System for influencing the speed of a motor vehicle
First Claim
1. A system for evaluating a traffic environment of a motor vehicle and for influencing a speed of the motor vehicle in its own traffic lane, comprising:
- a signal transmitter that is configured to produce a signal characteristic of a desired speed of the motor vehicle;
a signal transmitter that is configured to produce a signal characteristic of a yaw of the motor vehicle about its vertical axis;
a signal transmitter that is configured to produce a signal characteristic of article situated, in a direction of travel of the motor vehicle, in front of the motor vehicle in terms of their spacing and orientation relative to the motor vehicle and which represents at least one of;
(i) a speed relative to the speed of the motor vehicle;
(ii) a spacing relative to the motor vehicle; and
(iii) an angular offset or the cross track distance relative to the vehicle longitudinal axis of the motor vehicle;
a signal transmitter that is configured to produce a signal characteristic of the speed of at least one wheel of the motor vehicle;
an electronic control unit (ECU) connected to the signal transmitters and that is configured to generate output signals in response to the desired speed signal, the yaw signal, and the article signal, in which in the electronic control unit (ECU) is configured to modify a simulated width of the motor vehicle traffic lane in dependence upon the distance of the articles detected in front of the motor vehicle from the motor vehicle, wherein the simulated width in a close range in front of the motor vehicle and in a remote range in front of the motor vehicle is smaller than in a medium range in front of the motor vehicle; and
a control device connected to the electronic control unit (ECU) and that is configured to influence the actual speed of the motor vehicle in response to the output signal.

Abstract
System for evaluating the traffic environment of a motor vehicle and for influencing the speed of the motor vehicle in its own traffic lane, comprising an electronic control unit (ECU), which is connected to a signal transmitter that produces a signal characteristic of the desired speed of the motor vehicle, a signal transmitter that produces a signal characteristic of the yaw of the motor vehicle about its vertical axis, a signal transmitter that produces a signal characteristic of the articles situated, in the direction of travel of the motor vehicle, in front of the motor vehicle in terms of their spacing and orientation relative to the motor vehicle and which reproduces the speed relative to the speed of the system motor vehicle and/or the spacing relative to the system motor vehicle and/or the angular offset or the cross track distance relative to the vehicle longitudinal axis of the system motor vehicle, and a signal transmitter that produces a signal characteristic of the speed of at least one wheel of the motor vehicle, and which is connected to at least one control device, which influences the performance of the motor vehicle, in order to supply said device with output signals derived from the performance of the motor vehicle situated in front of the system motor vehicle, in which in the electronic control unit (ECU) the width of the system motor vehicle traffic lane is modified in dependence upon the distance of articles detected in the space in front of the system motor vehicle from the system motor vehicle, wherein the width in the close range and in the remote range is smaller than in the medium range.

8. A system for evaluating a traffic environment of a motor vehicle and for influencing a speed of the motor vehicle in the motor vehicle'"'"'s traffic lane, comprising:
-
a first signal transmitter that produces a signal characteristic of a desired speed of the motor vehicle; a second signal transmitter that produces a signal characteristic of a yaw of the motor vehicle about its vertical axis; a third signal transmitter that produces a signal characteristic of an article situated in front of the motor vehicle in a direction of travel of the motor vehicle in terms of a spacing and orientation of the article relative to the motor vehicle; a fourth signal transmitter that produces a signal characteristic of the speed of at least one wheel of the motor vehicle; an electronic control unit (ECU) which receives the signals produced by the first, second, third, and fourth signal transmitters, and which modifies a simulated width of the motor vehicle traffic lane in dependence upon the distance between the motor vehicle and the article detected in a space in front of the motor vehicle such that the simulated width in a close range in front of the motor vehicle and in a remote range in front of the motor vehicle is smaller than in a medium range in front of the motor vehicle, the electronic control unit (ECU) generating an output signal based upon the performance of the motor vehicle and the detection of the article situated in front of the motor vehicle; and at least one control device which influences the performance of the motor vehicle based at least in part upon the output signal of the electronic control unit (ECU). - View Dependent Claims (9, 10)
