A liquid crystal display device includes a panel having pixel electrodes arranged at intersections of a plurality of signal lines via switching elements for transmitting display data and a plurality of scanning lines for transmitting control signals, and a control circuit for controlling the panel. The liquid crystal panel is divided into first pixel regions and second pixel regions adjacent to the first pixel regions. The control circuit carries out impulse driving in which the control signals transmitted to each of the scanning lines are activated two times in one frame period for displaying an image. The control circuit writes the display data in either one of the pixel regions and writes reset data in the other pixel regions when the control signals are activated once of the two times. By writing the reset data in the pixel regions, the display data written in an immediately preceding frame are reset. In consecutive frames, the display data written in the pixel regions are always reset in one frame period. Therefore, blurring in a moving image can be alleviated. Since writing the display data and the reset data is carried out separately in the first pixel regions and in the second pixel regions, flicker is prevented from occurring in a display screen.

According to the present invention, a control apparatus for an electric generator includes a power generation cost determiner determining a power generation cost of the generator, a threshold determiner determining a threshold of power generation cost as a function of a state of charge of an electric energy storage device, a comparator comparing the power generation cost of the generator with the threshold, and a controller. When the power generation cost of the generator is lower than the threshold, the controller controls the generator to generate an increased amount of electric power, so as to both charge the electric energy storage device and feed an electrical load. Otherwise, when the power generation cost of the generator is higher than the threshold, the controller controls the generator to generate a decreased amount of electric power, so as to allow the electric energy storage device to discharge to feed the electrical load.

In a vehicle-mounted power supply system, the automotive generator generates a voltage for charging a first battery. Power conversion circuitry is connected between the first battery and a second battery that is connected to an electrical load to operate in a first mode or in a second mode when power consumption of the load is lower or higher than a specified value, respectively. In the first mode, the power conversion circuitry maintains the voltage at the second battery at a substantially constant level and in the second mode, the voltage at the second battery varies with the voltage at the first battery. In response to a vehicle speed variation, the automotive generator is controlled so that its output voltage is varied at a first rate when power conversion is performed in the first mode and varied at a second rate lower than the first rate when power conversion is performed in the second mode.

A base engine torque generated with an estimated intake air amount is estimated. An engine torque is corrected by correcting an ignition timing based on a difference between a required engine torque and the base engine torque. A torque correction amount is calculated based on a correction amount of the ignition timing. An actual engine torque is estimated based on the calculated torque correction amount and the base engine torque. A permitted component driving torque is a difference between the actual engine torque and the required vehicle driving torque. A component is controlled based on the permitted component driving torque.
