Filling the Torque Hole in Automated Manual Transmissions (11 LU 87GA 3N46)
Popis:
A large US company is looking for development of a control system that can fill the torque hole during the upshift in a low-cost passenger car automated manual transmission (AMT) with a single shifting clutch.
They are interested in licensing, product acquisition, contract research, proof of concept leading to scale up to manufacturing, joint development, supplier agreement, etc.
Small cars to be sold in developing countries can benefit from automatic transmissions. However, conventional units can be costly in their current configuration with hydraulic pumps and sophisticated electronic control mechanisms to facilitate their performance. One approach to a lower-cost automatic transmission design with a low-cost actuator and a single shifting clutch to change gears. Inherent in these lower losses during the gear shift when the single clutch connecting the engine to the driveline is released. This loss, dubbed a torque hole, can significantly downgrade vehicle driveability. Alternative systems, such as dual clutch transmissions, feature more complex mechanical designs and consequently are more costly to manufacture.
Our client is seeking a control system that can provide torque assist during gear shifts in a low-cost automotive transmission. This system should be compact, low cost, energy efficient and not add significant mechanical complexity to the current single clutch automated manual transmission design. When a customer's vehicle decouples the engine from the driveline for an upshift, the system should provide appropriate instantaneous torque to the vehicle output shaft to fill the torque hole. Once the upshift is complete and the transmission clutch relocks, the torque assist should end accordingly and the vehicle can return to its normal driving mode. The transient of the torque hole filling should result in a shift quality comparable to that of a conventional automatic transmission.
Possible approaches might include, but are not limited to:
-Secondary power source/energy storage for torque assist
-Smart mechanism design to create a secondary power path from the engine
-Faster actuation technologies for forks and clutches
-Other unique approaches.
The following approaches are not of interest:
-Computational model or "paper" studies with no hardware demonstrated.
Technical Specifications / Specific technical requirements:
The successful technology will:
-Fill the torque hole with good drive-ability during the gear change event when the engine is disconnected from the driveline
-Maintain the fuel efficiency and cost performance of the original AMT
-Meet these requirements:
Maximum torque assist to the output drive shaft of 1600 to 1800 N.m (note that this translates to a torque assist at the input shaft of 150-200 N.m if in first gear)
Meet a cost target of less than US$250.00
Result in shift quality comparable to a conventional automatic transmission
Less than 0.5% reduction in overall fuel economy on an urban driving cycle
Maximum peak power output over 35 KW during upshifts
Compatibility with commercial AMT assembly process
Accuracy of the torque assist to be within 10% of the target value
Response time of the torque assist system ‹50 msec from command to 90% of the target value
Be serviceable.
