Based on Huahai Technology's RapidECU all-domain electronic control development platform, this solution addresses industry pain points of traditional intelligent driving systems — weak perception redundancy, large multi-sensor fusion deviation, lagging decision planning, poor vehicle-control smoothness, insufficient stability under high/low temperature conditions, disconnected coordination between intelligent driving and the vehicle chassis/powertrain, and difficult mass-production adaptation — delivering a professional, integrated intelligent driving domain control solution. As the core of vehicle intelligent driving decision-making, the solution coordinates all types of sensor data from cameras, radar, LiDAR and millimeter-wave radar, completing the full closed loop of environment perception, target recognition, path planning, vehicle decision-making and chassis execution control, achieving full-function coverage from assisted driving to high-level autonomous driving. Backed by a full proprietary toolchain — ECUCoder automatic code generation, MeCa measurement & calibration, SimCar intelligent-driving-dedicated HIL simulation and the SimCore virtual proving ground — it is fully compatible with MATLAB/Simulink model-based development, supports the AUTOSAR architecture, SOA service-oriented adaptation and the ISO 26262 functional safety system, and adapts to all powertrain types: battery-electric, hybrid, range-extender and fuel vehicles. It covers the full lifecycle of prototype algorithm validation, bench simulation testing, real-vehicle calibration adaptation and mass production, effectively improving the safety, comfort, scenario coverage and all-weather stability of intelligent driving.
