Abstract: A towing assistance device includes an acquirer, a determiner, and a notifier. The acquirer acquires a coupling angle between a towing vehicle and a towed vehicle. The determiner determines whether the towed vehicle is movable backward in a coupling posture with the coupling angle maintained, when the towing vehicle is moved backward at a current steering angle. The notifier issues information on a steering angle at which the towed vehicle is movable backward in the coupling posture, among selectable steering angles of the towing vehicle.

Abstract: An image display control device according to an embodiment includes a display and a controller. The controller displays a first screen on the display. The first screen includes a first image and a second image. The first image is and image of a vehicle viewed from above. The second image is obtained by capturing a second area that is a part of a first area where is a capturing target around the vehicle. The controller displays, on the display, a third image that is switched from the second image, the third image. The third image is obtained by capturing a third area where is different from the second area. The third is selected as a part of area included in the first area. The controller displays identification information for identifying the third area within the first image, before the second image is switched to the third image.

Abstract: To maintain a suitable vehicle separation between a driven vehicle and a preceding vehicle, a controller predicts a closest approach distance between the driven vehicle and the preceding vehicle on the assumption that the preceding vehicle decelerates at a deceleration detected by a sensor and that the driven vehicle decelerates at a prescribed assumed deceleration after running at a speed detected by the vehicle speed sensor for an idle running time. The controller predicts the speed at the time of closest approach when the separation between the preceding vehicle and the driven vehicle is the closest approach distance. A suitable vehicle separation is determined based on the predicted speed at the time of closest approach and a previously set length of time, and when the predicted closest approach distance is smaller than the suitable vehicle separation, a warning or braking force is generated.

Abstract: In order to maintain a suitable vehicle separation between a driven vehicle with respect to a preceding vehicle, an electric controller 10 predicts a closest approach distance between the driven vehicle and the preceding vehicle on the assumption that the preceding vehicle decelerates at a deceleration detected by a vehicle separation sensor 12 and the like and that the driven vehicle decelerates at a prescribed assumed deceleration after running at a speed detected by the vehicle speed sensor 11 for an idle running time. The electric controller predicts the speed at the time of closest approach when the separation between the preceding vehicle and the driven vehicle is the closest approach distance.

Abstract: A pressure control apparatus is operated to connect a wheel cylinder to a reservoir via a return fluid passage so that brake fluid will be stored in the reservoir to reduce the pressure. In accordance with the operation of a fluid pressure pump, the brake fluid is discharged from the reservoir into the return fluid passage to supply the brake fluid to the wheel cylinder, so that the wheel cylinder pressure is gradually increased. Based on detection of a sharp decrease of the motor load, it is estimated that the reservoir has become empty. Then, brake fluid is taken from a fluid pressure generating apparatus into the wheel cylinder.
