A shift range control device (40) switches a shift range by controlling the drive of a motor (10), and is provided with an abnormality monitoring unit (55), and a torque suppression command unit (56).The abnormality monitoring unit (55) detects an occurrence of an intermediate range stop abnormality in which an output shaft (15) to which the drive of the motor (10) is transmitted stops in an intermediate range region outside a range guaranteed region in which the function of each range is guaranteed. The torque suppression command unit (56) issues a command to suppress torque acting on an automatic transmission (5) when an intermediate range stop abnormality has occurred.
换挡挡位控制装置(40),通过对电机(10)的驱动进行控制而切换换挡挡位,具备异常监视部(55)和转矩抑制指令部(56)。异常监视部(55)检测被传递电机(10)的驱动的输出轴(15)在保证各挡位的功能的挡位保证区域外即中间挡位区域中停止的中间挡位停止异常的发生。转矩抑制指令部(56)在发生了中间挡位停止异常的情况下,指令抑制作用于自动变速器(5)的转矩。
