- FIG. The vehicle image 31a and the aforementioned guide line image 35a are displayed.
- the guide line image 35a that is, the guide line 35 shown in FIG. 3 (d) is parallel to the direction in which the vehicle goes straight and retreats in step ((a direction inclined approximately 45 degrees with respect to the road direction).
- the positional relationship between the line 35 and the other vehicle 31 does not change. That is, even if the host vehicle 20 is located at the position B along the guide line 35 parallel to the position A and further away from the other vehicle 31, and the position B is set as the parking start position and the step ⁇ is started, The fact that the vehicle's left front corner is not likely to come into contact with the other vehicle 31 even if step 3 is executed only when the rectilinear retreat distance in step 2 becomes longer is that when the parking operation is started from position A Is the same.
- the ideal starting position A for parallel parking which does not come into contact with other vehicles 3 1 even after performing step 3, or the position B parallel to it, and the relationship between the guide line 35 and the size of the own vehicle 20 It is determined in advance from the size such as the turning radius. For this reason, the guide line image 35a is displayed anywhere on the monitor screen 36 when the host vehicle is moving straight back and forth in parallel with the adjacent vehicle in order to find the position to start step ⁇ of parallel parking. Whether to do so can be decided in advance.
- the guide line image 35a predetermined according to the size of the own vehicle is superimposed on the camera image on the monitor screen 36 as shown in FIG. Can be easily determined. That is, when the own vehicle 20 is moved straight back and back, and the guide line image 35a comes to a position deviating from the other vehicle image 31a, the position is determined by the position of the other vehicle 31 that is higher than the guide line 35. This indicates that the vehicle is in front, and that the host vehicle 20 does not contact the other vehicle 31 even when the parallel parking operation is performed.
- the guide line image 35a deviates from the other vehicle image 31a, turn the steering wheel to the left sometime and move backward until it is parallel to the guide line image 35a.
- the guide line image 35a is a fixed guide display (in the example shown in FIG. 4, the guide display always indicates the predetermined left diagonal backward direction of the own vehicle), when the own vehicle 20 starts rotating, However, it is not known whether or not the direction of the host vehicle 20 is parallel to the direction of the guide line image 35 a displayed on the monitor screen 36 before this rotation.
- step 2 is executed, and the host vehicle 20 goes straight back and forth until it reaches the position K.
- the vehicle trajectory 34 is displayed on the monitor screen 36, and the vehicle trajectory 34 and the side line 3 of the parking space 30 are displayed. It can be determined whether or not 2 has reached a predetermined distance.
- the vehicle reaches the position K turn the steering wheel to the right and turn backward until the roadside line 32 of the parking space 30 is parallel to the side surface of the vehicle 20. This completes parallel parking.
- the vehicle can be parked in parallel only by three operations, namely, the straight-back operation, the steering operation by turning the steering wheel to the left, and the steering operation by turning the steering wheel to the right. Parallel parking is easily possible.
- the guide line image shown in FIG. Although only the guide line image 35a corresponding to the line 35 is displayed on the monitor screen, in the present embodiment, in addition to this guide line image 35a, the position K (step An auxiliary guide line image that can accurately judge the optimal start position in (3) is also displayed.
- Fig. 5 In order to explain the guide display, only the predicted trajectory 40 when the steering wheel is turned to the right is shown only as follows: The guide display that supports parallel parking to the right is described below. This can be easily obtained by reversing the left and right. Then, a tangent line 41 of the predicted trajectory 40 is obtained, and a line 42 separated outward from the tangent line 41 by a predetermined distance d is obtained.
- the tangent 41 is, for example, a tangent at a point where the center line of the vehicle 20 and the predicted trajectory 40 intersect.
- the predetermined distance d is the distance d shown in FIG. 7D, that is, the distance between the left side surface of the vehicle and the roadside line 32 at the end of parallel parking.
- the angle formed by the line 42 with respect to the center line of the vehicle 20 is defined as H (in FIG. 5, the angle is shown as an angle with a straight line 44 along the left side of the vehicle body, which is parallel to the center line). Then, a line 45 inclined in the opposite direction by an equal angle to the line 44 is obtained, and a line 43 parallel to the line 45 and separated by a predetermined distance t forward is obtained.
- the position of the line 45 in the front-rear direction with respect to the own vehicle 20 is determined in the same manner as the guide line 35 in the first embodiment. That is, even if the steering wheel is turned to the left and the line 45 is parallel to the vehicle 20, and the steering wheel is turned to the right and the front of the vehicle 20 is swung to the left, 20 is defined as a line indicating the boundary of a range that never touches another vehicle 31.
- a line 43 that is separated from the line 45 by a distance t as a margin is obtained, and this line 43 is used instead of the guide line 35 in the first embodiment.
- the lines 42 and 43 determined in advance as described above are guide lines, and the guide lines 42 and 43 are obtained when the camera 21 captures images.
- the line images 42a and 43a are superimposed on the monitor screen 36 shown in FIG.
- the parking operation using the guide line image 43a is performed in the first embodiment. This is the same as the example using the guide line image 35a, and is used as a guide for knowing the operation start position in Step I.
- step 1 is started (FIG. 7 (a)), and the steering wheel is turned to the left to retreat. I do.
- the position at which the operation in step ⁇ was completed was determined by visually confirming that the own vehicle was tilted by about 45 degrees with respect to the road, for example.c.
- step 1 ends and step ⁇ starts. That is, the steering wheel is returned straight, and the vehicle goes straight back. This retreat is performed until the guide line image 32a matches the image of the roadside line 32 (Fig. 7 (c)). When they match, the end position of step (2), that is, the start position of step (3).
