Abstract
Methods and systems are provided for estimation of a ride height of a vehicle axle via a linear displacement sensor. In one example, a method may include, during motion of vehicle wheels, estimating a change in ride height of an axle based on a distance of axial movement between a first axle constant velocity universal (CV) joint and a differential unit.
Claims20
A method for a vehicle, comprising:
- during motion of vehicle wheels,
- estimating a change in ride height of an axle based on a distance of axial movement between a first axle constant velocity universal (CV) joint and a differential.
A method for a vehicle, comprising:
- during wheel travel, estimating a axial movement between a differential unit and a constant velocity universal (CV) joint coupling a half-shaft to the differential unit;
- retrieving a length of the half-shaft;
- and
- estimating a change in a vertical distance between a wheel end and a vehicle chassis as a function of the estimated linear distance and the retrieved combined length.
1 more element
A system for a vehicle, comprising:
- a controller with computer-readable instruction stored on non-transitory memory thereof that when executed enable the controller to:
- estimate a change in ride height of a vehicle axle relative to an initial ride height based on one or more of an estimated axial movement between a differential unit and a constant velocity universal (CV) joint coupling a half-shaft of the vehicle axle to the differential unit, an initial vertical distance between a plane of the differential unit and a wheel end, and a length of the half-shaft, the axial movement between a differential unit and the CV joint estimated via a linear displacement sensor coupled to the differential.
