A differential rotation control apparatus (4) for a vehicle having a differential (2), left (10L) and right (10R) output shafts of the differential, and left (11L) and right (11R) axle shafts, comprises variable displacement type left (3L) and right (3R) h...

The method involves detecting the input parameters, comparing an actual direction of motion (BR) derived from the steering angle (LW) with a desired direction of motion, increasing the yaw damping of the coupling between front and rear axles if the two val...

A clutch torque computing unit calculates a final clutch torque by changing the ratio of the clutch torques obtained through feedback control and feed forward control according to the diameter difference of a tire calculated by a tire diameter difference c...

The method involves detecting at least the driving speed (v), transverse acceleration (aq) and current steering angle (LWakt), taking a characteristic field steering angle (LWKF) relating to the driving speed and transverse acceleration from a characterist...

Method for automatic control of at least one differential lock in the drive train of a motor vehicle, especially an all-wheel drive vehicle that has sensors that generate impulses representative of wheel rotation. The sensor signals are fed to a control un...

A center differential limiting control unit (40), calculates and sets a vehicle speed, a target difference in a rotational speed between front and rear axle shafts (13FR,13FL,13RR,13RL), a control start difference in the rotational speed, and an actual dif...

The method involves feeding wheel sensor pulses to the controller for vehicle speed determination and controlling the lock accordingly. The wheel circumference difference is determined by summing pulses for each wheel over a defined period and aligning it ...

A driving force control system for a four-wheel drive vehicle is disclosed which enables the vehicle to smoothly start on a low- mu road surface, and is capable to distributing just required amounts of driving forces to auxiliary drive wheels depending on ...

The method involves briefly engaging and releasing the clutch to accelerate the gearbox input shaft in the engine's rotation direction and synchronizing a forward gear by accelerating the input shaft to a speed resulting from the transmission ratio and the...
