Abstract

Arrangements relate to providing assistance during reverse parking of a vehicle. A rear environment of the vehicle can be detected for one or more objects located in the rear environment. If an object is detected in the rear environment, a visual alert of the detected object can be provided. The visual alert can be provided in a rear interior portion of the vehicle. The visual alert can be substantially aligned with the location of the detected object in the rear environment. Thus, a rearward-looking driver can be visually alerted of the presence of the detected object in the rear environment.
