  • Publication number: 20160297280
    Abstract: An energy-efficient thermal management system for an electric or hybrid vehicle is provided. The system has a first coolant circuit for controlling the temperature of electric components of an electric powertrain, an air-conditioning unit being provided for air-conditioning an interior. A second coolant circuit air-conditions the interior and is operable independently of the first coolant circuit. Each coolant circuit comprises a pump and a respective ambient heat exchanger. In order to control the temperature of the interior, a temperature control device which can be designed as a Peltier module is integrated into the second coolant circuit, said temperature control device operating in the manner of a heat pump for heating purposes. The two coolant circuits can be coupled to each other in order to exchange heat. An additional temperature control device can be integrated in order to air-condition an interior component in a decentralized manner, in particular a seat.

  • Patent number: 7586933
    Abstract: The invention concerns a network comprising an interconnecting network and several network nodes that are coupled to said interconnecting network and are designed to adapt their local communication time schedule to the communication time schedule of at least one other network mode, prior to being integrated as active network nodes. A network node to be integrated checks the activity of other network nodes and if no activity is identified, sends out positional messages for other network nodes, said message being fixed by predetermination in its communication time schedule. If a network node cannot be integrated as a reference node, it can only be integrated as an active node if it adapts its local communication time schedule to that of the reference node after receiving positional messages and if a check as to whether its own communication time schedule agrees with the communication time schedules of at least some of the active network nodes proves positive.
