Title:
BRAKE DEVICE
Document Type and Number:
Japanese Patent JP2015085869
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a brake device that can impart appropriate thrust (braking force) after succeeding ignition-on (system startup) without requiring measurement of elapse time by a timer after ignition-off (termination of system control).SOLUTION: A parking brake control device, when receiving an operation demanding signal, adds a thrust correction value Δ F, calculated based on a difference between a temperature at completion estimation value te and an ambient temperature at restart-time ts which are memorized by a memorizing portion when a control is completed, to target thrust to be set depending on an estimated temperature at the time of receiving the signal. The parking brake control device drives an electric actuator so that the target thrust becomes a corrected target thrust to which the thrust correction value Δ F is added.
