针对目前出租车计价器在计时和计程方面存在的问题,提出了利用GNSS+INS+Odometer组合导航技术进行出租车计价的方法。运用组合导航技术对出租车载客过程中里程和时间进行计算,一方面可以避免传统计价器在使用过程中由于计价器本身以及人为因素等原因,改变实际的行驶里程,影响计价的准确性,从而提高计价的准确性;另一方面,可以避免单一的里程计计价过程中一旦出现故障,里程结果出现较大误差或无法计价等情况,增加出租车计价系统的可靠性。通过跑车试验证明:将组合导航技术应用于出租车计价系统中,能够对出租车计程、计时以及低速计价等关键问题作出很大改进,在计价的精度和可靠性方面都有显著提高;避免因计价器不准等原因造成的乘客、出租车司机之间的矛盾,维护双方的合法权益;对组合导航技术的发展起到了很好的推动作用。
Aiming at the problem of taxi meter in terms of timekeeping and taxiing, a method of taxi pricing using GNSS + INS + Odometer integrated navigation technology is proposed. The use of integrated navigation technology to calculate the mileage and time of taxi carrying passengers on the one hand to avoid the traditional meter in the course of the use of the meter itself and human factors and other reasons to change the actual mileage and affect the accuracy of pricing, So as to improve the accuracy of the pricing. On the other hand, it is possible to avoid the situation that a single odometer in the pricing process fails, the mileage results in a large error or can not be priced, and the reliability of the taxi pricing system is increased. The test of sports car proves that applying the integrated navigation technology to the taxi pricing system can greatly improve the key problems such as taxi scheduling, time counting and low-speed pricing, and improve the accuracy and reliability of the pricing remarkably. Avoid The conflict between the passengers and taxi drivers caused by the failure of the meter and other reasons to safeguard the legitimate rights and interests of both parties and play a good role in promoting the development of the integrated navigation technology.
