AISIN’s Electrification and Intelligence: A Test Drive Experience [Part 2]
In August 2024, AISIN held a Technology and Test Drive Experience Event at the AISIN Toyokoro Proving Ground in Hokkaido, Japan. Following up on Part 1 of this series, automotive writer Motoki Watase takes us deeper into the innovative electrification and intelligence technologies showcased at the event.
As the automotive industry undergoes rapid change, AISIN, a key automotive parts manufacturer, is adapting its business strategy. A major focus is on electrification and intelligence, building on its established expertise in areas like transmissions. AISIN’s approach involves comprehensive parts development, focusing on improving overall vehicle efficiency.
Electric Disc Brakes for Enhanced Braking
Modern vehicles are increasingly employing “by-wire” technology to transmit commands more efficiently. This approach replaces mechanical linkages with electronic signals, leading to faster response times. ADVICS, an AISIN Group company, is integrating this technology into brakes through electric disc brakes.
The Future Brake system, slated for introduction in Step 1, is initially implemented in the rear wheels. This design choice offers several advantages. Specifically, the rear wheels have been modified to electric, which allows for improved packaging versatility and weight reduction. Furthermore, the control range of regenerative braking is expanded. The elimination of hydraulic oil contributes to a reduced environmental impact, too.
During the test drive, the electric brakes provided a natural feel, essentially indistinguishable from traditional hydraulic brakes. However, the response time was notably improved, aligning with ADVICS’s claim of a 7% reduction in braking distance.
Aerodynamic Devices for Better Maneuverability and Efficiency
AISIN has developed aerodynamic devices to enhance electricity efficiency. These components, tested during the event, are designed to reduce drag. The result of deploying these aerodynamic devices is an improved electricity efficiency of up to four percent.
At higher speeds, the front grille shutter closes. The movable spats in front of the tires, rear spoiler, and rear diffuser all deploy. Door handles retract into the vehicle body. Watase noted that the effect was most noticeable during cornering, contributing to a smoother driving experience at high speeds.
Intelligent Systems for Enhanced Safety and Efficiency
AISIN is developing intelligent systems that utilize big data to improve safety, fuel efficiency, and electricity consumption. These systems go beyond basic functions. They incorporate information from various vehicle components, including brakes, steering, navigation, and drive units. The company’s work focuses on integrated vehicle control that manages each device according to the situation.
For example, when approaching a sharp corner, the vehicle can automatically control and decelerate to enter the corner at the appropriate speed. On slopes, it is also possible to implement control according to the weight on each wheel. This helps less experienced drivers manage challenging road conditions.
Stress-Free Entry and Novel Door Systems
AISIN’s intelligent technology also extends to features that improve the passenger experience. The Stress-Free Entry System, demonstrated at the test drive, automatically opens and closes doors. The system uses advanced sensors to determine a person’s intent, ensuring operation is timely and safe.
In addition, AISIN is developing a front and rear linked door system. The test vehicle featured a design where both front and rear doors open and close using arms, without requiring the traditional B-pillar structure. This allows for greater design freedom and easier access, even in tight spaces.
Conclusion
AISIN’s advancements in electrification and intelligence technologies suggest that commercialized vehicles are on the horizon. As the automotive industry moves towards a carbon-neutral future, AISIN’s role as a leading parts manufacturer will become increasingly important.
