Abstract: Detecting off-zone crashes involving a vehicle using lateral acceleration values detected at locations within the vehicle. In one example method, an electronic processor receives a first acceleration value at a centerline of the vehicle from a first acceleration sensor of at least two acceleration sensors. The electronic processor also receives a second acceleration value at the centerline of the vehicle from a second acceleration sensor of the at least two acceleration sensors. The method also includes deriving, with the electronic processor, an approximate yaw acceleration at the centerline of the vehicle based on the first acceleration value and the second acceleration value. The method also includes comparing, with the electronic processor, the approximate yaw acceleration to a threshold and initiating, with the electronic processor, one or more actions in response to the yaw acceleration exceeding the threshold.
