Embodiment Construction

[0049] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0050] GNSS can be a multi-mode satellite positioning module based on the global satellite positioning system, Russia's GLONASS navigation system, EU's Galileo navigation system, China's Beidou second-generation navigation system and satellite-based augmentation system.

[0051] Such as figure 2 As shown, in the prior art, the method for the vehicle-mounted system to obtain the GNSS positioning signal is as follows:

[0052] After the GNSS positioning hardware module is powered on, under the condition that the satellite signal can be received normally, it will carry out signal acquisition, tracking, positioning, speed measurement, and timing, and the data such as position, speed, satellite status, and time will be transmitted in ...

Abstract

An embodiment of the present invention provides a vehicle positioning method, device, vehicle, and computer-readable storage medium. The method includes: acquiring abnormality determination information of an on-vehicle system on the vehicle; determining whether the abnormality determination information satisfies a preset positioning abnormality Conditions; if the abnormality determination information satisfies the preset positioning abnormality condition, it is determined that the positioning is abnormal; performing a positioning abnormality recovery operation; outputting the positioning information after the recovery operation is completed. In the embodiment of the present invention, by acquiring abnormality determination information and judging whether the abnormality determination information satisfies a preset condition, it is determined whether the positioning is abnormal; and performing a positioning abnormality recovery operation, and outputting the positioning information after the recovery operation is completed. Therefore, it can be accurately determined whether an abnormality occurs in the positioning, and the abnormal positioning can be quickly corrected to reduce the probability of navigation errors.

Description

technical field [0001] The present invention relates to the technical field of positioning, in particular to a vehicle positioning method, a vehicle positioning device, a vehicle and a computer-readable storage medium. Background technique [0002] Normally, such as figure 1 As shown, the positioning of the smart car is mainly through the collection of satellite positioning data sent by GNSS (Global Navigation Satellite System, Global Navigation Satellite System), vehicle speed signals, and sensor data such as gyroscopes and accelerometers. positioning information, and then match the calculated positioning information with map data to obtain accurate location information. [0003] However, due to the inability of GNSS to receive positioning signals (signal occlusion or weak signals, etc.), or the clock problem of the hardware itself, it is easy to cause positioning abnormalities. Fix abnormal positioning information. Contents of the invention [0004] In view of the abo...
