Abstract:
In an electric vehicle, an automatic transmission (30) is provided between a differential unit (20) and drive wheels (44). The differential unit (20) includes a motor-generator and a power split device, and the motor-generator is cooled by lubricant of the automatic transmission (30). A battery charger (56) is operable to charge a power storage device (54) using a power supply outside the vehicle. When the temperature of the lubricant is lower than a predetermined temperature upon execution of charging of the power storage device (54) using the charger1 (56), and the automatic transmission (30) is in a neutral state, or a power cutting-off state, the controller (60) rotates the motor-generator of the differential unit (20) so as to perform warming control for raising the temperature of the lubricant.
Abstract:
System for charging the battery (6) of an automotive vehicle furnished with at least one electric or hybrid traction chain comprising an electric machine (2) connected mechanically to the driving wheels and connected electrically on the one hand to an electrical supply network (1) and on the other hand to the battery (6) by way of an inverter (5). The charging system comprises, when the vehicle is on charge, the electric machine (2) and the inverter (5) of the traction chain as well as a control system able to control the inverter (5) so that the energy is tapped off from the electrical supply network (1) through the electric machine (2) and to the battery (6), while controlling the electric machine (2) in such a way that it does not produce any wheel torque.
Abstract:
An apparatus for guiding an autonomous vehicle towards a docking station comprising an autonomous vehicle provided with a camera-based sensing system, a drive system for driving the autonomous vehicle, and a control system for controlling the drive system. The apparatus further includes a docking station including a first fiducial marker and a second fiducial marker, wherein the second fiducial marker is positioned on the docking station to define a predetermined relative spacing with the first fiducial marker, wherein the control system is operable to receive an image provided by the camera-based sensing system, the image including a representation of the first and second fiducial markers, and to control the drive system so as to guide the autonomous vehicle towards the base station based on a difference between the representation of the first and second fiducial markers in the received image and the predetermined relative spacing between the first and second fiducial markers.
Abstract:
The invention relates to a system and power allocation method that maintains proportional-share fairness of energy distribution to competing consumers. The system consists of a renewable energy source with a fluctuating power output, and users with shares in the system and stochastic continuous power loads. The method periodically re-computes power rates allocated to each connected load considering users' shares in the system, current power demand and generation and users' historic energy consumption patterns. The rate computation is based on an optimization problem that maximizes the allocated power respecting current generation and minimizes the difference in energy distributed to different users.
