Latest Patents

Matsuyama's recent patents include groundbreaking technologies such as a work machine control system, work machine, and work machine control method. One notable innovation involves a distance calculation unit that determines the bucket distance, which measures the distance from a point on the bucket to a target design surface that represents the desired shape of the excavation target. The intervention control unit then calculates an intervention control amount to regulate the speed of the work equipment, ensuring that the bucket does not intrude on the target design surface. Additionally, an attachment control unit computes an attachment control amount to rotate the bucket around an attachment axis, keeping the edge of the bucket parallel to the target design surface. Furthermore, an attachment limiting unit restricts the rotation of the bucket to prevent any increase in the bucket distance due to the movement of the work equipment.

Another significant patent features a control method for work machines. This method includes calculating the maximum flow rate of hydraulic oil from a hydraulic pump, determining the first and second target speeds of the working equipment based on various operational dynamics, and outputting a control signal for hydraulic actuators based on these computations to enhance efficiency and precision in work operations.
