A parking assistance system includes front and rear auxiliary wheel assemblies mounted to a chassis of the vehicle and adjacent front and rear wheels of the vehicle. Each of the front and rear auxiliary wheel assemblies includes two auxiliary wheels and an auxiliary motor coupled to the auxiliary wheels for driving the auxiliary wheels to rotate in a forward or backward direction. A plurality of lift devices are mounted between the auxiliary wheels and the chassis and control upward and downward movement of the auxiliary wheels. At least one parking assistance controller is coupled to the auxiliary motors. A control unit is coupled to the at least one parking assistance controller and manually operable to control a rotating direction and speed of the auxiliary motors via the at least one parking assistance controller, controlling a moving distance and direction of the auxiliary wheels in the forward or backward direction.

The invention discloses a device for automobile parking by side and U turn in situ. The device comprises brackets, turning wheels and an electrical control system thereof. The device is characterized in that the brackets are a pair of fixing mounts on the same level; the turning wheels are a pair of electrical wheels which are arranged on the fixing mounts and can be lifted simultaneously; electrical pushing rods are arranged on the electrical wheels, and the electrical wheels are connected with the electrical pushing rods through a connecting rod at a certain angle; and the corner of the connecting rod is hinged with the fixing mounts. The device is fixedly arranged on the tail of the automobile generally, and can also be arranged on the head and the tail of the automobile simultaneously. The device can finish one-time parking by side at minimum spacing safely and conveniently, reduce parking areas and solve the problem of parking difficulty on the side of the road with a simple structure and at lower production cost. The device can also assist the vehicle in turning or U turning in situ on the road with the radius less than the automobile turning radius.

A vehicle parking assisting system detects an obstacle by sonar devices, and displays it as a present detection position and a past detection point on a display device in an overlapping manner with a combined birds-eye view image. The present detection point is displayed as a series of dots extending from a predetermined position in a fan-shaped detection area in an arcuate shape along a detection area of the sonar devices, and the past detection point is displayed as a single dot located at the predetermined position in the fan-shaped detection area.

The invention discloses a vehicle-mounted mooring system for large and medium-sized captive balloons. The vehicle-mounted mooring system for the large and medium-sized captive balloons comprises a mooring module, a mooring tower module and a tail platform module, wherein through adoption of a square cabin with an internal framework structure, bearing requirements are satisfied and the height in a transporting state does not exceed the limit on the premise of ensuring available working height in the cabin; through adoptions of a rotating and folding type anti-overturning outrigger and a tail extended outrigger which is concealed in a semi-trailer girder, a distance between a front supporting point and a rear supporting point and a distance between a left supporting point and a right supporting point can be greatly increased to satisfy index requirements on wind resistance ability and stability of the large-sized captive balloon and satisfy that the large-sized captive balloon in a folded state can adapt to dimension limitation of highway transportation; and as a telescopic platform is included in the tail platform, a distance between mooring points in front of and behind the mooring system reaches more than 30 m after the tail platform is spliced with the square cabin so that the mooring system can be used for mooring more than 10000 m3 captive balloons. A problem that positional captive balloons cannot be transported to other sites due to suffering geographical limitations of preset positions is solved; and a problem that the use performance and function of the traditional vehicle-mounted captive balloon are limited due to small balloon volume is also solved.
