Abstract: A system is provided. The system includes a first vehicle controller , a second vehicle controller, and a remote server. The first vehicle controller is programmed to: a) detect an obstacle, b) activate at least one rear-facing sensor to capture a recording of the obstacle; and c) transmit the recording of the obstacle and a location of the first vehicle. The remote server is programmed to a) determine and store a first location of the obstacle, b) subsequent to storing the first location of the obstacle, c) receive a current location of the second vehicle, and d) compare the current location of the second vehicle to the stored first location of the obstacle. The second vehicle controller is programmed to: a) receive the information about the obstacle and b) adjust operation of the second vehicle to avoid the obstacle.

Abstract: A vehicle includes a frame having a left side and a right side, a plurality of wheels including a plurality of left wheels at the left side of the frame and a plurality of right wheels at the right side of the frame, and a vehicle stability system including an actuator device selectively actuated to balance the vehicle on either the plurality of left wheels or the plurality of right wheels while maintaining a space between the other of the plurality of left wheels or the plurality of right wheels and a ground surface.

Abstract: A computer-implemented method for controlling a host vehicle having a vehicle control system that controls motion of the host vehicle relative to a preceding vehicle that is immediately ahead of the host vehicle. The method includes determining a relative headway distance and a relative velocity between the host vehicle and the preceding vehicle, and an acceleration rate of the preceding vehicle. The method includes receiving message packets transmitted from a leading vehicle and the message packets contain parameters of the leading vehicle including an acceleration rate of the leading vehicle. Further, the method includes calculating an acceleration control rate for the host vehicle to maintain the headway reference distance between the host vehicle and the preceding vehicle, based on the relative headway distance, the relative velocity, the acceleration rate of the preceding vehicle, and the acceleration rate of the leading vehicle.

Abstract: Methods and systems are provided for estimating a temperature of a tire. The method includes: receiving tire pressure data; and estimating a temperature of a tread of the tire based on the tire pressure data.

Abstract: A stair-climbing wheelchair comprising deformable main rear wheels comprising lockable suspension elements and front supporting wheels comprising lockable suspension elements is disclosed herein. The wheelchair may operate in at least two modes, a standard mode and a stairs mode. In standard mode, the wheelchair may operate similar to an ordinary basic wheelchair, with suspension elements locked and rigid. In stairs mode, the suspension elements may be activated and the rear wheels may be deformable to readily negotiate an uneven surface, wherein the front suspension elements may be elongated to provide balance while climbing. The operating principles behind the functionality of the device disclosed herein may also be applied to other devices used to negotiate stairs, such as devices used to move heavy appliances on stairs.
