Abstract: In a vehicle, an optimal path curvature limited by one or more constraints may be determined. The constraints may be related to lateral jerk and one or more vehicle dynamics constraints. Based on the optimal path curvature, an optimal vehicle path around an object may be determined. The optimal vehicle path may be output to a collision avoidance control system. The collision avoidance control system may cause the vehicle to take a certain path.

Abstract: A system and method for generating an overlay torque command for an electric motor in an EPS system for use in a collision avoidance system. The method uses model predictive control that employs a six-dimensional vehicle motion model including a combination of a one-track linear bicycle model and a one-degree of freedom steering column model to model the vehicle steering. The method determines a steering control goal that defines a path tracking error between the current vehicle path and the desired vehicle path through a cost function that includes an optimal total steering torque command. The MPC determines the optimal total steering torque command to minimize the path error, and then uses driver input torque, EPS assist torque and the total column torque command to determine the torque overlay command.

Abstract: A vehicle control system defines a set of predetermined criteria relating to the motion of the vehicle and a set of vehicle actions associated with the set of predetermined criteria. The vehicle actions each specify a steering action and/or a braking action. Friction data indicative of a frictional attribute (for example, coefficient of friction) of the contact region between the vehicle and the surface is received. The predetermined criteria are modified based on the friction data. When one or more of the predetermined criteria are met, the system applies the corresponding steering and/or braking actions.

Abstract: A method of guiding a vehicle to a region for initiating a parallel parking maneuver. A region of feasible starting locations for successfully performing a parallel parking maneuver is determined by a processor. A position of the vehicle relative to the region of feasible starting locations is determined. A determination is made whether the vehicle is in a zero heading position. The vehicle is guided along an initial target path by controlling a steering actuator until the vehicle is in a zero heading position relative to the road of travel in response to the vehicle is not in the zero heading position. A planned path is generated that includes two arc-shaped trajectories extending between the vehicle at the zero heading position and a position within the region of feasible starting locations as determined by the processor. The steering actuator is controlled to follow the planned path to the feasible region.

Abstract: A collision avoidance system for assisting a driver in avoiding a collision between a host vehicle and obstacle. A processor recursively calculates a time-to-collision with the obstacle and an optimal collision avoidance path for avoiding the collision. The optimum collision avoidance path is recursively generated based on a position and speed of the host vehicle relative to the obstacle and an updated calculated time-to-collision. A sensing device determines whether the driver of the vehicle has initiated a steering maneuver to avoid the obstacle. A steering assist mechanism maintains the host vehicle along the optimum collision avoidance path. The steering assist mechanism applies a steering assist torque for producing steering adjustments to assist in guiding the host vehicle along the optimum collision avoidance path to the target lane. The steering assist torque generated by the steering assist mechanism is recursively adjusted based on a recent updated optimum collision avoidance path.

Abstract: A method and system may determine, in a vehicle, a desired path around an object based on a location of the object relative to the vehicle, relative speed, road parameters and one or more vehicle parameters. The method and system may calculate one or more vehicle control parameter values which minimize a predicted deviation from the desired vehicle path. The method and system may determine whether the one or more vehicle control parameter values would cause the vehicle to exceed one or more vehicle stability constraints. If the one or more vehicle control parameter values would cause the vehicle to exceed one or more vehicle stability constraints, the one or more vehicle control parameter values may be reduced to one or more vehicle control parameter values not causing the vehicle to exceed the one or more vehicle stability constraints. The method and system may output the one or more vehicle control parameter values to a vehicle automated control device.

Abstract: A process for identifying a vehicle driver according to a pre-determined hierarchy. The process includes determining, in a first determination act, whether a first sub-process, of a group of multiple sub-processes, can be used to identify the vehicle driver. The first sub-process is pre-determined to be a most reliable sub-process of the group for identifying the vehicle driver. The process also includes determining, in a second determination act, only if the first determination act has a negative result, whether a second sub-process of the group can be used to identify the vehicle driver. The second sub-process is pre-determined to be a second-most reliable sub-process of the group for identifying the vehicle driver.

An electrical power steering (EPS) system of a vehicle is monitored for a failure and operation of the lane centering system is switched to a differential braking controller to output differential braking commands to a differential breaking system upon determining that a failure of the EPS system has occurred, where the output braking commands direct the differential braking system to apply force a brake for a wheel of vehicle, such by the applied braking force the vehicle follows a desired path determined for a lane centering operation.
