1. A sensing system for a vehicle, said sensing system comprising:
- a plurality of sensors disposed at a vehicle;
wherein said plurality of sensors comprises individual sensors connected as a chain of sensors to a vehicle network;
a control, wherein outputs of said sensors are communicated to said control, and wherein said control, responsive to said outputs of said sensors, determines presence of one or more objects exterior the vehicle and within a field of sensing of at least one of said sensors; and
wherein, responsive to determination that a given sensor is the last sensor in the chain of sensors, said sensing system provides a termination configuration at that sensor.

Abstract
A sensing system for a vehicle includes a control and a plurality of sensors disposed at the vehicle. The plurality of sensors includes individual sensors connected as a chain of sensors to a vehicle network. Outputs of the sensors are communicated to the control, which, responsive to the outputs of the sensors, determines presence of one or more objects exterior the vehicle and within a field of sensing of at least one of the sensors. Responsive to determination that a given sensor is the last sensor in the chain of sensors, the sensing system provides a termination configuration at that sensor.

10. 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; connecting the sensors as a chain of 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 chain of sensors; responsive to determination that a given connected sensor is the last sensor of the chain of sensors, adjusting an internal electrical configuration to provide a termination configuration; and processing via the control data sensed by the sensors for at least one selected from the group consisting of (i) automated parking, (ii) blind spot detection, (iii) cross traffic alert, (iv) lane change and merge aid, (v) automatic emergency braking, (vi) pedestrian detection, (vii) turn assist, and (viii) intersection collision mitigation. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
