摘要： A motor driven brake apparatus is provided for braking a wheel mounted on a knuckle, and includes a brake member rotated integrally with the wheel, a friction member mounted on the knuckle to be capable of being in contact with the brake member, and an electric motor for driving the friction member toward the brake member to be in contact therewith. The motor is adapted to press the friction member onto the brake member to restrain the wheel from rotating. And, a motion converter is accommodated in an opening portion of the knuckle for converting rotating force of the motor into pressing force applied by the friction member onto the brake member. The motion converter is connected to the motor at a side thereof facing the vehicle body, and the motor is mounted on the knuckle.

摘要： The brake control apparatus sets a target deceleration (1) in accordance with an amount of operation of the brake pedal. It calculates another target deceleration (2) on the basis of the target deceleration (1). In this calculation, limit values of deceleration increasing and decreasing gradients with respect to the target deceleration (1) are set on the basis of the target deceleration (1), and then the target deceleration (2) is obtained by correcting the target deceleration (1) on the basis of the established deceleration increasing and decreasing gradients. Accordingly, the deceleration increasing/decreasing gradient becomes small when braking is gentle. This makes it possible to curb an abrupt change in brake force to achieve smooth brake control. Further, the deceleration increasing/decreasing gradient becomes larger when braking is abrupt. Accordingly, it is possible to create a great change in brake force to provide a high response.
摘要翻译：制动控制装置根据制动踏板的操作量设定目标减速度（1）。根据目标减速度（1）计算另一个目标减速度（2）。在该计算中，基于目标减速度（1）设定相对于目标减速度（1）的减速度增减梯度的极限值，然后通过校正目标减速度（ 1）根据建立的减速度增减梯度。因此，当制动平缓时，减速度增减梯度变小。这样可以抑制制动力的突然变化，以实现平稳的制动控制。此外，当制动突然时，减速度增减梯度变大。因此，可以产生很大的制动力变化以提供高的响应。

摘要： A vehicular motor-driven brake apparatus includes an open circuit in which reciprocation of a master cylinder generating a brake pressure is caused by an actuator that operates according to a pedal operation amount, and brake fluid discharged from a wheel cylinder during pressure decrease is directly returned to a master reservoir subject to atmospheric pressure. A fluid amount replenishment control is executed during pressure increase of the master cylinder in which a master stroke is returned for only a predetermined time by operation of the actuator, and thus brake fluid is sucked up from the master reservoir to the master cylinder. Accordingly, when an ABS control continues for a long time period, even if the brake pedal is being depressed, reduced pressure brake fluid in the master cylinder is sucked up. Therefore, there is no limit to pressure decrease, and bottoming-out of the master cylinder does not occur.
摘要翻译：一种车辆用电动制动装置，其特征在于，具有开闭回路，在所述开路中，产生制动压力的主缸的往复运动是由根据踏板操作量进行动作的致动器引起的，在减压期间从轮缸排出的制动液直接返回到受大气压力影响的主油库。在主缸的压力增加期间执行流量补充控制，其中通过致动器的操作使主冲程仅返回预定时间，并且因此制动流体从主油箱被吸入主缸。因此，当ABS控制持续长时间时，即使制动踏板被压下，主缸中的减压制动液被吸入。因此，压力降低没有限制，不会产生主缸的底部泄漏。

The lever-ratio-changing mechanism includes a link member provided on one side of the brake pedal lever and rotatably attached thereto via a support shaft. The link member is linked to a rear end portion of the output member via a link shaft provided on the link member at a position offset radially from the support shaft by a predetermined amount. An interlocking mechanism is provided on the side of the brake pedal lever and between the stationary member and the link member. The interlocking mechanism causes the link member to rotate about the support shaft in accordance with pivotal movement of the brake pedal lever.

摘要： A brake operation amount detection device detects an operation amount of a brake pedal, and a target deceleration computation device computes a target deceleration corresponding to an operation amount that the driver intends to achieve. Further, an actual deceleration calculation device calculates an actual deceleration. A deviation between the target deceleration and the actual deceleration is obtained as a difference level, and a warning issuing device generates a sound having a volume that increases in accordance with the magnitude of the difference level. Accordingly, in the case that the brake does not act, contrary to the driver's expectation, even when the driver presses down the brake pedal, the driver can recognize a degree of difference from the driver's braking intention, based on the magnitude of the sound. Therefore, the driver does not feel a sense of danger or fear.
