    • A control apparatus for a motor-driven power steering system of a motor vehicle controls the steering system such that a steering torque required to be applied by a driver is prevented from increasing abruptly or steeply even when generation of an assist torque applied to the steering system for assisting the driver in steering operation is to be stopped. The control apparatus includes an operation stop decision mechanism (111, 112, OR) for deciding whether or not an operation stop command is to be issued for stopping control operation for the motor-driven power steering system, a torque detecting mechanism (16, 113) for detecting a steering torque transmitted from an input shaft (21a) to an output shaft (21c) of a steering column (21) of the motor-driven power steering system, and an assist torque control mechanism (114, 116, 117, 118, 13) for updating an assist torque applied by an electric motor (20) to the output shaft (21c) with an assist torque control quantity determined on the basis of a detected torque value outputted from the torque detection mechanism (16, 113), wherein upon issuance of the operation stop command by the operation stop decision mechanism (111, 112, OR), the assist torque control mechanism stops application of the assist torque, provided that the detected torque value is lower than a predetermined value inclusive thereof.
    • 用于机动车辆的电动机动力转向系统的控制装置控制转向系统,使得即使在施加到转向系统的辅助转矩的产生时也防止驾驶员施加的转向转矩突然或陡峭地增加 用于辅助驾驶员的转向操作将被停止。 控制装置包括用于判定是否要发出用于停止对电动机动力转向系统的控制操作的操作停止命令的操作停止判定机构(111,112或OR),转矩检测机构(16,113 ),用于检测从所述电动机动力转向系统的转向柱(21)的输入轴(21a)到输出轴(21c)传递的转向转矩,以及辅助转矩控制机构(114,116,117, 用于根据从转矩检测机构(16,113)输出的检测转矩值确定的辅助转矩控制量,将由电动机(20)施加的辅助转矩更新到输出轴(21c) 其特征在于,在由所述动作停止判定机构(111,112,或OR)发出动作停止命令的情况下,辅助转矩控制机构停止施加辅助转矩,只要所述检测转矩值低于规定值 ve。

    • An electric power steering device includes: a fail-safe power relay (9a) and a motor relay (10a) for interrupting power supply to an electric-motor driving unit for driving an electric motor for applying an assist torque for steering performed by a driver; and a relay driving circuit (8a) including a switch (13a) connected in parallel to drive coils of the relays (9a and 10a) and a diode (16a). A target value of a relay-contact energizing current is lowered and the relays (9a and 10a) are gradually interrupted while an amount of current corresponding to a back surge generated when the relays are turned OFF is caused to flow back to the diode (16a) of the relay driving circuit (8a) in a normal relay-OFF operation, whereas the relays (9a and 10a) are quickly interrupted without operating the relay driving circuit (8a) in case of detection of an abnormality.
    • 一种电动助力转向装置包括:故障保护动力继电器(9a)和电动机继电器(10a),用于中断对电动机驱动单元的供电,用于驱动电动机,用于施加驾驶员执行的转向辅助转矩 ; 以及包括与所述继电器(9a和10a)的驱动线圈并联连接的开关(13a)和二极管(16a)的继电器驱动电路(8a)。 继电器触点通电电流的目标值降低,并且继电器(9a和10a)逐渐中断,同时使与继电器断开时产生的反向电涌相对应的电流量流回到二极管(16a ),而在检测到异常的情况下,继电器(9a和10a)在不操作继电器驱动电路(8a)的情况下快速中断。
