Description
Technical field
The present invention relates to a kind of turn round device for automobile in site, belong to vehicle electric field.
Background technology
Now, the phenomenon of road traffic congestion is on the rise, and especially in some big cities, car owners drive very tired, if run into some narrow road sections, the car owner with vehicle turn around need to be repeatedly reversing and advance many times, very difficult.In order to address this problem, proposed some turn round device for automobile in sites, but present turning back of car apparatus structure to be too complicated, and not to detect the means (for example slope) of extreme terrain, if blindly turn around and to cause danger.
Summary of the invention
Problem to be solved by this invention is the defective that exists for prior art, proposes a kind of simple in structure, safe and reliable turn round device for automobile in site.
The present invention adopts following technical scheme for solving above technical matters:
A kind of turn round device for automobile in site comprises power circuit, main control unit, hydraulic pressure lifting apparatus, slewing arrangement, joystick, CAN bus communication module, the first obliquity sensor, the second obliquity sensor, A/D modular converter, collecting sensor signal circuit and several ultrasonic transduters that are positioned at the vehicle right and left both sides; Described hydraulic pressure lifting apparatus and slewing arrangement are positioned at the bottom of car center; Described hydraulic pressure lifting apparatus and slewing arrangement are connected by data line with main control unit respectively; Described CAN bus communication module is connected by signal wire (SW) with main control unit; Described the first obliquity sensor and the second obliquity sensor are connected with the signal input part of main control unit by the A/D modular converter respectively; Described ultrasonic transduter is connected with the signal input part of main control unit by the collecting sensor signal circuit; Described joystick is connected with the signal input part of main control unit.
As further prioritization scheme of the present invention, comprise that also Warning light driving circuit and several are positioned at the Warning light of vehicle outer side; Described Warning light is connected with the signal output part of main control unit by the Warning light driving circuit.
The present invention adopts above technical scheme, compared with prior art has following technique effect:
The mode that the present invention works in coordination by hydraulic pressure lifting apparatus and slewing arrangement realizes the turning back of car function, and principle is simple.
The present invention is provided with the first obliquity sensor and the second obliquity sensor is respectively used to detect automobile at the inclined degree of X-direction and Y direction, when automobile when slope or other are not reposefully on shape, the first obliquity sensor and the second obliquity sensor can detect tilting of automobile, and signal is sent to main control unit, main control unit can forbid that the spot turn device turns around.
The present invention makes main control unit can obtain the information of car running computer by the CAN bus communication module, when main control unit gets automobile and is in dead ship condition, can allow spot turn.
The left and right sides of automobile is provided with ultrasonic transduter, for detection of automobile both sides, whether pedestrian or vehicle is arranged, and guarantees the spot turn that carries out that automobile can safety.
Vehicle outer side is provided with several Warning lights, and the people around being used for reminding when spot turn notes dodging.

The specific embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is done in further detail and is introduced:
Structured flowchart of the present invention comprises as shown in Figure 1 for power circuit, main control unit, hydraulic pressure lifting apparatus 2, slewing arrangement 3, joystick, CAN bus communication module, the first obliquity sensor, the second obliquity sensor, A/D modular converter, the collecting sensor signal circuit of power supply and several ultrasonic transduters that are positioned at the vehicle right and left both sides; Described hydraulic pressure lifting apparatus 2 and slewing arrangement 3 are positioned at the center of bottom of car, are used for automobile is lifted and rotates to realize the function of spot turn; Described hydraulic pressure lifting apparatus 2 and slewing arrangement 3 are connected by data line with main control unit respectively, and main control unit is controlled hydraulic pressure lifting apparatus 2 and slewing arrangement 3 by the mode of communication; Described CAN bus communication module is connected by signal wire (SW) with main control unit, makes main control unit can obtain by the CAN bus communication module information of car running computer; Described the first obliquity sensor and the second obliquity sensor are connected with the signal input part of main control unit by the A/D modular converter respectively, for detection of the inclined degree of vehicle level direction; Described ultrasonic transduter is connected with the signal input part of main control unit by the collecting sensor signal circuit, for detection of motor vehicle environment whether have the pedestrian or object close; Described joystick is connected with the signal input part of main control unit, and the method for operation of described control lever is as follows: when joystick was pushed away forward, hydraulic pressure lifting apparatus 2 rose; When joystick was pulled back, hydraulic pressure lifting apparatus 2 descended; When joystick was pushed away left, slewing arrangement 3 rotated counterclockwise; When joystick was pushed away to the right, slewing arrangement 3 clockwise rotated; In the time of in the middle of control lever is moved to, hydraulic pressure lifting apparatus 2 and slewing arrangement 3 all stop action.Novel several Warning lights that also comprise the Warning light driving circuit and be positioned at vehicle outer side of this use; Described Warning light is connected with the signal output part of main control unit by the Warning light driving circuit, and main control unit is controlled the Warning light flicker and turned around with prompting vehicle by showing lamp drive circuit.
it is as follows that the car owner controls the process that automobile in-place turns around: at first, the car owner pushes away joystick forward, at this moment, the Warning light flicker, hydraulic pressure lifting apparatus 2 stretches out from the bottom of car body 1, and automobile is slowly pulled away ground 4(as shown in Figure 3), afterwards, the car owner with joystick left (or to the right) push away, make slewing arrangement cw (or conter clockwise) rotation (as shown in Figure 4), when vehicle rotary arrives the position of car owner's needs, the car owner pulls back joystick, at this moment, hydraulic pressure lifting apparatus 2 is slowly put back to automobile ground 4 and is recovered to the bottom of car body 1, Warning light extinguishes.In the whole process that automobile in-place turns around, main control unit can judge whether whether vehicle have people's (or object) near run-off the straight or vehicle by obliquity sensor and ultrasonic transduter, if the situation that vehicle run-off the straight or vehicle periphery have people's (or object) detected, main control unit will stop the work of hydraulic pressure lifting apparatus 2 and slewing arrangement 3, to guarantee safety.
