Patent number: 11754471Abstract: Techniques and methods for testing a structural integrity of a vehicle. For instance, the vehicle may use suspension(s) to lift corners of the vehicle, where lifting the corners creates a torsion force in the body of the vehicle. The vehicle may then use sensor(s) to determine a deflection that is caused by the torsion force. Next, the vehicle may determine a stiffness associated with the body of the vehicle using the force that was applied to lift the corners and the deflection. After determining the stiffness, the vehicle may compare the stiffness to a baseline stiffness in order to determine whether there is a problem with the structural integrity of the vehicle. The baseline stiffness may include s standard stiffness or be based on a previous test of the vehicle. If the vehicle determines that there is no problem, then the vehicle may continue to operate as intended.Type: GrantFiled: April 30, 2021Date of Patent: September 12, 2023Assignee: Zoox, Inc.Inventors: Johannes Edren, Ahditya Melkote, Keith David Myers
