Chevrolet Cobalt Service & Repair Manual: Description
The VSES (Vehicle Stability Enhancement
System) adds an additional level of vehicle control to the EBCM (Electronic
Brake Control Module). The EBCM controls the system functions and detects
failures. Yaw rate is the rate of rotation about the vehicle's vertical
axis. The VSES is activated when the EBCM determines that the desired yaw
rate does not match the actual yaw rate as measured by the yaw rate sensor. |
The desired yaw rate is calculated
from measured steering wheel position, vehicle speed and lateral acceleration.
The difference between the desired yaw rate and actual yaw rate is the yaw
rate error, which is a measurement of oversteer or understeer. If the yaw
rate error becomes too large, the EBCM will attempt to correct the vehicle
yaw motion by applying differential braking to the left or right front wheel. |

In a deployment event, the sensing system sends an
electrical signal triggering a release of gas from the
inflator. Gas from the inflator fills the airbag causing the
bag to break out of the cover and deploy. The inflator,
the airbag, and related hardware are all part of the
airbag module.
