A driver assistance device according to an embodiment includes a coupling angle acquirer that acquires a coupling angle between a towing vehicle and a towed vehicle coupled to the towing vehicle; and a notifier that issues a given notification in the towing vehicle when the towing vehicle is driven with the towing vehicle and the towed vehicle differing in orientation at a given value or more based on the coupling angle, the towing vehicle moves in a given distance or less while maintaining a steering angle, and the steering angle of the towing vehicle enables the towing vehicle and the towed vehicle to be placed in a serial state with the towing vehicle and the towed vehicle substantially matching with each other in orientation.

Significant safety advantages are recognized for vehicle-mounted or attached crash attenuators, particularly in the form of structural improvements in the nature of a catch shelf which helps to prevent underride of an impacting vehicle, meaning that the impacting vehicle is less likely to release drop under the attenuator. When an impacting vehicle slides under the crash attenuator, there is an inability to take full advantage of the ride-down afforded by elements of the attenuator as they are crushed by the impact, thus potentially increasing damage to the impacting vehicle and injuries to its occupants.

A trailering assist system includes a receiving device disposed at an equipped vehicle and a trailer camera at a rear of a trailer. When the vehicle is towing the trailer, the trailer camera captures image data and a transmitter at the trailer wirelessly communicates captured image data to the receiving device at the equipped vehicle. The receiving device at the equipped vehicle receives the communicated image data and a display device in the equipped vehicle displays video images derived from the received image data. When another vehicle is towing the trailer, a controller at the trailer determines that the other vehicle is towing the trailer and the transmitter attempts to wirelessly communicate with another receiving device. Responsive to establishing wireless communication with the other receiving device, the transmitter transmits trailer identification information to the other receiving device.

The control device controls a vehicle towing a trailer. The control device is configured to determine whether or not a user is present in the trailer when a shift range is in the parking range. The control device is configured to ignore a shift range switching operation by a driver when the shift range switching operation is performed while a user is present in the trailer.

A device for controlling a directional motion indicator includes a motion detector transmitting a directional motion signal based on a movement and a direction of the movement of the motion detector. A controller includes a controller input port receiving the directional motion signal. The controller determines a backward movement of the motion detector based on the directional motion signal. The controller transmits a motion indicator signal, via a controller output port, based on the determined backward movement of the motion detector.
