Abstract: Provided are a method, an apparatus and a device for obstacle in lane warning. The method includes receiving information of an obstacle in a front lane of a first vehicle, where the first vehicle is in front of a second vehicle; and performing an obstacle warning on the second vehicle according to the information of the obstacle. The second vehicle receives the information of the obstacle, and performs the obstacle warning on the second vehicle according to the information of the obstacle to prevent the second vehicle from failing to detect the obstacle in a blind area when the sight of the second vehicle is blocked by the first vehicle; the front vehicle notifies the subsequent vehicle of the obstacle in the lane immediately, which facilitates the driver to handle the situation in advance, improves the vehicle's ability to sense the obstacle and prevents the collision from occurring.

Abstract: Provided are a vehicle positioning method, an apparatus and a device. The method includes: sending an auxiliary positioning request to an auxiliary positioning device within a preset distance range; receiving an auxiliary positioning message returned by the auxiliary positioning device with respect to the auxiliary positioning request, where the auxiliary positioning message carries location information of the auxiliary positioning device; and determining a current location of a current vehicle according to the location information of the auxiliary positioning device and distance information between the current vehicle and the auxiliary positioning device. The method of the present disclosure can implement vehicle positioning without a satellite positioning signal. The vehicle positioning can be performed when the vehicle is blocked by an obstacle such as a tunnel, a building and the satellite positioning signal cannot be received, improving the accuracy of the vehicle positioning.
