Abstract: This disclosure relates to systems and methods for providing haptic feedback to a driver when aligning an electrified vehicle to charging equipment in preparation for charging events. Haptic feedback may be provided at the vehicle steering wheel to guide the driver on a correct travel path both laterally and longitudinally relative to the charging equipment. In some embodiments, the haptic feedback is provided at the steering wheel in the form of distinguishable pulsing patterns that alert the driver how the travel path should change for properly aligning the vehicle to the charging equipment. In other embodiments, the haptic feedback is provided in the form of tactile cues, such as making it more difficult for the driver to rotate the steering wheel in a direction that would render the vehicle less aligned to the charging equipment.

Abstract: An electrified vehicle, system, and method include an electric machine, a traction battery coupled to the electric machine, and a controller programmed to control wheel slip to provide high wheel slip to traverse deformable terrain, such as sand or loose soil, and lower wheel slip to avoid excessive soil removal beneath the wheels after detecting a vertical acceleration or heave event, such as after landing when driving over a jump or bump. When vehicle vertical acceleration exceeds a first threshold, and a ratio of a wheel angular acceleration to vehicle longitudinal acceleration exceeds a second threshold, the electric machine is controlled to limit wheel slip to a lower value that provides sufficient tractive force to maintain some forward motion. Otherwise, the electric machine is controlled to limit wheel slip to a higher value to accommodate higher vehicle speeds over the deformable terrain.
