Abstract

The invention discloses a full-automatic parking device of an electric-wheel automobile. The full-automatic parking device comprises wheels, wheel hub motors, lock pin driving mechanisms and a vehicle controller. The wheels are connected to an automobile body by adoption of independent suspension frames. The wheel hub motors are mounted in the wheels and used for driving the wheels to independently rotate. The lock pin driving mechanisms utilize lock pin driving motors to be inserted into or exit out of lock pins at center-line through holes of rear shaft steering transverse pull rods selectively and are used for locking or unlocking the rear shaft steering function. The vehicle controller controls the lock pin driving motors to work, receives all sensor signals and formulates a parking strategy according to the signals so as to control the wheel hub motors to rotate. The parking algorithm is higher in automation degree, under the premise that safety is ensured, the needed space for parking is reduced, and convenience is improved; and certain application prospects are also achieved in traditional automobiles.

Description

technical field

[0001] The invention relates to the technical field of automobiles. More specifically, the present invention relates to a fully automatic parking device and method applied to four-wheel drive in-wheel motor vehicles. Background technique

[0002] With the increasingly serious environmental pollution and the depletion of fossil energy, automobiles are bound to embark on the road of new energy. Currently common electric vehicles are driven by centralized motors, wheel-side motors and hub motors. Among them, the car driven by the wheel hub motor integrates the motor, brake system, even the suspension, and the controller inside the wheel, which greatly simplifies the structure of the car chassis and creates more space for the car. Some traditional car technologies, such as four-wheel drive, Steering in situ, etc., can be easily realized on in-wheel motor-driven vehicles, which greatly reduces technical difficulty. It can be said that hub motor drive is one of ...
