In order to ensure production quality, the device needs to have some statistical production process capability, and help reduce the production of quality degradation due to human factors issues. Integration, intelligence is the development trend of automotive sensors. If only the final detection test automotive sensor type, found the problem too late automotive sensors, so often the test will be the production process and interaction. Thus, on the one hand require test equipment and other equipment on the production line supplier of automotive sensors good convergence, on the other hand can achieve information and data sharing between devices. Static characteristics of the sensor sensitivity parameter index ⒈ Sensitivity refers to incremental and steady-state input sensor output y and input x ratio automotive sensor manufacturer, or the output of the x-y increment ratio, expressed as with k k = the minimum amount of change to be measured dY / dX ⒉ resolution of the sensor within a predetermined measurement range can be detected is called the resolution. ⒊ measurement range and the range is within the allowable error limit is the lower limit of the range between the upper limit of the measured values ??is called the measurement range. ⒋ linearity (nonlinear error) under specified conditions, sensor calibration curve fitting with the percentage of the maximum deviation of full scale output value is called a straight line between the linearity or nonlinearity error. ⒌ Hysteresis Hysteresis is under the same operating conditions, the trip characteristics are inconsistent with the degree of anti-stroke characteristic of the sensor. ⒍ Repeatability Repeatability is under the same operating conditions, the input in the same direction over the entire measurement range resulting characteristic curve varies continuously repeated inconsistencies. ⒎ zero drift and drift sensor when there is no input or another value, at a certain time, the percentage of the maximum deviation of the input values ??deviate from the original show and the full-scale value of zero drift. The temperature is increased by 1 ℃, the percentage of the maximum deviation of the full scale of the sensor output value, called drift.
