Abstract: A housing for a battery pack of a vehicle is described herein. The housing includes a lateral baseplate, a central longitudinal baseplate, and at least one bracket. The lateral baseplate is configured to extend in a lateral direction of the vehicle and attach to a front cradle of the vehicle rearward of left and right body mount seats on the front cradle. The central longitudinal baseplate is configured to extend in a longitudinal direction of the vehicle and attach to the lateral baseplate. The at least one bracket is configured to connect the central longitudinal baseplate to the lateral baseplate and to form an angle with the lateral baseplate that is greater than 40 degrees.

Abstract: A trailer reverse assist system for a vehicle coupled to a trailer is provided. The trailer reverse assist system includes a park assist controller configured to receive a distance input from at least one rear distance sensor. The park assist controller is configured to determine a pitch angle of the trailer relative to the vehicle based on the distance input. An electronic power steering system is coupled to the park assist controller. The electronic power steering system is configured to adjust a hand wheel angle of the vehicle based on the pitch angle of the trailer.

Abstract: A method according to the present disclosure provides a ground connection between a first component and a vehicle body rail through a coating disposed on the vehicle body rail. The method includes inserting a grounding bushing into an aperture in a second component, positioning the second component between the first component and the vehicle body rail, placing the grounding bushing in contact with the first component, and inserting a fastener through the first component, through the grounding bushing, and into the vehicle body rail. The method further includes tightening the fastener to clamp the first component and the grounding bushing between a head of the fastener and the vehicle body rail and thereby cause the grounding bushing to pierce through the coating disposed on the vehicle body rail to provide the ground connection between the first component and the vehicle body rail.
