Abstract

A parking lot attendant robot is provided with a camera for capturing an image of an vehicle and a parking space, and a receiver from receiving vehicle information such as the steering angle, shift position and vehicle speed from the vehicle. Based on the knowledge of the position of the vehicle with respect to the parking space gained from the camera and the vehicle information received from the vehicle, the robot computes the optimum parking path which the vehicle should follow. The robot signals the motorist by a visual and/or auditory display and/or a hand signal as to how the steering wheel should be turned and which way the vehicle should move or stop for the vehicle to follow this parking path and to be successfully parked in the prescribed parking space.

Claims

1. A parking lot attendant robot system including a robot placed in a parking lot for giving guidance to a motorist who wishes to park an vehicle in a prescribed parking space defined within the parking lot, comprising:

a robot (1) provided with traveling means (1b, 14b) for moving about at least within the parking lot;

a control unit (13) for controlling various actions of the robot;

image capturing means (11, 12) for capturing at least an image of the vehicle (2) that is desired to be guided to the parking space (31) and identifying the position of the vehicle relative to the parking space;

parking path computing means (13) for computing a parking path which the vehicle should follow for the vehicle to be properly parked in the parking space according to the position of the vehicle identified by the image capturing means;

a vehicle information sensor (21–

24) for detecting vehicle information including a steering angle;

vehicle information transmitting means (25) for transmitting the vehicle information to the control unit;

guidance information generating means (13) for generating a guidance information including a target steering angle for the vehicle according to the vehicle information and the parking path computed by the parking path computing means; and

guidance information transmitting means (15, 14a;

18, 25, 27) for transmitting the guidance information from the control unit to the vehicle or a motorist driving the vehicle.

2. A parking lot attendant robot system according to claim 1, wherein the guidance information generating means is adapted to generate a movement guidance information indicating if the vehicle should move forward or backward and should stop, and the guidance information transmitting means is adapted to transmit the movement guidance information to the vehicle or a motorist driving the vehicle.

3. A parking lot attendant robot system according to claim 1, wherein the guidance information generating means is adapted to generate a position information indicating a relative position between the vehicle and prescribed parking space, and the guidance information transmitting means is adapted to transmit the position information to the vehicle or a motorist driving the vehicle.

4. A parking lot attendant robot system according to claim 1, wherein the image capturing means is carried by the robot.

5. A parking lot attendant robot system according to claim 1, wherein the control unit and guidance information transmitting means are carried by the robot whereby the robot is enabled to communicate directly with the vehicle and/or motorist.

6. A parking lot attendant robot system according to claim 5, wherein the guidance information transmitting means comprises a wireless transmitter carried by the robot for transmitting the guidance information and an onboard receiver carried by the vehicle adapted to receive and visually and/or auditorily display the guidance information.

7. A parking lot attendant robot system according to claim 5, wherein the guidance information transmitting means comprises a behavior generating unit and an actuator for moving a part of the body of the robot so as to signal the motorist.

8. A parking lot attendant robot system according to claim 5, wherein the guidance information transmitting means comprises a speech synthesis unit and a speaker for auditorily providing guidance information to the motorist.

9. A parking lot attendant robot system according to claim 4, wherein the image capturing means is adapted to capture an image of the parking space.

10. A parking lot attendant robot system according to claim 4, wherein the control unit is provided with a map of the parking lot and is adapted to identify the position of the robot on the map according to the captured image of the vehicle.

11. A parking lot attendant robot system according to claim 1, wherein the vehicle information further includes a shift position and traveling speed of the vehicle.
