  • Patent number: 8204669
    Abstract: The present device relates to a method for regulating the driving dynamics of a vehicle, in which at least one wheel of the vehicle is acted upon by a torque on the basis of control of a clutch transmitting a torque to the wheel and/or on the basis of control of a differential distributing torque to the wheel and at least to one other wheel. The method is characterized in that a value of the torque is determined as a function of a first and a second value of a yaw moment.

  • Publication number: 20050234628
    Abstract: Currently available driving dynamics control systems such as ESP or TCS require in the driving dynamics limit range information about the actual maximum coefficient of friction between tires and roadway to function reliably. A proven approach is to use, once the control is active, the actual utilization of grip as the maximum coefficient of friction. The object of the invention relates to a method for determining the actual maximum coefficient of friction independently of the activation of the control. The method permanently determines values which are representative of the utilization of grip in longitudinal and/or lateral direction, based on measured and/or estimated variables that represent the actual longitudinal forces, lateral forces and vertical forces acting upon the individual wheels and tires, while using measured or calculated actual state variables representative of the tire slip angle and/or the tire slip angle velocity and/or the longitudinal slip and/or the longitudinal slip velocity.

  • Patent number: 6954691
    Abstract: A method for the online determination of values of driving dynamics for a motor vehicle. To improve the quality of the control of a motor vehicle and to reduce the demands placed on the driver, the invention discloses a driving dynamics control including the (1) estimated output quantities ?m in dependence on determined or estimated input quantities u and predetermined or predicted vehicle state variables {circumflex over (x)} and optionally further quantities, (2) comparing the estimated output quantities ?m with measured output quantities ym, and (3) determining the estimated driving dynamics quantities {circumflex over (x)}(tk/tk) in dependence on the measurement result and, as the case may be, further criteria.

  • Publication number: 20050173980
    Abstract: The most important aspect of brake systems in motor vehicles functioning according to the brake-by-wire principle is that the driver's braking requirements are detected quickly and reliably. Fulfilling this requirement primarily depends on the pedal sensor system associated with the brake pedal and its measuring devices for determining the characteristic values of the brake pedal actuation. The present invention provides for at least two measuring devices for determining the braking requirement, with such measuring devices sensing the same characteristic value of the brake pedal actuation, e.g. the brake-pedal actuation force, brake-pedal travel or brake-pedal angle. These braking requirement signals are compared to a signal from a third measuring device in order to monitor the braking requirement measuring devices.

  • Patent number: 6626271
    Abstract: The present invention relates to an electrically operable brake system and a method for its actuation. The brake system and the method are characterized in that the service brake system can be activated by two brake operating devices which are operable by the driver independently of each other. The main advantage which results is that upon failure of a brake operating device which is e.g. configured as a brake pedal module, braking of the vehicle can be achieved by means of the service brake system by way of the second brake operating device. The additional functions intended for the service brake system, such as ABS, TCS, driving dynamics control, brake assist system, etc., may then be implemented, if so desired. The redundant design of the actuation for the service brake permits achieving a high degree of operational safety because full braking functions can be maintained even in case of emergency braking.

  • Patent number: 6550871
    Abstract: A method and system for controlling a brake for motor vehicles. The present invention relates to a method as well as a system for controlling a brake for motor vehicles, which can be electromechanically actuated by means of an actuator, consisting of an electric motor as well as a drive mechanism positioned downstream of the electric motor. In order to be able to increase motor speed under certain operating conditions, i.e. according to demand, without reducing the available torque, the invention provides for the slope of the speed-torque characteristic curve of the electric motor (4) to be modified by weakening components of the electromagnetic field of said electric motor (4), which affect the dynamics of same, in such a way that a higher speed (&ohgr;′1) is obtained at the same torque (M1).

  • Patent number: 6345225
    Abstract: This invention relates to an electromechanical brake system, in particular for automotive vehicles, which includes a pedal module and at least two brake modules. Further, a central module may be provided. Connection between the aforementioned modules can be made by a data bus. The data bus is provided redundantly. In one embodiment, the central module can evaluate signals of a sensor system and examine them for their errors. Further, the central module can emit a corresponding nominal braking value which then is emitted to the brake modules. Thereupon, the brake modules determine appropriate actuating signals for the actuators which interact with the wheels in order to realize the driver's braking intention.

  • Patent number: 6318819
    Abstract: Electronic brake systems are functionally split-up safety-critical real-time systems which are subject to high standards with regard to error detection and error handling. This invention describes a method and corresponding device for error handling in such systems which permits only a few defined system conditions, inclusive of a pre-check, with the transition from one system condition to the next condition only being possible if certain defined events take place.

  • Patent number: 6317675
    Abstract: An electromechanical brake system, particularly for motor vehicles, with a pedal simulator and brake modules is disclosed. A central module is also provided. The connection between the aforesaid modules can be provided by a data bus. The central module evaluates the braking request signals from a sensor device and checks them for errors. Also, a central module supplies and appropriate desired braking value based on the braking request and possibly higher functions such as ABS or ASR. The desired braking value is then conveyed on to the brake module, which then determines the corresponding control signals for the actuators, which interact with the wheels in order to brake the vehicle as the driver requires.
