摘要： In a system for controlling active suspensions of a motor vehicle, having fluid suspensions for the respective wheels, a longitudinal acceleration sensor, control valves for the respective suspensions, and a controller for adjusting the control valves to charge and discharge a fluid into and out of the fluid suspensions so as to control the vehicle attitude, a hysteresis circuit is provided to receive a longitudinal acceleration signal from the acceleration sensor, for hysteresis processing of the signal, whereby microvibration components included in the acceleration signal is removed. The width of hysteresis is increased as the vehicle speed increases because the amplitude of microvibration becomes larger as the vehicle speed increases. For more stable vehicle attitude control, a dead-zone circuit is provided to cut fluctuations of the hysteresis-processed signal within a specific width in the vicinity of zero.

摘要： Vehicle height control for a motor vehicle which has height adjusting means for each of wheel suspensions and which is stationary on a distorted road surface. Height control is carried out for either one of the front wheel suspension pair and the rear wheel suspension pair to attain a reference vehicle height for both the left and right wheels of the one pair whereby the vehicle part having said one pair assumes an attitude parallel to the inclination of the road surface in a direction transverse to the vehicle part. For the other pair of the wheel suspensions, height control is carried out such that the opposite part of the vehicle with the other pair of the wheel suspension will assume an attitude substantially equivalent to the attitude of the first mentioned vehicle part, whereby a good balance is obtained between the contact loads of the wheels.

摘要： A vehicle front-view monitoring system determines whether there is a fail occurring on the monitoring system based on luminance data on an image of a front view taken by camera and takes fail-safe measures if the fail is occurring. The luminance data indicates luminance-distribution characteristic values indicating horizontal luminance-distribution on the image. A fail can be determined based on a parameter obtained by normalizing the luminance-distribution characteristic values by a shutter speed for the camera equipment.

摘要： When a vehicle is moving out of a lane of a road, an image processing computer unit judges the hazardous condition. Then, a power steering control computer unit calculates a correction reaction force based on the steering angular velocity and increases a steering reaction force so as to generate a large steering effort. This lane moving-out prevention system is constituted such that only when the steering angular velocity is large, i.e., when a driver turns a steering wheel sharply, the steering reaction force is increased, thereby no additional reaction force is produced when the driver makes a normal turn.

摘要： A braking force control system comprises a yaw rate sensor for detecting an actual yaw rate of a vehicle, a target yaw rate calculating section for detecting a vehicle speed and a steering angle to calculate a target yaw rate, a yaw-rate difference calculating section for calculating a difference in yaw rate by subtracting the target yaw rate from the actual yaw rate, and a braked-wheel discriminating section for selecting a rear-inside wheel as a braked wheel when the sign of the actual yaw rate is different from that of the difference in yaw rate, and for selecting a front-outside wheel as the braked wheel when the sign of the actual yaw rate is the same as that of the difference in yaw rate. Therefore, when the vehicle is in an under-steering tendency, the rear-inside wheel is selected, and when it is in an over-steering tendency, the front-outside wheel is selected. In addition, the system may further comprise an output discriminating section for comparing the difference in yaw rate with a discriminating threshold to discriminate as to whether the difference in yaw rate is within a control region. A first threshold is set as the discriminating threshold. After the under-steering tendency is changed to the over-steering tendency, a set period of time and a second threshold, the absolute value of which is smaller than that of the first threshold, are set. With this construction, it is possible to smoothly perform the control without giving uncomfortable feeling to a driver, and it is also possible to restrain the control by a rear wheel.
