Latest Patents
One of his latest patents is a control apparatus for electric vehicles. This invention aims to determine the timing of the electrical brake for complete stopping during electrical braking control. It achieves both reliable stopping and enhanced riding comfort by decreasing the braking force at a prescribed rate. The torque of the electric motor is managed through a power converter controller, which powers the motor. The deceleration of the motor is calculated based on the detected speed, allowing for precise control as the motor's rotational speed falls below a certain threshold.
Another significant patent is a program loading method and system for distributed processing systems. In this system, multiple processors are interconnected through a network, allowing for the transmission of programs among them. Each processor monitors the status of its programs and the load status of other processors. When a judgment operator is performed, the processor broadcasts a message indicating its status or program content to the network. This innovative approach ensures efficient program loading and execution based on the needs of each processor.
