Abstract
A pre-crash sensing system is coupled to a countermeasure system that has at least a first countermeasure and a second countermeasure. The pre-crash sensing system has a vision system (26) that generates an object size signal and an object distance signal. A controller (12) is coupled to the vision system (26) and deploys either the first countermeasure or first and second countermeasures in response to the object distance and object size.
Claims17
A pre-crash sensing system coupled to a countermeasure system having at least a first countermeasure and a second countermeasure comprising:
- a vision system generating an object size signal and an object distance signal;
- and
- a controller coupled to said vision system for deploying either said first countermeasure or said first and second countermeasures in response to said object distance signal and said object size signal.
A method for operating a pre-crash sensing system for an automotive vehicle having a countermeasure system, said method comprising:
- establishing a decision zone relative to the vehicle;
- detecting an object within the decision zone using a vision system;
- determining an object distance and relative velocity using a vision system;
- determining an object size;
- and
- activating the countermeasure system in response to the object size and relative velocity.
