Parking assist system

摘要

A parking assist system for a vehicle includes a camera and a display operable to display video images of an exterior scene derived from image data captured by the camera. A controller, when operating in a first or parking space locator mode, adds an overlay to the displayed video images. The overlay includes (i) a polygonal representation of the vehicle and (ii) a linear overlay extending along one side of the polygonal representation of the vehicle. The polygonal representation is offset behind and laterally from the vehicle. The controller is operable in the first mode while the vehicle is being driven by a driver of the vehicle and, with the overlay added to displayed video images, the driver maneuvers the vehicle to position the polygonal representation at a displayed target parking location. The linear overlay assists the driver in parking the vehicle at the target parking location.

1. A parking assist system for a vehicle, the parking assist system comprising:
a camera mounted at the vehicle and operable to capture image data representative of an exterior scene in a field of view of the camera; a display in the vehicle operable to display video images of the exterior scene derived from captured image data; a controller operable in a first mode and a second mode; wherein the controller, when operating in the first mode, adds a first overlay to the displayed video images of the exterior scene; wherein the first mode comprises a parking space locator mode; wherein the first overlay includes (i) a polygonal representation of a target parking position for the vehicle and (ii) a linear overlay; wherein the polygonal representation is offset a selected distance behind the vehicle and a selected distance laterally from the vehicle; wherein the controller is operable in the first mode while the vehicle is being driven by a driver of the vehicle; wherein, with the first overlay added to displayed video images, the driver maneuvers the vehicle to position the polygonal representation at a displayed target parking location; wherein the linear overlay extends along an outboard side of the polygonal representation and forward of the polygonal representation of a target parking position for the vehicle and rearward of the polygonal representation of a target parking position for the vehicle to assist the driver in parking the vehicle at the target parking location and to assist the driver of the vehicle in lining UP the vehicle to be parallel to the target parking location; wherein, when the vehicle is in a reverse gear, the controller is operable in the second mode, and wherein, when operating in the second mode, the controller adds a second overlay to the displayed image of the rearward scene; wherein the second overlay includes (i) a representation of a projected rearward path of the vehicle that is based on a steering angle of the vehicle and (ii) a representation of a target path for the vehicle; and said second overlay guiding the driver when maneuvering the vehicle towards and into the target parking location.
