摘要： A method of automatically equalizing image data generated by a surround-view camera system of a vehicle. The method includes receiving a first, second, third, and fourth data set including image data corresponding to a front, left, right, and rear field of view of the vehicle, respectively. The method also includes identifying a darkest region in the first, second, and third data sets and adjusting a brightness of the image data included in the first, second, and third data sets based on the darkest region. The method further includes adjusting a brightness of the image data included in the fourth data set based on a comparison of the brightness of the image data included in the fourth data set and the adjusted brightness of the image data included in the second and third data sets.

摘要： An ultrasonic sensor system (40) has a transducer (44) that emits an ultrasonic signal (52), in response to an electrical excitation signal (50) from driver/receiver circuitry (46), and outputs an electrical response signal (56), in response to receipt of a reflected ultrasonic signal (54) from an occupant (54). The transducer (44) rings-down upon termination of the excitation signal (50). The transducer (44) has a natural resonant frequency that is subject to change. In an occupant sense mode, a receiver portion (68) of the driver/receiver circuitry (46) and a controller (30) process the response signal (56), resulting from transducer excitation at a predetermined frequency, to determining distance between the transducer (44) and the occupant (14). In an adjust mode, the controller (30) varies the frequency of the excitation signal (50) over a range of frequencies, and monitors the ringdown of the transducer (44) during the variation of the frequency to determine a current natural resonant frequency of the transducer (44). The controller (30) changes the predetermined frequency to the determined natural resonant frequency, so that subsequent operation in the sense mode utilizes the resonant frequency.

摘要： A sensor arrangement (40 and 50) and an associated method are provided for sensing at least one occupant characteristic of a vehicle occupant (14). At least one transmitter (e.g., 42A) transmits an energy signal (e.g., 44A) toward an occupant location within a vehicle (12). At least one detector (e.g., 60A) detects whether absorption of the energy signal (42A) by the occupant (14) occurs and provides a signal (e.g., 74A) indicative thereof. An occupant sense module (50) processes the signal (74A) to determine at least one occupant characteristic. Preferably, the sensor arrangement (40 and 50) is part of an occupant protection system (10).
