Abstract

The invention discloses a heading angle calculation method, device, equipment and storage medium under parking working conditions, and belongs to the technical field of automatic parking. The present invention obtains the sensor information collected by the vehicle sensor under the parking condition, inputs the sensor information into a plurality of preset sub-models respectively, and obtains the reference heading angle output by each preset sub-model, and according to the output of each preset sub-model Determining the target heading angle with reference to the heading angle, using the target heading angle as the calculation result of the heading angle, by obtaining the reference heading angles output by multiple preset sub-models, and performing fusion calculation on the reference heading angles output by each preset sub-model, Obtaining the target heading angle makes the final calculated heading angle more accurate, and improves the accuracy of heading angle calculation under parking conditions.

Description

technical field [0001] The present invention relates to the technical field of automatic parking, in particular to a heading angle calculation method, device, equipment and storage medium under parking conditions. Background technique [0002] The heading angle refers to the angle formed by the vehicle's driving direction and the horizontal axis of the earth coordinate system under the earth coordinate system. The positioning of the heading angle in vehicle driving is a very important signal parameter, especially in low-speed driving conditions, under the low sensor and controller cost requirements, the vehicle's own sensors are used to calculate the body angle. In some working conditions For example, automatic parking can be applied well. Accurate body heading angle not only helps the driver to understand the current body posture in real time, but also provides accurate body heading for the automatic parking system path planning in the storage adjustment phase. angle to im...
