Cirrus Logic has launched its latest family of closed-loop haptic drivers CS40L51, CS40L52 and CS40L53, marking the company’s first haptic driver solutions reliability qualified in accordance with the AEC-Q100 automotive standard. The family of products brings Cirrus Logic’s proven expertise in consumer and smartphone haptics to the automotive space, enabling a more consistent, immersive and intuitive tactile user experience across a wide range of in-cabin interfaces.
As auto makers look to elevate and differentiate vehicles with personalized, immersive experiences, haptics-enabled smart surfaces play a critical role in enabling premium interior designs that are sleek, modern and sustainable. Cirrus Logic’s closed-loop technology improves actuator response, creates a wider range of haptics effects and delivers consistent performance across varying conditions. This ensures high-definition haptic feedback on interactive displays, steering wheels, smart surfaces, center consoles, smart seats and more.
“Consumers expect a high level of responsiveness from haptics experiences. Early adoption of haptics in vehicles was not intuitive or consistently reliable, and didn’t deliver a realistic tactile experience,” said Vlad Bulavsky, director, automotive solutions, Cirrus Logic. “Cirrus Logic’s new low latency, closed-loop haptics technology addresses this challenge for automotive designers who are redefining how we interact with our cars and take user experience to the next level.”
“As screens replace physical controls in vehicles, the industry has recognized the need for sophisticated tactile feedback to bridge the gap,” said Peter Cooney, chief technology analyst at DATAportl, a market research provider. “We are moving past basic vibration to advanced, high-definition haptics that simulate physical textures and clicks. This shift is essential for reducing distraction and is the primary force driving the automotive haptics market today.”
Cirrus Logic’s family offers features for various needs and budgets, simplifying design by integrating key components.
CS40L51 combines advanced sensor-less velocity control (SVC), real-time audio to haptics synchronization (A2H) and active vibration compensation (AVC) for immersive, high-fidelity feedback.
CS40L52 features the advanced closed-loop control SVC that optimizes the system’s haptic performance in real-time by reducing response time, increasing frequency bandwidth and compensating for manufacturing tolerances and temperature variation.
CS40L53 features the Click Compensation algorithm to enable consistent haptic feedback across systems by adjusting haptic effects based on the actuator manufacturing characteristics.
