Title:
電動パーキングブレーキシステム
Document Type and Number:
Japanese Patent JP4470928
Kind Code:
B2
Abstract:
During the standstill state maintenance control executed by an electric parking brake system, the moving force-based target tension Frefb is determined based on the inclination angle of a vehicle and the shift position each time the predetermined program is executed, and the tentative target tension Fref(n) in the current routine is set to a smaller value from among the moving force-based target tension Frefb and the maximum value Fmax. The control target tension Fref(n)* is set to a larger value from among the control target tension (the final target tension) Fref(n−1)* in the immediately preceding routine and the tentative target value Fref(n). Even if the tentative target tension Fref(n) is smaller than the control target tension Fref(n−1)*, the control target value Fref(n)* is not set to a value smaller than the control target tension Fref(n−1)*.
