Abstract

A parking assist system includes an image obtaining means for obtaining an image of a view from a vehicle, a displaying means for displaying the image obtained by the image obtaining means in a monitor display provided in the vehicle, an inputting means for inputting a target parking position, at which the vehicle is parked, on the monitor display, a detecting means for detecting a relative relationship between the vehicle and the target parking position, and a judging means for judging whether or not the vehicle can be parked at the target parking position based upon the relative relationship detected by the detecting means.

Claims

1. A parking assist system comprising:

an image obtaining means for obtaining an image of a view from a vehicle;

a displaying means for displaying the image obtained by the image obtaining means in a monitor display provided in the vehicle;

an inputting means for inputting a target parking position, at which the vehicle is parked, on the monitor display;

a detecting means for detecting a relative relationship between the vehicle and the target parking position; and

a judging means for judging whether or not the vehicle can be parked at the target parking position based upon the relative relationship detected by the detecting means.

2. A parking assist system according to claim 1, wherein the judging means judges whether or not the vehicle can be parked at the target parking position based upon a minimum turning radius of the vehicle.

3. A parking assist system according to claim 1, wherein the judging means judges whether or not the vehicle can be parked at the target parking position upon an ordinary-parking mode of the vehicle.

4. A parking assist system according to claim 2, wherein the judging means judges whether or not the vehicle can be parked at the target parking position upon an ordinary-parking mode of the vehicle.

5. A parking assist system according to claim 3, wherein the judging means judges whether or not the vehicle can be parked at the target parking position based upon an expected path generated in combination with a vehicle single turning movement and a vehicle straight movement upon the ordinary-parking mode.

6. A parking assist system according to claim 4, wherein the judging means judges whether or not the vehicle can be parked at the target parking position based upon an expected path generated in combination with a vehicle single turning movement and a vehicle straight movement upon the ordinary-parking mode.

7. A parking assist system according to claim 1, wherein the judging means judges whether or not the vehicle can be parked at the target parking position upon a parallel-parking mode of the vehicle.

8. A paring assist system according to claim 2, wherein the judging means judges whether or not the vehicle can be parked at the target parking position upon a parallel-parking mode of the vehicle.

9. A paring assist system according to claim 7, wherein the judging means judges whether or not the vehicle can be parked at the target parking position based upon an expected path generated in combination with a single turning movement to one side of the vehicle, a single turning movement to the other side of the vehicle, and a straight movement.

10. A parking assist system according to 8, wherein the judging means judges whether or not the vehicle can be parked at the target parking position based upon an expected path generated in combination with a single turning movement to one side of the vehicle, a single turning movement to the other side of the vehicle, and a straight movement.

11. A parking assist system according to claim 1, further comprising:

a warning means for warning an occupant a judgment result by the judging means.

12. A parking assist system according to claim 1, wherein the inputting means inputs the target parking position on the monitor display in response to operation of a target parking position inputting means.

13. A parking assist system according to claim 12, wherein the target parking position inputting means is a target parking position input switch touched by an occupant so as to input the target parking position at an intended position on the monitor display.

14. A parking assist system according to claim 6, wherein the judging means judges whether or not the vehicle can be parked at the target parking position when the expected path of the single turning movement has a radius being equal to or greater than the minimum turning radius of the vehicle and when a vehicle angle generated in response to the vehicle turning movement with the minimum turning radius is equal to or greater than a parking angle at the target parking position.

15. A parking assist system according to claim 3, wherein the ordinary-parking mode is selected when the vehicle is parked, for example, in a garage, in a parking space so as to be by the side of a vehicle parked in a parking space which is at a left or right hand side of the parking space that a driver wants to park in.

16. A parking assist system according to claim 7, wherein the parallel-parking mode is selected when the vehicle is parked parallel with a vehicle that has been parked in a parking space just in front of the parking space the driver wants to park in.
