Abstract
A control system for an automotive vehicle (50) has a radar or lidar system (22) used to generate a remote object signal. A vision system (26) generates an object size signal. A controller (12) is coupled to the radar (22) and the vision system (26). The controller activates a first countermeasure or the first and a second countermeasure in response to the object distance and object size signals.
Claims20
A pre-crash sensing system for an automotive vehicle coupled to a countermeasure system having at least a first countermeasure and a second countermeasure comprising:
- a radar or lidar unit generating an object distance signal and object relative velocity signal;
- a vision system generating an object size signal;
- and
- a controller coupled to said radar unit and said vision unit for activating either said first countermeasure or the first and the second countermeasures in response to said object distance, relative velocity and said object size signals.
A pre-crash sensing system coupled to a countermeasure system having a first countermeasure and a second countermeasure, said pre-crash sensing system comprising:
- a first sensor generating an object distance signal and relative velocity signal for an object present in a predefined decision zone;
- a second sensor generating an object size signal;
- and
- a controller coupled to said first sensor and said second sensor for activating either said first countermeasure or said first and said second countermeasures in response to said object distance, said object relative velocity and said object size signals.
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;
- determining an object distance and relative velocity;
- determining an object size;
- and
- activating the countermeasure system in response to the object size and relative velocity.
