    • A target resultant force to be applied to a vehicle body is calculated, the magnitude of a critical friction circle of each wheel is estimated, and a critical resultant force is estimated from the estimated magnitude of the critical friction circle. Subsequently, a ratio of the target resultant force to a critical resultant force is set as an effective road friction, and the magnitude of a tire force is set by using the magnitude of the critical friction circle and the effective road friction. The direction of the tire force of each wheel to be controlled is set based on the sum of products, which are calculated for all other wheels, of a distance from the position of the wheel to be controlled to the position of the other wheel in a direction of the resultant force, and the magnitude of the tire force of the other wheel. Cooperative control of steering and braking or steering and driving of each wheel to be controlled is performed based on the magnitude and direction of the tire force which have been set.

    • Apparatus for improving the driving behavior of a vehicle is provided. The vehicle has front and rear axles, each having a plurality of wheels. Each wheel has a brake. Sensor are provided for measuring the rotational speed of each wheel, the vehicle yaw rate and the vehicle lateral acceleration. An anti-lock braking system provides first preset pressure values for controlling each brake, to prevent the wheels from locking during braking. A traction slip control system provides second preset pressure values for controlling each brake, to prevent the wheels from slipping during acceleration. A brake effort proportioning system provides third preset pressure values for distributing braking pressure between the wheels of the front axle and the wheels of the rear axle. A yawing moment controller provides fourth preset pressure values used to control each brake during cornering, to avoid application to the vehicle of an unbalanced moment which would cause the vehicle to understeer or oversteer. The antilock braking system, traction slip control system, brake effort proportioning means and yawing moment control system all operate independently of one another. A prioritizing mechanism applies criteria to determine a desired brake pressure that is applied to each wheel, based on the outputs of the antilock braking, traction slip control, brake effort proportioning, and yawing moment control systems.

    • A control process for the driving stability control of a motor vehicle is provided. The signal sent out by a control law unit to generate the necessary additional torque is sent to a distribution logic unit, which subsequently sends the pressure signals used to actuate the individual wheel brakes. The superimposition of these pressure signals and the pressure signal characterizing the driver's desire to brake (as well as the subsequent superimposition of these adjusting signals to adjusting signals arriving from other brake pressure controllers, such as ABS, TSC, EBV) leads to interfaces in which differing physical variables must be compared or superimposed. The necessary conversion of these variables is expensive and increases the inaccuracy of the control system. Simplified interfaces are provided, to achieve improved processing of the brake pressure desired by the driver, and possibly to avoid the conversion of the individual signal variables. Pressure gradient signals are sent, to the output of the distribution logic unit, and are superimposed with corresponding gradient signals from other brake pressure control circuits. A priority circuit processes the pressure signals of the individual wheels such that commands to reduce the pressure are processed first, after which the commands to hold pressure, and finally the commands to build up pressure are processed.
    • 提供了一种用于机动车辆的驾驶稳定性控制的控制过程。 由控制规则单元发出的用于产生必要的附加扭矩的信号被发送到分配逻辑单元,分配逻辑单元随后发送用于致动各个车轮制动器的压力信号。 这些压力信号的叠加和表征驾驶员制动欲望的压力信号(以及随后将这些调节信号叠加到从其它制动压力控制器(例如ABS,TSC,EBV)到达的调节信号的后续叠加)导致其中 必须比较或叠加不同的物理变量。 这些变量的必要转换是昂贵的并且增加了控制系统的不准确性。 提供简化的接口,以实现驾驶员期望的制动压力的改进处理,并且可能避免各个信号变量的转换。 压力梯度信号被发送到分配逻辑单元的输出,并且与来自其它制动压力控制电路的相应梯度信号叠加。 优先电路处理各个车轮的压力信号,使得首先处理降低压力的命令,之后处理保持压力的命令,最后处理建立压力的命令。
