A system and a method for controlling a low voltage DC/DC converter (LDC) of a hybrid vehicle is provided in which a fuel efficiency mode for artificially turning off pulse width modulation (PWM) control of the LDC is added, thereby improving fuel efficiency. Accordingly, the fuel efficiency mode for artificially turning off the PWM control of the LDC is added, so that when the fuel efficiency mode is performed, power of an auxiliary battery is temporarily supplied to an electric field load, thereby reducing power consumption of a main battery and improving fuel efficiency. Further, when the auxiliary battery is separated, power of the main battery is temporarily supplied to the electric field load by performing the PWM control of the LDC, to prevent a phenomenon that power is not supplied to the electric field load when the auxiliary battery is separated.

The present disclosure relates to a method of preventing drive-by hacking, and an apparatus and a system therefor. A method of preventing drive-by hacking in a vehicle system linked with a vehicle head unit through a communication network in a vehicle may include receiving a predetermined external terminal access notification message reporting access by an external terminal from the vehicle head unit, verifying whether fixed data recorded in an application memory is consistent with fixed data recorded in a backup memory, and transmitting a predetermined hacking detection message to the vehicle head unit based on a result of verification. Therefore, the present disclosure has an advantage of strengthening security of a vehicle when an external terminal is linked with a vehicle head unit.

A system and associated method for calibrating a radar system is described, wherein the radar system includes a phased array antenna including a first antenna array and a second antenna array, a transmitter array, and a receiver array, communication leads, a calibration circuit, and a controller.

The present invention describes a system for an autonomous cargo transport vehicle aiming to provide safety and reliability of autonomous vehicles, regardless of the level of automation and the route or trajectory. Specifically, the present invention comprises a smart system that identifies a road implement for an autonomous tractor vehicle by means of static data from the road implement linked to a target, with a system processor executing control configurations based on the static data. Thus, based on the identification and execution of control configurations, the present invention allows the coupling of the autonomous tractor vehicle to the road implement, transportation of the road implement from one point to another under different levels of automation, so that the processor performs steps of pre-configured decision making, whether predicted or in real time, based on implement data read, to define the best movement route for the autonomous tractor vehicle and/or autonomous tractor vehicle+implement (CVC). The present invention is located in the fields of mechanical engineering, computer engineering, data engineering and robotic engineering, focused on the area of autonomous vehicles.
