  • Publication number: 20240166175
    Abstract: Provided is a driver error response system with which it is possible to further increase safety during a driver error. This driver error response system has a switch operated during an error of the driver, an electronically controlled braking system that can execute automatic braking, a vehicle-external output unit that informs the outside of the vehicle that the driver error response system is operating, and a control unit that turns on the electronically controlled braking system and the vehicle-external output unit when at least the switch is operated, the control unit continuing the ON operation of the electronically controlled braking system when a part related to the driver error response system fails during the operation of the driver error response system.

  • Publication number: 20240027696
    Abstract: An optical connection structure including first optical fibers, second optical fibers, a first optical connector, and a second optical connector is disclosed. The first optical connector is configured such that each of first distal end portions of the first optical fibers protrudes from a first front end surface to the outside when the first optical connector and the second optical connector are connected to each other. Each of the first distal end portions is inserted into a corresponding second fiber hole of the second optical connector. The second optical connector is configured such that each of second distal end portions of the second optical fibers is moved rearward inside second fiber holes due to each of the first distal end portions respectively inserted into the second fiber holes. The first optical fibers and the second optical fibers are optically coupled to each other inside the second fiber holes.
