Summary of the patent applications from Hyundai Motor Company on November 30th, 2023

Hyundai Motor Company has recently filed several patents for various technologies. These patents cover areas such as power saving in sidelink communication, video coding methods, generating prediction blocks in video encoding, communication network systems, sensorless induction motor systems, metal-carbon dioxide batteries, valve opening/closing detection devices for fuel cell systems, dialogue systems, vehicle control methods, and vehicle recommendation systems.

In the power saving patent, Hyundai describes a method for saving power in sidelink communication using a DRX-based method. This involves transmitting information about PSFCH intervals to a terminal, determining an SL DRX cycle based on these intervals, and transmitting the SL DRX cycle information to the terminal.

The video coding patent introduces a method and device that simplify the video coding process and improve efficiency by performing intra prediction of subblocks without unnecessary parsing of the intra-prediction mode. It also revises the prediction mode or reconstruction order when intra-predicting subblocks divided from the current block.

The patent for generating prediction blocks in video encoding involves using a weighted-sum of an intra-prediction signal and an inter-prediction signal. The current block of video data is split into subblocks, each assigned a weight set. The prediction block is determined based on a weighted-sum of the intra-prediction signal and the inter-prediction signal, with the specific weighted-sum depending on the weight set assigned to each subblock.

The communication network system patent describes a system that enables communication between CAN and Ethernet networks. It includes a CAN controller, a gateway that generates conversion messages for Ethernet communication based on predetermined conversion determination data, and an Ethernet controller that receives these messages.

The sensorless induction motor system patent presents a motor control method that predicts the time required for the rotor to stop when the motor is commanded to stop. After the predicted stop waiting time, the controller applies a pulse voltage to each phase of the stator multiple times and determines that the rotor has stopped when the minimum deviation value of an induced current is equal to or greater than a reference value.

The metal-carbon dioxide battery patent describes a battery system for generating hydrogen and storing carbon dioxide. It consists of two plates, a separator, a spacer, anode sheets, a pressing unit, and a cathode, all arranged in a specific configuration.

The valve opening/closing detection device patent introduces a device that detects the opening and closing of a valve in a fuel cell system without the need for a separate sensor. It accurately detects the valve's time points based on the fluctuation range of the differential value of the current supplied to the valve.

The dialogue system patent describes a system that can understand and respond to user speech. It includes a database, a speech recognition device, a natural language understanding device, and a controller that generates additional query instructions based on the main domain and task determined from the user's speech.

The vehicle and control method patent involves a controller that can determine when the driver is getting out of the vehicle by analyzing state information. It can also determine the use state of the vehicle's battery based on the driver's getting-off state and generate a control signal to send a warning message to the driver's terminal.

The vehicle recommendation system patent aims to provide personalized vehicle recommendations based on a user's preferences and tendencies. It includes devices that assess a user's preferences, analyze various tendencies of different vehicles, and generate a tendency matching index to indicate how well a user's preferences align with the tendencies of each vehicle.

Notable applications:

• Power saving in sidelink communication using a DRX-based method.
• Simplified video coding method and device using subblock partition-based intra prediction.
