Post collision restraints control module
First Claim
Patent Images
1. A restraints control module (RCM) for a vehicle that has at least one impact sensor comprising:
- a memory device for storing a deployment time of a deployment event;
a comparator comparing said deployment time with a fault time and determining whether said fault time corresponds with said deployment time; and
a controller electrically coupled to said memory device and said comparator, said controller determining when to deploy a restraint, storing said deployment time, and storing in said memory device a fault time corresponding to said deployment time, said fault time indicative of said fault within a component selected from at least one of the RCM and the at least one impact sensor; and
an indicator electrically coupled to said controller and indicating when said deployment time corresponds with said fault time.

Abstract
A restraints control module (RCM) for a vehicle is provided including a memory device. The memory device stores a deployment time of a deployment event. A controller is electrically coupled to the memory device and deploys a restraint in response to a collision signal and stores the deployment time in the memory device. A method of time stamping and indicating a deployment event within an automotive vehicle, having a RCM, is also provided.

4. A restraints control module (RCM) for a vehicle that has at least one impact sensor comprising:
-
an indicator; a memory device for storing a deployment start time of a deployment event; and a controller electrically coupled to said indicator and said memory device, said controller determining when to deploy a restraint and storing said deployment start time and duration in said memory device; said controller storing a fault time in said memory device and signaling said indicator when said fault time corresponds to said deployment start time and duration, said fault time indicative of a fault within a component selected from at least one of the RCM and the at least one impact sensor. - View Dependent Claims (5, 6, 7)
