とする四輪操舵車の車速制限装置。 A front wheel steering mechanism, a rear wheel steering mechanism, a mode switching mechanism that selectively and reversibly transmits the steering direction and amount of steering of the front wheel steering mechanism to the rear wheel steering mechanism, and a mode switching mechanism that prevents the vehicle speed from exceeding a set value during four-wheel steering. A vehicle speed limiting device for a four-wheel steering vehicle, comprising: a main vehicle speed sensor; a backup vehicle speed sensor; a comparison means for comparing the output of the backup vehicle speed sensor with two high and low vehicle speed values; means for comparing the output of the sensor with the outputs of these comparison means to determine whether the main vehicle speed sensor is abnormal; and the vehicle speed limiting means is controlled based on the output of the main vehicle speed sensor when normal, and based on the outputs of both comparison means when abnormal. 1. A vehicle speed limiting device for a four-wheel steering vehicle, comprising: control means for operating the vehicle.
