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.

Claims

1. A vehicle parking assist system comprising:

a processor configured to;

communicate with a parking automation system external to a vehicle, the parking automation system having at least one sensor configured to provide a measured distance value from a detected object to the vehicle, wherein the at least one sensor comprises a camera; and

responsive to the measured distance value, control a brake system of the vehicle to stop the vehicle based on the measured distance value being less than a first predefined threshold.

2. The vehicle parking assist system of claim 1 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.

3. The vehicle parking assist system of claim 2, 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.

4. 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.

5. 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.

6. 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.

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

8. A vehicle parking assist system configured to communicate with a parking automation system having first, second, and third garage sensors external to a vehicle, at least one of which providing a measured distance value from a detected object to the vehicle, the vehicle parking assist system comprising:

a processor configured to;

establish communication with the parking automation system;

receive a sidewall distance value from at least one of the first, second, and third garage sensors;

control a brake system of the vehicle in response to the measured distance value so that the vehicle comes to a stop based on the measured distance value being less than a first predefined threshold; and

control an electrically assisted power steering system based on the sidewall distance value being less than a second predefined threshold.

9. The vehicle parking assist system of claim 8, 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.

10. The vehicle parking assist system of claim 9, 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.

11. The vehicle parking assist system of claim 8, wherein the processor is further configured to receive a steering wheel override request via input at a steering wheel sensor.

12. A vehicle computing system comprising:

a processor in communication with a remote parking automation system (PAS) having first and second sensors external to a vehicle, the processor configured to;

control a brake system based on a first distance value received from the first sensor being less than a first predefined threshold; and

control a power steering system based on a second distance value received from the second sensor being less than a second predefined threshold, wherein at least one of the first and second sensors comprises a camera.

13. The vehicle of claim 12, 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.

14. The vehicle of claim 13, 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.

15. The vehicle of claim 12, 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.
