A problem to maintain an acceptable level of dynamic loading a transmission and trolley-bus comfortablenesses in startup is considered. The problem is connected with growing a transmission backlash in continuous operation. The electric scheme and testing results for MAZ 103T trolleybus with proposed traction motor control system having intensity assignor of nonlinear transient characteristic are described. A structural diagram, algorithm and basic stages for development of adaptive control system are presented. Maximal transmission torque in transient process which induced by taking-up of the transmission backlash in startup is decreased in 1.8...2.4 times, number of torque oscillations in transmission - in 1.7...2 times, and maximal jerk - in 2.6...4.4 times. Acceleration dynamics indexes for the trolleybus are not substantially changed.
