Abstract: A controller (5) controls the engaging force between a pump impeller (1a) connected to an engine (2) and a turbine runner (1b) connected to an automatic transmission (23). The controller (5) first performs feedforward control of the engaging force. The controller (5) determines a reference value and a target rotation speed based on the capacity characteristics of the torque converter (1), and if the rotation speed of the engine (2) becomes less than the reference value, performs feedback control of the engaging force so that the deviation between the target rotation speed and the rotation speed decreases. When a predetermined condition is satisfied, the controller (5) changes over from feedforward control to feedback control, even if the rotation speed of the engine (21) is not less than the reference value. As a result, the control precision of feedback control when performing a slip lock-up, is increased.

Abstract: In an antiskid braking system for increasing or decreasing a braking force according to a wheel speed and a vehicle speed, an algorithm applied to the determination of a braking force decrease amount is improved. Once a target braking force decrease amount is determined according to the wheel speed and vehicle speed, this is compared with a predetermined minimum decrease amount, and when the target decrease amount is less than the minimum decrease amount, braking force is decreased according to the minimum decrease amount. The minimum decrease amount is preferably determined according to the braking force immediately before the braking force decrease. In this way, braking force reduction insufficiencies in several conditions are prevented.

Abstract: In a vehicle driving force control apparatus for controlling a driving force of the vehicle to achieve a target acceleration or a target vehicle speed, a running resistance estimating section calculates an estimated running resistance. A target acceleration modifying section modifies the target acceleration with the estimated running resistance and thereby decreases the target acceleration with increase in the estimated running resistance.

Abstract: An anti-skid brake control system comprises a limiter which provides an upper limit of variation of wheel speed indicative data. The limited wheel speed indicative data is derived with respect to each wheel. The greatest limited wheel speed indicative data is selected as vehicle body speed indicative initial data. The anti-skid brake control system derives a projected vehicle body speed indicative data by adding an integrated value of a longitudinal acceleration to the aforementioned vehicle body speed indicative initial data. The integrated value is provided with a predetermined offset value for compensating for error caused in a longitudinal acceleration sensor.
