    • A rear-wheel steering control apparatus includes a controller, which performs a first-order lag process. This process is equivalent to a first-order lag transfer function and is represented by a time constant matching loadage data from a rear-wheel stroke sensor and a proportional constant matching vehicle speed data from a vehicle speed sensor. The first-order lag process is performed on a front-wheel steering angle, obtained based on steering-wheel angle data from a steering-wheel angle sensor, to thereby set a target rear-wheel steering angle. Steering of rear wheels to the set rear-wheel steering angle is carried out with a degree of first-order response delay corresponding to the loadage. Thereby, traveling stability and forepart turning performance of a vehicle are improved in various loading and steering conditions.
    • 后轮转向控制装置包括执行一阶滞后过程的控制器。 该过程等同于一阶滞后传递函数,并且由来自后轮行程传感器的加载数据和来自车辆速度传感器的比例恒定匹配车辆速度数据的时间常数表示。 一阶滞后处理是在基于来自方向盘角度传感器的方向盘角度数据获得的前轮转向角进行的,从而设定目标后轮转向角。 后轮的转向到设定的后轮转向角度,以与加载相对应的一级响应延迟程度进行。 因此,在各种装载和转向条件下,车辆的行驶稳定性和前车转弯性能得到改善。

    • An equivalence determination system (10) according to this invention includes a specifying means (11) and determination means (12). The specifying means (11) specifies parts of respective electronic documents in a document database that are rarely modified manually. The determination means (12) determines whether the parts specified by the specifying means (11) match each other between a plurality of electronic documents, and when determining that the parts match each other, specifies that these documents are a plurality of similar electronic documents. An electronic document which cites part or all of another electronic document and is slightly modified can be quickly specified in the document database.

    • A policy normalizing means normalizes an entered security policy. Specifically, if the security policy does not include necessary items, the policy normalizing means compensates the security policy for the missing items by predefined values so that the security policy includes the necessary items. An behavior model generating means generates an behavior model representative of the operation of a network access controller based on the normalized security policy. In this event, the behavior model generating means generates an behavior model which is represented by a data structure that is not dependent on the type of the network access controller. A modifying means modifies the behavior model in accordance with a modification principle desired by an operator, and a configuration generating means generates configuration for the network access controller from the modified behavior model.
    • 策略规范化方式规范了输入的安全策略。 具体来说,如果安全策略不包括必要的项目,则策略规范化装置通过预定义值来补偿缺失的项目的安全策略,以便安全策略包括必要的项目。 行为模型生成装置基于归一化的安全策略生成代表网络访问控制器的操作的行为模型。 在这种情况下,行为模型生成装置生成由不依赖于网络访问控制器的类型的数据结构表示的行为模型。 修改装置根据操作者期望的修改原理修改行为模型,并且配置生成装置从修改的行为模型生成网络访问控制器的配置。
