Problems solved by technology

[0003] The disadvantage of controlling the braking device in this way is that the result to be avoided is actually used as a measured variable for controlling said braking device, that is to say, the feedback is only used when full or at least partial locking occurs. given to the braking device
The downside of this is that only a limited number of properties can be recorded, so the chances of the selected properties matching the actual situation are also limited

Embodiment Construction

[0016] Figures 1 and 2 are used to illustrate the directions of forces and their corresponding designations used herein. Figure 1 schematically shows an example of a vehicle, here a car with four wheels. The straight ahead direction of travel is indicated by an arrow A in front of the vehicle. Two forces are shown near the center of the car, the longitudinal force F lon and lateral force F lat . In FIG. 2 the wheel 10 is shown in contact with a road surface 20 . Two more forces are drawn at the contact between the wheel and the road surface, the longitudinal force F in the direction of travel lon , in this case it is the acceleration force since it is in the direction of arrow A in Figure 1. If it is in the opposite direction, then it is the braking force; the other force is the vertical force F vert .

[0017] An automobile, as shown in FIG. 1, is equipped with braking devices on its four wheels, which are controlled by ABS. In addition to the measuring device for mea...

Abstract

A power steering system for a vehicle includes a hydraulic pump interconnected with a power steering gear and a fluid coupling that operatively connects a drive shaft of an engine of the vehicle with the hydraulic pump. The power steering system also includes an electronic controller operable to provide a variable control signal based on received input and a power electronic converter that energizes the fluid coupling in response to the control signal to vary torque transmitted via said fluid coupling.

Description

technical field [0001] The invention relates to a control system for braking and / or driving wheels, in particular a control system for vehicles with wheels, wherein at least one wheel is connected to a braking and / or driving device for the wheels, said control system Comprising a measuring device and a control unit connected to the measuring device, the measuring device is used to measure the rotation speed of the wheel, the longitudinal force and the vertical force generated by the contact part of the wheel with the road surface, and the control unit is used to control the Braking and / or driving of wheels. Background technique [0002] Control systems for vehicles with wheels have been known for some time, such as anti-lock braking systems (ABS) for braking devices. The known device measures the speed of rotation of a wheel equipped with a braking device. If the rotational speed of a wheel deviates (strongly) from the speed of the other wheels, or if the rotational speed ...
