Description
Technical field
This utility model relates to field of automobile, is specifically related to a kind of Speed Limitation on Freeway cruise system based on satellite fix.
Background technology
Cruise Control System can make automotive service exactly in the favourable range of speeds of electromotor, alleviates the riding manipulation labor intensity of driver, improves the automobile automatic running device of driving comfort.
In the country of continent type, the chance of the long-distance running that drives a car is more, and travel on a highway time-varying change trains the frequency of speed and scope the most less, relatively can travel with stable speed.If but drive over a long distance and right crus of diaphragm have to accelerator pedal time, long foot is easy for feeling tired, causes driver's energy not concentrated, there is potential safety hazard.After the effect of Cruise Control System is exactly the speed Guan Bi switch as required by driver, just can automatically keep speed without accelerator pedal, make vehicle travel with fixing speed.Have employed this device, after driving a vehicle for a long time on a highway, driver just need not go to control gas pedal again, alleviates fatigue, decreases unnecessary speed change simultaneously, can save fuel.
Recently, due to high-speed secure Frequent Accidents, traffic law is more and more stricter for the punishment of hypervelocity at a high speed.And China has again different speed limits to specify for different high-speed road conditions, such as tunnel, tunnel group speed limit are generally according to 80 kilometers/hour, accident-prone road section speed limit is generally below main line 20 kilometers/hour at a high speed, and driver is likely due to the reasons such as carelessness and exceeds the speed limit.Additionally, vehicle can not operate under general cruise mode always, cruise mode does not has real realization cruise.
Utility model content
For solving the deficiency that prior art exists, the utility model discloses Speed Limitation on Freeway cruise system based on satellite fix and cruise method, this system start when vehicle launch to receive from the vehicle location information of satellite, all the time by current vehicle speed compared with the speed limit in front, relevant position certain distance in data base (in generally 500 meters), if judging, there is speed limit requirement in front, then vehicle is decelerated to the 90% of regulation speed voluntarily, speed-down action is done without driver, the economic loss brought because of hypervelocity is it also avoid while the speed that ensures safety, also eliminate the cost installing driving safety early-warning apparatus (being commonly called as " cyberdog ") simultaneously.
For achieving the above object, concrete scheme of the present utility model is as follows:

Further, described car load module includes power assembly system and brakes, power assembly system receives the instruction from CAN, adjusts electromotor and carries out corresponding action, and brakes accepts to be braked action or attonity from the control signal of signal processing module.
Further, the throttle position of vehicle, gear information, automobile's instant velocity and instantaneous fuel consumption information are inputed to signal processing module as status feedback signal by described car load module；Described status feedback signal is using as the correction adjusting control signal.
Further, described power assembly system includes engine management system and transmission system, both are receiving after the control signal of CAN, the ECU of engine management system is according to signal instruction and coordinates transmission system, in conjunction with vehicle current vehicle speed, the distributive value of oil consumption status information adjustment electromotor, fuel supply advance angle information, makes power assembly meet requirement.
Further, described display module is incorporated on the instrumental panel of car load, is a LED, the most whether vehicle is in cruising condition intuitively on instrumental panel.
Further, when described vehicle enters cruise mode, make speed be less than high limiting speed of driving speed data by unlocking vehicle brakes, and reduce engine oil amount and reduce gear, make output speed and vehicle rotational speed matches.
The cruise method of a kind of high-speed road conditions speed limit cruise system based on satellite fix, comprises the following steps:
Step (1): press " ON/OFF " button being positioned on steering wheel during vehicle launch, inputs to satellite positioning module and signal acquisition process module by the request signal that cruise system is opened；
Step (2): the throttle position signal of signal acquisition process module record current power assembly system offer and gear signal, and this signal is persistently inputed to as control signal car load module；
Step (3): vehicle enters cruise mode, signal acquisition process module starts lasting collection vehicle position signalling, current automobile's instant velocity is contrasted with the high limiting speed of driving speed data in current vehicle position front setpoint distance in data base, if less than this value, then vehicle keeps existing speed continuous service；If greater than this value, then make speed be less than high limiting speed of driving speed data by unlocking vehicle brakes, and reduce engine oil amount and reduce gear, make output speed and vehicle rotational speed matches；
Step (4): when again pressing " ON/OFF " button being positioned on steering wheel, stopping signal passes to signal acquisition process module and satellite positioning module, and vehicle enters driver pattern.
Further, if vehicle is in running, press " acceleration " button on steering wheel, the request signal accelerated then is input to signal acquisition process module, this module is according to request signal, by increasing fuel delivery and improving gear, and the status feedback signal combining integration module return is adjusted, and makes speed stable in target location.
Further, if vehicle is in running, driver wants to reduce the cruise speed of vehicle, press " deceleration " button on steering wheel, the request signal slowed down then is input to signal acquisition process module, and this module, according to request signal, reduces fuel delivery and reduction, and the status feedback signal combining integration module return is adjusted, make speed stable in target location.
The beneficial effects of the utility model:
This utility model can realize vehicle when travelling on a highway, open cruise mode, and detect front and the need of speed limit and automatically speed is dropped to limit value 90%, vehicle can be reduced in the problem running into front speed limit and frequently switch cruise mode, also being effectively reduced driver's long period drives the fatigue driving and safety problem brought, and it also avoid the economic loss brought because of hypervelocity while the speed that ensures safety.Vehicle automatically controls distributive value and uniform speed during cruise, it is ensured that the dynamic property of vehicle and economy.