- step 3 When it comes to the starting position of step 3, turn the steering wheel to the right as shown in Fig. 7 (d) and move backward. During this retreat, the front of the host vehicle 20 swings largely to the left and approaches the other vehicle 31, but its trajectory is behind the line 43 shown in Fig. 7 (a). However, there is no risk of contact with the other vehicle 31.
- step 1 is performed immediately after the guide line image 43 a shown in FIG. 6 deviates from the other vehicle image 3.1 a. Even if it starts, contact is avoided with plenty of time.
- step 3 The reverse of this step 3 is performed until the direction of the vehicle 20 becomes parallel to the roadside line 32. At the end position of step 3, a gap of the distance d described above remains between the vehicle 20 and the roadside line 32.
- step 3 that is, the position where the vehicle 20 and the roadside line 32 are parallel to each other is directly determined visually, but a guide line image that assists this determination is displayed on the monitor screen 3. 6 can also be displayed.
- a guide line image 5 corresponding to two straight lines 50 arranged behind the host vehicle 20 in parallel with the host vehicle 20 and slightly wider than the vehicle width. 0a is superimposed on the monitor screen 36 of FIG.
- this Reference numeral 24a shown in FIG. 10 is an image of the rear pump 24 shown in FIG.
- the guide on the monitor screen 36 displays a straight line in real space (the straight line 50 shown in Fig. 11) due to the effect of lens distortion.
- the line image 50a becomes a curve.
- the monitor screen 36 becomes difficult to see. Therefore, a device for correcting lens distortion is provided in the control means 22 shown in FIG. 1 so that a straight guide and a straight line such as the road side line 32 are also straight lines on the monitor screen. It should be corrected so that it is displayed as.
- the present embodiment by superimposing and displaying the guide line image 42 a in addition to the guide line image 43 a on the monitor screen, not only the start position of step 1 but also the step 3 The start position can also be easily determined. Furthermore, because the predetermined distances t and d described in Fig. 5 are provided, even if the driver concentrates on the rear obstacle during parallel parking, the driver can easily avoid contact with other vehicles or road shoulders while parking ahead. Becomes
- the guide display is limited. There is an effect that the operation can be performed quickly and easily, and the driving operation based on the operation can be simplified, and a stable parallel parking operation can be performed.
- FIG. 9 is an explanatory diagram of a guide line according to the present embodiment.
- guide lines 51, 52 Is used.
- the guide line 51 is a line that is parallel to the guide line 43 and indicates a position behind the guide line 43 by a required distance from the length of the vehicle 20.
- Guide line 5 2 that connects guide line 4 3 and guide line 5 1 0 is a line indicating the vehicle width from the roadside line 32 necessary for parking.
- the monitor screens 3 1 and 5 2 a would be obtained when the guide lines 51 and 52 are captured by the camera 21 of FIG. Is superimposed on the display.
- Steps 1 and 3 are limited to the reverse operation at the maximum steering angle, the trajectory of the host vehicle in these parking steps is uniquely determined.
- the relationship with the parking position is also uniquely determined. That is, when the start position of step (2) is determined, the position at which parking can be finally performed is an area that passes when the vehicle is moved in parallel with the guide line 43. Therefore, when the guide line 51 is a straight line, the guide line 51 is parallel to the guide line 43.
- the vehicle positions x, y, z, shown in Fig. 9 (d) indicate the positions that the vehicle 20 will eventually reach when it parks itself according to steps (3) and (3).
- Position X is the optimal final parking position, while positions y and z are the final parking positions when the straight-ahead retreat distance in step ⁇ ⁇ ⁇ is incorrect. Even if the straight-ahead retreat distance at step 2 is incorrect, the final parking position is shifted parallel to the guide line 51, so that the other vehicle 53 on the rear side can use this guide. As long as it is behind the line 51, it will not touch other vehicles 53 behind it.
- step 2 When the start position of the vehicle is determined by the guide line 43, when the guide line 51 overlaps the other vehicle 53 behind, it is understood that the guide line 51 comes into contact with the other vehicle 53 behind.
- the position of the host vehicle 20 is adjusted so that the other vehicle 53 behind is behind the guide line 51 so as not to collide with the other vehicle 53 behind.
- the adjustment it can be seen that when the guide line 43 overlaps the other vehicle 31 parked ahead of the parking space, the vehicle comes into contact with the other vehicle 31.
- FIG. 9 (a) it is determined whether or not the vehicle 20 can be parked with respect to the space 30 while the other vehicles 3 1 and 5 3 are parked.
- the own vehicle 20 is retracted in parallel with the other vehicle 3 1 that is parked, and when the other vehicle 31 in front comes before the guide line 43, the other vehicle 53 in the rear is guided by the guide line 51. It can be determined by whether or not it is later. That is, in the monitor screen 36 in FIG. 8, the image of the other vehicle 31 is displayed on the guide line image 43a. If the image of the other vehicle 53 does not overlap with the guide line image 51a, it is determined that the vehicle 20 can be parked in the parking space 30 between the other vehicles 31 and 53. Can be done.
- the host vehicle 20 is stopped in parallel with the other vehicle 3 1 that is parked in front of the parking space, and the vehicle 20 goes straight forward and backward. It is possible to accurately determine whether or not the vehicle can be parked in the target parking space.
- the guide line images 51 a and 52 a are displayed as dotted lines, but, for example, an inner region surrounded by the guide line images 51 a and 52 a May be displayed by adding a color, etc., and need not be displayed as a line.
