A vehicle control device has a processor configured to estimate an amount of rainfall per unit time based on an acoustic signal acquired by an acoustical sensor mounted on a vehicle, determine whether a present operation mode of the vehicle is a first operation mode with a lower level to which a driver is contributing to driving or a second operation mode with a higher level to which the driver is contributing to driving than the first operation mode, and decide a first time until the operation mode of the vehicle is transferred from the first operation mode to the second operation mode based on the amount of rainfall, when the operation mode of the vehicle is the first operation mode.

A sound control device has a processor configured to determine whether a driving mode of a vehicle is a first driving mode wherein degree to which the driver participates in driving is low or a second driving mode wherein the degree to which the driver participates in driving is higher, and decide to cause attenuation of predetermined sounds inside the vehicle in a first attenuation mode, using a sound control unit which generates a suppression sound signal for output of suppression sound to cause attenuation of the predetermined sounds, when the driving mode of the vehicle is the first driving mode, or decide to cause attenuation of the predetermined sound inside the vehicle in a second attenuation mode which has a smaller degree of attenuation than the first attenuation mode, when the driving mode of the vehicle is the second driving mode.

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.

A vehicle controller includes a processor configured to detect a vehicle ahead of a host vehicle from time-series sensor signals obtained by a sensor provided on the host vehicle for sensing objects around the host vehicle, track the vehicle ahead detected from the time-series sensor signals, determine whether the vehicle ahead has performed an avoidance action, based on the result of tracking, detect, when the vehicle ahead has performed an avoidance action, a trajectory of an edge of the vehicle ahead opposite a direction of avoidance in the avoidance action, and control travel of the host vehicle so that an edge of the host vehicle opposite the direction of avoidance moves along the detected trajectory.

A vehicle-body front structure that is able to secure collision performance for a collision with a small overlap amount of a collision object with respect to a bumper frame portion is obtained. A vehicle-body front structure includes: paired frame members elongated in a vehicle front-rear direction and arranged side by side in a vehicle width direction; a bumper frame portion elongated in the vehicle width direction and provided over front ends of the paired frame members in the vehicle front-rear direction; and a load transmission member. The load transmission member is placed on an inner side in the vehicle width direction relative to at least one of the frame members so as to be opposed to a load receiving portion placed between the paired frame members from at least one of a front side in the vehicle front-rear direction and an outer side in the vehicle width direction within a range where the load transmission member overlaps with the frame member in a vehicle up-down direction.
