    摘要： An imitation learning-based machine-learned (ML) model to augment or replace the prediction and/or planner components of an autonomous vehicle may be trained using a two stage and multi-discipline approach. A first stage of training may include training the ML component to output a predicted action associated with a target vehicle and modifying the ML component to reduce a difference between the predicted action and the observed action taken by the target vehicle. A second stage may use reinforcement learning to further tun the ML component. The resultant model may be used on its own, with enough training data, or to rank or weight candidate trajectories generated by a planning component of the vehicle. The ML component may provide embeddings of environment features to first transformer(s) that output to a long short-term memory that outputs to second transformer(s) to determine the predicted action.

    摘要： A method for controlling a vehicle, the method comprising obtaining route data representing information about a portion of a route to be travelled by the subject vehicle and determining an efficient speed of the subject vehicle at a position along the route portion, in dependence on the route data, on a cost of operating the subject vehicle along the route portion, and on a progress of the subject vehicle along the route portion, comprising determining, independently of the step of determining an efficient speed, a maximum safe speed at the position along the route portion, in dependence on the route data, with an aim to avoid an accident involving the subject vehicle, wherein the maximum safe speed forms an upper limit of the subject vehicle speed at the position.

    摘要： A method for determining a speed profile of a motor vehicle on a route between a starting point and an arrival point. The method includes the steps of defining a series of noteworthy points of the route, which are characterized by a stoppage of the vehicle or a decrease in the speed of the vehicle, the series of noteworthy points dividing the route into a series of portions, for each portion of the route, generating a speed and/or torque setpoint optimizing the speed profile of the vehicle by minimizing the Hamiltonian of a system of equations modeling the driving of the vehicle, and providing the setpoint generated on each portion of the route so as to optimize the driving of the vehicle up to the arrival point.
