KEPO 4D Exciter II: Seat Haptic Feedback for Smart Cockpit Interaction
KEPO 4D Exciter II is a seat-integrated haptic feedback system for smart cockpit and automotive seating applications. It uses vibration units built into the seat structure and software-defined haptic patterns to let occupants feel selected vehicle, entertainment, comfort, and safety-related information through the seat.
Analysis of the Three Lighting Methods for Automotive Ambient Lighting
Inside a car, you can often observe different qualities of light: some rays are sharp and clear, others soft and even, and some seem to emanate from within the vehicle itself. The reason behind this lies in the different lighting methods of ambient lighting—direct, indirect (reflective), and transmitted lighting.
Introducing the Upgraded KEPO 4D Exciter II
We are honored to introduce the all-new upgraded Kepo 4D Exciter II, delivering an entirely new dimension of immersive driving experience.
Interior Ambient Lighting Effects: Flowing vs. Breathing Light
In an interior ambient lighting project, dynamic effects are not just visual decoration. For project engineers, they need to be defined together with cabin scenarios, trigger signals, control logic, and lighting zones.
Two Work Stations on the Vehicle Exterior: Puddle Lamp and Logo Lamp in Series Production
Over the past decade, exterior lighting on production vehicles has expanded from a single function — nighttime visibility — into a set of distinct work stations. Two of them, the Puddle Lamp at the door-exit zone and the Logo Lamp on the body, have moved from luxury-segment differentiation toward mid-to-high-end electric platforms. KEPO has series-production programs in both product lines.
Beyond Vibration: How Haptic Seat Technology Is Redefining the Cabin Experience
That’s the premise behind KEPO 4D Exciter: a haptic actuator system that transforms the seat from a passive surface into an active interface between the vehicle and its occupants.
Kepo A2B Microphones and Speakers: Building High-Performance ANC and Full-Scenario Voice Communication for Smart Cockpits
In the wave of automotive intelligence, Active Noise Cancellation (ANC) and in-car voice communication have become key metrics for assessing cabin experience. For Tier 1 suppliers, how to achieve both high-performance noise cancellation and precise multi-zone voice interaction within the limited interior space is a significant challenge. Kepo’s A2B microphone and speaker series are built precisely for this purpose.
AVAS Warning Sound: Why Multiple Frequency Bands?
A single-frequency alert tone is vulnerable in real-world driving environments. It is easily masked by ambient noise, such as urban background sounds and conversations, while also failing to accommodate auditory variations across different age groups. To ensure the warning successfully reaches everyone nearby, a multi-frequency design is essential: Mid-to-low frequencies (400–800 Hz): Longer wavelengths enable […]
KEPO 4D Exciter: More than entertainment, it also protects safety
As cars become smarter, the cabin is no longer just a driving space—it’s an important area for interaction between people and cars, combining both safety and entertainment. The KEPO 4D Exciter deeply integrates seat vibration with systems like DMS (Driver Monitoring System), ADAS (Advanced Driver Assistance System), and cabin entertainment. It helps build a smarter […]
Why Are Physical Buttons in Cars Irreplaceable?
Euro NCAP will introduce a new assessment for the human-machine interface (HMI) in its vehicle safety evaluation system effective from 2026. This assessment will evaluate the placement, clarity, and ease of use of essential controls—including the availability of physical buttons for commonly used functions. Consumer feedback suggests that such buttons can help reduce driver distraction. […]
