摘要:
A process for increasing the stability of a vehicle upon acceleration on a roadway with a non-homogenous coefficient of friction, whereby a drive wheel is acted on by a braking force on a side with a low coefficient of friction by means of a drive slip regulation. A value (pASR) is determined which corresponds to the braking force (FB,ASR) set by the drive slip regulation (ASR). The value determined (pASR) is used for the determination of a disrupting yaw momentum (MZ), and a control portion (ΔδZ) of a supplemental steering angle (Δδ) is determined in dependence on the disrupting yaw momentum (MZ). An apparatus for the implementation of the process is also provided.

The invention relates to a method for actuating an electromechanical parking brake device for a brake that can be actuated by means of an electromechanical actuator, in which the actuator is comprised of an electric motor and of a reduction gear connected downstream of the electric motor and being provided for converting a rotational motion into a translatory motion, the electromechanical parking brake being provided in the form of a locking mechanism which can prevent the rotational motion of the actuator in the direction of release and which can be released again by further application. In order to guarantee that the electromechanical parking brake device works reliably in all operating states without using a tension force sensor, the invention discloses determining and storing, during the actuation of a parking brake device, a mean value of the torque of the electric motor necessary for generating the application force of the brake corresponding to the parking brake actuation and to simultaneously determine the actuator position and to actuate the electric motor at later points of time in such a way that it generates this torque multiplied by a correction factor kη=>1 so that the exerted tension force is maintained or increased.

In order to achieve an optimal pressure build-up function in an anti-lock braking control system for automotive vehicles and to maintain the pressure at the optimal point for long periods of time and thus achieve better brake deceleration with greater stability of travel and greater comfort than with conventional ABS control systems, the anti-lock braking control system includes, in addition to the ABS controller and monitoring circuit (3), a pressure function generator (4) which, for each wheel, intermediately stores an intermediate brake pressure value whenever wheel overbraking has been noted. Then, in the pressure build-up phase, the pressure function generator (4) gives off a signal to the pressure modulator in order to increase the wheel brake pressure in accordance with an exponential function.

An antilock brake system for motorcycles, which ensures that after travel on a curve has been definitely recognized, a modified antilock brake system is activated which adjusts itself dynamically to the degree of tilt reached. The antilock brake system monitors travel on the curve and the degree of tilt with two acceleration sensors and supplements the monitoring circuit by an auxiliary circuit which causes the ABS control, through control signals, to maintain the braking pressure on the front wheel even before the anticipated lockup pressure is reached.

A method for operating a braking system in a motor vehicle having at least two wheel brakes (54, 56), each of which can be activated by an electromechanical actuator of the self-locking type. Each wheel brake having a locking device for implementing a parking brake functionality, in which the locking device and respective electromechanical actuator is actuated and locked by the locking device when a parking brake function is carried out. A first method step is carried out in which the at least two actuators are actuated in succession and a second method step is carried out in which it is checked whether the at least two actuators have achieved respectively predefined brake application force. In the event of the at least two actuators having achieved the respectively predefined brake application force, the at least two actuators are locked in a third method step.

The invention relates to a method for controlling and adjusting digitally or analogically adjustable shock absorbers, preferably in a two-axle road vehicle where the shock absorbers are controlled according to the situation by means of a control signal such that the road performance of the vehicle is improved when understeering or oversteering occurs. To improve the dynamics of movement of a vehicle in any driving situation, it is proposed according to the invention, to determine phase magnitudes, from which the phases of the control signals is calculated, and, in the case of a driving situation with a tendency to sway, to determine a moment in time, as a function of at least the magnitudes which describe the rotation of the vehicle about the vertical axis, when a correct phase control of the shock absorbers of the vehicle is carried out to increase the steerability when understeering occurs and to increase the driving stability when oversteering occurs.
