Abstract
The utility model discloses a single-chip microprocessor-based parking assist device, which comprises a single-chip microprocessor, wherein an input end of the single-chip microprocessor is connected with a laser radar sensor, a steering angle sensor and a speed sensor through an A/D (Analog/Digital) converter respectively; and an output end of the single-chip microprocessor is connected with a voice prompt module and a display screen respectively, and is also connected with a steering mechanism and a braking mechanism through a parking control switch. According to the device, an active and passive combined mode is adopted; and when a proper parking space is detected, a driver can perform original active parking operation, and meanwhile, the driver can also press down the automatic parking control switch, so that the vehicle automatically controls the work of the steering mechanism and the braking mechanism according to a parking route designed by the single-chip microprocessor on the basis of the acquired information in advance and can get into the parking space according to the correct route.
Description
Technical field
The utility model belongs to self-propelled vehicle safe driving field, is specifically related to a kind of SCM Based parking assist apparatus.
Background technology
Along with the fast development of automotive technology, the popularity rate of automobile is more and more higher, and the problem of bringing simultaneously is that the parking stall demand is increasing, and the space on parking stall is more and more littler, thereby more and more feels the problem of " parking difficulty " in modern metropolitan cities.Move backward into bit manipulation in narrow space, concerning a lot of motorists, be difficult to once pour car into parking stall smoothly.The traffic accident that causes is thus also increasing year by year, and accounts for a big chunk in the traffic accident.Though seldom can cause serious traffic accident in the reversing accident, bring a lot of troubles through regular meeting to the car owner, as knock others car, fire hydrant or other obstacles and so on, if bump against pedestrian on the road, that consequence is hardly imaginable especially.Along with development of technology, increasing parking assistance system has obtained application.This paper has proposed a kind of novel automatic parking auxiliary device at existing problem.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model is, a kind of SCM Based parking assist apparatus is provided.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
A kind of SCM Based parking assist apparatus comprises micro controller system, and the input end of micro controller system links to each other with laser radar sensor, steering angle sensor and speed sensor respectively by A/D converter; The mouth of micro controller system links to each other with read-out with voice cue module respectively, and the mouth of micro controller system also links to each other with stop mechanism with steering hardware by the master cock of parking.
The utility model also has following technical characterstic:
Described micro controller system adopts the S12 micro controller system.
Described laser radar sensor adopts the SICK laser radar sensor; Described speed sensor adopts the Hall-type speed sensor; Described steering angle sensor adopts the magneto-electric rotary angle transmitter.
Described voice cue module adopts the YT07-JD speech chip.
The utility model has adopted initiatively and the passive mode that combines, when detecting suitable parking stall, chaufeur can carry out the original active operation of parking, simultaneously also can press the automatic parking master cock, at this moment vehicle will be controlled the work of steering hardware and stop mechanism automatically according to the parking route that micro controller system design in advance according to the information that collects, make the vehicle can be according to the parking stall of driving into of correct line.
Description of drawings
Fig. 1 is annexation scheme drawing of the present utility model.
Below in conjunction with drawings and Examples particular content of the present utility model is done explanation in further detail.
The specific embodiment
Below provide specific embodiment of the utility model, need to prove that the utility model is not limited to following specific embodiment, all equivalents of doing on present techniques scheme basis all fall into protection domain of the present utility model.
Defer to technique scheme, as shown in Figure 1, a kind of SCM Based parking assist apparatus comprises micro controller system, and the input end of micro controller system links to each other with laser radar sensor, steering angle sensor and speed sensor respectively by A/D converter; The mouth of micro controller system links to each other with read-out with voice cue module respectively, and the mouth of micro controller system also links to each other with stop mechanism with steering hardware by the master cock of parking.
Described laser radar sensor adopts the SICK laser radar sensor of German import, is installed in the outer periphery of vehicle, and every side is installed two, is used for parking stall information around the collection vehicle and the distance of the process middle distance obstacle of parking.
Described tachogen is magnetoelectric tachometric transducer, and tachogen is installed on the camshaft of driving engine, is used for gathering current tach signal.
Described steering angle sensor adopts the magneto-electric rotary angle transmitter, and steering angle sensor is installed on the turning cylinder of bearing circle, is used for gathering current steering angle signal.
Described voice cue module is installed in the operator's compartment, is used for pointing out chaufeur to detect suitable parking stall, can carry out shut-down operation.
Described read-out adopts the TCL read-out, is installed in the operator's compartment, is used for showing information and the current position of vehicle body on parking stall.
Described micro controller system adopts the S12 micro controller system.Micro controller system is gathered in real time and is come from laser radar sensor, speed sensor and steering angle sensor signal, the control policy that foundation is certain, algorithm are to the incoming signal calculation process, if when detecting suitable parking stall, to calculate a rational parking route, and carve when appropriate and provide control signal.Control signal makes vehicle according to predetermined parking route running by automatic parking master cock control steering hardware and stop mechanism.Read out instrument is used for showing information and the position of vehicle body in the parking stall on real-time parking stall.
Concrete work engineering of the present utility model is as follows: when chaufeur need stop, start the utility model, this moment, laser radar sensor will be gathered obstacle information on every side, micro controller system calculates by certain algorithm by the obstacle information that collects does not have suitable parking stall, when satisfactory parking stall, the graphicinformation on parking stall will be passed to read-out, and find suitable parking stall by voice cue module prompting chaufeur, can carry out shut-down operation.Micro controller system has also calculated a rational parking route according to certain control policy and algorithm simultaneously.At this moment chaufeur can carry out shut-down operation according to purpose operation brake pedal and the bearing circle of oneself, and chaufeur also can be pressed the master cock of parking and carries out automatic parking in addition.When carrying out automatic parking, micro controller system goes out the needed rational speed of a motor vehicle and steering wheel angle according to predefined route calculation, control stop mechanism and steering hardware with this, while speed sensor and steering angle sensor be speed and the steering wheel angle of collection vehicle timely, when the speed of reality and deflection angle depart from predetermined value, micro controller system will be revised in time, so that vehicle travels according to precomputing the path of coming, until last parking.
