A method and device for amending a reference path associated with a vehicle are disclosed. The method includes: (i) acquiring road segment data and reference path data, the reference path data having a plurality of anchor points defining the reference path along the road segment, (ii) using the road segment data and the reference path data to determine a safe deviation interval for each one of the plurality of anchor points, a given safe deviation interval for a given anchor point being indicative of an acceptable deviation of the vehicle from the reference path; and (iii) using the safe deviation intervals to determine an amended path for the vehicle instead of the reference path, such that by following the amended path the vehicle falls within the constraints of the road segment.

Systems and methods for autonomous driving which calculates path trajectories by incorporating latencies of vehicle components and calculations so that when the vehicle is in an autonomous driving mode and using a trajectory to calculate a designated path, the latencies of each vehicle component can be taken into account to provide a more accurate vehicle path.

The present invention relates to hybrid self-driving ground vehicle (100) for autonomous navigation In one embodiment, the hybrid self-driving ground vehicle (100) comprises a mobility platform (102) configured to actuate movement of the vehicle, an odometry sensor system (104) configured to continuously estimate translational and rotational motion of the mobility platform, a visual sensing system (106) comprising plurality of two-dimensional camera configured to acquire image data of an environment, an obstacle detection system (108) configured to detect dynamic and static obstacles, one or more processors (110, 112) operatively coupled to the odometry sensor system, the visual sensing system, and the obstacle detection system, wherein the one or more processors configured to: select between an Automated Guided Vehicle (AGV) operational mode and an Autonomous Mobile Robot (AMR) operational mode, continuously localize the vehicle using the odometry sensor system, intermittently perform environment mapping at selected keyframes by processing image data from the two-dimensional cameras to generate and update a two-dimensional navigation-oriented representation of the environment and autonomously navigate the vehicle within the environment while maintaining positional accuracy through intermittent calibration.

The invention discloses a method, device and equipment for determining the transverse distance of a target vehicle and a medium, and belongs to the field of automatic driving, and the method comprises the steps: obtaining the target driving parameters of the target vehicle and obtaining the driving parameters of the vehicle when the target vehicle exists in front of a road on which the vehicle travels; performing risk assessment according to the target driving parameter and the self-driving parameter to obtain an assessment result; if the assessment result is that the collision risk exists, the transverse distance of the target vehicle is determined based on the target driving parameters and the driving parameters of the vehicle, and the transverse distance is the distance between the vehicle body edge of the target vehicle and the left and right channel sidelines of the road. According to the method, the transverse distance detection is triggered only when the two vehicles have the collision risk, frequent calculation of non-threat targets is avoided, calculation power resource occupation is reduced, the resource utilization rate is improved, response delay of the vehicle control end due to frequent data input can be avoided, unnecessary forced movement is reduced, and the driving smoothness is improved.
