Environment – Automotive Equipment Group

Business Overview and Environmental Issues for Which Risks and Opportunities Have Been Recognized and Evaluated

Strengthening Our Global Development, Production, and Sales Systems

The Automotive Equipment Group provides powertrain products, body control products, and car multimedia devices globally. As a full support supplier, we work together with our customers to develop cutting-edge technologies and endeavor to provide a wide range of services, from production, sales, and supply to spare parts and rebuilds. To reduce environmental load, our three development sites in Japan (Himeji Works, Sanda Works, and Automotive Electronics Development Center) function as mother factories that manage our 14 production sites in 11 countries overseas to ensure compliance with environmental guideline designs that take into consideration environmental regulations, product environmental restrictions in each country and region, and the disposal and recyclability of products, as well as preventing air, water, and soil pollution.

Environmental Issues for Which Risks and Opportunities Have Been Recognized and Evaluated

  • Climate change
  • Proper management of chemical substances in design and manufacturing
  • Air, water and soil pollution during operations and procurement
  • Conservation of biodiversity in operating areas

Message from the Automotive Equipment Group

Contributing to the Realization of a Low-Carbon Society through the Development of Low Fuel Consumption Technology for Vehicles

Isao Iguchi
Senior Vice President
In Charge of Automotive Equipment

The Mitsubishi Electric Group is contributing to the realization of a sustainable global environment with the aim of being a global, leading green company.

The Automotive Equipment Group is developing its business at the global level. It is engaged in initiatives to reduce CO2 emissions both by installing its products in vehicles to achieve better fuel efficiency and by reducing energy consumption during the manufacturing process.

In regards to improving the fuel efficiency of automobiles, engines are becoming more efficient in order to achieve low fuel consumption. Mitsubishi Electric is helping to make vehicles more efficient through related products such as ignition systems for the precise control of combustion in high­compression ratio engines, turbo actuators that control the boost pressure of downsized turbo engines, and the control of these systems.

We are developing motorized equipment that is more compact and that has higher efficiency. Examples include a compact motor for electric power steering being applied in large vehicles, a belt-driven motor generator with an enhanced deceleration energy regenerative function, and quiet idling stop restarters.

As an example of energy saving during the manufacturing process, a new production building has introduced LED lighting and cutting-edge energy-saving technologies such as automatic light adjustment, and central monitoring and optimized control of air conditioning and ventilation equipment. We are managing the use of electricity by rigorously enforcing energy-saving measures such as photovoltaic generation in existing buildings. These achievements are being implemented at overseas manufacturing bases as part of our global energy-saving efforts.

Initiatives Contributing to the Environment and Society

Fuel Efficiency Technologies for Internal-Combustion Engines

Climate change

Motor generator

We are helping to make automobiles more fuel efficient through products that are compact, lightweight, and offer high performance and high efficiency, such as alternators, starters, and electric power steering systems. Our motor generator, ensures reduced fuel consumption for customers by integrating the start-stop functions of the engine control unit, transmission control unit and starter with the electricity-generating function of the alternator, enabling wide-ranging technologies such as engine assist during idle stop-and-start and energy regeneration during deceleration. In February 2015, our GXi alternator acquired Europe's ECO Innovation Technology certification.

Electric-Powered Products Contributing to the Popularization, Safety and Comfort of EVs/HEVs

Climate change

By optimizing Mitsubishi Electric's strengths such as semiconductor device design, circuit design, structural design and vehicle motion control technologies, we aim to provide more efficient electric-powered products* that integrate multiple technologies to achieve even better fuel economy and enhanced compliance with emissions regulations.

*
Electric-powered products: Products that contribute to promoting the use of electricity in vehicles by having equivalent or superior functions compared to devices driven by gasoline combustion.

Main electric-powered products


Car Navigation Systems Helping to Conserve Energy

Climate change

DIATONE SOUND.NAVI high-end audio and car navigation system

To make fuel efficiency more enjoyable for customers, we are developing and supplying car navigation systems that include a function to search for the route with the best energy savings to minimize fuel consumption, and a function to evaluate to what extent the driver is driving in an eco-friendly manner.

Promoting Proper Management of Chemical Substances in Design and Production

Proper management of chemical substances in design and manufacturing

The Automotive Equipment Group is actively expanding its business globally and is striving to ensure compliance with REACH regulations, the ELV directive of the EU, and other environmental laws and regulations around the world that cover its activities and products. Additionally, since the chemical substances management system of the International Material Data System (IMDS) has been introduced in the automotive industry, we ensure compliance with environmental guideline designs that consider the disposal and recyclability of automobiles.

Expanding the Rebuilding Business

Climate change

The Automotive Equipment Group is expanding our business to automotive electrical parts, such as alternators and starters. As opposed to selling disassembled parts as used parts (reuse) as is, rebuilt parts have been disassembled and functionality that has deteriorated over use is repaired and restored to its original function so that quality equivalent to a new part is achieved (recycle).

Initiatives for Reducing Environmental Impact

Roll out of Measures Implemented in Japan at Our International Sites

Climate change
Air, water and soil pollution during operations and procurement

The following measures have been promoted at Himeji Works, Sanda Works, and Automotive Electronics Development Center in Japan and are being introduced throughout the Americas, Europe, and Asia.

  • Lean manufacturing to avoid the 3 "M"s: muda, mura, muri (meaning "waste", "variation", and "overburden" in Japanese)
  • Updating to more efficient equipment
  • Improving operation using just-in-time activities
  • Introducing initiatives to prevent air, water, and soil pollution
  • Sharing of best practices
