摘要： A braking force control device can control braking forces of the respective wheels of a vehicle, suppresses an increase of the braking force of a first wheel that is a wheel having a relatively large slip amount in a pair of right/left wheels and increases the braking force of a second wheel that is a wheel having a relatively small slip amount. The braking force control device may suppress the increase of the braking force of the first wheel before the friction coefficient of a road surface to the first wheel reaches a peak and when the friction coefficient is in the vicinity of the peak. It is preferable to suppress the increase of the braking force of the first wheel by holding the braking force of the first wheel.

摘要： A signal indicating an estimated body deceleration and a deceleration indicated by a detection signal from a G sensor are pass through first and second filters having different filter constants. Based on a resulting difference in response speeds thereof, it is determined whether sudden braking, i.e., quick depression, is being performed. If quick depression is determined, then even if an upper limit of a W/C pressure to rear wheels is set in order to prevent rear wheel locking precedent to front wheel locking, the W/C pressure is increased so as to exceed such an upper limit. Thus, a greater deceleration can be achieved than when the W/C pressure at the set upper limit is generated.

摘要： A brake fade determination device determines whether a fade state of a brake device that brakes a wheel of a vehicle is occurring on the basis of the deceleration of the vehicle and the slip amount of the wheel. A braking system includes: the brake device that is able to adjust a braking force that acts on the wheel of the vehicle; and a controller that controls the braking force to control the slip condition of the wheel. The controller determines whether a fade state of the brake device is occurring on the basis of the deceleration of the vehicle and the slip amount of the wheel, and adjusts the amount of increase or decrease in braking force on the basis of whether the fade state is occurring.

摘要： If a condition for starting a yaw control during an antiskid control is met while the antiskid control is being executed on one of right and left front wheels during braking on a uneven friction-coeffient road surface, the reference value for making the determination to start the antiskid control on the other one of the front wheels is reduced, and therefore the antiskid control is started at an earlier timing. If the antiskid control is executed on the wheel, the brake pressure of the wheel is controlled in a pre-set specific pattern.

摘要： A brake operating speed detecting device includes a plurality of filters having different cut-off frequencies and inputs thereto a vehicle body deceleration that changes at the time of braking. The state of distribution of output values obtained through the filters, or the difference d between the output values, corresponds to the rising speed of the vehicle body deceleration. Because the rising speed corresponds to the brake operating speed, the brake operating speed can be detected from the state of distribution of the output values or the difference d.
