Abstract: Provided is a gas sensor including a housing made of metal through which a sensor element is inserted and an outer cylinder made of metal welded to an outer periphery of the housing, in which generation of pinholes on a surface of a welded portion is suppressed. In a gas sensor according to one aspect of the present invention, a contact distance Lg, which is a length in an axial direction of an outer peripheral surface of a housing in contact with an inner peripheral surface of an outer cylinder on a rear end side with respect to a molten portion of the outer cylinder formed by welding, is equal to or less than a reference distance Lr.

Abstract: A vehicle controller includes a collision detector, a braking controller, a motional state detector, and a minor collision determiner. The collision detector is configured to detect a collision between a vehicle and another object. The braking controller is configured to cause a braking device of the vehicle to generate a braking force in accordance with the detecting of the collision by the collision detector. The motional state detector is configured to detect a motional state of the vehicle. The minor collision determiner is configured to determine, based on an output from the motional state detector, that a minor collision occurs that is a collision not detected by the collision detector. The braking controller is configured to cause the braking device to generate the braking force if the collision detector does not detect the collision and the minor collision determiner determines that the minor collision occurs.

Abstract: A vehicle control apparatus includes a braking controller individually controlling braking forces of braking devices for left and right front and rear wheels, a side collision detector detecting a side collision against a vehicle, and a yaw behavior detector detecting yaw behavior of a vehicle body. If the yaw behavior detected after the side collision is such that a rear of the vehicle body shifts away from a collision side relative to a front thereof, the braking controller executes yaw amplification control to cause the braking device for the collision-side front wheel to generate a braking force larger than the remaining wheels. If the detected yaw behavior is such that the front shifts away from the collision side relative to the rear, the braking controller executes the yaw amplification control to cause the braking device for the collision-side rear wheel to generate a braking force larger than the remaining wheels.
