Abstract: Disclosed herein are methods and systems for motion planning in an autonomous vehicle (AV) that separate path planning and velocity planning and may use reference lines in combination with motion planners to determine paths. The method may include reference lines to project planning data into a S-L coordinate system. A motion planner algorithm uses the reference lines and previous path planning history to generate a path in the S-L coordinate system. A velocity is determined for the path. An AV controller is updated with the path and the velocity. Motion planning computations use a dynamic vehicle look-up table to determine possible vehicle motions based on an initial state and control input.

Abstract: The present application provides a tire pressure positioning method and apparatus. The method includes: obtaining turning information used to indicate turning of a vehicle; obtaining a y-axis acceleration of a tire pressure sensor in a tire of the vehicle, where a y-axis is an axial direction parallel to a wheel bearing; and determining a position of the tire pressure sensor according to the turning information and the y-axis acceleration. Information about the y-axis acceleration of the tire pressure sensor is processed. Compared with a method in the prior art in which information about an x-axis acceleration and information about a z-axis acceleration need to be processed simultaneously, the method can reduce a data processing amount, thereby simplifying data collection and calculation processes and improving system operation efficiency.

Abstract: A system estimates the speed of a moving vehicle and hence the driving behavior of an individual driving the vehicle using accelerometer data. To do so, the system analyzes received accelerometer data to find idling points when the vehicle is not moving during a driving session. Based on the idling points, the system may divide the driving session into two or more segments. The system may then determine the speed of the vehicle at one or more boundary points of each segment. For each segment, the system may analyze the accelerometer data to determine the acceleration of the vehicle for points when the vehicle is moving. Subsequently, the system may calculate the speed of the vehicle for the points when the vehicle is moving based on the acceleration of the vehicle at the points when the vehicle is moving and the speed of the vehicle at the boundary points.
