Abstract
The invention relates to a highway system with a vehicle position detection and telling device. Information such as the positions, the speed and the like of specific vehicles on the road surfaces can be detected in real time through various sensors arranged on the road surfaces, road sides or vehicles, and the relevant information of all vehicles are told to vehicles nearby in a broadcasting way after being gathered. On-vehicle computers of the vehicles can simulate vivid road conditions according to the information, and thus, drivers can drive safely in weather with insufficient visibility. Because various defects of detecting the road conditions by self equipment in the prior art are avoided, the fully practical full-automatic vehicle driving system becomes possible.
Description
Technical field
The present invention relates to the transport by road technology
Background technology
Traditional artificial or automatic vehicle drive mode, be to be the state that nearby vehicle is detected at the center with the vehicle, and then carry out driving operation as the foundation of driving, exist have tunnel vision, sight line is easily by limitations such as vehicle block, also do not influence driving because seeing the nearby vehicle situation at misty rain weather; For servomechanism, also exist some insoluble technology barriers such as vehicle identification, condition judgement, there is not ripe automated driving system so far.
Traditional highway has only satisfied basic driving condition, and the state of nearby vehicle can only be determined by visual by the driver.Various automated driving systems in the research all are the visuals field from vehicle self, survey the situation of nearby vehicle and make the driving decision-making with this.Because the visual field at first reaches the variation and the interference of vehicle mutual alignment, be difficult to monitor exactly the transport condition of nearby vehicle, cause automatic driving really to implement.
Summary of the invention
The present invention will be traditionally be the mode that peripheral state is surveyed at the center with the vehicle, change the state that the vehicle of system in travelling by road provides its other vehicles of periphery into.By the road vehicles sniffer reasonably is set, can detect position, the speed of all road vehicles in time, exactly, even information such as acceleration, deceleration and even break-in, with near the vehicle that travels informing by broadcast system after these information aggregation process, the latter with this as the foundation of driving.For automated driving system, these enough real-time information comprehensively and accurately guarantee safe driving fully, even can be more safe and reliable than pilot steering.
Because detection system is transferred to highway from vehicle, its visual angle, technological means, even cost etc. no longer is restricted, and can ideally realize the detection of vehicle-state.And for automated driving system, the real-time road condition information that provides according to Highway house, can judge the vehicle condition of periphery simply, and then draw best driving strategy, survey the mode of surrounding enviroment than relying on self fully, can reduce technical difficulty and system cost greatly, security performance also will greatly improve.
Traditional highway only provides basic vehicle handling capacity, descends at inclement weathers such as the rain of insufficient visibility, mists, and the driver can't carry out safe driving by range estimation.Use technology of the present invention, can not rely on the navigate VFR vehicle fully, thereby continue to keep the unimpeded of road.In addition, management organization can also carry out whole process monitoring in real time to all road vehicles, and for the vehicle of enforcements violating the regulations such as hypervelocity other device such as test the speed needn't be set can find at any time, does not have the blind area fully.
Except satisfying the demand of real-time automatic driving to information of vehicles, the information of vehicles of highway whole process can also be provided, be convenient to driver or aut.eq. and make judgement in advance, select best strategy.By the internet, can also provide real-time road condition inquiry to the public.
Embodiment
Under highway pavement, place the magnetic or the pressure transducer of sufficient amount at regular intervals, when vehicle by the time can the perception vehicle existence and transfer to the information of road surface disposal system.In fact, the technological means that detects vehicle location has multiple, such as, by vehicle-mounted satellite positioning device, also can obtain the status information such as position of particular vehicle and offer highway system.After this system gathers the information of vehicles of collecting, mode by regional broadcast again, the information of vehicles in a certain zone is broadcast to the vehicle of this zone in travelling, the vehicle-mounted computer system of these vehicles can be drawn out the real-time scene image of self and nearby vehicle in view of the above, even if the misty rain weather of insufficient visibility, the driver only can carry out safe driving to vehicle according to these images.And,, then can select safe and reliable driving strategy simply as long as control safe distance with nearby vehicle well for automated driving system, not needing fully to realize manual intervention, automatic driving truly, the revolution that finally brings drive manner.
Similarly, had in real time, comprehensive traffic information, vehicle operating monitoring etc. has also been become ery easy, can in time find the various behaviors and make disposal of driving against traffic regulations.
Claims (8)
1. one kind has that vehicle location detects and the highway system of informing device, it is characterized in that, the status detection devices such as can detecting road vehicles position, speed that distributing in the length range of highway can detect the various running statuses of whole road vehicles in real time by these devices.
2. vehicle detection apparatus according to claim 1, it is characterized in that, can be pressure or the magnetic detector that is embedded under the road surface, also can be arranged on optics, radio or the ultrasonic positioner of both sides of highway, also can be the pick-up unit of vehicle and road surface interaction, also can be satellite positioning device or other the various relevant apparatus that can determine states such as vehicle location, speed effectively that are installed on the vehicle.
3. pick-up unit according to claim 1 is characterized in that, system can also detecting pedestrian, all and the relevant information of driving a vehicle such as road conditions, barrier except detecting road vehicles information.
4. pick-up unit according to claim 1, it is characterized in that, road vehicles can be by " electronic tag " self installed, inform to pick-up unit by radiowave and oneself identifying informations such as the number-plate number total system can be linked together car plate-vehicle model-relevant informations such as travel condition of vehicle.
5. according to the description of claim 2, these pick-up units towards be the vehicle of whole road vehicles rather than ad-hoc location or kind, its quantity and layout should cover whole road surfaces, do not have the dead angle surveyed, and satisfy requirements such as real-time, accurate.
6. one kind has that vehicle location detects and the highway system of informing device, it is characterized in that, after information such as the detected road vehicles of system are gathered and are handled, data layout with certain agreement, by near the radio device that is provided with at interval on the highway or the highway, road vehicles near zone is broadcasted in real time, and the time interval of broadcasting should be enough little, to satisfy the demand of driving process road pavement vehicle real-time status data.
7. according to claim 6, the information such as road vehicles that system detects can provide to all vehicles or particular vehicle selectively, can also provide details and omissions different information according to the distance of distance, as near the information the vehicle should be more detailed and real-time, such as the profile that comprises near vehicle, speed, direction etc., then can only provide information at a slow speed such as position, road vehicles density for vehicle than a distant place.
8. according to claim 6, information of vehicles can be broadcasted with existing information stack such as road-map back vehicle in the zone, is convenient to traffic navigation.
