| description | A physical quantity detection device (10) detects a plurality of different physical quantities on the basis of an output signal waveform. A strain sensor (3), which is a single sensor element, outputs a sensor signal waveform (15) having a reference level (151), a positive level that varies positively with respect to the reference level (151), and a negative level that varies negatively with respect to the reference level (151). An estimation unit (4) estimates a first physical quantity corresponding to a peak value (152) of a positive level and a second physical quantity corresponding to a peak value (153) of a negative level on the basis of a sensor signal waveform (15) output by a strain sensor (3).
本发明的物理量检测装置(10)根据输出的信号波形来检测多个不同物理量。作为1个传感器元件的应变传感器(3)输出传感器信号波形(15)，所述传感器信号波形(15)具有基准电平(151)、相较于基准电平(151)而言朝正变化的正电平、以及相较于基准电平(151)而言朝负变化的负电平。推定部(4)根据应变传感器(3)所输出的传感器信号波形(15)来推定与正电平的峰值(152)相对应的第1物理量和与负电平的峰值(153)相对应的第2物理量。 |
