| Abstract: |
An apparatus for stabilizing an active suspension system of an automotive vehicle is provided having a power source and a motor with a plurality of stator wires connected to the suspension unit for controlling the movement of the suspension. A controller is electrically connected to the motor and to the power source for developing current commands for input into the motor through the stator wires. The switch, electrically connected to the stator wires and the power source, connects the stator wires together in response to an interruption of the power source so that a high torque is developed in the motor for restraining the movement of the suspension unit.

What is claimed is:
1. An apparatus for controlling an electric active suspension for a motor vehicle having a plurality of wheels and a power source comprising:
- motor means connected to the suspension for controlling the movement of the suspension, said motor means having a plurality of stator wires;
- control means electrically connected to said motor means and to said power source for developing current commands for input into said motor means through said stator wires;
- switching means electrically connected to said stator wires and said power source for electrically connecting said plurality of stator wires together in response to a disconnection of said power source so that a high torque is developed in said motor means for restraining the movement of the suspension;
- wherein said switching means comprises a solenoid and plunger, said solenoid being operative to move said plunger upon energization thereof so that said stator wires are not electrically connected.
