Heating Ventilation, and Air Conditioning (HVAC)

Overview

Heating, Ventilation and Air Conditioning (HVAC) systems aim to regulate, heat, cool, ventilate, clean or dehumidify the indoor air quality (IAQ) within the vehicle cabin. HVAC systems consist of sensors and mechanical/electronic switches in the frontend and blower motors, actuators (for fresh air circulation control, air-flow control, and temperature control), and refrigeration units to transfer air to the cabin within the backend to ensure thermal comfort for drivers and passengers.

NXP provides a broad family of Arm^® Cortex^® -M-based MCUs (S32K) with motor control libraries to cover a wide range of needs in this application space. Additionally, NXP offers motor control-integrated solutions for a cost-effective, small footprint system solution for most HVAC applications. The broad portfolio of S12 MagniV^® devices combines MCU with SBC functionalities, network connection and motor control specific drivers in a single package and are supported by a library of motor control algorithms.
