A drive assist apparatus, including a lane-keeping assist apparatus configured to apply an auxiliary steering torque to a steering mechanism mounted on a vehicle so that the vehicle runs at a predetermined position between lane lines, an operating member configured to be operated by an operator of the vehicle to output an activation signal for activating the lane-keeping assist apparatus, a determining unit configured to determine whether operation of the lane-keeping assist apparatus is necessary, and an outputting unit configured to output at least one of a notify signal for prompting the operator to operate the operating member and the activation signal, when the operating member is inoperative and it is determined that operation of the lane-keeping assist apparatus is necessary by the determining unit.

An activity recognition device comprises a port configured to receive a video stream from a video source for a first object and a second object; a memory configured to store instructions and image frames of the video stream; and one or more processors, wherein the one or more processors execute the instructions stored in the memory, the one or more processors configured to: select portions of the image frames based on presence of the first object; determine areas within the portions of image frames, wherein locations of the first object in the video frames are bounded by the determined areas; determine motion of the first object and locations of a second object within the areas of the image frames; and identify an activity according to the determined motion and locations of the second object, and generate an alert according to the identified activity.

Driving support ECU transmits a communication connection request to a help net center HNC when a driver of a vehicle has been determined to be in an abnormal state where the driver loses an ability to drive the vehicle, and when the communication connection to the help net center HNC has been established, the driving support ECU transmits the help signal (the positional information of the vehicle) and decelerates the vehicle at a constant deceleration to make the vehicle stop. On the other hand, when the communication connection to the help net center HNC has not been established, the driving support ECU makes the vehicle travel at a constant speed. Accordingly, it is possible to make the vehicle stop under a situation where the help net center HNC recognizes the vehicle position inside which the driver who has been determined to be in the abnormal state is.

A motorcycle driving assistance device includes: a curve traveling determination unit for determining whether or not an own vehicle is traveling on a curve; a radius-of-curvature calculation unit for, when it is determined that the own vehicle is traveling on a curve, calculating a radius of curvature of the curve; an other-vehicle lane estimation unit for comparing the radius of curvature and a distance between another vehicle and a center of curvature of the curve, and estimating a traveling lane of the other vehicle; and an alarm determination unit for determining whether or not output of an approach alarm is needed, on the basis of a distance between the own vehicle and the other vehicle, a relative velocity of the other vehicle, and a relationship between a traveling lane of the own vehicle and the traveling lane of the other vehicle.

A computer in a vehicle includes a processor programmed to apply, on the vehicle, upon detecting an occupant alertness level below a first threshold, a first periodic component to a first torque applied to one or more first-end wheels and a second periodic component to a second torque applied to one or more second-end wheels.

A vehicle is adapted for movement along a roadway. A cabin of the vehicle is adapted for surrounding and supporting an occupant with movement of the vehicle. Systems of the vehicle control an environment within the cabin.
