摘要： PROBLEM TO BE SOLVED: To provide a brake control device capable of determining whether a motor runs idle without driving the motor for a long time.SOLUTION: When determining whether the motor runs idle, the brake control device drives the motor 60 twice, on the first try drives the first hour motor, and on the second try drives the second hour motor, which is longer than the first hour motor. Furthermore, the brake control device determines whether the motor runs idle by determining whether or not the difference between the first and second voltage drop hours MT1 and MT2 in which generated voltage (MT) by the motor 60 after the stop of the motor 60 lowers to a predetermined threshold voltage is not less than a threshold hour on the first try and second try respectively. In this manner, the motor driving hours of the first try and the second try is changed so that the brake control device can determine that the motor runs idle based on the difference between the first and second voltage drop hours MT1 and MT2 even if the viscosity of brake fluid or grease, etc. applied on a rotary shaft of the motor 60 becomes high, for example, at extremely low temperature. Therefore, the brake control device can determine that the motor runs idle even without driving the motor for the long time.

解决方案：当确定电机是否空转时，制动控制装置驱动电机60两次，第一次尝试驱动第一小时电机，第二次尝试驱动比第一小时电机长的第二小时电机小时电机。此外，制动控制装置通过判定电动机60停止后的电动机60的发电电压（MT）是否降低到第一和第二电压下降时间MT1和MT2之间的差，判定电动机是否空转分别在第一次尝试和第二次尝试时预定阈值电压不小于阈值小时。以这种方式，改变第一次尝试和第二次尝试的电动机驱动时间，使得制动控制装置可以基于第一和第二电压下降小时MT1和MT2之间的差来确定电动机怠速，即使粘度施加在电动机60的旋转轴上的制动液或油脂等变得高，例如在极低温度下。因此，即使长时间不驱动电机，制动控制装置也能够判定电动机怠速运转。版权所有（C）2013，JPO＆INPIT
