摘要： In a traction control device in which an initial control torque of an engine is determined in accordance with an acceleration of the vehicle, when an excessive slipping of driven wheels is detected, a time taken for proceeding of the excessive slipping of the driven wheels from a large slip state to a small slip state is counted by a timer. If such time is smaller than a reference time and a gear ratio of the vehicle is of a first gear shift to provide a low vehicle speed, it is decided that the vehicle is traveling on an upward sloping road, and a lower limit value for defining the initial control torque of the engine determined in an initial control torque calculating means is corrected into an increased value in an initial torque correcting means. This prevents the initial control torque of the engine from being excessively reduced at the start of a traction control. By this construction, it is possible to prevent an initial control torque from being excessively reduced due to a misjudgment of a friction coefficient of a surface of an upward or downward sloping road to insure an acceleratability of a vehicle.

摘要： 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.

摘要： 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.

摘要： A slip rate of the driven wheel is calculated (at step S1). When the slip rate is smaller and when the slip rate is larger (at steps S2 and S3), estimated road surface friction coefficients MUTG and MUFG are determined by searching a table, based on a total grip force TGS or a longitudinal grip force FG determined from a vehicle acceleration (at steps S4, S7, S5 and S9). The larger one of the estimated road surface friction coefficients MUTG and MUFG is selected as MUCON (at steps S10, S11 and S12). A minimum total grip force TGMIN determined by searching a table and based on MUCON is compared with the total grip force TGS determined from the vehicle acceleration (at step S13), and the larger one of the minimum total grip force TGMIN and total grip force TGS is delivered as a total grip force TG for traction control (at steps S14 and S15). Thus, it is possible to estimate a correct total grip force, taking the road surface friction coefficient into consideration.

摘要： A traction control system for a vehicle includes a calculator for calculating a speed of a driven wheel of the vehicle, a calculator for calculating a vehicle speed and a calculator for calculating a slip rate of the driven wheel on the basis of the driven wheel speed and the vehicle speed, such that the feed-back control of a throttle valve is carried out to reduce the output torque from an engine to inhibit the excessive slipping of the driven wheel, when the slip rate exceeds a predetermined threshold value. The system further includes a calculator for calculating a total grip force of the vehicle, a calculator for calculating an initial engine required torque at the start of the feed-back control of the throttle valve on the basis of the total grip force, and a calculator for calculating an initial throttle opening degree of the throttle valve on the basis of the initial engine required torque. Thus, the excessive slipping of the driven wheels can be reduced without an abrupt change exerted to the behavior of the vehicle by setting an appropriate initial throttle opening degree.
