A four-wheel vehicle comprising: a main controller configured with a microcomputer that calculates a rear wheel steering angle amount; and a rear wheel steering angle control circuit that sends an output of the main controller to a rear wheel steering actuator to provide a rear wheel steering angle amount. The steering control device includes a detection means for detecting a failure of the sensor, and when the detection means detects a failure of the sensor, captures and holds the rear wheel steering angle amount output from the main controller immediately before the failure occurs. a sensor compensation means for outputting a value for a certain period of time; a monitoring means for monitoring a failure of the main controller; and when a failure of the main controller is detected by the monitoring means, a rear wheel steering angle proportional to a steering state of the front wheels for a certain period of time; A four-wheel steering control device comprising: main controller compensation means for calculating and outputting an amount.
