Abstract

The invention discloses a course angle calculation method, device and equipment under a parking working condition and a storage medium, and belongs to the technical field of automatic parking. In theinvention, the method is characterized by acquiring sensor information collected by a vehicle sensor under a parking working condition; inputting the sensor information into a plurality of preset sub-models, obtaining a reference course angle output by each preset sub-model; determining a target course angle according to the reference course angle output by each preset sub-model, and taking a target course angle as a course angle calculation result; and obtaining the target course angle by obtaining reference course angles output by the plurality of preset sub-models and performing fusion calculation on the reference course angles output by the preset sub-models. Therefore, the finally calculated course angle is more accurate, and accuracy of course angle calculation under the parking working condition is improved.

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...
