Abstract: A collision avoidance method for an autonomous driving vehicle (ADV), the method comprising: A) obtaining a current vehicle state of the ADV and a planned trajectory of the ADV over a predetermined drive period, wherein the planned trajectory is generated according to an initial vehicle state of the ADV and an environment of the ADV when the ADV is at the initial vehicle state, and wherein the initial vehicle state is a vehicle state of the ADV when the ADV is at a start point of the predetermined drive period; B) generating a simulated trajectory over at least a portion of the predetermined drive period based on the current vehicle state and the planned trajectory; C) determining whether the simulated trajectory overlaps with an obstacle; and D) decelerating the ADV in response to a determination result that the simulated trajectory overlaps with an obstacle.

Abstract: A method for controlling a vehicle using a model predictive controller generating consecutive sets of reference states at a calculation frequency. In one embodiment, the method comprises: receiving a trajectory reference for guiding movement of the vehicle; generating, in a calculation cycle repeated at the calculation frequency, a set of reference states based on an initial state of the vehicle at a start time of the calculation cycle and the trajectory reference; sending the set of reference states to a second controller; detecting, by the second controller at a detection frequency equal to or higher than the calculation frequency, an updated state of the vehicle; generating a vehicle control parameter value based on the updated state of the vehicle and a reference state of the set of reference states; and controlling the vehicle using the vehicle control parameter value.
