Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as figure 1 Shown is a working flow chart of a vehicle active safety system sensor data fusion method of the present invention, including:

[0020] Step S101, including: acquiring multiple sets of sensor track point information groups from different sensors, the sensor track point information sets include measurement parameter values ​​of multiple track point parameters, each set of sensor track point information groups refers to a target, and the The track point parameter is the movement variable of the indicated target;

[0021] Step S102, including: judging whether multiple sets of sensor track point information groups refer to the same target, and if they refer to the same target, then perform step S103;

[0022] Step S103, including: comprehensively calculating the measurement parameter value of each track point par...

Abstract

The invention discloses a method for fusing the sensor data of a vehicle active safety system. The method comprises the following steps: obtaining a plurality of sensor track point information groups respectively from different sensors; judging whether the plurality of sensor track point information groups refer to the same object, and if so, performing comprehensive calculation on the measured parameter value of each track point parameter in the plurality of sensor track point information groups referring to the same object to obtain the target parameter value of each track point parameter, and then generating a target track point information group containing a plurality of target parameter values. The method realizes the fusion of a plurality of sensor track point information groups; the advantages of different sensors are developed so that the values of the track parameters of the track point information groups can be more accurate. Meanwhile, due to mutual compensation of a plurality of sensors, sensors higher in performance are not required.

Description

technical field [0001] The invention relates to the technical field related to automobiles, in particular to a sensor data fusion method and system for an active safety system of a vehicle. Background technique [0002] Traditional vehicle safety function configurations, such as anti-lock brake system (ABS), electronic brake force distribution system (EBD), traction control system (TCS), airbag (SRS), etc., have been widely used in domestic and foreign car companies All levels of vehicle products, and gradually become the standard configuration of high-end brand cars. However, most of these functions are activated or intervened to ensure the safety of the vehicle body or passengers in the vehicle when the danger occurs or after it has occurred. Since the activation or intervention time of these safety functions is relatively late, the final loss caused by the accident is still relatively small. Large or cannot be completely avoided. In order to make up for the shortcomings...
