摘要:
A vehicular brake control apparatus detects risky occasions and locations that may be risky by using, for example, an infrastructure information input device or a navigation device, and, for such locations and the like, performs the pre-charge so that braking force will be promptly generated. Therefore, the pre-charge can be precisely performed under necessary circumstances, irrespectively of the driver's accelerator operation. Hence, when the driver depresses the brake pedal at such a location or the like, braking force will be promptly generated. Thus, accidents and the like can be prevented.

In a display apparatus, a luminance acquiring unit acquires luminance signals from inputted image signals. A difference calculating unit compares luminance signals of the current frame acquired by the luminance acquiring unit with those of a previous frame stored in a frame memory, and then takes a difference between these luminance signals. If the difference of the luminance is large, a judging unit judges that the image corresponding to a portion in question is moving. If the difference of the luminance is small, the judging unit judges that the image corresponding to the portion stays still. A gain calculating unit gradually lowers the luminance corresponding to a part where the image stays still, and gradually restores to the original level the luminance corresponding to a part where the image is moving.

In a self-luminous type display in which one pixel includes four unit pixels of RGBW, a signal processing circuit includes first, second and third parts. The first part subtracts a minimum value in RGB input signals from each input signal of RGB. The second part calculates an RGBW signal corresponding to the case in which all the RGB input signals are the minimum value, based on an RGB signal value for realizing target white when all the RGB input signals are a maximum value. The third part determines the RGBW signal by adding a signal corresponding to each RGB subtraction result to the RGBW signal calculated by the second part. Each RGB subtraction result is calculated by the first part.

An automatic steering control performs an automatic parking control which automatically steers steerable wheels of a vehicle, without requiring a driver to perform steering wheel operation, such that the actual steering angle of the steerable wheels follows a changing target steering angle, whereby the vehicle is moved to a target parking state. When the actual steering angle fails to follow the target steering angle because of insufficiency of the steering drive force of a steering actuator, a braking force difference imparting control is performed so as to apply a predetermined braking force on the steerable wheel located inside a target vehicle locus. As a result, a steering moment is generated in the steerable wheels. This steering moment serves as a force for compensating for the insufficiency of the steering drive force of the steering actuator. As a result, the actual steering angle accurately follows the target steering angle.

A target vehicle path is corrected in accordance with the environment surrounding a vehicle during parking assist or U-turn assist. To achieve the target vehicle path, target wheel speeds are set for respective wheels so as to generate a speed difference an inside wheel and an outside wheel of a turn. The target wheel speed is achieved by controlling braking force and driving force of each wheel. Thus, it is possible for the vehicle to turn with a smaller turning radius than that generated by a normal steering angle, and to cause the vehicle to move accurately along the target vehicle path that avoids any obstacles that are present.

A technology for reducing the so-called “phosphor burn-in” phenomenon where the variation of luminance arises by reducing display luminance of a certain pixel caused by deterioration in a display apparatus constituted by an organic electro luminescence element is provided. In the display apparatus, when displaying an image acquired by an image acquiring unit, luminance substantially same as average luminance of the acquired image is set to a non-display area where the image is not displayed.

In image signal processing, the color saturation values of image signals are accumulated within each of a plurality of color saturation calculation regions by a color saturation accumulator circuit 13, and the image signals obtained in a color saturation calculation region in which the result of the color saturation value accumulation thus performed by the color saturation accumulator circuit 13 is low are accumulated for each of image signal types C1 to C4 by an image signal accumulator circuit 14. Based on the results of this accumulation performed for each of the image signal types C1 to C4, constants with which to counterbalance the amounts of light transmitted for the image signals C1 to C4 are determined and fed to a transmitted light amount corrector circuit 1. Moreover, based on the results of the color saturation value accumulation performed for each color saturation calculation region by the color saturation accumulator circuit 13, weight factors are determined and fed to a luminance signal generator circuit 6. The luminance signal generator circuit 6 receives, through a VLPF 4, the image signals for which the amounts of light transmitted have been counterbalanced by the transmitted light amount corrector circuit 1, and also receives image signals produced by smoothing the image signals obtained from one set of a plurality of adjacent pixels after another through the VLPF4 and an HLPF 5. The luminance signal generator circuit 6 produces luminance signals by adding together these signals with the weight factors assigned thereto.

An infrared ray receiving module receives an infrared signal (transmitted by an image display device) generated on the basis of a signal representing switching between right and left eye images. An input signal type automatic judging unit and a field frequency detecting and L/R distinguishing unit acquire data relating to shutter timing of a left eye liquid crystal and a right eye liquid crystal in liquid crystal shutter glasses from the received infrared signal. An operation field frequency determining unit generates decision data relating to shutter timing to be fed to the liquid crystal shutter glasses on the basis of predetermined conditions from the data relating to shutter timing newly obtained in succession, and holds the generated decision data. A liquid crystal driving pulse generating unit can cause the liquid crystal shutter glasses to perform a shutter operation using the held decision data when no decision data is generated because the predetermined conditions are not satisfied. Consequently, it is possible to maintain the shutter operation even if the infrared signal is blocked.

Estimation of tire air pressure based on a resonance frequency extracted based on a wheel speed signal outputted from a wheel speed sensor corresponding to the respective tire and estimation of tire air pressure based on a dynamic load radius derived based on the wheel speed signal, are used to selectively switch in accordance with a magnitude of a variance value of the resonance frequency at a plurality of time points.
