Application technology? free detection system based on intermediate frequency detection technology (referred to as intermediate frequency HOD), application field: intelligent driving, unique advantages: 1.
Innovation: the core value of HOD and steering wheel heating through time-sharing multiplexing of the same wire (TDM) is reflected in its innovative and simplified design, which makes full use of the physical properties of the wire.
The steering wheel heating wire is directly reused as the sensor of HOD.
Through the application of time-sharing multiplexing wire technology, we have successfully integrated the steering wheel heating and hands-off sensing function.
When heating is carried out, the wire is used for steering wheel heating.
when the off-hand detection function is carried out, the wire is used for the out-of-hand detection sensor.
Due to the reuse of heating wire as sensor, HOD must adopt a unique algorithm in filtering, RawData processing, correction compensation, temperature compensation, electrical performance optimization and other aspects.
The scheme uses a specific filtering algorithm to solve the problem of digital filtering delay, which not only ensures the effectiveness of the filter, but also takes into account the real-time performance, and ensures that the in-hand and out-of-hand information can be detected in a very short time.
Through the special operation of RawData, that is, temperature correction, the detection accuracy will not be affected when the temperature changes greatly.
The system optimizes the reuse scheme of heating and detection, carries out in-hand and off-hand detection as closely as possible while ensuring the heating efficiency, and uses an independent signal protection circuit to ensure the integrity of the detection signal.
so that the detection function is not affected by the heating function.
