Title: Shigeaki Nakagawa: Innovator in Autonomous Lawn Care Technology

Introduction

Shigeaki Nakagawa is a prominent inventor based in Hyogo, Japan. He has made significant contributions to the field of autonomous lawn care technology, holding a total of five patents. His innovative designs focus on enhancing the efficiency and functionality of lawn mowers.

Latest Patents

One of Nakagawa's latest patents is a lawn mower with an autonomous traveling function. This advanced lawn mower includes a traveling driver, a mower motor, and at least one controller. The controller is designed to manage the traveling driver based on user operations and enables the mower to travel autonomously by utilizing information detected on the device. Additionally, the mower is equipped with a lawn detection device that assesses the condition of the lawn in its path and a position acquisition device that gathers self-position information. This technology allows the mower to prioritize areas that require mowing.

Another notable patent is a motor control system and control system for electric motor-driven vehicles. This system comprises a drive motor and a deck motor connected to a battery, an ECU, and a key switch. The key switch detects when the operation unit is activated and sends a restart permission signal to the ECU. When the state of charge (SOC) of the battery drops below a predetermined threshold, the ECU disables all motors. Upon receiving the restart permission signal, the ECU initiates a decelerated traveling mode, allowing the drive motor to resume operation at a reduced speed.
