Vehicle park assist system and method for parking a vehicle using such system
First Claim
1. A method for parking a vehicle in a target parking space, the vehicle having a sensing system and a park assist system operatively connected thereto, the method comprising the steps of:
- scanning neighboring objects using a first sensor to determine if a target parking space is available for parking the vehicle, the neighboring objects including at least one object either in front of or behind the target parking space, wherein the first sensor provides an input signal to the park assist system;
scanning neighboring objects on the side of the vehicle opposite the target parking space using a second sensor to determine if a first clearance zone on the side of the vehicle opposite the target parking space is free of obstacles, wherein the second sensor provides an input signal to the park assist system;
scanning neighboring objects on the side of the vehicle opposite the target parking space using the second sensor to determine if a second clearance zone on the side of the vehicle opposite the target parking space is free of obstacles, wherein the second sensor provides an input signal to the park assist system;
using the park assist system to determine whether there is a sufficient slot length in which to park the vehicle;
if no obstacles are identified in the first clearance zone but an obstacle is identified in the second clearance zone, then using the park assist system to identify a first steering trajectory to avoid the obstacle and a second steering trajectory to park the vehicle into the target parking space; and
parking the vehicle in the target parking space along the first and second steering trajectories.

Abstract
A park assist system for parking a vehicle in a target parking space includes a first sensing system which determines whether there is a sufficient slot length in a target parking space in which to park the vehicle. A second sensing system determines whether an obstacle is located in a predetermined clearance zone on a side of the vehicle opposite the target parking space. A decision regarding whether to recommend parking the vehicle in the target parking space sensed by the first sensing system is dependent upon a determination that an obstacle located in the clearance zone may be avoided by executing a first steering trajectory provided by the park assist system in order to avoid the obstacle before executing a second steering trajectory provided by the park assist system in order to park the vehicle into the target parking space.

10. A method for parking a vehicle in a target parking space, the vehicle having a sensing system and a park assist system operatively connected thereto, the method comprising the steps of:
-
scanning neighboring objects using a first ultrasonic sensor to determine if a target parking space is available for parking the vehicle, the neighboring objects including at least one object either in front of or behind the target parking space, wherein the first ultrasonic sensor provides an input signal to the park assist system; scanning neighboring objects on the side of the vehicle opposite the target parking space using a second ultrasonic sensor to determine if a clearance zone on the side of the vehicle opposite the target parking space is free of obstacles, wherein the second ultrasonic sensor provides an input signal to the park assist system; using the park assist system to determine whether there is a sufficient slot length in which to park the vehicle; if an obstacle is identified in the clearance zone, then using the park assist system to identify a first steering trajectory to avoid the obstacle and a second steering trajectory to park the vehicle into the target parking space; and
parking the vehicle in the target parking space along the first and second steering trajectories.
