PROBLEM TO BE SOLVED: To provide a vehicle braking control device, which is configured to be able to suppress both braking force of left and right rear wheels from being enhanced even if low rear-wheel braking force characteristics are employed to secure braking stability in a high-speed area of a vehicle, when executing left and right wheel independent control so that respective slip rates of the left and right rear wheels approximate an average value of slip rates of left and right front wheels.SOLUTION: In a vehicle 1 equipped with a brake device 20 that can control independently braking force of left and right rear wheels 10R, left and right wheel independent control is executed so that respective slip rates S of the left and right rear wheels 10R approximate a common target slip rate St. In a high-speed area of the vehicle 1, the left and right wheel independent control is executed when deceleration G is equal to control start Gth2 lower than control start Gth1 which is used in a low-speed area or more. In the low-speed area, an average value of slip rates S of left and right front wheels 10F, or a base value Stb, is used as a target slip rate St, and in the high-speed area, a value to be obtained by multiplying the base value Stb by a correction coefficient K is used as the target slip rate St.SELECTED DRAWING: Figure 6

    【課題】左右後輪のそれぞれのスリップ度合いが左右前輪のスリップ度合いの平均値に近づくように左右輪独立制御を実施する場合に、車両の高速域での制動安定性の確保のために後輪低制動力特性が採用されていても左右後輪の双方の制動力が高められることを抑制できるようにする。【解決手段】左右の後輪10Rの制動力を独立して制御可能なブレーキ装置20を備える車両1において、左右の後輪10Rのそれぞれのスリップ率Sが共通の目標スリップ率Stに近づくように左右輪独立制御を実行する。左右輪独立制御は、車両1の高速域では、減速度Gが、低速域で用いられる制御開始Gth1よりも低い制御開始Gth2以上であるときに実行される。低速域では、左右の前輪10Fのスリップ率Sの平均値であるベース値Stbが目標スリップ率Stとして使用され、高速域では、ベース値Stbに補正係数Kを乗じて得られる値を目標スリップ率Stとして使用される。【選択図】図6
