Fig. 2 is the positional error antidote control flow chart of the relevant automobile drive electric motor of one embodiment of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, describe the positional error antidote of the relevant automobile drive electric motor of embodiment of the present invention in detail.
Fig. 2 is the control flow chart of positional error antidote of the automobile drive electric motor of one embodiment of the present invention.Other controller interlocks of the controller of control automobile drive electric motor and vehicle can receive the information relevant with vehicle thus.
At first, when beginning the positional error correcting function of magslip, the controller of automobile drive electric motor receives first a reference values such as the speed of a motor vehicle, engine speed, the instruction of motor torsion and braking mode from other controllers of vehicle, and second a reference values (S202) such as running car distance, running time or the number of starts behind the correction value of the positional error antidote rectification of the relevant automobile drive electric motor of preservation present embodiment.
Next, the controller of automobile drive electric motor utilizes above-mentioned first reference value, judge whether vehicle is halted state, whether motor speed satisfies the first condition of engine idling and the instruction of motor torsion reaches the 3rd above condition of certain value for second condition and the brake weight of ' 0', utilize the second above-mentioned a reference value to judge then, whether reach in order to correct travel the cycle (S205) that present embodiment relevant position error is set in advance.
Whether at this, reaching more than the certain value as the brake weight of the 3rd condition is in order to prevent, when implementing magslip positional error correcting function, because positional error and vehicle that contingent some torsion causes moves.
