Title: (EN) Steering apparatus for vehicle
(ZH) 车辆用转向装置
Abstract: front page image
(EN) There is provided a vehicle steering device capable of executing a steer-by-wire (SBW) mode for steering wheels by a steering mechanism arranged with mechanical disconnection from a steering device. The vehicle steering device includes: a coupling mechanism capable of making a mechanical connection between the steering device and a steering shift mechanism; and an SBW control unit for controlling the steering shift mechanism in the SBW mode according to the operation amount of the steering device and sets the coupling mechanism in the connected state to switch to the SBW backup mode when the SBW mode cannot be executed. The coupling mechanism is in a disconnected state during electric connection and in a connected state during electric disconnection. The SBW control unit checks whether the SBW can be executed upon engine start and checks whether the SBW mode can be continued during engine operation on a steady basis. With this configuration, it is possible to surely activate the SBW backup system when the system has failed.
(ZH)

本发明提供一种可执行利用断开与操纵装置的机械连接而设置的转向机构对车轮进行转向的线控转向(SBW)模式的车辆用转向装置。具备:可机械连接操纵装置和转向机构之间的连接机构;和在SBW模式时基于操纵装置的操作量控制转向机构,并在不可执行SBW模式时使连接机构处于连接状态并转换为SBW后备模式的SBW控制部。连接机构在通电时处于切断状态,在非通电时处于连接状态。SBW控制部在发动机起动时检查是否可执行SBW模式,且在发动机工作中总是检查是否可继续执行SBW模式。通过这样,在系统故障时等能够可靠地使SBW后备系统工作。
