The mini zone controller for automotive facet mirrors presents options like folding/unfolding, inclination adjustment, dimming, and defrosting with enhanced security and personalization choices.
Aspect mirrors, often known as wing mirrors or door mirrors, are an indispensable element of any car, serving an important function in making certain the motive force’s visibility and security. These mirrors present a transparent view of the areas to the facet and rear of the car which can be in any other case obscured from the motive force’s direct line of sight or the rearview mirror. By increasing the motive force’s field of regard, facet mirrors considerably scale back blind spots, permitting for safer lane adjustments, turns, and reversing manoeuvres. Moreover, their significance is underscored by authorized necessities in lots of areas, mandating their presence on all roadworthy automobiles.
The SL-MCAMC01004V1 facet mirror resolution by STMicroelectronics presents a cheap mini zone controller tailor-made for automotive facet mirror purposes. This controller leverages an SPC58 2B general-purpose automotive 32-bit Energy Structure MCU and an L99DZ200G multi-output driver to handle quite a lot of features, together with folding/unfolding, adjusting the mirror’s x/y-axis inclination, electrochromic dimming, and defrosting.
The driving force incorporates a present monitor to detect mechanical finish cease limits precisely and may energy two LED strings for flip indicators or puddle lights. Furthermore, the mixing of exterior encoders permits the monitoring of the exact place of the facet mirrors, facilitating the transmission of knowledge to the MCU for the implementation of security options and the creation of personalised positioning profiles for particular person car customers.
An non-obligatory function of the mini zone controller is its skill to be managed by way of CAN messages from a number ECU, thereby enhancing its connectivity and management capabilities.
At the side of the AutoDevKit growth initiative, which goals to help automotive engineers in managing the rising complexity of automotive electronics, our facet mirror analysis resolution presents a low-cost, complete equipment that permits designers to check numerous features of automotive mirror purposes effortlessly.
The AEK-MOT-MR200G1 facet mirror controller board, outfitted with the identical SPC58 2B MCU and L99DZ200G driver, features independently without having a website controller. The driving force permits the board to regulate folding/unfolding, x/y-axis inclination, electrochromic dimming, and defrosting features of a automotive mirror, along with powering two LED strings for flip indicators or puddle lights.
Moreover, the motive force integrates a present monitor (high-side solely) to detect the mirror’s mechanical end-stop limits. The board helps exterior encoders by way of devoted connectors, which decide the exact place of the facet mirror and relay this information to the MCU to implement security options or create and retailer personalised profiles for every car consumer.
