Abstract: Provided is a diagnosis device that can determine the status of an anomaly besides the presence of an anomaly of a driven member. The diagnosis device is configured to diagnose a driven member having a rotary shaft, the driven member is rotated by driving of an externally mounted motor, and the diagnosis device calculates an estimated torque resistance of a combination of the driven member and the motor based on actual operation data obtained by driving the driven member by using the motor and finds a driven member and motor three-dimensional table that is a three-dimensional table of angles, angular velocities, and estimated torque resistances, finds a reference-state three-dimensional table that is a three-dimensional table of angles, angular velocities, and estimated torque resistances in a reference state, and calculates a determination three-dimensional table from a difference between the driven member and motor three-dimensional table and the reference-state three-dimensional table.

Abstract: A travel control device includes: a risk level calculation unit configured to acquire a speed in a traveling direction of a vehicle, a speed of the vehicle in a horizontal direction perpendicular to the traveling direction, and an azimuth angular velocity of the vehicle and calculate a rollover risk level based on a lateral load transfer ratio (LTR) of the vehicle; a deceleration calculation unit configured to calculate deceleration indicating an extent to which to lower the speed in the traveling direction when an absolute value of the rollover risk level exceeds a threshold value; and a control unit configured to control a driving system of the vehicle using a value obtained by lowering a target speed of the vehicle on the basis of the deceleration as a new target speed.
