Publication number: 20240067233Abstract: When an object that may possibly collide with a vehicle is detected from a sensor signal of one of sensors mounted on the vehicle, a vehicle controller changes the level of autonomous driving control applied to the vehicle from a first level that does not require a driver to operate an accelerator and steering and does not require the driver to look around the vehicle to a second level that requires the driver to look around the vehicle but does not require the driver to operate an accelerator and steering. When an object that may possibly collide with the vehicle is detected from sensor signals of two or more of the sensors, the vehicle controller changes the level of autonomous driving control from the first level to a third level that requires the driver to operate at least an accelerator or steering.Type: ApplicationFiled: August 14, 2023Publication date: February 29, 2024Inventors: Wataru Kawashima, Ryusuke Kuroda, Kenichiro Aoki, Takehiko Hanada, Takuya Fujiki
