    摘要： There is provided a deceleration control apparatus for an automotive vehicle, including a target vehicle speed calculation unit that calculates a target vehicle speed and a deceleration control unit that performs deceleration control on the vehicle so that the vehicle reaches the target vehicle speed. The target vehicle speed calculation unit has a first target vehicle speed calculating section to give as the target vehicle speed a first target vehicle speed value by dividing a multiplication product of an estimated road friction coefficient and a predetermined target lateral acceleration limit by a determined actual yaw rate, and a target vehicle speed correcting section to correct the target vehicle speed depending on an accelerator pedal depression and a detected actual lateral acceleration, so as to adjust the amount of deceleration control on the vehicle.

    摘要： An upper limit of a target braking force for performing behavior control, and an upper limit of its variation rate, are limited so as not to produce hunting due to interference with an anti-skid control. A microcomputer comprising a braking force controller, in a step 81, calculates a target slip ratio (S1*) before limiting from a target braking force (F0*) before limiting and a wheel braking rigidity coefficient (ks), and when it is determined in a step 82 that (S1*) is larger than a maximum controllable slip ratio (Smax), in a step 84, limits a target slip rate (S2*) after limiting to (Smax) and limits the upper limit of target braking force after limiting, calculated by multiplying (S2*) by (ks), to a maximum value at which slip control is possible. In a step 85, a differential (&Dgr;S*) between (S2*) and a target slip ratio (S0*) on an immediately preceding occasion is taken as a target slip variation rate, and when it is determined in a step 86 that (&Dgr;S*) is faster than a predetermined value (&Dgr;S0), the slip ratio (S*) is determined, in steps 89, 90, according to the target slip variation direction determined in a step 87, so that the variation rate of the target slip ratio (S*) is equal to or less than (&Dgr;S0). In this way, the upper limit of the variation rate of the target braking force calculated by multiplying (S*) and (ks), can be limited.
