Steer motor circuit limit method

摘要

In the present invention, the motor current limitation algorithm of motor driven power steering (MDPS), which is a power steering apparatus, directly calculates the loss energy (thermal energy) for the detected motor current, not the temperature, Since it is implemented with only a purely variable algorithm that controls the variable, it is possible to solve the low accuracy which is caused by using the temperature sensor, to increase the auxiliary steering force (braking force) through the real time optimum motor control, So that the cost is not increased.;Motor, Adjustable Current, Loss Energy
