Autonomous vehicle intent signaling

Various technologies described herein pertain to controlling an autonomous vehicle to provide indicators that signal a driving intent of the autonomous vehicle. The autonomous vehicle includes a plurality of sensor systems that generate a plurality of sensor signals, a notification system, and a computing system. The computing system determines that the autonomous vehicle is to execute a maneuver that will cause the autonomous vehicle to traverse a portion of a driving environment of the autonomous vehicle. The computing system predicts that a person in the driving environment is to traverse the portion of the driving environment based upon the plurality of sensor signals. The computing system then controls the notification system to output a first indicator indicating that the autonomous vehicle plans to yield to the person or a second indicator indicating that the autonomous vehicle plans to execute the maneuver prior to the person traversing the portion of the driving environment.

A multi-layer control mechanism for optimizing performance metrics of a hybrid electric vehicle (e.g., fuel efficiency, drivability, NVH). A first layer generates a policy that defines target engine & motor operating settings for each of a plurality of possible driver demand inputs based on a predicted driver demand profile for a long-horizon period of time. A second layer determines a predicted “short-horizon” driver demand—based, for example, on historical driver data and one or more environmental sensor inputs—and applies a corrective pre-adjustment to the operating settings of the vehicle in response to determining that a pre-adjustment is required in order to apply the target operating settings for the predicted driver demand. A third layer determines constraints to the operating settings required to comply with the additional performance parameters and limits the operating settings applied to the engine and motor(s) to feasible operating settings defined by the constraints.

A vehicle control apparatus to be applied to a vehicle includes an electric motor, a brake mechanism, and a control system. The control system increases a friction braking force of the brake mechanism while reducing a regenerative braking force of the electric motor, in deceleration traveling performed in a low vehicle speed range where a vehicle speed of the vehicle is less than a first threshold in a state in which an accelerator operation and a brake operation performed by a driver who drives the vehicle are canceled. The control system corrects correlation data between a control instruction value indicated to the brake mechanism and the friction braking force generated by the control instruction value, by using, as a trigger, a situation in which a change rate of a vehicle acceleration of the vehicle exceeds a second threshold in the deceleration traveling in the low vehicle speed range.

Assistance system and method for assisting the driver of a motor vehicle when positioning the motor vehicle at a predefined target position

An assistance system for assisting the driver of a motor vehicle when positioning the motor vehicle at a predefined target position is provided. The target position is preferably a charging position for wireless, in particular inductive, charging of the motor vehicle. In order to position the motor vehicle, the longitudinal movement of the vehicle can be controlled manually by one or more operator control elements (e.g., accelerator pedal, brake pedal) which can be actuated by the driver. The assistance system assists the manual longitudinal control during positioning. The assistance system serves to influence the manual longitudinal control. By influencing the manual longitudinal control, the assistance system counteracts, as a function of the respective position information, the longitudinal movement of the vehicle at least for certain relative positions, in order to bring the vehicle to a stop essentially at the target position.
