Abstract
The invention disclosed provides a control system for an electric vehicle which automatically slows the vehicle during a turn and causes it to be increasingly slowed as the sharpness of the turn increases. The invention includes means for regulating the field excitation in accordance with a field regulating signal; means providing an armature current indicative signal; means providing a turning angle signal which is indicative of the turning angle of the vehicle; and a field excitation selector which receives the armature current indicative signal and the turning angle signal and then selects one or the other or a minimum reference value as the field regulating signal. The signal which produces the maximum field excitation is thus automatically selected. If a turning maneuver is being carried out, the turning angle signal increases until, at some point, the field excitation becomes a function of the steering angle and the vehicle is then automatically slowed as a function of the sharpness of the turn.
