    摘要: In a test method in which an image photographed by a camera apparatus 1 attached to a body of a vehicle is displayed on a display device 17 and an examiner examines compliance or non-compliance of the shooting direction of the camera apparatus 1 by comparing the position of a reference pattern and the position of a judgment pattern on the displayed photographed image, the photographed image is obtained at first by photographing with the camera apparatus 1 a test chart which is placed at a predefined position ahead of the vehicle with the reference pattern drawn on the test chart. Next, the judgment pattern is set at a specific position on the photographed image. Then, the photographed image on which the judgment pattern has been set is displayed on the display device 17.

    摘要: A stereoscopic optical system images a stereoscopic picture image, a stereoscopic image processing section calculates a three-dimensional distance distribution from the stereoscopic picture image, and an object recognizing section recognizes objects from the distance distribution information to calculate a relative position of the objects with respect to the vehicle. On the other hand, a travelling amount of the vehicle is detected by a steering sensor and a rear wheel rotation sensor. Then, an object positional information calculating section calcuLates a new relative position of the objects based on the relative position information memorized in a memory section and the calculated travelling amount of the vehicle and the memory section memorizes the new positional information. And, a bumping judgment outputting section judges the possibility of bumping against the objects based on the new relative position of the objects with reference to memorized information about the external shape of the vehicle. If it is judged therein that there is a possibility of bumping, the bumping judgment outputting section outputs a warning signal to an indicating section.

    摘要: A system for measuring intake airflow rate in an engine has an airflow meter provided in an intake passage upstream of a throttle valve. The intake airflow rate of the flow entering into a space between the throttle valve and the cylinders of the engine, without entering into the cylinders, is calculated. The difference between the intake airflow rate measured by the airflow meter and the airflow rate of flow in the space is calculated to provide the actual intake airflow rate of flow actually entering into the cylinders.

    摘要: In a method of examining the reliability of distance data calculated based on stereoscopic images, a pair of photographed images is obtained by taking pictures of a test chart 21 carrying a brightness pattern with a stereo camera, the test chart 21 being placed in a shooting direction of the stereo camera. The distance data is calculated from these photographed images by stereo matching. Using the distance data concerning the test chart shown in the photographed images as the evaluation samples, a histogram showing a relationship between distance values of evaluation samples and their frequency of occurrence is produced. The reliability of the calculated distance data is judged by evaluating properties of the histogram thus produced based on the distance between the stereo camera and the test chart.

    摘要: In a control system for controlling the occurrence of an abnormality in one of the computers mounted on a motor vehicle, a decision is made based upon whether a sub CPU has been reset. In the case where the sub CPU is reset by an abnormality or a malfunction, a failsafe mode flag is set and control data are transmitted again from the main CPU to the sub CPU. The interruption is finished after the control command signal is transmitted to the sub CPU. At this time, if the failsafe mode flag is set, the failsafe control is executed. If the failsafe mode flag is not set, the normal control is executed. Therefore, even if the control data in the RAM of the computers are destroyed by the occurrence of an abnormality or malfunction, the system can regain normal operation immediately.
