摘要:
The invention relates to a deceleration warning device for reducing rear-end collisions in road traffic, comprising: means (1) for detecting a longitudinal acceleration value a; a control device (3a; 3b; 3c; 3d) which is designed to receive the longitudinal acceleration value a at one of its inputs and to calculate an acceleration limit value upon exceeding of which a warning signal is emitted, the calculation of the acceleration limit value incorporating input parameters P, a filter device (2a; 2b) being interposed between the means (1) for detecting a longitudinal acceleration value and the control device, and display means for displaying an alarm state when the control device emits a warning signal.
摘要:
A deceleration warning device for reducing rear-end collisions in road traffic includes a sensor for detecting a longitudinal acceleration value, a control device receiving the longitudinal acceleration value, determining an acceleration limit value, and generating a warning signal if the longitudinal acceleration value exceeds the acceleration limit value, and a rear lighting display for displaying an alarm state when the control device emits a warning signal. Determination of the acceleration limit value is based upon a plurality of signals including an anti-lock braking system (ABS) signal and a brake pedal position signal. The control device is operable in one of three levels depending upon a detected quality of the signals.

The invention relates to a method for compensating for drive influences of a drive train of a motor vehicle on its steering system, said motor vehicle having an electric power steering system. A drive train simulation model which is integrated into the motor vehicle and permanently activated is used to determine disturbance variables from a driven behavior so that a compensation torque which counteracts the disturbance variables is generated for the power steering system.

A method and apparatus for determining whether to alert a driver of a vehicle to the presence of a traffic sign in the vehicle's driving environment. An optical system on-board the vehicle detects the traffic sign and determine information related to the sign. Driving maneuvers carried out by the vehicle are monitored to determine driving situation information. The driving situation information and the traffic sign information are used to determine a probability that the sign is pertinent for the vehicle under the current driving conditions. If the probability is above a threshold, the driver is alerted to the traffic sign. The probability of the pertinence of the traffic sign may be further determined on the basis of lane-specific information such as vehicle position relative to a freeway exit ramp start or end, or performance of a lane change by the vehicle.
摘要:
A method and device for the detection and compensation of periodic disturbances in the steering device of a motor vehicle in which a speed-dependent target frequency is determined, and that a Fourier analysis of a time profile of the steering force and/or of the steering torque is carried out for the determined target frequency or a multiple of the target frequency. The method and device also include obtaining amplitudes that are plotted as a function of the vehicle speed, and a model function may be adapted to the curve, the adapted parameter of which model function then constitutes a robust measure for the disturbances. As a function of the parameter, the disturbances can then be suppressed by means of targeted action on a power assistance arrangement of the steering.

Various embodiments include a system and a method for recognizing road signs. An image of a road sign may be captured by least one image sensor. A vehicle computer may receive the image data representing one or more road signs along a route and display one or more images of the road sign based on the image data. The display may be capable of presenting one or more status of the road sign based on one or more travel states for the vehicle. These travel states may include at least one of an amount of elapsed travel time, distance travelled, or speed.

The invention relates to a method for reducing a risk of or avoiding a roll-over event of a vehicle, having means of an electronic controllable steering system and an electronic control unit. The electronic control unit identifies the occurrence of the roll-over risk, such that control means generate a signal in order to steer the road wheels more into the direction in which the vehicle is tending to roll-over.
