Abstract:A digital system is implemented in a FPGA (Field Programmable Gate Array) for detecting the locking differential need detection for front or rear differentialsfor a 1:10 scale RC vehicle. The detector isbased on wheel speed difference and the drive shaft speed. First it was implemented a Data Acquisition System (DAQ) in the FPGA for data analysis for different driving situations and then it was developed the detection system. The detector could differentiate between normal driving condition (vehicle turning) and driving conditions when a locking differential is needed. The detectorwas implemented easily using a true table, and it gives the driver information of which wheel loose traction and if it is necessary to lock the differential. Keywords:locking differential, detection system, FPGA, wheel speed difference.
