Abstract: An anti-skid control apparatus for diagonally connected vehicle wheels including control valve devices arranged between fluid pressure generating chambers of a tandem master cylinder and the wheel cylinders of the front wheels, respectively, and a control unit receiving outputs of speed sensors for judging the skid conditions of the wheels and for instructing the control valve devices. The control unit determines the frictionally lower side of the road on which the wheels are running, and combines logically the judging result of the skid condition of the rear wheel running on that side of the road, with that of the front wheel running on that side. The apparatus then generates instructions for controlling the first or second valve device for the corresponding front wheel, and for controlling the second or first valve device for the other front wheel, on the basis of judging the skid condition of the other front wheel running on the other side of the road independently of the rear wheels. Alternatively, the apparatus may judge skid conditions of the rear wheels and the skid condition of one front wheel running on one side to control the valve device for the corresponding front wheel, and generate instructions to control another valve device for the other front wheel after judging the skid condition of the other front wheel running on the other side of the road.

Abstract: In order to control the wheel slip with an anti-lock brake system, in a vehicle with all-wheel drive and lockable differentials (29, 33), in particular with a lockable distribution differential (29), further braking pressure rise in the rear-wheel brakes (9, 10) is prevented for a predetermined period of time, with the locks (34, 35) engaged and with slip control activated. As a result, the driving stability of the vehicle is increased during braking with slip control and with the differential locks (34, 35) engaged.

Abstract: A slip-controlled brake system for motor vehicles with four-wheel drive, wherein one axle (VA) is driven permanently, and the second (HA) is driven by a differential-slip-sensitive coupling (6). The system comprises sensors (S1 to S4) for determining the rotational behavior of the wheels, electronic switching circuits (38, 39, 40) and an auxiliary-pressure supply system (18). For the traction slip control action, brake pressure is introduced into the wheel brakes (11, 12) of only one axle, preferably the permanently driven axle (VA), and the traction slip of all wheels (VL, VR, HL, HR) is, however, controlled thereby. The electronic switching circuits (40) are preferably provided such that the traction slip control action will only set in when, at least at one wheel of the axle (HA) which is not connected to the traction slip control system, an increased traction slip occurs.

Abstract: A motor vehicle comprises two driven axles (5, 8), which are interconnected by an interaxle coupling (10) for transmitting a torque only when the halves of the coupling (10) rotate at different speeds and by a speed-changing transmission (9) connected in series with the coupling (10). A brake system (12 to 15) is provided for braking the wheels of both axles (5, 8). In order to ensure that the wheels of the driven rear axle (8) will not block before the wheels of the driven front axle (5), a pressure-setting controller (17) is adapted to control a brake pressure regulator (16) associated with the driven rear axle (8) and is responsive to a reversal of the direction in which torque is transmitted to and from the driven rear axle (8). During a transmission of torque from the driven rear axle (8) to the driven front axle (5), the pressure-setting controller (17) substantially reduces in dependence on the value of the torque being transmitted the pressure which is applied to brake the wheels of the driven rear axle (8) relative to the pressure which is applied to brake the wheels of the driven front axle (5).

Abstract: A slip-controlled hydraulic brake system for all-wheel driven motor vehicles equipped with lockable differentials (2, 3) is provided with sensors (S.sub.1 -S.sub.4, 33-36) for measuring the rotational behavior of the wheels. Electronic circuits (44) are provided for logic combining and processing the sensor signals, and for generating braking pressure control signals by way of which the brake pressure in the individual wheel brakes (16-19) is variable in response to the rotational behavior of the wheels and to a reference variable. To compensate the increased moments of inertia as a result of the moments transmission, by way of the lockable differentials (2, 3) in this brake system the brake pressure in the rear-wheel brakes (18, 19), can be modulated at a lower control frequency as compared with the brake pressure in the front-wheel brakes (16, 17). The reduction in the control frequency of the rear-wheel brake pressure is determined by driving-dynamic criteria, for example, by the average motor vehicle deceleration or by the motor vehicle speed.

Abstract: A slip-controlled brake system for all-wheel drive motor vehicles is provided with differentials (16,19,20) for balancing track difference between the individual wheels (VR, VL, HR, HL). Wheel sensors (31-34) and electrical circuits (9) for generating brake pressure control signals are provided to control the brake pressure in the event of imminent locking. A disconnecting clutch (37) is inserted into a driving split axle (25) connecting a wheel to the rear axle differential (20). The disconnecting clutch (37) can be actuated either electromagnetically or hydraulically. Upon commencement of the brake slip control or at a predetermined time thereafter, the disconnecting clutch (37) is disengaged thereby rendering the coupling between the rear wheels and/or between front and rear axles ineffective thereby to permit an individual slip control by way of the individual control channels.

Abstract: To control the braking pressure in the wheel brakes of a slip-controlled hydraulic brake system for automotive vehicles with all-wheel drive and with lockable or automatically locking differentials (2, 3), a circuit configuration is provided which influences the variation of the vehicle reference speed (v.sub.REF). This is to say, in the event of the wheel (v.sub.Rn) which is momentarily decisive for the formation of references becoming instable, the reference speed (v.sub.REF) will first be declined with a relatively flat gradient which corresponds to a vehicle deceleration at a low frictional coefficient. A decrease of the vehicle reference speed (v.sub.REF) with a very steep gradient will follow after a predetermined period of time (T.sub.1). This decrease is continued until the vehicle reference speed (v.sub.REF) reaches the decisive wheel speed again or falls thereunder. To avoid oscillations, the change-over of the reference (v.sub.REF) after the attainment of the wheel speed curves (v.sub.Rn) will not be effected until after a predetermined time of delay (T.sub.2 or T.sub.3).

Abstract: The coefficient of friction of a road surface lying ahead of a four-wheel drive vehicle is predicted and, if control performed on the basis of the prediction is incorrect, the coefficient of friction of the road surface actually traversed by the vehicle is calculated, thereby revising the prediction so that the next prediction of coefficient of friction will be more accurate. Accordingly, control for changeover between two- and four-wheel drive or for locking a center differential mechanism can be made to conform to the road surface conditions immediately and in an appropriate manner to prevent skidding or lock-up of the tires and, hence, assure a safe and stable traveling state.
