Fig. 5 represents the system architecture of smart mobile phone 10.On mobile phone hardware 12 (comprising the various modules among Fig. 3), it is operation system of smart phone 40, be various onboard system application software 50 on operating system 40, comprise valuation software 51, dispatcher software 52, monitoring software 53, authentication software 54, ad ware 55, remote service software 56 etc.Wherein, valuation software 51 utilizes real-time positioning information to calculate fare, and it can substitute traditional fee register; Dispatcher software 52 is by reporting vehicle information (such as the position etc.), obtains next bit passenger's information (such as the position etc.) from the backstage; Monitoring software 53 monitoring cab driving situation and passenger's situations, protection driver and passenger safety; Whether authentication software 54 these commerial vehicles of checking are legal, hit clone's car; Ad ware 55 is play advertisement or other advertisement near its destination to the passenger targeted specifically; Remote service software 56 provides the functions such as software upgrading for smart mobile phone, makes things convenient for function upgrading and expansion.
Because smart mobile phone can be vehicle location at any time by GPS, it can be as the fee register of taxi.Traditional taxi adopts following pricing method: when the speed of a motor vehicle greater than pre-set velocity (such as 10 kilometers/hour), valuate with mileage; When the speed of a motor vehicle less than pre-set velocity, valuate with the time.Because the bearing accuracy of GPS is far longer than traditional mileometer, adopt the fee register of GPS to have better mileage accuracy.Fig. 6 A represents a kind of valuation process flow diagram of the software 51 of valuating.Begin (step 101) after the valuation, the information calculations speed of a motor vehicle that provides according to locating module 34 is if the speed of a motor vehicle is greater than pre-set velocity (step 103), with mileage valuation (step 105); Otherwise with time valuation (step 106).Repeat these steps, until arrive destination (step 107).
The GPS of consumer level does not generally have the ability by the direct reading speed of Doppler effect, and its speed is that (this mistiming is self sample interval t of GPS, t's～1s) obtain divided by the corresponding mistiming for displacement by continuous two outputs of GPS.Because GSP location generally has～and 10 meters error, if vehicle is comparatively approaching in the position of these two output time points, then the error of speed calculating is larger.This be GPS to low speed (＜30 kilometers/hour) reason that measuring error is larger, and this error is along with Speed Reduction can become larger.
The pre-set velocity of tradition fee register is 10 kilometers/hour (i.e. 2.8 meter per seconds).As adopt self sample interval t=1s of GPS, then the displacement within this time interval is 2.8 meters.For the GPS of site error～10 meter, its velocity error can be very large.Therefore, adopt conventional GPS rate algorithm to calculate fare and produce larger error.The present invention has improved the rate algorithm of valuation software, the degree of accuracy of calculating to improve fare.
The present invention does not adopt self sample interval t of GPS when computing velocity, but adopts longer sample interval (the first sample interval T).Because the time interval is elongated, displacement strengthens, and then velocity error can reduce a lot.For example, for 10 kilometers/hour, such as T=1 minute, then displacement was 160 meters, and for the GPS of site error～10 meter, velocity error is less.Fig. 6 B has represented to take the valuation flow process of this method.This valuation flow process is calculated in the first sample interval T the information (being herein displacement) (step 102) with velocity correlation.If this displacement is then valuated with mileage greater than preset displacement (such as 1 minute displacement greater than 160 meters); Otherwise valuate with the time.When calculating mileage, can calculate the information (herein as displacement) relevant with mileage take the second sample interval T '.For fear of few calculation mileage, T ' generally adopts self sample interval t; In order to reduce operand, T ' also can be under the prerequisite that does not reduce precision, and is slightly larger than t.In general, T＞T ' 〉=t.
