Abstract

A power-up sequencing apparatus for successively energizing a plurality of associated subsystems in a host system, including a series of interconnected sequencing circuits, each sequencing circuit interconnected with a subsystem and including first switching means responsive to an initial system power-up for disabling its associated subsystem; second switching means responsive to an initial system power-up for suppressing the start command to the next sequencing circuit in the series; and third switching means responsive to a start command for operating the first switching means to enable its associated subsystem and for operating the second switching means to introduce a start command to the next sequencing circuit in the series.

Claims

1. A power-up sequencing apparatus for successively energizing a plurality of associated subsystems in a host system, comprising:

a series of interconnected sequencing circuits, each said sequencing circuit interconnected with a subsystem and including;

first switching means, responsive to an initial system power-up, for disabling its associated subsystem;

second switching means, responsive to an initial system power-up, for suppressing the start command to the next sequencing circuit in the series; and

third switching means, responsive to a start command, for operating said first switching means to enable its associated subsystem and for operating said second switching means to introduce a start command to the next sequencing circuit in the series.

2. The power-up sequencing apparatus of claim 1 further including time delay means for delaying arrival of said start command at said third switching means.

3. In a vehicle having drive wheels, a drive motor, a steering motor and control modules for operating said motors, a power-up sequencing apparatus for successively energizing a plurality of associated subsystems in a host system, comprising:

a series of interconnected sequencing circuits, each said sequencing circuit interconnected with a subsystem and including;

first switching means, responsive to an initial system power-up, for disabling its associated subsystem;

second switching means, responsive to an initial system power-up, for suppressing the start command to the next sequencing circuit in the series; and

third switching means, responsive to a start command, for operating said first switching means to enable its associated subsystem and for operating said second switching means to introduce a start command to the next sequencing circuit in the series.

4. The power-up sequencing apparatus of claim 3 further including time delay means for delaying arrival of said start command at said third switching means.
