    Abstract: A lidar sensing system for a vehicle includes a plurality of lidar sensor modules disposed at a vehicle, with each lidar sensor module having a laser unit and a sensor unit, and with each lidar sensor module having a respective field of sensing exterior of the vehicle. Each field of sensing is different from the other fields of sensing and partially overlaps at least one other field of sensing. An output of each lidar sensor module is communicated to a control, and the control, responsive to outputs from the lidar sensor modules, determines a combined field of sensing.

    Abstract: A vehicle control system for a vehicle includes a plurality of sensors disposed at a vehicle and having respective fields of sensing exterior of the vehicle. A processor is operable to process data captured by the sensors, and a control, responsive to processing by the processor of data captured by the sensors, controls a plurality of vehicle systems and is capable of autonomous control of the vehicle to autonomously drive the vehicle along a road. The vehicle control system includes a user input that is selectively actuatable by an occupant of the vehicle so that the occupant can select one of at least (i) a non-autonomous mode where the occupant has driving control of the vehicle and non-autonomously drives the vehicle along the road, and (ii) an autonomous mode where said control autonomously drives the vehicle along the road.

    Abstract: A sensing system for a vehicle includes a plurality of sensors disposed at the vehicle. The plurality of sensors includes individual sensors connected to a vehicle network using a daisy chain topology. A control determines an address of the sensors and calibrates the sensors. The control, responsive to determination that an individual sensor is not the last sensor of a daisy chain of sensors, adjusts the internal electrical configuration to provide an open connection for another sensor. The control, responsive to determination that an individual sensor is the last sensor of the daisy chain of sensors, adjusts the internal electrical configuration to provide a termination configuration. The control, responsive to the outputs of the sensors, determines the presence of one or more objects exterior the vehicle and within the field of sensing of at least one of the sensors.

    Abstract: A vehicular driving assist system includes a plurality of lidar sensors having respective fields of sensing exterior the vehicle. The lidar sensors emit light pulsed at a respective pulse rate and provide a respective output to an electronic control unit based on sensed light that is reflected by objects present in the field of sensing of the respective lidar sensor. The pulse rates of light emitted by the lidar sensors are different. The vehicular driving assist system, via processing at the ECU of the outputs from the lidar sensors, generates a three dimensional (3D) point cloud. The vehicular driving assist system controls the vehicle based at least in part on light sensed by the lidar sensors that is reflected by the objects when light is emitted by the lidar sensors at the respective pulse rates.

    Abstract: A method for calibrating a vehicular vision system includes disposing a camera at a vehicle, disposing a processor at the vehicle, and disposing a video display screen in the vehicle so as to be viewable by the vehicle driver. The video display screen is operable to display video images derived from image data captured by the imager of the camera. Image data is captured by the imager of the camera and provided to the processor. The video display screen displays video images derived from image data captured by the imager of the camera. The processor generates a graphic overlay for display with the video images at the video display screen. Responsive to processing captured image data, the vehicular vision system is calibrated by adapting an orientation and position of the image data relative to the generated graphic overlay to a corrected orientation and position relative to the generated graphic overlay.

    Abstract: A vehicular driving assist system includes a plurality of lidar sensors having respective fields of sensing exterior the vehicle, with the fields of sensing of first and second lidar sensors partially overlapping at an overlap region. The lidar sensors emit a respective pattern of light and provide a respective output to an ECU based on sensed light that is reflected by objects present in the field of sensing of the respective lidar sensor. The pattern of light emitted by the second lidar sensor differs from the pattern of light emitted by the first lidar sensor. The ECU determines misalignment of the second lidar sensor relative to the first lidar sensor based at least in part on the light sensed by each of the lidar sensors that is reflected by an object present in the overlap region when the respective pattern of light is emitted by the respective lidar sensor.
