The invention relates to interlocks for file cabinets and the like which generally prevent more than one drawer from being opened at a given time. The interlocks include a cable which is changeable from a slack condition to a taut condition. In the taut condition, the interlocks prevent the associated drawer from being opened. In the slack condition, the interlock allows the associated drawer to be opened. The interlocks may be used in conjunction with a lock that selectively changes the tension in the cable from a slack condition to a taut condition and vise versa. The interlocks may be constructed to exert a tension on a cable that is independent of the pulling force exerted on a locked drawer. Alternatively, the interlocks may be constructed to exert a force on the cable that is a small fraction of the pulling force exerted on a locked drawer.

A classification determining unit determines classification of a stationary object that is detected by a stationary object detecting unit. In a case where it is determined that the stationary object is another vehicle, a judgment condition easing unit enlarges a margin area that is used when determining the need for collision avoidance support. When the margin area is enlarged, the probability for a user's own vehicle to interfere with the margin area increases. Stated otherwise, it becomes easier for a collision avoidance determining unit to determine that the collision avoidance support is needed.
