  • Publication number: 20200395798
    Abstract: Disclosed is a rotor for a spoke motor, in which both rare-earth magnets and ferrite magnets are arranged in series, the rare-earth magnet has a smaller size than the ferrite magnet, and a small amount of rare-earth magnet is used, such that manufacturing costs may be greatly reduced, an efficient output may be produced, the motor may produce a higher output than a spoke motor model using only the ferrite magnet, and the motor may use a smaller amount of rare-earth magnet than an IPM type motor model, but may produce an output at a similar level to that of the IPM type motor model.

  • Publication number: 20200174920
    Abstract: Disclosed herein are a method and apparatus for randomizing the address space layout of an embedded system based on hardware. The method is configured such that the hardware loader of the embedded system randomly arranges the respective address regions of multiple peripheral devices and memory using a random number each time a program is loaded, such that the respective random start addresses of the multiple peripheral devices and the memory, which are set based on the randomly arranged address regions, are recorded in an address table, and such that program code loaded into the memory is reengineered based on the address table so as to match the randomly arranged address regions.

  • Publication number: 20200169392
    Abstract: Disclosed is a system for performing key management of an in-vehicle network. The key management system of the in-vehicle network includes a reception unit configured to receive a shared secret key of a central gateway and a domain gateway, a memory configured to store a program for performing key management of the in-vehicle network using the shared secret key, and a processor configured to execute the program. The processor generates a secret key to be stored in a node of the in-vehicle network using the shared secret key and a unique ID of the node.

  • Publication number: 20200169555
    Abstract: A transmission method of a domain gateway over a vehicle network based on automotive Ethernet includes receiving, by a domain gateway of a first domain, transmission data on a CAN packet basis from a transmitting-side ECU; transmitting, by the domain gateway of the first domain, the transmission on an Ethernet packet basis to a domain gateway of a second domain; and transmitting, by the domain gateway of the second domain, the transmission data on a CAN packet basis to a receiving-side ECU. The CAN packet includes a CAN ID field, and the CAN ID field includes a CAN message section and an authentication section.

  • Publication number: 20200014068
    Abstract: An energy storage device comprising a first electrode and a second electrode, wherein at least one of the first electrode and the second electrode comprises a self-supporting composite material film, a separator between the first electrode and the second electrode, and an electrolyte in contact with the first electrode, the second electrode, and the separator, wherein the electrolyte comprises at least one of a fluorine-containing cyclic carbonate, a fluorine-containing linear carbonate, and a fluoroether. The composite material film having greater than 0% and less than about 90% by weight of silicon particles, and greater than 0% and less than about 90% by weight of one or more types of carbon phases. At least one of the one or more types of carbon phases can be a substantially continuous phase that holds the composite material film together such that the silicon particles are distributed throughout the composite material film.
