Abundant IO resources
Integrated digital signal detection, analog signal detection, high voltage interlock signal detection, high and low side drive, Efuse power distribution output.
Continuous warranty with robust hardware support:
The main chip has a main frequency of 300MHz, and is equipped with multi-core resources and large-capacity 10M flash, and comes with a hardware information security module HSM.
The ASIL D rated PMIC provides a strong guarantee for the power output of the whole machine.
Multi-channel sensor 5V power supply resources, single channel maximum power supply capacity can reach 200mA.
Efuse power distribution supports a one-to-many topology scheme to effectively reduce static power consumption.
Multi-channel CAN and LIN are flexibly matched.
Support ETH, radar interface.
Hard verification, the first combination of innovative technologies:
The first regional architecture solution, more centralized and efficient functional topology network, rich IO resources, support a variety of communication methods.
For the first time, the EPB electronic handbrake function is integrated into the zone controller, and the left and right areas each control a caliper, and the functional safety level reaches ASIL D.
For the first time, the ripple anti-pinch technology is applied to frameless doors, which puts forward higher requirements for the accuracy of ripple counting than traditional framed doors, and requires stronger robustness of the ripple anti-pinch algorithm.
The first electronic fuse Efuse intelligent power distribution solution supports the controller's low-power load power output, load protection and fuse self-recovery. Design software protection curve based on load characteristics to form safer and more efficient power supply network management.
The new diagnostic architecture solution supports multiple IO diagnostics and provides a complete controller diagnosis mechanism.
For the first time, the A/B dual grid redundant circuit design can realize power backup and support the limp home function to meet a variety of driving safety scenarios.
The complete sleep-wake mechanism and network management function can realize the restoration of sleep scenes, prevent false wake-up on the switch, etc., and effectively improve the robustness of sleep-wake up.
For the first time, a new four-layer software architecture was applied, accompanied by a new internal Smart Development Digital Platform (GSDP) system launched to comprehensively improve the efficiency of cross-domain software development.
On top of the standard, the new architecture unlocks stable and excellent operation of the system for OEMs
Reasonable function distribution integration helps OEMs greatly reduce the cost of wiring harnesses, improve vehicle integration, reduce vehicle quality, and improve the endurance of electric vehicles.
From traditional centralized power supply to regional power distribution, electronic fuses replace traditional mechanical fuses and diagnose load overcurrent and short circuit through software protection policies, providing a safer and more efficient power supply network.
Strong functional safety and information security design provides a strong guarantee for the stable operation of the entire system.
The regional distributed architecture effectively decouples software and hardware and provides a functional topology that is easier to upgrade.
With the improvement of the degree of automotive electronics, the electronic and electrical architecture of the whole vehicle is moving from distributed to centralized, intelligent and electrified. The explosive growth of automotive electronic software has made the functional topology of the whole vehicle more complex. Under the background of multi-sensor, multi-actuator, and multi-control unit participation in vehicle control, the vehicle function link is lengthy and scattered, which cannot effectively improve the integration of the whole vehicle, so cross-domain integration has become the recognized future of automotive electronic and electrical architecture.
The birth of the joint electronic area controller can greatly reduce the number of vehicle controllers, reduce the cost of vehicle research and development from multiple dimensions, break the traditional power supply network layout, and promote the development of electronic and electrical architecture in a more intelligent and electrified direction. In the future, United Electronics will meet customer needs with better products and help the new era of intelligent mobility.
