A target tracking method and device, relating to the field of vehicles. The method comprises: reading a target fusion list at the current moment, wherein the target fusion list comprises a target attribute set corresponding to each environment target in one or more environment targets, and the target attribute set comprises parameter attribute sets, measured by one or more sensors, of the environment targets; determining whether the target fusion list at the current moment is an initial target fusion list or not; and if the target fusion list at the current moment is not the initial target fusion list, determining a target tracking list at the current moment according to the target fusion list at the current moment and a stored target tracking list at the previous moment, wherein the target tracking list comprises a parameter attribute set corresponding to each screened environment target and a fusion tracking ID.

Target tracking method and device

Disclosed are a road feature point extraction method and system. The road feature point extraction method comprises: acquiring map information for the current position of a vehicle, wherein the map information comprises the attributes of the current road and the attributes of the next road section; comparing the attributes of the current road with the attributes of the next road section to determine the road type of the next road section; and extracting, in conjunction with the road type of the next road section and the map information corresponding to the next road section, a road feature point representing a road scene on the next road section, and outputting the name of the extracted road feature point and information of the relative distance between the road feature point and the vehicle.

Road feature point extraction method and system

A method and a system for constructing a driving coordinate system for use in the field of smart transport. The method for constructing a driving coordinate system comprises: determining the road boundary line on one side of the road on which a current vehicle is situated as a reference line for constructing a driving coordinate system; in a vehicle coordinate system, determining the reference line point having the smallest distance between the reference line and the current vehicle position as an origin point OF of the driving coordinate system; on the basis of the origin point OF, determining the road guiding line direction as the XF axis of the driving coordinate system and determining the direction relative to the road guiding line direction according to the left-hand rule as the YF axis of the driving coordinate system; and, on the basis of the origin point OF, the XF axis, and the YF axis, forming a corresponding driving coordinate system.

Method for constructing driving coordinate system, and application thereof

A method for controlling lane changing of a vehicle, including: receiving a lane changing instruction (step); acquiring a speed parameter of the vehicle (step); according to the speed parameter, determining a controlling coefficient of a predetermined controller (step); acquiring a position-deviation parameter and a heading-angle parameter of the vehicle; if the position-deviation parameter is greater than or equal to a first threshold, or, if the heading-angle parameter is greater than or equal to a second threshold, according to the controlling coefficient, the position-deviation parameter and the heading-angle parameter, determining a target steering-wheel steering angle of the vehicle; and according to the target steering-wheel steering angle, controlling the vehicle to perform a lane changing operation, till the position-deviation parameter is less than the first threshold, and the heading-angle parameter is less than the second threshold (step). The cost of the vehicle lane changing is greatly reduced.

Vehicle lane change control method and device

A method for controlling vehicle travelling includes: detecting a plurality of travelling states of a vehicle, the plurality of travelling states includes a plurality of travelling directions; respectively previewing the vehicle travelling along the plurality of travelling directions from an original position in a lane to obtain a plurality of previewing paths; fitting a plurality of turning paths of the vehicle travelling from the original position to a target path in the lane according to the plurality of previewing paths; using the plurality of turning paths to calculate change information of a plurality of steering wheel angles; and adjusting the plurality of travelling directions according to the change information of the steering wheel angles, so as to control the vehicle to travel from the original position to the target path along the turning path.
