VEHICLE CONTROL SYSTEM A control system for an electrically powered vehicle has thyristors acting as choppers and switches in its power circuit. An on-hoard digital computer provides gating pulses to the thyristors to control traction and auxiliary motors in accordance with programs responding to operator, circuit and vehicle condition signals. The programs provide for vehicle start-up, shut-down, regular operation, limited operation and maintenance.
