Description

The control method of a kind of electric automobile safety traffic and safety electric electrical automobile
Technical field
The present invention relates to a kind of electric automobile, particularly to the control method and the safety that are the safety traffic of a kind of electric automobile Type electric automobile.
Background technology
Being limited to the pressure of environment and resource, the development of electric automobile is by most attention both domestic and external.Electric automobile is only capable of Utilizing the battery as the source providing electric energy, once the electric energy of battery exhausts, and electric automobile also will stop and cannot continue Advance.
Flourish along with electric automobile, electric automobile charging station network the most day by day start development, but working as Under precondition, it still can not the same with gas station spread all over the world.Although charging station network is becoming better and approaching perfection day by day, but general due to charging station And degree is not, still needs to car owner during driving and judge following two problem voluntarily: whether location is not more than surplus with the distance of destination The distance travelled that remaining electricity can be done by, or charging station halfway can be arrived before electricity consume be charged.
Before charging station is not popularized as gas station, most human pilot can fear the electric energy meeting that battery can be provided by The most suddenly using up, this idea also counteracts that the sales situation of electric automobile.
And if when electric automobile the most particularly travels on expressway, if as battery-depletion, caused Electric automobile stops suddenly, it is easy to cause the vehicle accident knocked into the back.
In view of problem and the defect thereof of above-mentioned existence, how to develop the control method of a kind of electric automobile safety traffic, Become practitioner in the art urgently to want to solve the technical problem that.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides the control method of a kind of electric automobile safety traffic Including: step one, battery monitoring unit detects current battery charge surplus value in real time, when battery electric quantity surplus value sets less than first During definite value, persistently detect the speed of current power automobile;Step 2, starts navigation positioning unit and alerts, and according to battery Electricity surplus value is planned automatically from the charging station that my car is nearest;Step 3, when navigation positioning unit remains according to current battery charge Residual value and current location judge that battery electric quantity surplus value is not enough to support electric automobile when reaching nearest charging station, electric automobile Enter safety traffic pattern, persistently monitor the spacing between electric automobile back car and my car now by navigation positioning unit And the speed of front vehicle;Step 4, when the spacing of my car and back car is less than the first distance, the speed comparing two cars is big Little, when the speed of my car is less than the speed of back car, control unit for vehicle automatically turns on the hazard warning lamp of vehicle To alert back car;Step 5, the position of the nearest parking site of navigation positioning unit self-navigation, and it is pushed to driver.
For further mature technology scheme, present invention additionally comprises techniques below feature:
As improving further, described first setting value is 30 the percent of all batteries electricity.
As improving further, described first distance is 100 meters.
As improving further, when battery electric quantity surplus value is less than the 10 of all batteries electricity, navigator fix Unit starts to monitor whether front road conditions have climbing section and be pushed to driver.
As improving further, described control unit for vehicle controls vehicle and enters energy saver mode.
As improving further, when vehicle is in energy saver mode, control unit for vehicle closes room light unit and sound Ring unit.
The present invention separately provides a kind of safety electric electrical automobile to include: battery monitoring unit, control unit for vehicle and navigation are fixed Bit location, described battery monitoring unit is in order in real time detection current battery charge surplus value, when battery electric quantity surplus value is less than the During one setting value, described navigation positioning unit is according to when battery electric quantity surplus value real-time positioning and revise the nearest of direction of traffic Charging station, when according to current battery charge surplus value and current location, navigation positioning unit judges that battery electric quantity surplus value is not enough When reaching nearest charging station with support electric automobile, navigation positioning unit persistently monitors between electric automobile back car and my car Spacing and the speed of front vehicle;When the spacing of my car and back car is less than the first distance (100 meters), compare two cars Speed size, when the speed of my car is less than the speed of back car, control unit for vehicle automatically turns on the danger warning of vehicle Flash lamp is to alert back car.
As improving further, described electric automobile is pure electric automobile.
To sum up, the present invention at least includes techniques below effect:
1, the present invention passes through battery monitoring unit, control unit for vehicle and the cooperation of navigation positioning unit three, works as battery cell monitoring Unit monitors to battery electric quantity surplus value less than the first setting value (30 the percent of all batteries electricity) time, then by navigation Positioning unit carries out alarm and automatically plan can be with the charging station route of quick charge, and on the road leaving for charging station, and battery Monitoring unit also can persistently monitor battery electric quantity and monitored results is informed navigation positioning unit, when navigation positioning unit is through undue Analysis finds that dump energy is not enough to support electric automobile when reaching nearest charging station, then can by control unit for vehicle automatically into Safety traffic pattern, now by navigation positioning unit persistently monitor the spacing between electric automobile back car and my car and after The speed of side's vehicle;When the spacing of my car and back car is less than the first distance, compare the speed size of two cars, when my car When speed is less than the speed of back car, control unit for vehicle automatically turns on the hazard warning lamp of vehicle to be come with alarm rear Car;The position of the nearest parking site of navigation positioning unit self-navigation simultaneously, and it is pushed to driver.Thereby, the present invention is driven Electric automobile electric automobile can be avoided the most not arrive at before running down of battery, it is impossible to the situation of action.And also may be used The vehicle all standing occurred due to dead battery capability during to prevent electric automobile during traveling on the way, advance notice front vehicle, with Exempt to cause the problem of knocking into the back.
2, when the electric automobile of the present invention enters safety traffic pattern, control unit for vehicle controls vehicle and enters energy-conservation mould Formula, now closes room light unit and acoustics unit etc. and travels unrelated unit with vehicle, with by battery electric quantity substantially Utilize on vehicle travels, and when battery electric quantity surplus value is less than the 10 of all batteries electricity, navigation positioning unit Start to monitor whether front road conditions have climbing section and be pushed to driver, it is to avoid vehicle travels when climbing section at battery electricity There is Landslide Problems when exhausting in amount.
