    • A reduction in pressure in tires fitted to follower wheels and driven wheels is precisely determined irrespective of slipping states of the driven wheels. A driven wheel slip rate calculating means M1 calculates driven wheel slip rates .lambda.L and .lambda.R. A driven wheel torque calculating means M2 calculates a driven wheel torque TQDW. A driven wheel slip rate estimating means M4 estimates a characteristic of variation in driven wheel slip rates .lambda.L and .lambda.R relative to the variation in driven wheel torque TQDW using a least squares method. A rotation-number ratio calculating means M5 calculates ratios CVWL and CVWR of the numbers of rotations of the follower wheels to the numbers of rotations of the driven wheels in a state in which the driven wheel torque in a graph of the variation characteristic is equal to zero. A tire pressure-reduction determining means M6 then determines a reduction in pressure from a difference in diameter between the follower wheels and the driven wheels by comparing the rotation-number ratios CVWL and CVWR with a reference value.

    • A first longitudinal grip force FGG is calculated by differentiating a vehicle body speed by time. A driven wheel torque is calculated from an engine torque and a second longitudinal grip force FGT is calculated from the driven wheel torque. The first longitudinal grip force FGG and the second longitudinal grip force FGT are compared with each other, and the higher one of such grip force is selected as a longitudinal grip force TG. When the vehicle travels on a normal flat road, the first longitudinal grip force FGG obtained from the vehicle body speed is selected. But when the vehicle travels on an ascent road, on which the first longitudinal grip does not indicate an accurate value, the second longitudinal grip force FGT obtained from the engine torque is selected. With this arrangement, the longitudinal grip force is accurately estimated even if the vehicle travels on such an ascent road.
    • 第一纵向夹紧力FGG是通过按照时间差分车体速度来计算的。 从发动机扭矩计算从动轮扭矩,并且根据从动轮扭矩计算第二纵向夹紧力FGT。 将第一纵向抓握力FGG和第二纵向抓握力FGT彼此进行比较,并且将这种夹持力中的较高者选择为纵向抓握力TG。 当车辆在正常平坦的道路上行驶时,选择从车体速度获得的第一纵向抓握力FGG。 但是,当车辆在上坡道上行驶时,第一纵向把手不指示准确值,则选择从发动机扭矩获得的第二纵向夹紧力FGT。 利用这种布置,即使车辆在这样的上升道路上行驶,也能够准确地估计纵向抓地力。
