Patent number: 12233862Abstract: A driver assistance device acquires information about vehicle-driving environment ahead of the vehicle to detect an intersection. Upon determining that the vehicle makes a right- or left-hand turn at the intersection, the driver assistance device sets a projected course of the vehicle and recognizes a moving object ahead in a direction in which the vehicle making a right- or left-hand turn is headed. The driver assistance device calculates a movement vector from positional changes of the moving object to calculate a meeting point of a path of the object and the projected course. When an interval between times at which the vehicle and the moving object reach the meeting point is found to fall within a predetermined range, the driver assistance device determines that there is a possibility of interference between the vehicle and the moving object and then causes the vehicle to halt short of the meeting point.Type: GrantFiled: December 16, 2022Date of Patent: February 25, 2025Assignee: SUBARU CORPORATIONInventors: Hideki Sugawara, Takahiro Furuya, Anfen Ye, Kazuki Yamaguchi, Wataru Matsudate, Hayato Hori, Takayuki Sato

Patent number: 12227174Abstract: A vehicle traveling control apparatus includes a sensor and a traveling control processor configured to function as an identification unit and a tentative identification calculation unit. The identification unit identifies whether the target detected by the sensor is a ghost or a real object based on results of the detection for first number of measurement cycles, and if the target is the real object and a possibility that the target and the vehicle come into contact with each other is present, causes a first traveling control to be executed. The tentative identification calculation unit determines whether the target is the ghost or the real object based on results of the detection for second number of measurement cycles, and when the target is the ghost and the possibility is present, causes a second traveling control to be executed. The second number is less than the first number.Type: GrantFiled: January 3, 2023Date of Patent: February 18, 2025Assignee: SUBARU CORPORATIONInventors: Hideki Sugawara, Takahiro Furuya, Anfen Ye, Kazuki Yamaguchi, Wataru Matsudate, Hayato Hori, Takayuki Sato, Ryo Nakagawa

Publication number: 20250038502Abstract: An electric junction box is equipped with a special simplified power supply. An internal circuit of the electric junction box supplies the output of the simplified power supply as an operating voltage of a DC/DC converter to start the DC/DC converter when battery exhaustion occurs in the low voltage battery. When the DC/DC converter is started, high voltage power stored in a high voltage battery on the vehicle can be stepped down and supplied to a circuit on the low voltage battery, thereby enabling normal starting operations such as starting an engine. An emergency start mode can be selected by a switch operation of a user or by automatic detection of a drop in power supply voltage.Type: ApplicationFiled: October 10, 2024Publication date: January 30, 2025Inventors: Hayato Yamaguchi, Sadaharu Okuda, Taku Furuta, Junya Kato, Ryoichi Murata

Publication number: 20250018832Abstract: When a low voltage battery is exhausted, power necessary for starting up is supplied from a simple power supply connected to an ACC socket to a vehicle side. The power of the simple power supply is supplied to power supply terminals of a DC/DC converter and other loads, and is used to activate the DC/DC converter. After the DC/DC converter is activated, power on a high voltage battery side is stepped down and supplied to a low voltage battery side, and a power supply path for the DC/DC converter and the other loads is switched. A mode switch or a relay is used to switch between a normal mode and an emergency start mode.Type: ApplicationFiled: September 27, 2024Publication date: January 16, 2025Inventors: Hayato Yamaguchi, Sadaharu Okuda, Ryoichi Murata

Publication number: 20240388082Abstract: In a power supply system, a voltage monitor detects a voltage of output power output from a DC/DC converter. A step-down unit steps down the voltage of the output power and supplies the output power to a load. A distributor control unit controls the step-down unit based on the voltage detected by the voltage monitor. In a power satisfaction state in which the voltage detected by the voltage monitor is equal to or higher than a predetermined threshold voltage, the distributor control unit controls the step-down unit to step down the voltage of the output power and supply the output power to the load. In a power shortage state in which the voltage detected by the voltage monitor is less than the threshold voltage, the distributor control unit controls the step-down unit to supply the output power to the load without stepping down the voltage of the output power.Type: ApplicationFiled: April 1, 2024Publication date: November 21, 2024Inventors: Hayato Yamaguchi, Sadaharu Okuda

Publication number: 20240383373Abstract: In a power supply control device, a control unit is switchable between a drive mode, in which a drive current flows from a battery to load units and the control unit, a standby mode, in which the drive current is interrupted and a dark current flows, and an interruption mode, in which the dark current is interrupted. When a charge level of the battery detected by a battery sensor is lower than or equal to a dark current interruption threshold in the standby mode, a relay control unit of the control unit switches a relay to interrupt the dark current flowing from the battery to the load units and the control unit and switch from the standby mode to the interruption mode.Type: ApplicationFiled: May 8, 2024Publication date: November 21, 2024Inventors: Ryoichi Murata, Sadaharu Okuda, Hayato Yamaguchi
