For rolling stock, which produce a tractive effort utilizing adhesion between their wheels and the rail, adhesion performance is very important. To improve this, the development of driving force control systems which attain optimal use of adhesion is necessary. So, adaptive creep control (ACC), which controls driving force at the maximum point of friction force using creep speed and its differential value, was developed. For the application of ACC to chopper-type electric cars, two systems were developed. In one, speed censors were equiped on all driving axles (ACC-V), and in the other, motor voltages were used (ACC-E). ACC-V and ACC-E were tested using a test car. The test results showed that ACC-V and ACC-E could control driving force near the maximum point of friction force, and attained about a 25% larger mean vehicle acceleration under wet rail conditions, compared with a conventional system.
