Patent ID: 7813851

Claim:
A misalignment detection sensor assembly for a motor vehicle comprising: a forward-looking sensor package having a housing and a forward-looking sensor, the forward-looking sensor having a sensing direction along a first axis X RAD ; and an inertia sensor fixed to the housing, the inertia sensor configured to sense acceleration along a second axis, the second axis having a fixed, non-parallel relationship with respect to the first axis X RAD ; and a signal processor in electrical communication with the inertia sensor, the signal processor configured to receive an acceleration signal from the inertia sensor and calculate a misalignment angle between the first axis X RAD and a forward axis X CG , the forward axis X CG being parallel to a direction of motion of the sensor assembly, wherein the inertia sensor is further configured to sense acceleration along a third axis X SEN , the third axis X SEN being orthogonal to the second axis and parallel to the first axis X RAD .
