摘要： A controller and method for operating a plurality of capacitors of a first phase, wherein the first phase is one of a plurality of phases applied to the motor, a plurality of first switching elements of the first phase, and a plurality of second switching elements of the first phase. The plurality of capacitors charge DC voltage from a battery that applies voltage to the motor. The plurality of first switching elements convert the DC voltage to AC voltage. The plurality of second switching elements switch so that any one of the plurality of capacitors or the plurality of first switching elements is selectively connected to the motor.

摘要： Disclosed are a system for providing event data recorder (EDR) data of a vehicle and a method thereof. The system may include a user terminal and a server. The user terminal may determine a first hash value of a certificate, and transmit the first hash value to a server. The server may receive the certificate and encrypted EDR data from an autonomous driving controller, decrypt, using a public key included in the certificate, a digital signature of the certificate to obtain a second hash value, and, based on a comparison between the first and second hash values, decrypt, using a private key, the encrypted EDR data, and transmit the decrypted EDR data to the user terminal. The user terminal may receive the decrypted EDR data from the server, and provide the decrypted EDR data to a user

摘要： A method and an apparatus for generating a test case (TC) for dynamic verification of an autonomous driving system are provided. The method includes receiving an input signal and generating a temporary TC based on the input signal. A confirmed TC is determined based on a first output signal corresponding to the input signal and a second output signal corresponding to the temporary TC. A final TC is determined by re-arranging the confirmed TC and the final TC is transmitted to an external device.

摘要： A method of updating firmware by a flash bootloader includes: storing current version information included in a trailer block of firmware stored in a flash memory, the firmware including the trailer block and a header block; erasing a sector in which the header block is located while maintaining a sector in which the trailer block is located in the flash memory; writing a header block of a new firmware to be downloaded in the flash memory; determining, by comparing current version information of the new firmware in the written header block and the stored current version information, whether the firmware is to be downgraded; and, in response to determining that the firmware is not to be downgraded, erasing a sector in which the trailer block is located from the flash memory, and writing a trailer block of the new firmware in the flash memory.

摘要： An Ethernet controller for a vehicle includes a Transmission Control Protocol/Internet Protocol (TCP/IP) module configured to continuously transmit a series of data packets having a collective size as large as a set window size or less regardless of receiving acknowledgement (ACK) from a receiver, where the window size is initially set to a window size value acquired from the receiver. The Ethernet controller also includes a window size resetting unit configured to reset the window size to a reduced value when a duplicate acknowledgement (DUP ACK) is received from the receiver.

摘要： A slave node calculates and stores a propagation delay generated when exchanging a message with a master node. The master node transmits a reference time indicated by a hardware clock of the master node, and the slave node synchronizes a hardware clock of the slave node to the reference time indicated by the hardware clock of the master node. The master node transmits a time value in a first time domain to the slave node, where the time value is calculated by the master node by adding an offset of the first time domain to the reference time. The slave node calculates the offset using the time value and the stored propagation delay, and obtains a time in the first time domain by applying the calculated offset to a reference time indicated by the hardware clock of the slave node.
