Problems solved by technology
As the operation of modern vehicles becomes more automated (i.e., able to provide driving control with less and less driver intervention), due to the reduction of human manipulation of the vehicle, feedback to vehicle systems such as the steering system may be delayed or missed Diagnosis of Possible Degraded Conditions

The invention discloses methods and systems for steering system integrity testing. In one embodiment, a method for steering system integrity testing includes positioning the vehicle with the second traction wheel within a first constraint; applying mechanical load to the first traction wheel; receiving data corresponding to a steering system operating condition; positioning the vehicle with the first traction wheel within a second constraint; applying mechanical load to the second traction wheel; receiving data corresponding to a steering system operating condition; positioning the vehicle with the first and second traction wheels on respective first and second friction surfaces; applying mechanical load to the first and second traction wheels; receiving data corresponding to a steering system operating condition; transmitting the data to a processor; and determining, via the processor, a health status of the steering system based on the data.
Description
technical field [0001] The present disclosure relates generally to a steering system of a vehicle, and more particularly to methods and systems for monitoring a vehicle steering system to determine the health of the steering system. Background technique [0002] The vehicle's steering system allows the driver to steer the vehicle's front wheels. The steering system may be an electric steering system that uses an electric motor to provide steering assistance to a driver of the vehicle, thereby reducing the driver's effort in steering the vehicle. [0003] In some cases, components of a vehicle's steering system may become electrically and mechanically sacrificed or degraded due to rough road surfaces, component wear and tear, or other factors. As the operation of modern vehicles becomes more automated (i.e., able to provide driving control with less and less driver intervention), due to the reduction of human manipulation of the vehicle, feedback to vehicle systems such as t...
