The present invention relates to intelligent vehicle double steering engine 4 wheel driven to turn to and automatic control technology field, the dolly of particularly a kind of double steering engine four-wheel drive omnidirectional ultrasonic detection.
Background technology
At present, the steering technique of intelligent vehicle is generally that single steering engine two-wheel drive turns to, and single steering engine two-wheeled turns to the space of needs large, underaction and the maneuverability shortcoming such as comparatively.And four steering wheel four-wheel steering technology are not yet ripe, and there is the shortcomings such as complex structure and algorithm be complicated and can not fully be applied on vehicle.Intelligent carriage is by various sensing system sensing external environment and oneself state, and autonomous in the known of complexity or circumstances not known also completes response task.Adopt multisensor pattern can avoid detecting dead angle.Therefore obstacle avoidance apparatus becomes the equipment of intelligent carriage indispensability.
Summary of the invention
Technical matters to be solved by this invention is for defect involved in background technology, provides the dolly that a kind of double steering engine four-wheel drive omnidirectional ultrasonic detects.
The present invention is for solving the problems of the technologies described above by the following technical solutions:
A dolly for double steering engine four-wheel drive omnidirectional ultrasonic detection, comprises two front-wheels, two trailing wheels, four motors, two steering wheels, four ultrasonic sensors, central data processing module and supports;
Described support is used for fixing four wheels, four motors, two steering wheels, four ultrasonic sensors and central data processing modules;
Described four motors respectively with two front-wheels, two trailing wheels connect one to one, for providing the driving force of vehicle wheel rotation;
One in described two steering wheels for controlling the direct of travel of two front-wheels, another is for controlling the direct of travel of two trailing wheels;
Two in described four ultrasonic sensors both sides being separately positioned on described support, for responding to the barrier of dolly both sides; Two other is separately positioned on two steering wheels, for responding to the barrier on dolly two front-wheel direct of travels and on two trailing wheel direct of travels;
Described central processing module respectively with four motors, two steering wheels, four ultrasonic sensors are electrically connected, for according to induction output control four motors of four ultrasonic sensors and two steering wheel work.
As the further prioritization scheme of dolly of a kind of double steering engine of the present invention four-wheel drive omnidirectional ultrasonic detection, described motor is direct current deceleration motor.
As the further prioritization scheme of dolly of a kind of double steering engine of the present invention four-wheel drive omnidirectional ultrasonic detection, described central data processing module adopts Arduino single-chip microcomputer.
As the further prioritization scheme of dolly of a kind of double steering engine of the present invention four-wheel drive omnidirectional ultrasonic detection, the model of described Arduino single-chip microcomputer is Arduino Mega 2560.
The present invention adopts ultrasonic sensor as the location of barrier and measuring element, and it has highly sensitive, and take measurement of an angle large, antijamming capability is strong, not by advantages such as the external environments such as sunshine affect, is more suitable for outdoor use.
Central data processing module adopts Arduino single-chip microcomputer as processor, and it is low in energy consumption, and operating temperature range is wide, stable performance.
When two steering wheels turn to and angle is identical, diagonal can be realized; When two steering wheels turn to contrary, radius of turn during low speed driving can be reduced largely, be convenient to narrow road surface and carry out U-shaped turning.
The present invention adopts above technical scheme compared with prior art, has following technique effect:
