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.
Claims4
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.
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.
