1. A driver assist system for a vehicle, said driver assist system comprising:

  • an object detection sensor disposed at the subject vehicle and having an exterior field of view;

    a receiver disposed at the subject vehicle and operable to receive a wireless communication, said wireless communication associated with at least one of (i) a driving condition of another vehicle and (ii) a road condition of interest to a driver of the subject vehicle;

    wherein said wireless communication comprises at least one of (a) a car-to-car communication and (b) a communication from a communication system associated with a roadway or infrastructure;

    a control disposed at the subject vehicle and operable to process data captured by said object detection sensor to detect an object exterior of the subject vehicle;

    wherein said driver assist system is operable to adjust said processing of said data responsive at least in part to said wireless communication received by said receiver;

    wherein said control is operable to adjust said processing of said data to a distant mode responsive to said wireless communication being indicative of the subject vehicle traveling along a highway, and wherein, when processing said data in said distant mode, said driver assist system is operable to detect an object approaching the subject vehicle from a first distance from the subject vehicle near the effective range of said object detection sensor;

    wherein said control is operable to adjust said processing of said data to a nearby mode responsive to said wireless communication being indicative of the subject vehicle traveling along a city road, and wherein, when processing said data in said nearby mode, said object detection sensor is operable to detect an object of interest at a second distance from the subject vehicle;

    wherein said first distance is greater than said second distance and wherein, when processing said data in said nearby mode, said control does not process data to detect objects at the first distance from the subject vehicle;

    wherein, responsive to said processing of said data, at least one of (a) an alert is operable to alert the driver of the subject vehicle of a potential hazard and (b) a system of the subject vehicle is operable to control a vehicle function to mitigate or avoid a potential hazard condition; and

    wherein said driver assist system is operable to alert the driver of the subject vehicle to not open a vehicle door when the subject vehicle is parked and when said system detects another vehicle approaching the subject vehicle in a side lane adjacent to the subject vehicle.
