The solution is applicable to the technical field of data processing, and provides a vehicle positioning method and device and a terminal apparatus. The method comprises: if the strength of a satellite-based positioning signal is less than a strength threshold, reading the number of bus stops within a preset range of a vehicle and determining whether the number is greater than a number threshold; and if the number of bus stops is greater than the number threshold, reading location information of the bus stops and receiving wireless positioning signals sent by the bus stops, and calculating location information of the vehicle on the basis of the location information of the bus stops and the wireless positioning signals; or if the number of bus stops is less than or equal to the number threshold, reading the previous positioning time and position information of the previous positioning of the vehicle, and calculating position information of the vehicle on the basis of the position information of the previous positioning and a position offset. Embodiments of this solution perform situational subdivision in situations where satellite-based positioning signals are relatively weak, and provide multiple corresponding methods for performing accurate positioning, thereby performing accurate positioning on a vehicle even when satellite-based positioning signals are relatively weak.
