Abstract

A vehicle parking assist system includes at least one processor configured to establish communication with a parking automation system external to a vehicle to assist in a parking maneuver. The parking automation system includes at least one sensor to provide a measured distance value from an object to the vehicle. The processor is further configured to control a brake system of the vehicle based on the measured distance value via the sensor. The processor is further configured to control the vehicle to come to a stop based on the measured distance value being less than a first predefined threshold via the brake system.

First claim

What is claimed is:

1 . A vehicle parking assist system comprising:
a processor configured to,
establish communication with a parking automation system external to a vehicle and having at least one sensor providing a measured distance value from a detected object to the vehicle; and
in response to the measured distance value, control a brake system of the vehicle so that the vehicle comes to a stop based on the measured distance value being less than a first predefined threshold.

2 . The vehicle parking assist system of claim 1 , wherein the at least one sensor comprises a camera.

3 . The vehicle parking assist system of claim 2 , wherein the measured distance value is a distance from a wall of a garage to the vehicle, and the first predefined threshold is a calibrated distance so that the vehicle stops before contacting the wall of the garage.

4 . The vehicle parking assist system of claim 3 , wherein the processor is further configured to transmit to a display a value of the distance from the wall of the garage to the vehicle.

5 . The vehicle parking assist system of claim 1 , wherein the processor is further configured to receive a brake override request via input at a brake pedal sensor.

6 . The vehicle parking assist system of claim 1 , wherein the parking automation system is configured with a global system for mobile communications network to communicate with the processor.

7 . The vehicle parking assist system of claim 1 , wherein the processor is further configured to establish communication with a mobile device and to communicate with the parking automation system via the mobile device.

8 . The vehicle parking assist system of claim 1 , wherein the at least one sensor comprises a first garage sensor, a second garage sensor, and a third garage sensor.

9 . The vehicle parking assist system of claim 8 , wherein the processor is further configured to receive a sidewall distance value from at least one of the first garage sensor, second garage sensor and third garage sensor, and control an electrically assisted power steering system based on the sidewall distance value being less than a second predefined threshold.

10 . The vehicle parking assist system of claim 9 , wherein the sidewall distance value of a garage is a distance from a sidewall of the garage to the vehicle, and the second predefined threshold is a calibrated distance so that the vehicle turns via the electrically assisted power steering system before contacting the sidewall of the garage.

11 . The vehicle parking assist system of claim 10 , wherein the processor is further configured to transmit to a display a value of the distance from the sidewall of the garage to the vehicle.

12 . The vehicle parking assist system of claim 9 , wherein the processor is further configured to receive a steering wheel override request via input at a steering wheel sensor.

13 . A vehicle computing system comprising:
a processor in communication with a remote parking automation system (PAS) and configured to, control a brake system in communication with the processor based on a first distance value via a first sensor of the PAS being less than a first predefined threshold; and control a power steering system based on a second distance value via a second sensor of the PAS being less than a second predefined threshold.

14 . The vehicle of claim 13 , wherein the first distance value is a distance from a wall of a garage to the vehicle, and the first predefined threshold is a calibrated distance so that the vehicle stops before contacting the wall of the garage.

15 . The vehicle of claim 14 , wherein the processor is further configured to transmit to a display a value of the distance from the wall of the garage to the vehicle.

16 . The vehicle of claim 13 , wherein the second distance value of a garage is a distance from a sidewall of the garage to the vehicle, and the second predefined threshold is a calibrated distance so that the vehicle turns via the power steering system before contacting the sidewall of the garage.

17 . A computer-program product embodied in a non-transitory computer readable medium that is programmed for a vehicle processor and comprising instructions for:
establishing communication with a remote parking automation system having at least one sensor; receiving one or more distance values via the at least one sensor based on a detected object; and transmitting commands to a brake system and a power steering system of a vehicle based on the one or more distance values.

18 . The computer-program product of claim 17 , the non-transitory computer readable medium further comprising instructions for receiving a first distance value of a parking spot via the one or more distance values, and controlling the power steering system so that the vehicle turns based on the first distance value being less than a first predefined threshold.

19 . The computer-program product of claim 17 , the non-transitory computer readable medium further comprising instructions for receiving a second distance value of a parking spot via the one or more distance values, and controlling the brake system so that the vehicle stops based on the second distance value being less than a second predefined threshold.

20 . The computer-program product of claim 17 , the non-transitory computer readable medium further comprising instructions for transmitting to a display at least one of the one or more distance values and the commands transmitted to the brake system and power steering system.
