摘要： In a power control device, when the necessary power is greater than an upper limit value and either the integral power value or the duration time of an assist provided by an electric storage device during a continuous assist by the electric storage device exceeds a predetermined first threshold value, a controller performs a first control of reducing an assist power by the electric storage device to a value smaller than an assist power for the regular control and greater than zero. Further, when the necessary power is greater than the upper limit value and either the integral power value or the duration time exceeds a predetermined second threshold value greater than the first threshold value, the controller performs a second control of setting the assist power to zero.

摘要： A memory stores, in advance, target line information indicating an arrangement target of an object to be conveyed and related to a target line denoted by at least one of a curve or a polyline. A controller is configured to: calculate, based on the target line information, target information which is at least one of information about a target coordinate of the object and information about a target direction of the object; calculate, based on the at least one of the coordinate of the object and the direction of the object detected by the detector, detection information which is comparable with the target information; calculate a deviation of the detection information from the target information; and cause a display to display a moving direction of the object which allows the deviation to decrease.
