Abstract: Method and systems are provided for adjusting an engine torque in response to changes in a desired engine torque. In one example, a method may comprise responsive to increasing desired engine torques, monotonically decreasing an alternator torque to a first level from a second level when not injecting fuel to engine cylinders, and stepping up the alternator torque from the first level to the second level while initiating engine combustion, and then monotonically decreasing the alternator torque from the second level to the first level in response to the alternator torque reaching the first level. In this way, a method may comprise adjusting a load exerted on an engine by an alternator mechanically coupled to said engine during both cylinder combustion, and during non-fueling conditions.

Abstract: A vehicle system includes a user interface device and an autonomous mode controller. The user interface device receives a user input representing a driving mode selection. The autonomous mode controller commands one or more vehicle subsystems to operate in accordance with characteristics associated with the driving mode selection. Examples of characteristics can include how aggressively the vehicle accelerates or decelerates, a minimum distance from the vehicle to a front vehicle, or how frequently the vehicle changes lanes, among others.

Abstract: A driver training vehicle system includes a driver training vehicle and an interface system with an auxiliary control unit that is removably installable in the vehicle. A vehicle control system can receive a brake input from a vehicle driver via a floor pedal in the vehicle as well as a brake input from a vehicle passenger via the auxiliary unit. The control system adjusts an engine torque and a brake torque based on the received brake inputs to decelerate the vehicle.

Abstract: Data is collected from vehicle sensors to generate a virtual map of objects proximate to the vehicle. Based on the virtual map, an in-vehicle computer determines a traffic condition in front of and behind a host vehicle. The in-vehicle computer determines collision avoidance maneuvers. The computer instructs vehicle control units to implement the collision avoidance maneuvers. The computer may additionally or alternatively communicate the collision avoidance maneuvers to a driver via an interface. In the case of unavoidable collisions, the computer determines and initiates damage mitigation actions.

Abstract: A vehicle sub-system controller is configured to receive a first message and a second message, wherein the first message includes at least a command for the controller, and the second message includes at least a target value for the controller to achieve. A fault may be detected with respect to the first message; and an adjustment to the sub-system may be locally determined in the sub-system controller to achieve the target value.

Abstract: Methods and systems are provided for improving surge control. When surge conditions are approached, a reference governor reduces engine airflow at a slower rate and to a higher level than the engine airflow required to meet the reduced torque demand. The excess torque resulting from the extra airflow is offset by applying a negative torque on the driveshaft via an electric machine coupled to the engine or via alternate engine actuator adjustments.
