Abstract

PROBLEM TO BE SOLVED: To early detect an obstacle such as a cut-in vehicle from an adjacent lane in high-speed traveling of a vehicle by forward increasing the warning generating range in relation to the obstacle with the increase of the vehicle speed of a driver's own vehicle, and increasing the lateral width with the transfer from the medium speed to the high speed. SOLUTION: A laser beam feeding and receiving part 3 forward radiates pulse-like laser beams from a light feeding part from a driver's own vehicle. The radiated laser beams are reflected by an obstacle such as a traveling vehicle existing ahead of the driver's own vehicle and received by a light receiving part of the laser beam feeding and receiving part 3. An obstacle detecting part 2 detects the distance to the obstacle such as the forward vehicle on the basis of the transmission time required from the time when the laser feeding and receiving part 3 feeds the light beams to the time when it receives the reflected. The direction (azimuth) of the obstacle as viewed from the driver's own vehicle as well as the distance from the driver's own vehicle to the obstacle are detected with lateral scanning of the radiation laser beams.

That is, when the vehicle is running at a low speed, a flat collision warning area that is reduced in the forward direction and expanded in the horizontal direction is set as illustrated by the dotted line in FIG.

When the vehicle speed of the host vehicle further increases and the vehicle is driven at a high speed, in order to enable early detection of an interrupted vehicle from an adjacent lane, the vehicle is further expanded forward as shown in FIG.

FIG. 3 is a conceptual diagram showing an example of the front length and the width of the collision warning area which are changed according to the speed of the host vehicle. However, the length in front of the vertical axis is drawn on a scale several tens of times larger than the horizontal width. The length of the collision warning area monotonically increases as the vehicle speed V increases. The length of the collision warning area corresponds to a so-called safe inter-vehicle distance that varies depending on the vehicle speed, and increases at an accelerating rate as the vehicle speed increases.
In contrast, the width of the collision warning area for obstacles is
It is set to be substantially constant during low-speed running, to decrease once in the middle speed range, and to increase again at high speed.

Note that the alarm generation area for an obstacle illustrated in FIG. 1 does not always coincide with the irradiation range of the laser beam or the receivable range of the laser beam reflected by the obstacle. That is, for example, the irradiation range of the laser beam by mechanical scanning and the receivable range of the reflected laser beam are set to a sufficiently wide range that can cover the alarm generation area at the time of running at all of low speed, medium speed, and high speed. It is also possible to fix in advance and set an alarm generation area that is changed according to the vehicle speed within the irradiation range and the light receiving range.

However, in consideration of interference due to interference with other vehicles and extension of the life of the laser diode, the minimum range that can cover the alarm generation area for an obstacle that is changed according to the vehicle speed is as follows. It is desirable to set the irradiation range of the laser beam and the receivable range of the reflected beam. Therefore, as a preferred example, the irradiation range of the laser beam is changed by changing the range of the angle of the mechanical scanning in the width direction of the own vehicle, and the bias to the laser diode is set in the forward direction of the own vehicle. This is performed by changing the amount of light emission according to the change in voltage.

Preferably, when an alarm is issued for the obstacle, a laser beam emitted from another vehicle or its reflected light, or a reflected light from another vehicle or a reflector other than a pedestrian such as a corner reflector. Is removed by the data processor 1 under appropriate selection rules, for example, removal of false or unnecessary obstacles that may appear by avoidance of detection and avoidance of detection.

Further, in order to discriminate a corner reflector or the like from other obstacles such as a vehicle, the distance of the reflector changes monotonously with respect to the scanning angle as disclosed in Japanese Patent Application Laid-Open No. 5-159199. In this case, this reflector is judged as a reflector on a curved road shoulder and is excluded from obstacles.
As disclosed in Japanese Patent No. 312954, the fixed reflector on the road shoulder and the vehicle reflector have different deflection characteristics, or as disclosed in Japanese Patent Laid-Open No. Various known techniques, such as estimating the position and judging that the light is reflected from the vehicle when the estimation is incorrect, can be used together.

Further, according to the present invention, when the own vehicle approaches a curve, the vehicle shifts from a high-speed running state to a medium-speed running state, so that the width of the alarm generation area is reduced, and the corner reflector and the oncoming vehicle are wasted. Alarm is less likely to occur. However, more preferably, the curvature of a curve detected by an accelerometer such as a steering angle sensor or a yaw rate sensor, or detected from navigation map information as disclosed in Japanese Patent Application Laid-Open No. 5-196736. Depending on the situation, appropriate corrections such as changing the direction of the laser head and the alarm generation area, or cutting out a part of the alarm generation area near the inside of the curve or a part of the distant part outside the curve, etc. Done.

In the above, the configuration in which the width of the alarm generation area is enlarged at the time of low-speed running has been exemplified. If necessary, as shown by the dotted line in FIG. 3, the width at the time of low-speed running is almost the same as that at the time of medium-speed running. It can be configured to keep the value. In addition, instead of gradually increasing the width at a high speed while increasing the vehicle speed, a configuration in which the width is increased stepwise from a certain vehicle speed may be adopted.
