Abstract
Vehicle ride can be improved using perception based suspension control on a vehicle. A computing system on the vehicle may receive a map of a road surface. The computing system may identify a trajectory of the vehicle relative to the road surface, and determine if a deformation exists in a track of one of the vehicle tires. The deformation may include a depression and/or a raised portion from the road surface. The computing system may calculate an adjustment to make to one or more suspension system components to negate or minimize the effects of the vehicle traveling over the deformation or roughness of the road, and may send an instruction to adjust the suspension components accordingly. Additionally, or alternatively, the computing system may determine that the deformation may be avoidable, in whole or in part, and may cause the vehicle to maneuver around the deformation.
