The invention discloses a carpooling system and method for matching information through a route segmenting method. The carpooling system comprises a mobile passenger terminal, a mobile driver terminal, a website platform, a car hire managing and dispatching system and a communication module, wherein the mobile passenger terminal, the mobile driver terminal, the website platform and the car hire managing and dispatching system communicate with one another through the communication module. Based on a common computing and matching method, in order to achieve matching of same-direction carpool information to the maximum extent, a vehicle route is matched by adopting a full-route coordinate segmenting way to help a passenger to match the optimal route and the predicted arrival time of a vehicle going in the same direction. The carpooling system is applied to a mobile terminal product and an Internet platform, and has a greater same-direction carpooling matching range, more optimized matching accuracy and zero error rate, thereby directly improving the carpooling matching success rate; the carpooling system has the characteristics of energy conservation, low carbon and environment friendliness, simultaneously reduces the pressure of public transport, and relieves traffic congestion to a certain extent.
