According to the technical solutions described herein, an example method for frequency tracking based friction detection includes receiving, by a filter module, an accelerometer signal from an accelerometer coupled with an assist torque system. The method further includes estimating, by the filter module, harmonic content in the accelerometer signal based on an order frequency of the assist torque system. The method further includes in response to the harmonic content that is detected being greater than or equal to a predetermined threshold, initiating a friction estimation in the assist torque system. The method further includes adjusting an amount of torque being generated by the assist torque system based on an estimated friction in the assist torque system.
