Context-aware threat response arbitration

Abstract

A method for prioritizing potential threats identified by vehicle active safety systems. The method includes providing context information including map information, vehicle position information, traffic assessment information, road condition information, weather condition information, and vehicle state information. The method calculates a system context value for each active safety system using the context information. Each active safety system provides a system threat level value, a system braking value, a system steering value, and a system throttle value. The method calculates an overall threat level value using all of the system context values and all of the system threat level values. The method then provides a braking request value to vehicle brakes based on all of the system braking values, a throttle request value to a vehicle throttle based on all of the system throttle values, and a steering request value to vehicle steering based on all of the system steering values.
