A side impact object sensing system for a vehicle includes a single radar sensor mounted on each side of the vehicle, each sensor generating a range and range-rate value for a detected target object, and a controller coupled to each radar sensor. The controller calculates an estimated target object speed, an angle of the target object line of travel with respect to the respective sensor line of sight, and a shortest distance value from the respective sensor to the target object line of travel, and compares the shortest distance value and a change in the angle value to respective threshold values for potential collision threat assessment.

A vision-based object detection decision-making system (10) for a vehicle (12) includes multiple vision sensing systems (14) that have vision receivers (20) and that generate an object detection signal. A controller (16) includes a plurality of sensing system aid modules (18) that correspond to each of the vision sensing systems (14). The controller (16) operates the sensing system aid modules (18) in response to a vehicle parameter and generates a safety system signal in response to the object detection signal. The sensing system aid modules (18) have associated operating modes and operate the vision sensing systems (14) in the operating modes in response to the vehicle parameter.
摘要:
A pre-crash assessment system includes a host vehicle in motion. A remote sensor, status monitoring sensors, and safety device actuators are coupled to the host object. The remote sensor detects target object dynamics. The status monitoring sensors detect host object dynamics. The safety device actuators activate safety devices. A threshold for each safety device actuator is defined by a safety device activation specification. A safety device controller generates tracking signals based on host object and target object dynamics by generalized conic curve fitting techniques. The safety device controller also estimates future positions of the host and target objects, and estimates whether the potential for crash between the host and target objects is within the threshold criteria for specific safety device actuation.
摘要:
A pre-crash sensing system (10) for a source vehicle (50) having a source vehicle length and a source vehicle width that is coupled to a countermeasure system (30) is described. The system includes an object sensor (17) generating object distance signal, object relative velocity signal and an object classification signal. A controller (12) is coupled to the object sensor (17). The controller determines a danger zone (52) based on the source vehicle length, source vehicle width, object length and object width. The controller determines a source vehicle time interval corresponding to the time the source vehicle is within the danger zone. Controller (12) determines an object time interval corresponding to the time the object is within the danger zone and when the source vehicle time interval corresponds with the target vehicle time interval. The controller activates the countermeasure system (30) when the source vehicle time interval coincides with the target vehicle time interval.

Traffic density may be estimated by increasing a value of a parameter if an object enters a predefined zone on a side of the vehicle and decreasing the value of the parameter after an object exits the predefined zone such that the value of the parameter increases as traffic in a vicinity of the vehicle increases and decreases as traffic in the vicinity of the vehicle decreases.

摘要:
An advertisement message system includes a plurality of modules providing current state values, including at least a GPS location proximity value, a workload value, and an advertisement optimization value. The system also includes a processor configured to receive state values from the plurality of modules. The system further includes an advertisement database including a plurality of advertisements. The processor is configured to determine that ad delivery is appropriate and to select an ad with a likelihood of driver response above a certain threshold. The selection is based at least in part on a currently received GPS location proximity value, workload value and advertisement optimization value, and to deliver the advertisement through a vehicle output.
