The Automotive Camera-Monitor System (CMS) is a cutting-edge visual technology that improves driver safety by offering enhanced visibility of the vehicle’s surroundings. Through advanced cameras, monitors, and processing systems, the CMS captures high-definition images, processes them via a sophisticated image processor, and displays the results on interior screens. This seamless integration significantly increases driver awareness, minimizing blind spots and improving overall driving safety.

Unlike traditional mirrors, the CMS provides broader, clearer viewing angles, a more compact design, and exceptional performance in various weather conditions. As intelligent driving technologies evolve, CMS is being integrated with Advanced Driver Assistance Systems (ADAS) to further elevate safety and functionality.

G32A1445 Automotive CMS Solution

Geehy’s automotive CMS solution, powered by the G32A1445 MCU, is designed to meet the increasing demands of the automotive sector. This advanced system utilizes wide-angle cameras to capture high-quality rearview and side images, reduce blind spots, and dynamically adjust rearview angles based on driving conditions, such as steering, reversing, or high-speed scenarios. The result is enhanced driver visibility and safety. The solution incorporates a high-definition LCD screen, delivering superior image clarity compared to traditional mirrors. It also offers intelligent features, including automatic mode switching, lens adjustments, and night vision capabilities, further improving the driving experience.

At the core of this system is the automotive-grade G32A1445 MCU, ensuring reliable and stable performance. It manages critical functions such as fault detection, vehicle communication, image display control, and angle adjustments, contributing to both driver comfort and safety. The MCU also features embedded analog EEPROM, enabling the storage of CMS state data for consistent and dependable operation.

The G32A1445 MCU controls the startup and current output of the FPGA circuit and interfaces with the BCM and other ECUs via the CAN bus. It communicates with the GMSL through UART/I2C interfaces, receiving and processing control commands from the BCM. The MCU monitors the power state via the ADC, ensuring proper operation of the electronic rearview mirror system. The system operates on a 5V supply for the microcontroller and 24V power from the vehicle interface. The SPI interface regulates voltage and current to maintain stable power delivery to all modules.
