Quality
Evolving into a group that can contribute to society together with our customers through system proposals.
We develop mechanical parts such as switches that make up automobiles and motorcycles, hardware design, software design, and control logic construction for control units that control power steering and various vehicle bodies, as well as smart entry and digital key systems that combine these with wireless communication technology. In recent years, we have also been developing voltage converters and on-board chargers required for hybrid and electric vehicles.
In addition, our specialized teams support development by taking on regulatory management, development infrastructure development, production technology development, and parts purchasing for development, which are essential for our product development.
In the future, mobility will shift to electrification. Accordingly, the expectations for in-vehicle electrical components to further enhance the value of mobility are rising day by day. Our company will evolve from the development of single-function control units to a group that can contribute to society together with our customers by proposing systems that connect the many sensors and actuators installed in mobility vehicles in a complex manner and increase value with the power of software. In the development of existing products, we will provide high-quality, high-performance, low-cost products, systems, and services with a customer-oriented attitude.
We will also strengthen our collaboration with overseas development bases spread around the world and work to create new value by bringing together global knowledge.

Product introduction
We provide products centered on various controllers, switches, and sensors used in car body control, which are essential for car electronics, in order to contribute to solving social issues in a mobility society by evolving in-vehicle electronic control technology.
In recent years, while automobiles have spread around the world as a convenient means of transportation, problems caused by automobiles have also become larger. For example, in emerging countries, the increase in the number of deaths due to traffic accidents and respiratory diseases caused by automobile exhaust fumes is becoming a problem. To solve these social issues, we will focus on developing products necessary for connected, autonomous driving, and electrification in order to increase our contribution to safety, security, and the environment.
Electric Power Steering Control Unit(EPS)
EPS is a controller that uses a motor to assist the driver in steering the vehicle, reducing the burden on the driver.
Compared to conventional hydraulic power steering, electrification improves fuel efficiency by 3 to 5%. Of the basic functions of a car - running, turning, and stopping - this unit is involved in the "turning" function, and since a breakdown in this unit can easily lead to an accident, it is considered an important safety component.
Our company's highly reliable safety designs and manufacturing capabilities allow us to achieve the high quality befitting an important safety component.
In addition, no oil is disposed of, which contributes to reducing the environmental impact.

DC/DC Converter for Idling Stop System
This unit boosts battery voltage that drops below normal levels.
In vehicles equipped with an idle stop system, it boosts the battery voltage that drops when the engine is restarted, preventing electronic devices such as navigation systems from having to restart every time the vehicle is stopped.
By improving the convenience of the idle stop system, it contributes to improved fuel efficiency and reduced exhaust gas emissions in gasoline engine vehicles.

DC/DC converter for xEV
This product is necessary for vehicles equipped with high-voltage batteries such as EVs and hybrids. It is a unit that steps down the voltage of several hundred volts supplied from the high-voltage battery to 14V and supplies power to various on-board controllers.
Our unique technology has made it compact and highly efficient, contributing to vehicle weight reduction, securing passenger space, and improving power consumption.

On Board Charger(OBC)
This unit converts household alternating current (AC) into direct current (DC) to charge the high-voltage batteries of EVs and plug-in hybrid vehicles from a household outlet.
Our unique technology has made it compact and highly efficient, helping to reduce vehicle weight, free up interior space, and shorten charging times. We are currently working on development toward mass production.
Driveline Control Module(DLCM)
This controller switches between 2WD and 4WD, and controls the electronic limit, slip and differential gear (eLSD).
By controlling the vehicle's drive system according to the road condition, it can improve the vehicle's ability to climb hills and its ability to escape rough roads.
When driving in town or on paved roads or other easy roads, this control can be turned off to increase the efficiency of drive force transmission, contributing to improved fuel economy.
