Abstract
A vehicle, a vehicle parking assist system, and a parking method, is provided. A powertrain and a steering system may be operated to guide the vehicle into a parking location to complete a drive cycle based on a default tire radius, a tire angular velocity acquired during a drive cycle in response to a steering angle of the steering system exceeding a threshold value, and wheel and GPS vehicle speeds for the drive cycle.
Claims16
A vehicle comprising:
- a powertrain;
- a steering system;
- and
- a controller programmed to operate the powertrain and steering system to guide the vehicle into a parking location to complete a drive cycle based on a default tire radius, a tire angular velocity acquired during the drive cycle in response to a steering angle of the steering system exceeding a threshold value, and wheel and GPS vehicle speeds for the drive cycle.
1 more element
A vehicle parking assist system comprising:
- a parking sensor configured to identify a parking location for a vehicle relative to a curb;
- and
- a controller programmed to guide the vehicle into the parking location in response to a park assist request based on a yaw rate, GPS vehicle speed, wheel speed, and initial tire radius such that changes in tire radius away from the initial tire radius during a preceding drive cycle do not cause a distance between a parked location of the vehicle and the curb to be greater than a predetermined threshold distance.
A parking method comprising:
- guiding, by a controller, a vehicle into a parked position relative to a curb to complete a drive cycle based on a yaw rate, GPS vehicle speed, wheel speed, track width, and default tire radius such that changes in tire radius away from the default tire radius during the drive cycle do not cause a distance between the parked position and the curb to be greater than a predetermined threshold distance.
