Abstract: A drive control device is applicable to a vehicle including a first motor which drives a first wheel and a second motor which drives a second wheel. The drive control device includes a sensor, a torque setting section, an anomaly detection section, and an information output section. The sensor detects information about the drive control device. The torque setting section sets upper limit values of torques that can be generated by the first motor and the second motor based on the information detected by the sensor. The anomaly detection section detects an anomaly in the drive control device. In response to the anomaly detection section detecting the anomaly, the information output section outputs, to the torque setting section, setting information that sets the upper limit values of the torques of the first motor and the second motor to a common predetermined value, as the information.
