    摘要： An electric vehicle structure includes a drive system, a front lateral member and a rear upper lateral member. The front and rear lateral members are elongated in a lateral direction of a vehicle and spaced apart from each other in a forward-rearward direction of the vehicle with the drive system interposed therebetween. The vehicle structure further includes a rear lower lateral member elongated in the lateral direction of the vehicle and disposed beneath a motor of the drive system.

    摘要： An embodiment system for identifying a controller causing an electrical discharge of a vehicle includes a signal delay unit communicatively connected to controllers within the vehicle and configured to transmit a wake-up trigger signal after a predetermined first time passes when the wake-up trigger signal is input from a first controller among the controllers, and a microcontroller unit configured to enter into a wake-up mode after the first time passes when the microcontroller unit is in a sleep mode and the wake-up trigger signal is received through a single-channel transceiver connected to the first controller and store an identification of the first controller when the wake-up trigger signal is received from the signal delay unit.

    摘要： Disclosed is a segmented magnet which may adjust the application direction of a heavy rare earth element for grain boundary diffusion depending on the magnetization direction of the segmented magnet so as to simplify the manufacturing process of the segmented magnet while reducing eddy current loss, and a method for manufacturing the same. The method includes preparing a plurality of permanent magnet parent bodies having a constant magnetization direction, diffusing a diffusion material into the prepared permanent magnet parent bodies via a pair of planes thereof opposite each other and parallel to the magnetization direction along grain boundaries so as to form a pair of diffusing surfaces, preparing a permanent magnet assembly by stacking the permanent magnet parent bodies in a line such that the diffusing surfaces thereof face each other, and segmenting the permanent magnet assembly into a plurality of pieces along planes perpendicular to the magnetization direction.

    摘要： An over-the-air (OTA) update apparatus includes a communication device that receives data for an OTA update of software for vehicle from a server and a processor that calculates an expected update current consumed by a controller loaded into a vehicle in an additional OTA update proceeding subsequently, based on current consumption consumed in an OTA update of the controller, determines an update factor to be proportional to the expected update current, and proceeds with the additional OTA update based on that the update factor is less than or equal to a predetermined threshold.
