Method for measuring speed-dependent parameter of pulse width modulation controlled electric motor in motor vehicle braking apparatus, involves carrying out time-sampling process of electrical characteristic of motor at certain points

摘要

The method involves carrying out time-sampling process of the electrical characteristic of motor at certain discrete points and obtaining digital sampling signals. The obtained digital sampling signal is transmitted to a digital integrator for sensing the electrical characteristic of the motor within a pulse interval, while carrying out pulse-width modulated control of the motor. An independent claim is included for motor vehicle braking apparatus.
