Abstract: A vehicular camera includes a lens assembly and a circuit board having a first side and a second side opposite the first side. The circuit board has a first coefficient of thermal expansion (CTE). An imager is disposed at the first side of the circuit board and optically aligned with the lens assembly. A bend-countering element is disposed at the second side of the circuit board. The bend-countering element has a second CTE that is greater than the first CTE of the circuit board. The bend-countering element counters temperature-induced bending of the circuit board. With the camera disposed at the vehicle, temperature-induced bending of the bend-countering element is in an opposite direction from temperature-induced bending of the circuit board.

Abstract: A vehicular vision system includes a plurality of cameras disposed at a vehicle and having respective exterior fields of view. Each camera includes an image sensor and a microcontroller having memory, and each camera is in communication with a vehicle controller. Image data captured by the image sensor of each camera is communicated to the vehicle controller. The vehicle controller communicates control data to each camera, and the communicated control data is stored in memory of each camera. With the communicated control data stored in the memory of each camera, the vehicle controller communicates a trigger signal to each camera during operation of the vehicle and vision system. Responsive to the communicated trigger signal, the microcontroller of each camera loads parameters of the control data stored in the respective memory into the respective image sensor so that the parameters of the image sensors of all of the cameras are synchronized.

Abstract: A vehicular object detection system includes a camera and a lidar. With the camera mounted at a windshield of a vehicle, and with the lidar mounted at an exterior portion of the vehicle, and based at least in part on processing of image data captured by the camera and lidar data captured by the lidar, a plurality of individual objects present exterior of the vehicle are detected. Based at least in part on processing of captured image data and captured lidar data, (i) respective proximity relative to the vehicle of individual objects is determined, (ii) respective speed relative to the vehicle of individual objects is determined and (iii) respective location relative to the vehicle of individual objects is determined. Based at least in part on processing of captured image data and/or processing of captured lidar data, the system determines collision potential between the vehicle and an individual object.

Abstract: A vehicular imaging system includes a camera disposed behind a windshield of a vehicle and viewing through a portion of the windshield. Image data captured by the camera is provided to a control. The control receives, via a communication bus of the vehicle, at least one selected from the group consisting of (i) vehicle pitch information relating to pitch of the vehicle, (ii) vehicle yaw information relating to yaw of the vehicle and (iii) vehicle steering information relating to steering of the vehicle. The system automatically corrects for misalignment of the camera. Image data captured by the camera is processed at the control for a lane departure warning system of the vehicle and for at least one selected from the group consisting of (i) an automatic headlamp control system of the vehicle, (ii) a collision avoidance system of the vehicle and (iii) an adaptive front lighting system of the vehicle.

Abstract: A vehicular camera includes a camera housing having front and rear camera housing portions. An imager is disposed at a printed circuit board. A lens assembly is disposed at the front camera housing portion and accommodates at least one lens. The front camera housing portion is formed of a material having a first Coefficient of Thermal Expansion (CTE). At least two attachment elements are disposed at the front camera housing portion and are formed of a material having a second CTE that is less than the first CTE of the front camera housing portion and that is less than 10 ppm/° C. The printed circuit board is mounted at the attachment elements via fasteners threadedly engaging respective ones of the at least two attachment elements. The front camera housing portion and the attachment elements cooperate to decrease temperature-induced movement of the printed circuit board relative to the at least one lens.

Abstract: A method of calibrating a multi-camera vision system includes moving a vehicle along a vehicle assembly line having targets at respective side regions, with each target including a longitudinal line and a plurality of tick marks that extend laterally from the longitudinal line. As the vehicle moves along the vehicle assembly line it is equipped with a plurality of cameras and an image processor. As the vehicle moves along the vehicle assembly line, the target at a respective side region of the vehicle assembly line is present within the fields of view of front, side and rear cameras. Image data is captured by the cameras and processed to detect the targets and to determine misalignment of at least one of the cameras. The vehicular multi-camera vision system is calibrated by adjusting processing by the image processor of image data captured by the at least one misaligned camera.

Abstract: A vehicular camera includes a camera housing having a rear camera housing and a front camera housing. The front camera housing includes a lens, an imager and an imager printed circuit board. The lens is held in position relative to the imager by a UV-curable adhesive. With the lens held in position relative to the imager by the adhesive, the outer surface of the imager is devoid of the adhesive and an air gap exists between the lens and the outer surface of the imager. With the adhesive disposed in an uncured state on the imager printed circuit board and laterally outboard of the imager, and with the lens positioned relative to the imager, the adhesive is cured from its uncured state to an at least partially-cured state by exposure to UV light. The rear housing portion is joined at the front housing portion.

Abstract: A vehicular control system includes a camera disposed at an in-cabin side of a windshield of a vehicle, the camera viewing forward of the vehicle through the windshield, and the camera capturing image data representative of at least an upcoming road surface of a road ahead of the vehicle. The vehicular control system, via processing at an image processor of image data captured by the camera, determines traction condition of at least a portion of the imaged upcoming road surface that is ahead of the vehicle. The vehicular control system, via processing at the image processor of captured image data, determines a change in traction condition ahead of the vehicle and adjusts an adaptive cruise control system of the vehicle responsive at least in part to the determined change in traction condition ahead of the vehicle.

Abstract: A vehicular vision system includes a plurality of cameras and an ECU. The cameras are in communication with one another via a vehicle network and image data captured by the cameras is provided to the ECU. Responsive to a type of driving maneuver of the vehicle, (i) the ECU generates a first control signal that enables automatic control of exposure, gain and white balance of one camera of the plurality of cameras and (ii) the ECU generates respective second control signals that disable automatic control of exposure, gain and white balance of at least one other camera of the plurality of cameras. Responsive to processing of captured image data, composite video images derived from image data captured by the plurality of cameras are synthesized, and composite images are displayed that provides bird's eye view video images derived from video image data captured by the cameras.
