Alert: Email notifications sent to alert the recipient(s) that an incident occurred on a vehicle.
Anti-lock Braking System (ABS): An automobile safety system that allows the wheels on a motor vehicle to maintain tractive contact with the road surface according to driver inputs while braking, preventing the wheels from locking up (ceasing rotation) and avoiding uncontrolled skidding.
Company Administrator: A user who has administrative rights to perform tasks such as adding and editing filters.
Company Representative: A user who can use the Critical Event Reporting software to perform tasks such as incident searches, but who does not have administrative rights.
Following Time Violation (FTV): A CER trigger event that is generated when the calculated value for following time falls below a specified threshold set by a company administrator. The following time calculation takes into account the following distance reported by a Collision Warning System and the vehicle speed reported by speed sensors.
Forward Collision Warning (FCW): A CER trigger event that is generated when Collision Warning System sensors on the truck issue an in-cab alert indicating that a forward collision is imminent.
Global group: A group of assets (vehicles and drivers) recognized by CER and other Services Portal applications. Users are associated with global groups and permissions can restrict users to seeing data only for assets belonging to global groups with which the user is associated. Global groups are used to filter the vehicles whose incidents appear in lists and reports.
Hard braking: A CER trigger event defined as: "the vehicle is traveling at more than 20 MPH and its speed decreases by at least 9 MPH per second for three consecutive calculations, each made 0.2 seconds apart." Activation of the ABS also constitutes a hard braking event.
Hard braking deceleration rate: The deceleration rate that triggered the incident. The rate must exceed the hard braking threshold of 9 MPH/sec.
Incident: An event that results in the collection of data from the mobile for storage, display, and alerting back to CER to help customers reconstruct accidents.
Lane Departure Warning left/right (LDW): A CER trigger event that is generated when sensors on the truck indicate a lane departure that has not been signalled by the driver.
Lane Departure Warning disabled: A CER trigger event that is generated when the driver disables the lane departure warning system.
Manual trigger: A CER trigger event that is generated when the driver initiates the manual trigger. Typically this is when an accident occurs.
Minimum speed: The minimum speed in MPH for the hard braking events for which you want to be alerted.
NOC: Network Operations Center
HOS: Hours of Service
Performance Monitoring(tm): Provides trip recording, vehicle diagnostics, vehicle speed and RPM to monitor driver performance.
Stability control warning: A CER trigger event that is generated by anti-rollover sensors on the truck.
UA: Unified address. The ID associated with the mobile device on the truck.
