Installation for transportation by trains made of different types of carriages

Abstract: An installation for transportation by trains made up of carriages able to move first within a network of their own, which may be a rail system, and then in an ordinary automotive vehicle network. Passengers pass from one network to another whilst remaining in the same carriage, thus abolishing loss of time due to halts for loading. Carriages circulate in the first network according to the principle of segmented trains, then as convoys, and lastly as individual vehicles.

Method for controlling acceleration and deceleration of a traction motor

Abstract: Speed control system method for a traction motor in which speed setting signals are compared with the actual speed of the vehicle to provide a signal for selecting a value of the derivative of the setting acceleration, this derivative being integrated by an integrator taking the constraints relative to the integral into account, and the resultant setting acceleration serving to control the motor.
