Abstract

The invention discloses a sensing system, a measuring method, a detecting system including the sensing system and a traffic tool. The sensing system comprises a magnetic resistive (MR) sensor unit (101), a first path (111) and a processing unit (109), wherein the MR sensor unit is used for sensing a magnetic field associated with a to-be-measured object, and the MR sensor unit comprises an MR element; the first path is used for receiving a first electric signal including noise voltage from the MR sensor unit and generating a first digital signal corresponding to the noise voltage; and the processing unit is configured for determining the noise power spectral density according to the first digital signal and determining the temperature of the to-be-measured object according to the determined noise power spectral density and a resistance value of the MR sensor unit, wherein the first electrical signal is voltage at the two ends of the MR sensor unit.

Description

technical field [0001] The present disclosure relates to a sensing system, a measurement method, a detection system including a sensing system, and a vehicle, and more specifically, relates to a sensing system that can realize one or more functions, such as measuring the temperature and current of an object and methods of rotation speed, etc., and a detection system and a vehicle including the sensing system. Background technique [0002] Energy storage systems and traction systems are key components of electric vehicles (EVs), such as electric vehicles, in terms of reliability and safety. For various electric vehicles including hybrid electric vehicles (HEV), plug-in hybrid electric vehicles (PHEV), and all-electric vehicles, battery packs are the most commonly used energy storage systems. For HEVs, Flywheel-based energy storage systems (FESS) have also received extensive attention. On the other hand, the electric motor is a key component of the traction system. Today, p...
