Path planning in mobile robots
The invention provides a computer-implemented method of planning a path for a mobile robot such as an autonomous vehicle in the presence of K obstacles. The method uses, for each of the K obstacles, a shape Bk and a density function pk(x) representing the probabilistic position of the obstacle. The method repeats the following steps for at least two different paths A: —choosing a path A, where A is the swept area of the robot within a given time interval; and—calculating based on the density function of each obstacle and the swept path an upper bound on the total probability of at least one collision F.sub.D between the robot and the K obstacles. This allows a number of candidate paths to be ranked for safety. By precomputing factors of the computational steps over K obstacles, the computation per path is O(N), and not O(NK). A safety threshold can be used to filter out paths below that threshold. An operating path to control the robot can be selected from the remaining paths, optionally based on other factors such as comfort or efficiency.
Systems and methods for collision avoidance
The disclosure is directed to systems and methods for operating or controlling an ADAS mechanism. A first sensor of an ADAS mechanism can determine a potential obstacle to a vehicle, and a position of the potential obstacle relative to the first sensor. A second sensor can determine a gaze angle of a user of the vehicle. An activation engine in communication with the first sensor and the second sensor can determine a proximity of the gaze angle of the user to the determined position of the potential obstacle. The activation engine can control, in response to the determined proximity, an operation of the ADAS mechanism for responding to the potential obstacle.
Vehicle traveling control apparatus
A vehicle traveling control apparatus for a vehicle identifies a mobile object as a crossing mobile object if the supplementary angle of the angle formed between the velocity vector of the mobile object and the traveling direction of the vehicle is greater than a threshold. In a case where the supplementary angle was equal to or less than the threshold before the identification as the crossing mobile object and where a lateral position of the crossing mobile object is equal to or less than a distance threshold at the time of the identification, or in a case where the size of the crossing mobile object has been less than a predetermined value for a predetermined period of time or longer and where the lateral position is equal to or less than the distance threshold at the time of the identification, the crossing mobile object is excluded from emergency braking targets.
