    Abstract: Systems and method are provided for controlling a vehicle. In one embodiment, method includes: receiving, via one or more sensing devices, sensor data relating to an environment associated with the vehicle; determining, by a processor, at least one of a type of an intersection, a type of a traffic control device, and a signal of the traffic control device associated with an upcoming intersection based on at least one of the sensor data and map data; defining, by the processor, a first zone and a second zone of the upcoming intersection based on the at least one of the type of the intersection, the type of the traffic control device, and the signal of the traffic control device associated with an upcoming intersection; determining, by the processor, a current zone of the vehicle based on the first zone and the second zone and a position of the vehicle; and selectively controlling, by the processor, lateral movement and longitudinal movement of the vehicle based on a control method that evaluates the current zone, operator instructions, and autonomous control instructions when controlling the vehicle.

    Abstract: A blind zone mitigation system of a host vehicle comprises i) at least one sensor that determines position information of a target vehicle with respect to the host vehicle, and ii) an active lane positioning module. The active lane positioning module receives the position information from the at least one sensor and determines a blind zone of the target vehicle. The active lane positioning module, in an active lane position mode, accelerates the host vehicle to move the host vehicle out of the blind zone of the target vehicle or decelerates the host vehicle to move the host vehicle out of the blind zone of the target vehicle.

    Abstract: Systems and method are provided for controlling a vehicle. A path planning method for a vehicle includes establishing a first path for a first vehicle, then receiving, at the first vehicle, sensor data associated with a behavior of one or more leading vehicles observed in the vicinity of the first vehicle. The method further includes establishing a modified path that diverges from the first path based on the sensor data, then classifying, with a processor, an obstacle observed by the first vehicle as it travels along the modified path.

    Abstract: A vehicle includes a body, an aerodynamic element, a movement mechanism, a plurality of sensors, and a controller. The body is located along a longitudinal axis and a lateral axis. The aerodynamic element intersects ambient airflow, which generates an aerodynamic force. The movement mechanism moves the aerodynamic element, relative to the body, along the longitudinal and lateral axes. The sensors collectively generate input signals corresponding to an operating condition of the vehicle. The controller determines a current position of the movement mechanism, corresponding to a current location of the aerodynamic element on the axes and determines a desired position of the movement mechanism, corresponding to a desired location of the aerodynamic element on the axes. The controller transmits a movement signal to the movement mechanism to change position from the current position to the desired position, such that the aerodynamic element moves from the current location to the desired location.
