The invention relates to a method for the generation of control variables (am, ab), for the guidance of a vehicle, depending on input parameters (V, el, ek, di vri, Fi), which represent the traffic situation and depending on dynamically changing parameters, characterised in that a single evaluation parameter (g) is generated from a set of several input parameters and that several of the parameters are determined by means of the same evaluation parameter.

The invention relates to a method for mismatch detection in a vehicle-sensor system, wherein a signal is transmitted and wherein signals reflected by a standing object are received. The transmitted and received signals are used to determine a relative angle and a relative distance or a longitudinal and a transverse mismatch between a detected object and a reference axis of a vehicle and a relative speed between a detected object and a vehicle. The relative angle, the relative distance and the vehicle speed or a longitudinal mismatch, transverse mismatch and vehicle speed are used to calculate a correction value for the relative angle.

The invention relates to a method and device for determining the future course of a first vehicle (700) that is fitted with a distance sensor, whereby the at least relative positions (707, 708) of at least one travelling vehicle ahead (702, 703) are determined with respect to the first vehicle (700) at a given or selectable moment in time with the aid of said distance sensor. The at least relative positions (707, 708) thus determined are stored in at least one memory. These relative positions (707, 708) that are stored in said memory are used to create a trajectory (709, 710) for the vehicle ahead (702, 703). The future course of the first vehicle (700) is determined at least by means of the trajectory (709, 710) of the travelling vehicle ahead (702, 703). The trajectory (709) of the travelling vehicle ahead (702, 703) is projected towards the position of the first vehicle (700).

The invention relates to a speed regulator for motor vehicles, which comprises an input device (12, 14, 18) for the driver to input the desired speed Vset, and a plurality of operating modes (ACC, S & R) that can be activated in different speed ranges and that differ in their functional scope. The speed regulator is characterized by a decision unit (24) that automatically switches the operating mode based on the actual speed V of the vehicle.

The invention relates to a speed control for motor vehicles, comprising a sensor device for measuring operational parameters of the vehicle and for measuring the distance to a target object in front of the vehicle, a control device for controlling speed or accelerating the vehicle in accordance with the measured operational parameters and distance data, a switch-off command input device (S2) for switching off the control and a switch-off function for switching off (S4) the control in accordance with other commands (S6, S7, S8, S9) of the driver. The control is provided with a stop function for automatically decelerating the vehicle to a standstill, the switch-off command input device (S2) being ineffective when the stop function is active (S3) and the vehicle is at a standstill (S5).

The invention concerns a device for longitudinally guiding a motor vehicle (10), comprising a speed sensor (12) for measuring the vehicle running speed, a distance sensor (14) for measuring the distance relative to an obstacle located more or less in front of the vehicle (10), and a regulator acting on the driving system and the braking system (20, 22) of the vehicle and adjusting the running speed, in a closed regulating loop, as the case may be, on the basis of the distance relative to the obstacle, insofar as the running speed is greater than a specific speed. The invention is characterized in that it comprises a control device (18) which operates so as to control the driving and braking systems (20, 22) in case the running speeds are lower than the threshold speed.

Described is a process for determining the speed of a vehicle with an antilocking or antiskid system, in which the wheel speeds vRi and the brake pressures Pi or brake/drive torques MBi are measured at time intervals T. From the last set of values measured, i.e. vRi(k) and MBi(k) at time k, and the stored values of vRi(k-1) measured at the previous time interval, a correction factor Ko is calculated, using a given relationship, and this factor used to correct the vehicle speed vF(k-1) determined from the values measured at the previous time interval.
摘要:
Selon un procédé de détermination du couple de freinage au niveau des roues d'un véhicule que l'on freine, on mesure en continu la pression de freinage Pi qui s'exerce sur les roues pendant un intervalle de freinage (t1 à t2), et on mesure la vitesse des roues VRi au début (VRi(t1)) et à la fin (VRi(t2)) dudit intervalle. Sur la base de ces valeurs de mesure, on peut déterminer selon une relation donnée le facteur de proportionnalité CP entre le couple et la pression de freinage; on en déduit également de manière aisée les couples de freinage MBi au niveau des roues (MBi = CP.Pi).

A distance control system for motor vehicles, comprising a sensor system (12) for detecting data on a target object (18) and data on an actual vehicle (10), an actuator system (16) for controlling the longitudinal movement of the vehicle (10), a controller (14) which intervenes with the actuator system (16) within specific limits of intervention (Lim1, Lim2) in order to maintain a defined control destination with regard to the distance to the target object (18), and an output device (20) for outputting a take-over request (FUA) to the driver if the control destination cannot be maintained. The invention is characterized by a prediction system (22) which can predict a conflict situation in which the control destination cannot be maintained and which can trigger a take-over request (FUA) before the conflict situation occurs.
