Abstract

A computer implemented method for controlling a load aggregator for a grid includes receiving a predicted power demand over a horizon of time steps associated with one of at least two buildings, aggregating the predicted power demand at each time step to obtain an aggregate power demand, applying a learnable convolutional filter on the aggregate power demand to obtain a target load, computing a difference between the predicted power demand of the one building with the target load to obtain a power shift associated with the one building over the horizon of time steps, apportioning the power shift according to a learnable weighted vector to obtain an apportioned power shift, optimizing the learnable weighted vector and the learnable convolutional filter via an evolutionary strategy based update to obtain an optimized apportioned power shift, and transmitting the optimized apportioned power shift to a building level controller associated with the one building.

Abstract

A method for operating a driver assistance function to support a lateral control of a vehicle is provided. A permissible range for a steering torque component which the driver assistance function is able to exert on the steering of the vehicle is predefined. The permissible range is specified by upper and lower limits. The upper and lower limits of the permissible range be adapted as a function of a current vehicle state. The vehicle state is given relative to a lane center, for example, by the position, the velocity, the acceleration and the sudden motion, by the respective component of this variable in the lateral direction. An adjustable range of the driver feedback is determined based on the vehicle state and the lateral acceleration. From this and the consideration of a disturbance compensation, the permissible range of the steering torque component of the assistance function is ascertained.

Abstract

A virtual visor system is disclosed that includes a visor having a plurality of independently operable pixels that are selectively operated with a variable opacity. A camera captures images of the face of a driver or other passenger and, based on the captured images, a controller operates the visor to automatically and selectively darken a limited portion thereof to block the sun or other illumination source from striking the eyes of the driver, while leaving the remainder of the visor transparent. The visor system advantageously detects certain combinations of facial expression and head gestures from which an error or issue with the operation of the visor system can be inferred. In response to such designated combinations of head gestures and facial expressions, the visor system adapts one or more operating or calibration parameters of the visor system to provide more accurate updates to the optical state of the visor.

Abstract

A virtual visor system is disclosed that includes a visor having a plurality of independently operable pixels that are selectively operated with a variable opacity. A camera captures images of the face of a driver or other passenger and, based on the captured images, a controller operates the visor to automatically and selectively darken a limited portion thereof to block the sun or other illumination source from striking the eyes of the driver, while leaving the remainder of the visor transparent. The visor system advantageously predicts future positions of the head or eyes of the driver when the driver’s head is in motion. Based on the predictions, the optical state of the visor is updated proactively to anticipate future movements of head of the driver. In this way, some of the negative effects of measurement and processing latencies are mitigated when responding to rapid head motions.

The virtual visor system advantageously updates the optical state with blocker patterns that including padding in excess of what is strictly necessary to block the sunlight. This padding advantageously provides robustness against errors, allows for a more relaxed response time, and minimizes frequent small changes to the position of the blocker in the optical state of the visor.

Abstract

A hydrostatic traction drive includes a hydrostatic pump and a hydrostatic motor connected to each other in an open circuit. One of the pump and motor is pressure-regulated while the other is torque-controlled or regulated in terms of pivot angle. A braking mode is therefore possible in which the secondary-side braking torque can be adapted to the permissible primary-side supporting torque of a primary machine coupled to the pump. To further increase the braking power, even in a high rotational phase of the primary machine, the permissible drag torque thereof can be temporarily exceeded. To further increase the braking power and therefore to have high-performance braking during operation, further means for converting energy can be provided in order to adjust a secondary-side braking torque and a primary-side supporting torque independently of each other.

Abstract

A virtual visor system is disclosed that includes a visor having a plurality of independently operable pixels that are selectively operated with a variable opacity. A camera captures images of the face of a driver or other passenger and, based on the captured images, a controller operates the visor to automatically and selectively darken a limited portion thereof to block the sun or other illumination source from striking the eyes of the driver, while leaving the remainder of the visor transparent. The virtual visor system advantageously detects whether the driver of other passenger is performing particular head gestures and updates the optical state of the visor using suitable modified procedures that accommodate the intent or goals of the driver or other passenger that are inferred from the predefined head gesture. In general, the modified procedures reduce distracting or frustrating updates to the optical state of the visor.
