Curb detection for vehicle parking
First Claim
Patent Images
1. A vehicle comprising:
- wheel speed sensors;
a curb detector configured to compare a first yaw rate to a reference yaw rate to physically detect an actual location of a curb based on measurements from the wheel speed sensors; and
a steering control system configured to;
before detecting the curb, maneuver the vehicle into a parking space based on an estimated location of the curb; and
in response to detecting the curb, maneuver the vehicle into the parking space based on the actual location of the curb.

Abstract
Systems and methods for curb detection for parking are disclosed. An example vehicle parking assist system includes a processor and memory. An example program stored in the memory is configured to move a vehicle using a set of maneuvers to park the vehicle in a parking space based on an estimated location of a curb. The example program is also configured to compare a first yaw rate to a reference yaw rate to detect when the vehicle contacts the curb. Additionally, the example program is configured to move the vehicle using an adjusted set of maneuvers based on an actual location of the curb.

13. A method comprising:
-
moving a vehicle along a calculated path to park the vehicle in a parking space based on an estimated location of a curb; comparing, with a processor, a first yaw rate to a reference yaw rate to detect when a wheel of the vehicle physically contacts the curb based on measurements from wheel speed sensors; and changing the calculated path to account for on an actual location of the curb. - View Dependent Claims (14, 15, 16, 17)
