Research on Electromagnetic Compatibility Optimization Design of Vehicle Speed Sensor

Aiming at the electromagnetic compatibility problem faced by a certain type of vehicle speed sensor, the reason of radio frequency radiation is analyzed, and the optimization design algorithm of electromagnetic compatibility of chaotic neural network is put forward. In this method, we use the parallel search method for multiple variables which will be optimized and the feedback network model to narrow the search space to find the global optimal solution. The experimental results show that the proposed algorithm can effectively reduce the peak value of the RF energy of the sensor. The electromagnetic compatibility test results of the optimized vehicle speed sensor accord with the general error standard of the general technical condition of the speed sensor.
