summary:

Increasing of automatic transmissions in passenger cars is based on pleasure of driving, smooth acceleration and easy operation makes the customer satisfaction. Challenges beyond 2020 is BS VI emission norms in India - a very tough goals on CO2& NOx reduction in Gasoline and Diesel vehicles. But its setback in lower fuel economy.To support and enhance fuel economy in Automatic transmissions as part of drivetrain technologies, this article discusses about the power losses in torque converters and experiments on the actual Automatic transmission (AT) vehicle on-road to understand the real city driving behavior in the aspects of gear utilization and gas pedal utilization throughout the entire traffic conditions. With that data research, slip area and slipping conditions is determined and clutch slip control is enabled at area in torque converter by ensuring that NVH parameters are not affected.The addition of the Lock-up Slip system add value in terms of "Joy of Driving" by providing a 2-3% improvement in fuel economy over the previous one
