The utility model discloses a manual and electric integrated airplane jack with an electric walking function, which relates to the field of airplane jacks, and comprises a jack main body, three inclined support rods are arranged on the outer wall of the jack main body, cross beams are connected to two sides of the inner part of each inclined support rod, and an oil tank is arranged on each cross beam. The top of the oil tank is provided with a hydraulic motor and a valve body. Moving and lifting of the aircraft jack can be controlled through control of the remote controller, and the aircraft jack can be moved to a jacking point more accurately for operation; meanwhile, manual operation is reserved, the jack can be operated manually under the conditions of electrical element accidents or power shortage and the like, the maintenance task is not affected, the accuracy is improved, the labor intensity is reduced, the safety of equipment is guaranteed, and the working efficiency and the reliability are improved.

The application provides a steering wheel hand-off detection method, a detection device and a vehicle, and belongs to the technical field of steering wheel hand-off detection. The steering wheel hand-off detection method comprises the following steps: obtaining a system return torque value of a steering wheel by learning after power assistance of a steering system of a vehicle; detecting an actual return torque value of the steering wheel in real time; generating a hand-off state signal according to the system return torque value and the actual return torque value; and judging whether the steering wheel is in a hand-off state according to a requested steering angle of the steering wheel, a current steering angle of the steering wheel, the hand-off state signal and the actual return torque value. The steering wheel hand-off detection method can meet the accuracy requirement of function hand-off detection of automatic auxiliary driving.
