Abstract

The invention discloses a vehicle somatosensory evaluation method and device, electronic equipment and a storage medium, and relates to the technical field of unmanned driving. According to the specific scheme, in the running process of a vehicle, the pressure of a measured object acting on all measurement areas of a target carrying device under the current weight is measured through at least onepressure sensing unit within a measurement time period; according to the pressure, measured by each pressure sensing unit, of each measurement area and the individual size of each pressure sensing unit, the pressure intensity generated by the pressure, acting on each measurement area, of the measured object is calculated; an objective somatosensory evaluation score of the measured object under thecurrent weight is determined according to each measured pressure and each calculated pressure; and a comprehensive somatosensory evaluation score is calculated according to the objective somatosensory evaluation score and a predetermined subjective somatosensory evaluation score. According to the embodiment of the invention, the accuracy of somatosensory evaluation can be improved, the one-sidedness of subjective evaluation is reduced, and meanwhile, the quantitative result of somatosensory measurement can be obtained.

Description

technical field [0001] The present application relates to the field of artificial intelligence, and further relates to the field of unmanned driving technology, especially a vehicle somatosensory evaluation method, device, electronic equipment and storage medium. Background technique [0002] A self-driving vehicle is a kind of intelligent vehicle, which can also be called a wheeled mobile robot. It mainly relies on the computer system-based intelligent driver in the vehicle to realize unmanned driving. One goal of self-driving vehicles is to give passengers a better sense of body while riding. During the development and testing of autonomous driving, it is necessary to frequently evaluate the feelings of passengers in the driving process of the vehicle, so as to verify whether the planning of the vehicle needs to be improved. Therefore, the effectiveness and efficiency of somatosensory evaluation are crucial to the development of unmanned driving. [0003] At present, the...
