In a method and a driver assistance system for representing vehicle surroundings of a vehicle having a sensor system for detecting the environment, a boundary of a traffic lane or driving path on which the vehicle is currently being driven is represented by position points that each have a predefined set of attributes especially including a width attribute indicating a lateral width of an unobstructed area available as a maneuvering space on an opposite side of the respective position point.

Method for representing vehicle surroundings

A method for assisting a vehicle driver, wherein a sensor for covering the surroundings covers a pavement in front of the vehicle in order to determine a virtual vehicle corridor for a road vehicle in a complex traffic situation and the virtual vehicle corridor is determined depending on identified traffic lines and raised pavement boundaries.

Method for determining a virtual vehicle corridor

Disclosed is a method for assisting an operator of a vehicle in adjusting a nominal steering angle at steerable wheels of the vehicle for the vehicle stabilization. An additional steering torque is applied to the steering line of the vehicle, which is determined dependent on a difference between a nominal steering angle and an instantaneous steering angle. The method is characterized in that a value of a load moment acting on the steering line of the vehicle is estimated, and that the additional steering torque is established dependent on the estimated value for the load moment.

In a method and a device for assisting an operator of a vehicle in the vehicle stabilization, an additional steering torque is applied to the steering line of the vehicle. The method manifests itself by the feature that a first component of the additional steering torque is determined depending on a steering angle difference between an instantaneous steering angle at steerable wheels of the vehicle and a nominal steering angle, and the steering angle difference is determined depending on a difference between an instantaneous value of a yaw rate of the vehicle and a value of a reference yaw rate, and with the value of the reference yaw rate being established in a vehicle model by way of a value of at least one variable predefined by the driver. The device implements the method.

The invention proposes a process for determining the driving torque of a vehicle as it is starting. This process and device uses a model of the idling properties of the engine, a comparing element for the output values of the model and corresponding measured values or values derived therefrom, and a determining element for determining the driving torque of the vehicle according to the results of the comparison. Furthermore, the invention discloses a process and device for determining an externally generated variable that drives or brakes the vehicle as well as for supporting uphill starting. In addition, processes and devices for determining externally generated variables/torques as well as for supporting uphill starting are disclosed.

Method for adjusting a brake system of a vehicle

The invention concerns a process for shortening the braking distance of a vehicle equipped with a brake servo unit which during a standard braking action is only triggered by the brake pedal pressure caused by the driver and in case of a critical driving situation is so triggered by a control device that in comparison to the standard braking action an increased amplification factor is set at the brake servo unit. The invention distinguishes itself by the fact that a danger potential is determined, stating the probability that the vehicle to be braked will be involved in an accident and that the increase of the amplification factor is controlled in accordance with the danger potential.

Method for reducing braking distance

A device for determining set values for the braking forces or braking torque of the brake system of a vehicle comprising an electric drive, a friction brake applying braking forces to all wheels according to corresponding set values, an electrodynamic regenerative brake applying braking forces to at least one axle according to corresponding set values, and an element for determining the set values according to the desired vehicle deceleration, wherein such element for determining the set values according to the deceleration requirement either makes the set value for the electric regenerative as large as possible or sets the set values for the electrodynamic regenerative brake and for the friction brake primarily according to criteria concerning the distribution of the braking forces on the axles. In addition, an element for correcting a set value for the friction brake, preferably at the front axle according to the dynamic behavior of the electrodynamic regenerative brake may be provided.

The present invention relates to a maneuvering assistance system for automotive vehicles and a method of maneuvering automotive vehicles which permit a simple and safe maneuvering of the automotive vehicle particularly during a parking procedure. The present invention is especially advantageous when the automotive vehicle needs to be maneuvered, for example, on a steep positive or negative gradient. According to the present invention, a preselected or adjustable maneuvering speed is chosen such that the driver is not surprised by unwanted reactions of the automotive vehicle. The present invention especially comprises an accelerator pedal sensor &lsqb;(,)&rsqb; for detecting an accelerator pedal position &lsqb;(&agr;)&rsqb; and a device for determining a speed &lsqb;(v,)&rsqb; of the vehicle. By using values pertaining to the accelerator pedal position &lsqb;(&agr;)&rsqb;, to the accelerator pedal depression speed &lsqb;({dot over (&agr;)})&rsqb;, and the vehicle speed &lsqb;(v,)&rsqb;, a control unit &lsqb;(,)&rsqb; determines whether the vehicle is in a maneuvering or parking condition, in order to accordingly actuate an engine &lsqb;(,)&rsqb; or a brake control system &lsqb;(,)&rsqb; so that the vehicle &lsqb;(,)&rsqb; is moved at a desired maneuvering speed.

Method and device for maneuvering motor vehicles

A brake power assist unit for motor vehicles, the control valve of which can be electrically actuated by means of an electromagnet which actuates a third sealing seat that allows ventilation of the operating chamber. In order to stabilize the characteristic of the load system formed by the armature of the electromagnet, a sleeve that carries the third sealing seat and the valve body of the control valve by means of constructive modifications of the control valve of the externally actuated brake power assist unit, in particular, during the pressure reduction phase, the invention proposes means that allow a controlled pneumatic pressure compensation between the operating chamber and the vacuum chamber or a reduction in the force to be generated by the electromagnet during the pressure reduction phase, i.e., during the return movement of the third sealing seat from the valve body.

Power brake for motor vehicles

A brake system for motor vehicles with an adjustable pneumatic brake force booster includes a control valve which can be actuated by an electromagnet independently of the driver's actions. A brake pressure controller generates signals which serve to actuate the electromagnet. In order to be able to implement a quick-action, low-noise pressure regulating system at low cost, the brake pressure controller (,) is formed by connecting in parallel an electromagnetic control circuit (,) that processes the nominal brake pressure signal (P,) into a first current value (I,) and a regulating circuit (,) that processes a control difference (&Dgr;P) formed from the nominal brake pressure signal (P,) and the actual pressure signal (P,) into a second current value I,, with the output variable (I,) of the brake pressure controller (,) being formed by adding together the two current values (I,, I,).
