Vehicle sensing system using daisy chain of sensors

A method for calibrating a plurality of sensors for a sensing system for a vehicle, said method comprising:

• providing a plurality of sensors configured to be disposed at a vehicle and electrically connected to a communication network of the vehicle;
• providing a control in communication with the communication network of the vehicle, wherein the control is operable to process data sensed by the sensors when the sensors are connected to the communication network of the vehicle;
• providing an input to the control that is indicative of the number of sensors that are to be connected to the communication network as part of a daisy chain of sensors;
• connecting the sensors to the communication network of the vehicle;
• responsive to determination that a given connected sensor is connected to the communication network, calibrating the given connected sensor;
• determining via the control whether a given connected sensor is the last sensor of the daisy chain of sensors;
• responsive to determination that a given connected sensor is not the last sensor of the daisy chain of sensors, adjusting the internal electrical configuration to provide an open connection for another sensor;
• and
• responsive to determination that a given connected sensor is the last sensor of the daisy chain of sensors, adjusting the internal electrical configuration to provide a termination configuration.

A sensing system for a vehicle, said sensing system comprising:

• a plurality of sensors disposed at a vehicle and electrically connected to a communication network of the vehicle;
• a control in communication with the communication network of the vehicle, wherein said control is operable to receive data sensed by said sensors via the communication network and to process the data sensed by said sensors;
• wherein said control receives an input that is indicative of the number of sensors that are connected to the communication network as part of a daisy chain of sensors;
• wherein said control is operable to determine address of the individual sensors at the communication network and to individually calibrate the individual sensors based at least in part on the determined address;
• responsive at least in part to the input, said control determines whether an individual sensor is the last sensor of said daisy chain of sensors;
• responsive to determination that an individual sensor is not the last sensor of said daisy chain of sensors, said control adjusts the internal electrical configuration to provide an open connection for another sensor;
• responsive to determination that an individual sensor is the last sensor of said daisy chain of sensors, said control adjusts the internal electrical configuration to provide a termination configuration;
• and
• wherein, with said sensors calibrated, said control processes data sensed by said sensors for at least one of automated parking, blind spot detection, cross traffic alert, lane change and merge aid, automatic emergency braking, pedestrian detection, turn assist, and intersection collision mitigation.
