A new computer-aided system for experiments on automatic transmissions has been developed. It consists of one general-purpose computer and three minicomputers in a concentrated hierarchical system. Each minicomputer controls several test cells via optical fiber cables. Compared with the conventional system which uses analog instruments (oscillograph recorders, etc.), the new system has the following advantages: (1) Efficient minicomputer processing of shift characteristics; (2) Fully automatic data acquisition (including shift characteristics) in tests of durability; and (3) Interactive data processing using a graphic terminal at each test cell. This system has been successful in the execution of performance and durability tests, and has saved a great amount of manpower and testing time.
