f: Use the relation in d) to write down the
transfer function between armature angle (output) divided by
armature current (input).
g: Show that the system is of first order, if the output is
considered to be motor speed.
h: State the time constant for the first order model.
j: Discuss whether the time constant could change
during the life of the vehicle. How critical are changes in the
system with regards to the time constant?
A large luxury 4x4 vehicle has been equipped with an electric park brake (EPB), as shown in Figure 26 Figure Q6: Electric park brake motor for a single disc brake a. Explain how the driver operates the EPB. (2 marks) b. Describe how an EPB can provide improved experience of driving the vehicle. (2 marks) C. Briefly describe the physical principles represented by each of the terms in the equation shown below. de de T(t) = 1 + B dta dt (2 marks) d. Explain briefly, why the EPB motor torque can be described by a constant times the armature current. State any assumption made. (2 marks) e. Convert the equation from partc) into the s domain.
