Abstract: An electronic control device 140 is mounted on an on-vehicle control system 10 that performs travel control of an automobile, and is communicatively connected to a plurality of control devices including a first control device (electronic control device 120) and a second control device (electronic control device 130). The electronic control device 140 includes an attack determination unit 145 that determines presence or absence of a security attack in each control device, and a redundant system execution determination unit 146 that determines whether to cause the second control device to execute a redundant function similar to or a part of the function performed by the first control device based on the result of determination by the attack determination unit 145.

Abstract: A vehicle front structure includes: an air guide member arranged behind an opening of a front bumper to guide rearward ambient air taken through the opening; a radar attached to an upper front grille; and a grille support member arranged behind the radar and extending substantially horizontally in a vehicle front-rear direction, wherein a front end of the grille support member is fixed to the upper front grille, and a rear end of the grille support member is fixed to the air guide member.

Abstract: A vehicle body front construction includes: a front bumper including an opening; an air guide member disposed behind the front bumper and configured to guide rearward outside air taken from the opening; and a sensor attached to the front bumper; and a sensor protection member disposed between the sensor and the air guide member. The sensor protection member includes: a protection wall extending in a width direction of a vehicle with a clearance between the sensor protection member and the air guide member; and a side wall extending forward from an end of the protection wall close to the opening. The side wall includes a front end positioned close to the front bumper.

Abstract: A vehicle body for contributing to weight reduction of a structure of a front part while preventing a front bumper beam from falling off is provided. A vehicle body includes: pairs of left and right support bodies, being disposed on the left and the right with an accommodation space of a power unit interposed therebetween, extending in a vehicle body forward-rearward direction, and having joint surfaces displaced rearward as the joint surfaces going outward in a vehicle width direction while facing the front; a front bumper beam, extending in a vehicle body lateral direction across the front of the accommodation space and being joined to the joint surfaces at both ends thereof; and engagement members, extending forward from inner sides of the joint surfaces in the vehicle width direction and engaging with the front bumper beam in the forward-rearward direction at least at a time of a collision.

Abstract: A vehicle body structure includes a bumper beam extending in a vehicle width direction, and a pair of right and left bumper beam mounting members each disposed at an outer side in the vehicle width direction of a back face of the bumper beam and mounting the bumper beam on a front side frame. The bumper beam includes a first displacement promoting part that is provided at a mounting part for the bumper beam and the bumper beam mounting members and capable of promoting displacement of the bumper beam by a collision load. The bumper beam mounting member includes a second displacement promoting part that is provided at the mounting part and capable of promoting displacement of the bumper beam by a collision load.

Abstract: Provided is a vehicle body structure capable of preventing separation between a bumper beam and a bumper beam mounting member on the non-collision side at the time of an offset collision. The vehicle body structure includes a bumper beam, a pair of bumper beam mounting members, and a pair of holding members. The holding member includes an outer mounting portion for mounting an outer side in the vehicle width direction of the holding member on the bumper beam mounting member, and a front mounting portion for mounting an inner side in the vehicle width direction of the holding member on the front surface portion of the bumper beam. The front mounting portion extends to a position corresponding to a vehicle width direction inner end portion of the bumper beam mounting member in a front-rear direction at least on the front surface portion of the bumper beam.

Abstract: A vehicle upper body structure includes a roof panel, a roof arch that extends across the roof panel in a vehicle width direction and that is joined to a lower surface of the roof panel, and a roof antenna disposed on an upper surface of the roof panel. The roof arch includes a first roof arch and a second roof arch disposed in front of the first roof arch. An antenna bracket that allows the roof antenna to be mounted thereon extends frontward from a midpoint of the first roof arch in the vehicle width direction or a vicinity of the midpoint. The antenna bracket supports the roof panel, and the second roof arch is disposed so that as viewed from above the vehicle body, at least part of the second roof arch extends between right and left rear pillars.
