Powertrain Systems (Engine)In order to meet increasingly stringent environmental regulations around the world, there is a need to efficiently convert fuel into kinetic energy, and reduce emissions of gases such as CO2.We have developed engine technologies such as direct injection and valve timing control that greatly increase the efficiency of internal combustion engines. In addition, we use simulation and analysis technologies to continually refine our components, improve engine thermal efficiency, and produce clean engines with a reduced environmental burden.

Expectations are increasing for safe, comfortable, and highly efficient autonomous driving systems that can eliminate accidents, reduce driver workload, and resolve traffic congestion, thereby helping to achieve a smart mobility society. In order to realize a safe and secure autonomous driving system, we are developing a sensor fusion system that can detect the surrounding situation by integrating sensor data from sources such as stereo cameras and radars. Data from this system is used by our autonomous driving ECU to make instantaneous decisions on acceleration, deceleration, and lane-changing.

Powertrain Systems (Electric) Advanced Driver Assistance SystemsIn recent years, vehicle electrification has seen remarkable progress, due in part to environmental regulations on zero-emission vehicles. In addition to Hybrid Electric Vehicles (HEV), Plug-in Hybrid Electric Vehicles (PHEV), and Electric Vehicles (EV), Mild Hybrid Vehicle systems using 48 Volt electricity are starting to appear.Vehicle electrification systems will prove essential for meeting environmental regulations. In addition to the main electric powertrain components of electric motors and inverters, we are developing other technologies to maximize eco-friendliness and driving performance.

Chassis SystemsChassis products determine the basic functions of automobiles - moving, turning and stopping.By coordinating and harmonizing the chassis with various control technologies, we can count on improved safety and comfort.In order to aim for an even higher level of safety, the core elements of brakes, steering, and suspension have been electrified and subjected to electronic control. We created a system that completely integrates all aspects of vehicle motion. The aim of this system is to improve motion performance by responding in real-time to changes in the state of tires, road surface and the vehicle itself, as well as to achieve autonomous driving, which requires coordinated driving control.
