A system and method for performing autonomous emergency braking (AEB) is disclosed. The AEB system includes a front lateral detection sensor, a vehicle dynamics sensor, and an electronic control unit(ECU). The front lateral detection sensor detects a distance and a relative speed between a host vehicle and a peripheral object, or transmits peripheral images of the host vehicle to the ECU. The vehicle dynamics sensor detects a driving speed of the host vehicle, and transmits the detected driving speed to the ECU. The ECU receives detection signals from the front lateral detection sensor and the vehicle dynamics sensor, and increases a size of an AEB control available region and an AEB control available speed when at least one leading moving object or at least one external object is presentin longitudinal and latitudinal directions of a forward region of the host vehicle and the host vehicle is unable to perform steering avoidance capable of preventing collision with the leading movingobject or the external object. Accordingly, even when several leading vehicles are present not only in longitudinal and latitudinal directions of a forward region of the host vehicle and the host vehicle is unable to perform steering avoidance, the possibility of collision between the host vehicle and the leading vehicles can be reduced.

The invention relates to a six-axis robot fruit and vegetable picking path planning method based on an RRT* algorithm. The six-axis robot fruit and vegetable picking path planning method based on the RRT* algorithm reduces the path planning time and improves the working efficiency through adjusting the range of a search radius; the six-axis movement angle of the six-axis robot is limited to prevent a mechanical arm of the six-axis robot from moving to a singular point and a self-collision point, and the collision risk degree of the six-axis robot is reduced; the grabbing angle and range within the distance range of reaching the set termination point E are optimized; and a broken line inflection point of an updated tree is smoothed, so that the phenomenon that the six-axis robot shakes when moving to the broken line inflection point is avoided, and the real-time operability is improved. According to the invention, the path is planned by comprehensively considering the complexity of an agricultural scene, the shortest path, the maneuverability, safety, feasibility of the six-axis robot and other factors; and the six-axis robot fruit and vegetable picking path planning method based on the RRT* algorithm has good practicability.

The invention relates to an apparatus and method avoiding collision with obstacles in automatic parking assistance system. According to the invention, a plurality of sensors are arranged in the front part, the rear part, and the side parts of a vehicle, so that the moving detection area of the obstacles is enlarged, an obstacle area in the prior art which detects the obstacles in all of the images and only detects the images having brightness changes is replaced, the movement of the obstacles is detected by means of a main component analyzing method and an obstacle image characteristic valve, and a support vector machine is employed to indicate the decision boundaries by means of some of support vectors. According to the support vector machine, the detection performance is improved because the movement of the obstacles is detected by the main component analyzing method and the obstacle image characteristic value; the obstacle detection and the movement can be automatically detected without the need for drivers' operation, thereby being convenient; and the minimal change of a device in prior art can be realized by adding the functions of obstacle movement detection and collision avoidance.
