摘要:
A display unit is disposed in front of a driver's seat in a front central region of a passenger compartment of a vehicle. A sensor senses a condition, such as a driver's eye position, an outside brightness and a steering frequency, affecting the uneasiness of a driver caused by the display screen. A controller reduces the size of a picture display region in accordance with the condition to achieve an agreeable size and position of picture on the screen.

In display apparatus and method for an automotive vehicle, a display (2) is disposed on a position of the vehicle placed in a proximity to a dashboard surface of the vehicle and a controller (7), when a state of the vehicle which satisfies a predetermined condition is detected, executes a process to gradually reduce a brightness of an image screen of the display toward a predetermined direction which is more distant from a direction of a line of sight of a vehicular driver when the vehicular driver gazes a vehicular forward direction. In one embodiment, the controller gradually reduces the brightness of the image screen of the display toward the predetermined direction in a linear manner. The predetermined direction is, for example, directed from an upper end of the image screen to a lower end thereof.

A fuel cell power plant system for a moving body includes a drive device (2) for driving the moving body by receiving power,-a power plant (10) having a fuel cell (1) for supplying power to the drive device (2) and a fuel supply device (3) which supplies fuel required by the fuel cell (1) to generate power, and a controller (6). When the moving body has stopped, the controller (6) selects one operating mode from plural operating modes according to the running state of the power plant (10), the fuel cell (1) not generating power to be supplied to the drive device in the plural operating modes, and controls the power plant (10) based on the selected operating mode.

A vibration sensor is disposed at an evaluation point on the vehicle floor proximate the driver's seat. This sensor, in combination with one disposed on a electrically controllable engine mount, is used to determine the magnitude and orientation of a vector of vibration which reaches the evaluation point and which combines with other vibrational vectors in a manner which results in the generation of vibration at the evaluation point. A mount control signal is controlled in a manner which modifies the vibration vector and attenuates the vibration at the evaluation point.

In order to attenuate vibration which tends to be transmitted from a power unit to a vehicle passenger during the idling mode of engine operation, ERF filled engine mounts are arranged so that when neither of two orifice passages are restricted by impressing a voltage on ERF viscosity control electrodes included therein, the frequency at which the dynamic spring constant exhibits a minimum value is the same as the frequency at which the vibration transmission phase maximizes while one of the two orifice passages is restricted by the application of a voltage on the set of electrodes disposed therein. Rapid cyclic control of the dynamic spring constant and the vibration transmission phase for each mount used to support a power unit is carried out. This enables a desirable compromise in the control of the two different parameters.

An active noise eliminating system comprises microphones for detecting residual noise, speakers for generating noise elimination sound for interference with the residual noise, a noise generating condition sensor for generating noise condition, a controller for generating noise elimination signals inputted to the speakers and determined by the detected residual noise signals and the detected noise condition signal in accordance with a control algorithm including transfer functions between the speakers and microphones respectively. The transfer functions are updated on the basis of a test signal generated when noise sound diverges.

摘要:
An apparatus for reducing periodical noises transmitted from a noise source into a vehicle passenger compartment. The apparatus comprises control sound sources for producing control sounds in the vehicle passenger compartment, residual noise sensors for detecting the residual noises in the vehicle passenger compartment, transfer function filters modeled on transfer function between the control sound sources and the residual noise sensors, and adaptive digital filters having variable filter coefficients. A reference signal is produced in the form of a series of impulses having the same period as the noises. The transfer function filters are convoluted with the reference signal to produce reference processed signals. The adaptive digital filters are convoluted with the reference signal to generate drive signals to drive the control sound sources. The filter coefficients of the respective adaptive digital filters are updated based on the processed reference signals and the residual noises to reduce the noises in the vehicle passenger compartment.
