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, in response to a steering angle of the steering system exceeding a threshold value, 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, and wheel and GPS vehicle speeds for the drive cycle.
1 more element
A vehicle comprising:
- an engine;
- a steering system;
- a parking sensor configured to identify a parking location for a vehicle relative to a curb;
- and
- a controller programmed to, in response to a park assist request, operate the engine and the steering system to guide the vehicle into the parking location 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.
2 more elements
A vehicle comprising:
- a controller programmed to operate a steering system to guide the vehicle into a parked position relative to a curb 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 a drive cycle do not cause a distance between the parked position and the curb to be greater than a predetermined threshold distance.
