  • Patent number: 11987238
    Abstract: A driving support apparatus according to the invention estimates the position of a moving body by controlling a position estimation unit when the tracking-target moving body leaves a first area or a second area to enter a blind spot area and detects the position of the moving body by controlling a position detection unit when the moving body leaves the blind spot area to enter the first area or the second area. In this manner, the trajectory of the tracking-target moving body is calculated so that the trajectory of the moving body detected in the first area or the second area and the trajectory of the moving body estimated in the blind spot area are continuous to each other and driving support is executed based on the calculated trajectory of the tracking-target moving body.

  • Patent number: 11987298
    Abstract: A main power supply having a large capacity and a backup power supply having a small capacity are switchable by a power supply switching determination unit in a system. A motor control device drives a motor by the main power supply or the backup power supply. A drive control unit outputs a drive signal, calculated by feedback control of the current detection value with respect to the current command value, to an inverter circuit. When the power supply switching determination unit switches from the main power supply to the backup power supply, the drive control unit moves from a normal control using the main power supply to a backup control that restricts an electric power consumption and prevents the backup power supply from stopping.

  • Publication number: 20240157800
    Abstract: In a vehicle drive system, in at least either of a case where a first ECU receives a collision detection signal or a case where an interlock line is disconnected, the first ECU controls a relay such that electrical connection between a battery and a motor device is disconnected. The motor device includes an electric motor for traveling, a PCU, a second ECU, and a backup power supply. The PCU includes one or more capacitors. When the interlock line is disconnected, the second ECU is activated by electric power supplied from the backup power supply activated along with the disconnection. Under the condition that the second ECU does not receive, from the first ECU, a discharge command to discharge residual charge or that a determination that a collision occurs is made, the second ECU controls the PCU such that the PCU executes a discharge control.

  • Publication number: 20240162585
    Abstract: A power storage cell includes: an electrode assembly; a cell case; and an external terminal. The cell case has a case main body and a lid. The lid has a lid main body charged positively or negatively, an inversion plate that is able to short-circuit the lid main body and the external terminal, and a protrusion protruding from the inversion plate toward the external terminal. The inversion plate is deformable between a steady-state shape and an inversion shape, the steady-state shape being a shape curved to project in a direction away from the external terminal, the inversion shape being a shape curved to project toward the external terminal with the inversion plate being in contact with the external terminal. The external terminal has a holding portion that holds the protrusion when the inversion plate is in the inversion shape.
