Vehicle control system and method of use
A system for controlling a vehicle navigating a roadway, including a perception module that generates sensor data and outputs a cost map and traffic data associated with traffic objects, a behavior planning module that receives the cost map and the traffic data from the perception module and generates planner primitives, a training module that receives the cost map and the traffic data from the perception module, receives driver input from a vehicle operator, and trains the behavior planning module, a local planning module comprising a set of task blocks that receives the cost map from the perception module and the planner primitives from the behavior planning module, selects a task block, and generates control commands using the selected task block; and a control module comprising an actuation subsystem, wherein the control module receives the control commands from the local planning module and controls the actuation subsystem.
VEHICLE HANDLING SYSTEM AND METHOD
A method and system include a vehicle system including a plurality of vehicles. The system includes a handling unit comprising a communication device and a controller. The communication device receives first position data for a first vehicle of the vehicle system and second position data for a second vehicle of the vehicle system relative to a route on which the vehicle system is traveling. The controller determines that the first vehicle is entering into a curved portion of the route, and generates a control signal based on the first and second position data. The control signal changes an operating parameter of at least one of the first or second vehicles to control a separation distance between the vehicles or a deviation distance between respective travel paths taken by the first and second vehicles through the curved portion of the route.

Method and device for operating a vehicle
A method is for operating a vehicle which has actuators for influencing a driving behavior of the vehicle. The method includes sensing a setpoint for the driving behavior, in particular a steering angle set by a driver, and depending on the setpoint for the driving behavior, a first pilot control variable is determined using a model for the vehicle. Depending on the first pilot control variable, a second pilot control variable is determined using at least two partial models for the driving behavior of the vehicle, which differ due to the use of at least one of the actuators. Depending on the first pilot control variable and depending on the second pilot variable, a first setpoint for a first actuator is determined. The first setpoint is output in order to actuate the first actuator.
