即，有计算出的车轮速度的精度降低，计算出的车速的精度降低这样的问题

Benefits of technology

[0007]根据上述构成，能够基于来自上述传感器的检测信号估计车辆的移动距离并控制对车辆赋予的制动力。即，能够不使用基于来自上述传感器的检测信号计算出的车辆的速度，控制制动力。若与基于来自上述传感器的检测信号作为速度计算出的车速进行比较，则能够减轻如上述那样计算出的车轮基准距离相对于实际的值的精度的降低。因此，即使成为检测车速的精度较低的状况，也能够减轻对控制制动力的精度给予的影响。

Abstract

A vehicle (90) to which a control device (10) as a brake control device is applied has a sensor (81) capable of acquiring a rotation angle of a wheel (91). The control device (10) includes a first distance calculation section (12), a second distance calculation section (13), and a brake control section (11). The first distance calculation section (12) estimates a front-rear acceleration of the vehicle (90) based on a reference braking force corresponding to an operation amount of a brake operation member, and calculates a braking force reference distance that estimates a moving distance to a stop of the vehicle (90) based on the front-rear acceleration. The second distance calculation section (13) calculates a wheel reference distance that estimates a moving distance of the vehicle (90) based on a detection signal of the sensor (81) and a diameter of the wheel (91). The brake control section (11) executes feedback control that controls a braking force applied to the vehicle (90) so as to make a difference between the braking force reference distance and the wheel reference distance small.
