    Abstract: 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.

    Abstract: 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.

    Abstract: An apparatus for controlling a DC motor connected to an intake throttle valve in an internal combustion engine to detect an actual opening degree of the intake throttle valve and to match the actual opening degree with a command opening degree. The apparatus includes a feedback loop for defining a feedback signal indicative of a command to converge the actual opening degree of the control member to the command opening degree by reception of the command opening degree delivered by a command opening degree generating means and the actual opening degree delivered by an actual opening degree detecting means, a combined-signal generating means for combining the feedback signal defined by the feedback loop with the command opening degree delivered by the command opening degree generating means, and a motor driving means for driving the DC motor in response to an output from the combined-signal generating means. Thus, it is possible to converge the actual opening degree of the intake throttle valve to the command opening degree with a good responsiveness and a good positioning accuracy.
