The invention provides control of a steer-by-wire steering device. The microprocessor system comprises: a steering wheel actuator controller comprising a first microprocessor (107) and a second microprocessor (108); a front axle actuator controller comprising a first microprocessor (109) and a second microprocessor (110); and a first dedicated bus and a second dedicated bus. The microprocessor system has: a first state in which the first dedicated bus uses a first data layer format and the second dedicated bus uses a second data layer format; and a second state in which the first dedicated bus is switched to use a second data layer format; the second dedicated bus is switched to use the first data layer format; or the first dedicated bus is switched to use the second data layer format and the second dedicated bus is switched to use the first data layer format; the microprocessor system is arranged to switch from a first state to a second state upon determining that a fault is present on the bus.
提供一种对于线控转向的转向装置的控制。微处理器系统包括:方向盘促动器控制器,其包括第一微处理器(107)和第二微处理器(108);前桥促动器控制器,其包括第一微处理器(109)和第二微处理器(110);第一专用总线和第二专用总线。微处理器系统具有:第一状态,其中第一专用总线使用第一数据层格式并且第二专用总线使用第二数据层格式;以及第二状态,其中第一专用总线切换成使用第二数据层格式;第二专用总线切换成使用第一数据层格式;或者第一专用总线切换成使用第二数据层格式并且第二专用总线切换成使用第一数据层格式;微处理器系统被布置成在确定在总线上存在故障时从第一状态切换到第二状态。
