Abstract: An operator offset request for automatic lane following system of an automobile vehicle includes an operator offset request defining a lateral offset distance away from a first travel-line of an automobile vehicle in a displacement path moved until a second travel-line of the automobile is achieved. An operator input setting system when actuated generates an initiation signal forwarded to a controller to input the operator offset request. An achievement signal is generated to signify a selected offset position selected by a vehicle operator for the offset distance is achieved. A vehicle return travel path is elected by the vehicle operator to return the automobile vehicle to the first travel-line from the second travel-line by a return displacement path which is opposite to the displacement path.

Abstract: In various embodiments, methods, systems, and vehicle apparatuses are provided. A method for implementing phases of steering override control in a vehicle using a Deep Neural Network (DNN) including receiving, by a steering assist unit disposed of in the vehicle, a set of vehicle inputs including lane data and vehicle sensor interpretation information and driver steering input; configuring a mission planning module to determine a desired path of the vehicle; configuring a vehicle path prediction module to determine a set of a predicted dynamics of the vehicle; configuring a driver override determination module in communication with the DNN to override the automated steering control torque based on a phase of steering control operation and by information of a corresponding intervention phase classified in the DNN, and configuring a lateral control module to override the steering control torque for automated steering assist based on a determined phase of steering control operation and driver input such as driver steering torque and torque rate.
