The invention discloses an intelligent automobile longitudinal driving assistance system based on driving characteristics. The intelligent automobile longitudinal driving assistance system comprises a driver state and environment sensing module, a driver characteristic real-time identification module, an intelligent decision-making and mode switching module and a style self-adaption longitudinal control module. The driver state and environment perception module analyzes environment information and driving behavior characteristics by constructing an extended intelligent driver model, and defines acceleration deviation to perform driving style clustering. And the driver feature real-time identification module deploys the BP neural network model in an online system to realize real-time identification of the driving style. The intelligent decision-making and mode switching module intelligently assesses risks in combination with driving styles and environment information, and dynamically switches four modes of cruise control, car following, early warning and emergency braking. And the style self-adaptive longitudinal control module adaptively adjusts a control strategy according to the driving style and the expected acceleration, and converts the expected acceleration into driving torque or braking pressure through a dynamic weight mechanism, so that personalized longitudinal control is realized.

    本发明公开了一种基于驾驶特性的智能汽车纵向驾驶辅助系统,包括驾驶员状态与环境感知模块、驾驶员特征实时辨识模块、智能决策与模式切换模块以及风格自适应纵向控制模块。驾驶员状态与环境感知模块通过构建扩展智能驾驶员模型,分析环境信息与驾驶行为特征,定义加速度偏差进行驾驶风格聚类。驾驶员特征实时辨识模块将BP神经网络模型部署于在线系统实现驾驶风格实时识别。智能决策与模式切换模块结合驾驶风格和环境信息智能评估风险,动态切换定速巡航、跟车、预警及紧急制动四种模式。风格自适应纵向控制模块根据驾驶风格和期望加速度自适应调整控制策略,通过动态权重机制将期望加速度转化为驱动转矩或制动压力,实现个性化纵向控制。
