Abstract

The invention discloses a signal processing method and device, a vehicle and a storage medium. The signal processing method and device, the vehicle and the storage medium are applied to the vehicle. The vehicle comprises a safety belt, signal processing equipment and a first three-axis acceleration sensor. The signal processing equipment comprises a second three-axis acceleration sensor, and the signal processing equipment is arranged on the safety belt. When a user wears the safety belt, the signal processing equipment is located in front of the chest of the user, the first three-axis acceleration sensor is arranged in the vehicle, the distance between the first three-axis acceleration sensor and the user is larger than a preset distance, and the first three-axis acceleration sensor is connected with the signal processing equipment through a wire harness. The signal processing equipment is used for executing the signal processing method, and the signal processing method comprises thesteps that when the user wears the safety belt, user information is collected; and heart rate and respiratory rate are determied according to physiological signals of the user. The signal processing method and device, the vehicle and the storage medium are used for obtaining high-quality heart rate and respiratory rate for use.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of automobiles, and in particular, to a signal processing method, device, vehicle, and storage medium. Background technique [0002] As cars become people's daily means of transportation, high-frequency car usage makes users spend more and more time in cars. Car driving requires a high degree of concentration and good physical condition to ensure safe driving. Busy life makes more and more people in a sub-health state, and it is necessary to pay attention to multiple physiological parameters of the body in real time for disease prevention. However, most of the existing physiological signal collection devices are collected by wearing or short-term contact. , because of considerations such as comfort and portability, incomplete contact or too short contact time during the collection process leads to poor stability and accuracy of the collected physiological signals.
