Abstract

Abstract A method and a device for determining a future travel-course progression or travel-course range of a vehicle whose traveling speed is controllable as a function of a distance to preceding-traveling vehicles, the future course range being determined at least on the basis of a course progression of one preceding-traveling vehicle. Moreover, a lateral offset is determined for all detected preceding-traveling vehicles. The determined future course range is limited on the basis of detected stationary objects.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 164 words
A method for determining a future travel-course range of a first vehicle equipped with a proximity sensor, comprising the steps of: using the proximity sensor, determining at least two relative positions of one preceding-traveling vehicle with respect to the first vehicle; ascertaining lateral offsets between the preceding-traveling vehicle and the first vehicle on the basis of the at least two relative positions; ascertaining a future course range of the first vehicle as a function of a course progression of the preceding-traveling vehicle; forming the course progression of the preceding-traveling vehicle from the at least two determined relative positions of the preceding-traveling vehicle; forming reference points as a function of lateral offsets and of the course progression of the preceding-traveling vehicle; determining a function, corresponding to a future course progression of the first vehicle, which includes essentially all of the reference points; and expanding the future course progression of the first vehicle by a predetermined width, yielding the future course range of the first vehicle.
Claim 2
Independent Claim 164 words
A method for determining a future travel-course range of a first vehicle equipped with a proximity sensor, comprising the steps of: using the proximity sensor, determining at least two relative positions of one preceding-traveling vehicle with respect to the first vehicle; ascertaining lateral offsets between the preceding-traveling vehicle and the first vehicle on the basis of the at least two relative positions; ascertaining a future course range of the first vehicle as a function of a course progression of the preceding-traveling vehicle; forming the course progression of the preceding-traveling vehicle from the at least two determined relative positions of the preceding-traveling vehicle; forming reference points as a function of lateral offsets and of the course progression of the preceding-traveling vehicle; determining a function, corresponding to a future course progression of the first vehicle, which includes essentially all of the reference points; and expanding the future course progression of the first vehicle by a predetermined width, yielding the future course range of the first vehicle.
Claim 3
Dependent Claim 68 words
The method according to claim 1 , further comprising the steps of: determining a relative position of the preceding-traveling vehicle with respect to the first vehicle; based on the relative position, determining a lateral offset between the preceding-traveling vehicle and the first vehicle; and determining the future course range of the first vehicle as a function of the lateral offset and the course progression of the preceding-traveling vehicle.
Claim 4
Dependent Claim 31 words
The method according to claim 2 , further comprising the steps of: re-determining the lateral offset at predetermined instants; and assuming that the lateral offset is constant between the predetermined instants.
Claim 5
Dependent Claim 59 words
The method according to claim 1 , further comprising the steps of: determining the future course range on the basis of course progressions of a plurality of preceding-traveling vehicles; and isolating a travel-lane change of an individual preceding-traveling vehicle by one of a comparison, a correlation and an average of the course progressions of the plurality of preceding-traveling vehicles.
Claim 6
Dependent Claim 83 words
The method according to claim 1 , further comprising the steps of: determining at least one further future course range of the first vehicle on the basis of at least one of a steering angle, a steering-wheel angle, a yaw rate, a difference of wheel speeds, a transverse acceleration, stationary objects, and oncoming vehicles detected by the proximity sensor; and ascertaining a verified future course range as a function of the future course range and the at least one further future course range.
Claim 7
Dependent Claim 34 words
The method according to claim 1 , further comprising the steps of: limiting the future course range on the basis of positions of at least one of: detected stationary objects and detected oncoming vehicles.
Claim 8
Independent Claim 177 words
A device comprising: a proximity sensor for determining at least two relative positions of one preceding-traveling vehicle with respect to a first vehicle; an evaluation device for ascertaining at least an angle, a distance and a speed of the one preceding-traveling vehicle; means for ascertaining lateral offsets between the preceding-traveling vehicle and the first vehicle on the basis of the at least two relative positions; means for ascertaining a future course range of the first vehicle as a function of a course progression of the preceding-traveling vehicle; means for forming the course progression of the preceding-traveling vehicle from the at least two determined relative positions of the preceding-traveling vehicle; means for forming reference points as a function of lateral offsets and of the course progression of the preceding-traveling vehicle; means for determining a function, corresponding to a future course progression of the first vehicle, which includes essentially all of the reference points; and means for expanding the future course progression of the first vehicle by a predetermined width, yielding the future course range of the first vehicle.
Claim 9
Independent Claim 177 words
A device comprising: a proximity sensor for determining at least two relative positions of one preceding-traveling vehicle with respect to a first vehicle; an evaluation device for ascertaining at least an angle, a distance and a speed of the one preceding-traveling vehicle; means for ascertaining lateral offsets between the preceding-traveling vehicle and the first vehicle on the basis of the at least two relative positions; means for ascertaining a future course range of the first vehicle as a function of a course progression of the preceding-traveling vehicle; means for forming the course progression of the preceding-traveling vehicle from the at least two determined relative positions of the preceding-traveling vehicle; means for forming reference points as a function of lateral offsets and of the course progression of the preceding-traveling vehicle; means for determining a function, corresponding to a future course progression of the first vehicle, which includes essentially all of the reference points; and means for expanding the future course progression of the first vehicle by a predetermined width, yielding the future course range of the first vehicle.
