The invention provides a driving assistance control method based on a vehicle-mounted millimeter wave radar. An environment sensing layer, a signal processing layer, a control decision-making layer and a response execution layer are included. The environment sensing layer is a 77G vehicle-mounted millimeter wave radar and is used for sensing external environment information; the signal processing layer identifies and selects the information and outputs effective information in the current scene; the control decision-making layer outputs required acceleration, braking and steering signals according to the target object information, the state of the vehicle and the like; and the response execution layer acts on the signal of the control decision-making layer and feeds back an execution result to the control decision-making layer. According to the technical scheme, the information of the main target closest to the vehicle can be obtained, the information of the auxiliary target shielded by the main target can be sensed, the signal processing layer fuses the information of the nearest vehicle and the information of the shielded vehicle and then makes a decision, the control method can improve the comprehensive response capability of the driving auxiliary system to the external environment, and the driving auxiliary system is more intelligent. Accurate decisions are made in advance, and driving safety is improved.
本发明提供一种基于车载毫米波雷达的驾驶辅助控制方法,包括环境感知层、信号处理层、控制决策层、响应执行层;所述环境感知层是77G车载毫米波雷达,用来感知外界环境信息;信号处理层对信息进行识别与选择,输出当前场景下有效信息;控制决策层根据目标物信息、车辆的状态等输出需求的加速、制动、转向信号;所述响应执行层对控制决策层的信号进行动作,并将执行结果反馈给控制决策层。上述技术方案不仅能够获取离本车最近的主目标信息,还能感知被主目标遮挡的辅助目标信息,信号处理层将最近车辆和被遮挡车辆的信息进行融合后,再进行决策,此种控制方法能够提高驾驶辅助系统对外界环境的综合响应能力,提前做出准确决策,提高行车安全。
