摘要:
This apparatus is applied to a vehicle brake apparatus provided with a hydraulic booster operated by utilizing an accumulator hydraulic pressure that is adjusted to a predetermined high pressure (not less than a lower limit value) by a drive control of a hydraulic pump. This apparatus executes an automatic pressurization control by controlling plural solenoid valves with the use of the accumulator hydraulic pressure. The increasing slope of the brake hydraulic pressure during the automatic pressurization control is determined on the basis of the vehicle motion state. The increasing slope is restricted to be not more than a predetermined restriction value, in the case where the accumulator hydraulic pressure at the time of starting the automatic pressurization control is less than “a reference hydraulic pressure that is greater than a minimum value of the accumulator hydraulic pressure necessary for assisting the brake operation by the hydraulic booster and smaller than the lower limit value”.
摘要:
A method and apparatus for controlling a vehicle involves determining if the vehicle is swaying and if the vehicle is swaying, reducing a torque of an engine of the vehicle and/or applying independent braking forces to each wheel of the vehicle. A vehicle for controlling vehicle sway includes an engine, a plurality of wheels, a braking system configured to apply independent braking forces to each wheel, and a controller configured to control the engine and the braking system. The controller is configured to determine a correlation coefficient in accordance with any phase shift occurring between a yaw acceleration signal and a lateral acceleration signal. The correlation coefficient is compared to a threshold value to determine whether the vehicle is swaying. If the vehicle is swaying, the controller causes a torque of the engine to be reduced and/or braking forces to be applied independently to each wheel.

A green pigment for a color filter including a phthalocyanine green pigment and capable of expressing a region of xy-chromaticity coordinate enclosed by predetermined equations 1, 2 and 3 defined by the XYZ color system of the CIE when the green pigment is solely subjected to colorimetry. Moreover, using the above-mentioned green pigment, it provides a photosensitive color composition capable of forming a color filter having a wide color reproduction range and a high transmittance. Furthermore, it provides a color filter having a wide color reproduction range and a high transmittance with a green pixel formed using the above mentioned photosensitive color composition, and a liquid crystal panel using the color filter.

A vehicle brake system is provided with a hydraulic brake device, a regenerative brake device incorporating a generator motor, and a brake control device. The control device includes a section for calculating a driver target brake force for each wheel corresponding to a manipulation amount of a braking manipulation member, a section for enabling the brake control device itself to set compensation brake forces for respective wheels, a section for selecting a larger one of the driver target brake force and the compensation brake force for each wheel and for subtracting a base hydraulic brake force from the selected brake force to set differences for respective wheels as compensated target brake forces for the wheels, and a section for controlling the distribution of the compensated target brake force for each wheel to a controlled hydraulic brake force for each wheel and a regenerative brake force for each driving wheel.
