Car side sliding door control solution based on Hangshun automotive grade MCU HK32AUTO39A

Compared with traditional doors, automobile sliding doors are easy to park, have a wide opening width, and are convenient for passengers and cargo to enter and exit. They are very popular among consumers. In the automobile market, both high-end business luxury MPVs and light buses for urban logistics and low-end passenger mini cars all use automobile mechanical sliding door systems.

The automobile electric sliding door system PSD (Power Slide Door) is an advanced sliding door system that integrates intelligent control and execution technology based on mechanical sliding doors. The main technical points are:

(1) Electric sliding door ECU control system.

(2) Independent power supply system to ensure continuous power supply to the sliding door without affecting the opening of the sliding door.

(3) Higher requirements for body accuracy to ensure the smooth opening and closing of the body sliding door system.

The electric sliding door of the commercial vehicle of mainstream car manufacturers adopts the electric sliding door control system developed based on the HK32AUTO39A automotive-grade MCU of Hangshun Chip. The control system has the functions of detecting the position status of the sliding door lock and the sliding door, anti-pinch injury and manual and automatic door opening.

This solution uses the internal advanced timer PWM output of the 32-bit microcontroller HK32AUTO39A to control the sliding door lock motor, with an XYZ three-axis acceleration sensing module, to detect the inclination of the vehicle body and adjust the sliding door lock motor speed, so as to achieve the effect of smooth opening and closing of the sliding door.

The electric sliding door control system developed based on Hangshun chip’s automotive-grade MCU HK32AUTO39A can operate stably in various harsh environments, and the system has high reliability and durability. This solution not only improves the intelligence level of the vehicle, but also provides passengers with a safer and more convenient riding experience.

Strong scalability: HK32AUTO39A uses the ARM® Cortex®-M3 core and has a good ecological environment; its rich peripheral resources can meet the expansion needs of the platform to the maximum extent. In addition, the HK32AUTO39A series products include LQFP64, LQFP48, QFN32 and QFN28 and other optional packages.

High reliability: HK32AUTO39A has passed the strict AEC-Q100Grade1 reliability and safety certification, and the product quality meets the zero-defect supply chain quality management standard ISO/IATF 16949 specification. This year, Hangshun chip passed the highest level certification of automotive functional safety ISO26262 ASIL-D. In addition, the product supports an ambient temperature of -40℃~125℃ and has a design life of 15 years.

Compared with automotive MCUs with the same performance/resources, HK32AUTO39A has a super high cost-effectiveness and a more complete ecological support.
