摘要： An electric machine system includes an electric machine, an electric power converter, and a control unit. The electric machine includes a stator that includes coils, and a rotator that includes a magnet and is rotatable with respect to the stator. The electric power converter inputs electric power with respect to the coils of the electric machine. The control unit controls the electric power converter. The control unit includes an output unit and a correction unit. The output unit outputs a control signal for operating the electric power converter to the electric power converter. The correction unit corrects a phase of the control signal that determines input timing of the electric power with respect to the coils of the electric machine. The correction unit corrects the phase so that the magnitude of the electric power approaches an extreme value.

摘要： A system includes: a laser radar irradiating a detection region and detecting a reflected signal of the laser by a moving body in the detection region at a predetermined cycle, a vehicle detecting unit detecting a vehicle existing in the detection region based on the reflected signal detected by the laser radar, a vehicle tracking unit setting a plurality of divided regions in the detection region and detecting a moving direction of the vehicle based on a presence or absence of the vehicle in each of the divided regions detected by the vehicle detecting unit at each predetermined cycle, and a traffic flow calculating unit calculating a traffic flow data including a number of vehicles in each of the divided regions detected by the vehicle detecting unit and the moving direction of each vehicle detected by the vehicle tracking unit.
