Abstract
An object classification method in which a vehicle moves toward an object includes: (a) ascertaining a first characteristic quantity from the variation of a first signal received by a distance-measuring sensor; (b) ascertaining an additional characteristic quantity from the variation of a second signal received by the distance-measuring sensor; (c) ascertaining a distance traveled by the vehicle between step (a) and step (b); (d) ascertaining a predictive quantity associated with the distance ascertained in step (c); (e) comparing the predictive quantity with the additional characteristic quantity; and (f) generating an object classification signal.
Claims11
An object classification method for classifying an object during a parking operation involving movement of a vehicle toward the object, comprising:
- (a) ascertaining a first characteristic quantity from a variation of a first signal received by a distance-measuring sensor in the vehicle;
- (b) ascertaining a second characteristic quantity from a variation of a second signal received by the distance-measuring sensor;
- (c) ascertaining a distance traveled by the vehicle between step (a) and step (b);
- (d) ascertaining a predictive quantity from the ascertained first characteristic quantity, wherein the predictive quantity is associated with the distance ascertained in step (c);
- (e) comparing the predictive quantity with the second characteristic quantity ascertained in step (b);
- and
- (f) generating an object classification signal associated with the object, wherein the object classification signal has a first state if the predictive quantity is less than the second characteristic quantity or a second state if the predictive quantity is greater than or equal to the second characteristic quantity.
A non-transitory computer-readable storage medium storing a computer program having program codes which, when executed on a computer, control a method of classifying an object during a parking operation involving movement of a vehicle toward the object, the method comprising:
- (a) ascertaining a first characteristic quantity from a variation of a first signal received by a distance-measuring sensor in the vehicle;
- (b) ascertaining a second characteristic quantity from a variation of a second signal received by the distance-measuring sensor;
- (c) ascertaining a distance traveled by the vehicle between step (a) and step (b);
- (d) ascertaining a predictive quantity from the ascertained first characteristic quantity, wherein the predictive quantity is associated with the distance ascertained in step (c);
- (e) comparing the predictive quantity with the second characteristic quantity ascertained in step (b);
- and
- (f) generating an object classification signal associated with the object, wherein the object classification signal has a first state if the predictive quantity is less than the second characteristic quantity or a second state if the predictive quantity is greater than or equal to the second characteristic quantity.
A parking assistance system for aiding a parking operation of a vehicle involving movement of the vehicle toward an object, comprising:
- a distance-measuring sensor configured to periodically transmit a signal from the vehicle toward the object and receive a reflected signal from the object;
- and
- a program-controlled device configured to:
- ascertain a first characteristic quantity from a variation of a first signal received by the distance-measuring sensor;
- ascertains a second characteristic quantity from a variation of a second signal received by the distance-measuring sensor;
- ascertain a distance traveled by the vehicle between the points in time when the first and the second characteristic quantities are ascertained;
- ascertain a predictive quantity from the first ascertained characteristic quantity, wherein the predictive quantity is associated with the ascertained distance traveled by the vehicle;
- compares the predictive quantity with the second characteristic quantity;
- and
- generate an object classification signal associated with the object, wherein the object classification signal has a first state if the predictive quantity is less than the second characteristic quantity or a second state if the predictive quantity is greater than or equal to the second characteristic quantity.
