Abstract
An onboard perception system of a vehicle is contemplated. The system may include a state assessment unit adapted to at least assess a state of a first external object located in a vicinity of the vehicle hosting the onboard perception system, at least a first sensor assembly for assessing sound information, and an evaluation means adapted to evaluate a change in the state of the first external object by using the assessed sound information.
Claims15
A method for evaluating a reason of a detected change in dynamic state of an object located in a vicinity of a vehicle hosting an onboard perception system, said method comprising:
- assessing audible sound information originating from a source other than a collision involving said host vehicle using a sound sensor assembly;
- analyzing said sound information to evaluate the reason of said detected change in dynamic state of the object;
- and
- controlling an action of the vehicle based on the evaluation of said reason of said detected change in state.
An onboard perception system for a vehicle comprising:
- a sensor assembly assessing a dynamic state of an object in a vicinity of the vehicle;
- a sound sensor assembly receiving and assessing audible sound information originating from a source other than a collision involving the vehicle;
- an evaluation unit detecting a change in the dynamic state of the object and analyzing the sound information in combination with information from the sensor assembly to assess a reason for the change in the dynamic state;
- and
- wherein an action of the vehicle is controlled based on the assessed reason for the change in the dynamic state of the object.
A method for operating a safety system of a vehicle comprising:
- operating a sensor assembly to assess a dynamic state of an object in a vicinity of the vehicle;
- detecting a change in the dynamic state of the object;
- operating a sound sensor assembly to receive and assess audible sound information originating from a source other than a collision involving the vehicle;
- analyzing the sound information in combination with information from the sensor assembly to assess a reason for the change in the dynamic state;
- and
- controlling an action of the vehicle based on the assessed reason for the change in the dynamic state.
