Abstract: A method and apparatus that perform threat zone assessment in a host vehicle are provided. The method includes detecting a target vehicle in a nonadjacent lane with respect to the host vehicle, determining dimensions of the detected target vehicle, a type of the detected target vehicle, and geometry of a road on which the detected target vehicle and the host vehicle are traveling, calculating the threat zone based on the dimensions of the detected target vehicle, the type of the detected target vehicle, or the geometry of the road on which the detected target vehicle and the host vehicle are traveling, and controlling the host vehicle to avoid the calculated threat zone by accelerating the host vehicle, decelerating the host vehicle, or aborting a lane change by the host vehicle.

Abstract: A method to establish a lane-change maneuver, the method includes the steps of calculating a plurality of anchor points along a projected vehicle route and, based on the plurality of anchor points, generating a lane-change maneuver trajectory. The plurality of anchor points can include: a first anchor point based on time, a second anchor point where the vehicle would cross a lane boundary from a host lane to a target lane, and a third anchor point where counter steering torque would be applied to center the vehicle in the target lane.

Abstract: A powertrain optimization method is used to identify the optimal torque operating range. The method for controlling the vehicle includes: receiving, by a planning controller, a trip plan based on an input from a vehicle-operator, wherein the trip plan is indicative of a planned trip; determining, by the planning controller, a current location of the vehicle using a Global Navigation Satellite System (GNSS) of the vehicle; determining, by the planning controller, a geography of the planned trip using map data from a map database; determining, by the planning controller, a target speed profile for the vehicle as a function of the trip plan, the geography of the planned trip, and a predetermined, optimal acceleration range; determining, by an adaptive cruise controller, a torque request as a function of the target speed profile, a predetermined-optimal torque range, and a current speed of the vehicle.

Abstract: An automotive vehicle includes at least one actuator configured to control vehicle steering, shifting, acceleration, or braking, at least one sensor configured to provide signals indicative of a location and velocity of an object external to the vehicle relative to the vehicle, and at least one controller in communication with the at least one actuator and the at least one sensor. The at least one controller is configured to, in response to a signal from the at least one sensor indicating that a relative velocity between a rearward object and the vehicle exceeds a first threshold and a distance between the rearward object and the vehicle falls below a second threshold, automatically control the at least one actuator to maneuver the vehicle from a first lateral position with respect to a current driving lane to a second lateral position with respect to the current driving lane.

Abstract: A system according to the present disclosure includes a lane boundary module, a vehicle trajectory module, an intersection location module, a lane departure module, and a driver warning module. The lane boundary module is configured to determine a boundary of a lane within which a vehicle is travelling. The vehicle trajectory module is configured to predict a trajectory of the vehicle. The intersection location module is configured to determine M locations of M intersections between the vehicle trajectory and the lane boundary at M times, where M is an integer greater than one. The lane departure module is configured to identify a potential lane departure based on the M locations. The driver warning module is configured to activate a driver warning device to warn a driver when the potential lane departure is identified.

Abstract: A system including a current module, a second module, and a temperature module. The current module is configured to determine an amount of current drawn from a power source by a hydraulic pump of a transmission based on a current signal received from a current sensor. The current signal is indicative of the current drawn by the hydraulic pump. The second module is configured to determine (i) a speed of the hydraulic pump based on a speed signal received from a speed sensor, or (ii) an output torque of the hydraulic pump based on the amount of current drawn by the hydraulic pump. The speed signal is indicative of the speed of the hydraulic pump. The temperature module is configured to estimate a temperature of a hydraulic fluid circulated by the hydraulic pump based on (i) the amount of current drawn by the hydraulic pump, and (ii) the speed or the output torque of the hydraulic pump. The second module is configured to adjust the speed of the hydraulic pump based on the temperature of the hydraulic fluid.
