摘要:
A hybrid vehicle comprises a drive wheel (5), an internal combustion engine (1), a power generating motor (2) that generates an electric power by using an output power of the engine (1), and a planetary gear set (13) that comprises a combination of a gear element that is driven by the engine (1), a gear element that is connected to the power generating motor (2), and a gear element that is connected to the drive wheel (5). A target engine power is computed based on an accelerator operation amount. The engine (1) is controlled based on the target engine power. And control a rate of variation in the rotation speed of the engine (1) to be smaller, when the rotation speed of the power generating motor (2) increases than when the rotation speed of the power generating motor (2) decreases toward zero as a result of controlling the engine (1) based on the target engine power. Fuel consumption rate is thus improved.

In preceding vehicle following control apparatus and method for an automotive vehicle, a vehicular velocity controller includes a target inter-vehicle distance calculating section that calculates a target inter-vehicle distance from the vehicle to a preceding vehicle detected by an inter-vehicle distance sensor on the basis of a vehicular velocity detected by a vehicular velocity detector and an inter-vehicle distance detected by an inter-vehicle distance detector, a first vehicular velocity controlling section that performs a vehicular velocity control to bring the detected inter-vehicle distance substantially coincident with the target inter-vehicle distance, and a vehicular deceleration stopping section that performs a vehicular deceleration control to stop the vehicle in accordance with the inter-vehicle distance from the vehicle to the preceding vehicle immediately before a time point at which the inter-vehicle distance detector which trapped the presence of the preceding vehicle has not detected the preceding vehicle when the detected vehicular velocity falls in a low vehicular velocity region lower than a predetermined velocity value and -the inter-vehicle distance detector which trapped the presence of the preceding vehicle has not detected the preceding vehicle.

An adaptive vehicle speed control system includes a vehicle speed sensor detecting a vehicle speed of a host vehicle which is subjected to adaptive vehicle speed control including preceding vehicle following control and vehicle speed control, and an inter-vehicle distance sensor detecting an inter-vehicle distance between the host vehicle and a preceding vehicle. A man-machine interface is provided for setting a set vehicle speed. Also provided is an adaptive vehicle speed controller which includes a desired inter-vehicle distance arithmetic-processing section calculating a desired inter-vehicle distance based on at least the host vehicle speed, a following control section determining a desired speed of the host vehicle based on the host vehicle speed and the inter-vehicle distance so that the inter-vehicle distance is brought closer to the desired inter-vehicle distance in presence of detection of the preceding vehicle, and a vehicle-speed adjustment device which adjusts the host vehicle speed to the desired speed. The adaptive vehicle speed controller includes a vehicle speed setting section which sets the desired speed to a speed value higher than a low-speed threshold value when the adaptive vehicle speed control function is engaged under a specified condition where the host vehicle speed is below the low-speed threshold value.

A write laser power setting device for setting a write laser power for writing data on a recording medium, includes first and second oscillators and for producing carrier signals having high frequencies f1 and f2. The carrier signals are added with each other to produce a sum signal which is applied to a laser driver for producing a laser drive signal. The power of the laser drive signal is changed to various levels. Using the laser drive signal, the write/read head writes test signals at preselected areas on the recording medium such that different writing power levels are applied to different preselected areas, respectively. After writing the test signals, the write/read head reads the recorded test signals. From the read signal, an unwanted signal having a frequency f1-f2 is filtered, and the level of the unwanted signal is detected and stored. A minimum level of the stored levels is selected, and a preselected area at which the minimum level reading is obtained is detected. Then, the writing laser power is set at a writing power level corresponding to the level used for writing the test signal in the detected preselected area.
摘要:
a temperature control device for a liquid crystal optical shutter allows information writing on a photosensitive body such that a plurality of microshutters are opened/closed to selectively transmit light from a light source onto the surface of the photosensitive body. The ambient temperature near the liquid crystal optical shutter is detected by a thermistor. The temperature control device includes a first temperature controller for causing a thermistor to detect the ambient temperature near the liquid crystal optical shutter and for variably controlling an energization ratio of the heater for heating the liquid crystal optical shutter, and a second temperature controller for controlling energization of the heater at an energization ratio different from that of the first temperature controller.
