Crash and Rollover Detection
In addition to the longitudinal acceleration sensor and lateral acceleration sensor the central sensor also incorporates rollover detection. Rollover detection consists of a rate of yaw sensor and two low-g sensors. One low-g sensor measures in the Y direction, the second sensor in the Z direction.
Additional airbag sensors are mounted in the B-pillars. These each consist of a longitudinal acceleration sensor and a transverse acceleration sensor.
Together with the transverse acceleration sensor in the central sensor, the transverse acceleration sensors serve to detect side-on crashes. Pressure sensors are also used in the front doors to detect side-on crashes.
Together with the longitudinal-acceleration sensor in the central sensor, the longitudinal-acceleration sensors serve to detect front-and rear-end crashes.
There are two airbag up-front sensors for front-end crash detection. They are located on the front area of the engine side members.
