Abstract
In an embodiment, a method of determining whether to trigger an event based on data blocks having status data includes electronically receiving the data blocks over a channel, performing a data integrity check on the data blocks to determine whether a particular data block has a transmission fault, calculating a received error metric based on performing the data integrity check, and disabling an event trigger if the received error metric crosses a first error threshold.
Claims29
A method of determining whether to trigger an event based on data blocks having status data, the method comprising:
- electronically receiving the data blocks over a channel;
- performing a data integrity check on the data blocks to determine whether a particular data block has a transmission fault;
- calculating a received error metric based on performing the data integrity check;
- and
- disabling an event trigger if the received error metric crosses a first error threshold.
A method of determining whether to trigger an event based on sensor data blocks, the method comprising:
- receiving sensor data blocks over an interface;
- performing a data integrity check on the sensor data blocks to determine whether a particular sensor data block has a transmission fault;
- calculating a received error metric based on performing the data integrity check;
- and
- disabling an event trigger if the received error metric exceeds a first error threshold.
A method of determining whether to deploy an airbag based on sensor data blocks, the method comprising:
- receiving sensor data blocks over an interface;
- performing a data integrity check on the sensor data blocks to determine whether a particular sensor data block has a transmission fault;
- calculating a received error metric based on performing the data integrity check;
- disabling airbag deployment if the received error metric exceeds a first error threshold;
- and
- re-enabling the airbag deployment after disabling the airbag deployment if the received error metric decreases below a second error threshold.
A system for triggering an event based on sensor data, the system comprising:
- a reception interface configured to be coupled to a sensor transmission channel, and configured to receive sensor data blocks;
- a data integrity check block configured to determine if the sensor data blocks contain data errors;
- an error probability monitor configured to determine a received error metric based on data errors detected by the data integrity check block;
- and
- an event triggering block configured to
- disable an event trigger if the received error metric is greater than a first a first error threshold,
- re-enable the event trigger if the received error metric falls below a second error threshold after the event trigger has been disabled, and
- trigger the event if the sensor data blocks meets event triggering criteria, and if the event trigger is enabled.
A method of determining whether to trigger an event based on sensor data blocks, the method comprising:
- receiving sensor data blocks over an interface from a plurality of sensors;
- performing a data integrity check on the sensor data blocks to determine whether a particular sensor data block has a transmission fault;
- calculating a received error metric based on performing the data integrity check;
- and
- increasing a transmission rate of a first of the plurality of sensors based on the received error metric.
