An energy calculation unit calculates an energy amount for each of a plurality of sides of a support polygon of a work machine in which the energy amount is required to cause the work machine to fall when the side serves as a rotation axis. An evaluation unit evaluates a possibility of the work machine falling based on the calculated energy amount for each of the sides.

Fall evaluation system, fall evaluation method, and work machine

A system searches for a track for a vehicle to travel automatically. The system includes a processor. The processor includes a route search unit, a restriction condition generation unit, and a track search unit. The route search unit searches for a series having elements of a position and posture of the vehicle, which is a route for moving from an initial position to a target position of the vehicle, based on a first restriction condition representing a position of an obstacle. The restriction condition generation unit generates a second restriction condition in which a penalty value increases according to a deviation distance from the route. The track search unit searches for a series having elements of a position, posture, speed, and steering angle of the vehicle, which is a track for moving from the initial position to the target position of the vehicle, based on the second restriction condition.
