摘要： A pair of shoes are expanded by driving an electric brake motor. Due to the friction engagement of the shoes with a drum inner peripheral surface, a braking force is applied to a wheel. An actual braking torque is detected by a strain sensor that detects the load applied to an anchor pin. Through a feedback control using the actual braking torque, the electric motor is driven and controlled so that the actual braking torque becomes equal to a target braking torque that is determined in accordance with the amount of operation of a brake pedal. When the actual braking torque is undetectable, for example, during a stop of a vehicle, the electric motor is driven and controlled through an actuating force control using the current through the electric motor that is detected by a motor current sensor. The braking torque control apparatus controls the actual braking torque to a magnitude corresponding to brake operation, regardless of the magnitude of the coefficient of friction between a friction engagement member and brake rotor. Even when the braking torque is undetectable, the apparatus executes brake control in a good manner.
摘要翻译：通过驱动电动制动马达来扩展一双鞋。由于鞋与滚筒内周面的摩擦接合，对车轮施加制动力。通过应变传感器检测实际的制动转矩，该应变传感器检测施加到锚销的负载。通过使用实际制动转矩的反馈控制，电动机被驱动和控制，使得实际制动转矩等于根据制动踏板的操作量确定的目标制动转矩。当实际制动转矩不可检测时，例如在车辆停止期间，通过使用由电动机电流传感器检测的电动机的电流的驱动力控制来驱动和控制电动机。制动转矩控制装置将实际的制动转矩控制到与制动操作相对应的幅度，而与摩擦接合构件和制动转子之间的摩擦系数的大小无关。即使在制动转矩不可检测的情况下，该装置以良好的方式执行制动控制。
