摘要： When the voltage of a battery is dropped down to a first threshold value (9.5 V) or less, the driving force of a motor is decreased to a level Y(0)-Y(7) of a limit power determined in accordance with a remaining capacity of the battery. When the voltage is not restored even after a predetermined time is lapsed from the decreasing of the driving force to the level Y(0)-Y(7), the driving force is further decreased down to a lower level Y(0)-Y(7). When the voltage of the battery is restored to a second threshold value (10 V), the driving force of the motor is gradually increased up to a level Z(0)-Z(7) of a limit power determined in accordance with the capacity of the battery. Thus, it is possible to prevent a deep discharging of the battery, while minimizing the influence on the traveling of the vehicle.

摘要： A motor control device for controlling the driving and regenerative operation of a motor includes CPU, ROM, RAM and a back-up RAM. An electric power is normally supplied from a subsidiary battery through a second regulator to the back-up RAM. An electric power is also supplied to the CPU, the ROM and the RAM through a main switch and a first regulator, on the one hand, and through the first regulator and a transistor which is turned ON when the number of revolutions of the motor becomes equal to or larger than a predetermined value, on the other hand. Therefore, even if the main switch is opened during traveling of a vehicle at a high speed, the counter-electromotive force of the motor can be decreased by the motor control device which is supplied with the electric power through the transistor to maintain its function, thereby preventing damage to an inverter.

摘要： A neutral apparatus for use on an electric vehicle is disclosed. The neutral apparatus comprises a control state detector and a neutral mechanism control circuit. The control state detector detects whether or not the motor control unit is in a predetermined control state. The neutral mechanism control unit can instruct the neutral mechanism to interrupt the power train according to the output signal from the control state detector. If the motor control unit is not in the predetermined control state, this is detected by the control state detector. In response to the output signal from the control state detector, the neutral mechanism control circuit causes the neutral mechanism to interrupt the power train. Thus, power flow from the motor to the drive wheels is interrupted. The control state detector is comprised of a voltage comparator circuit for comparing the output voltage from the motor driver circuit with a reference voltage and produces an output signal. As a result, it becomes possible to monitor the control state of the vehicle during movement thereof by means of an arrangement simple in construction.

摘要： A control system for an electric vehicle includes an accelerator opening detecting device for detecting a position of an accelerator, and an output command value calculating device connected to the accelerator opening detecting device for calculating an output command value of a drive motor of the electric vehicle based upon the detected accelerator opening. A motor control device is connected to the output command value calculating device, and controls the output of the motor based upon the output command value. An accelerator opening learning device learns actual accelerator opening positions, and includes at least one of a full-closure learning apparatus for generating a full-closure determined value of the accelerator based upon an output of the accelerator opening detecting device, and a full-open learning apparatus for generating a full-open determined value based upon the detected accelerator opening. The system also includes an output command value limiting device for limiting the output command value output by the output command value calculating device until the accelerator opening learning device has generated the full-closure determined value and the full-open determined value. This configuration reduces the rough and unstable output changes of a motor until the learning has been completed.

摘要： An electronic control unit for controlling an inverter mounted between a main battery and a motor in an electric vehicle includes a feed-back control device which ensures that an actual electric power calculated from an electric current and a voltage inputted to the inverter is equalized to a target electric power calculated from the motor revolution-number, an accelerator opening degree and a shift position. If a circuit between the main battery and the motor is opened during regenerative operation, so that the charging of the main battery with a regenerative electric power cannot be performed and as a result, the voltage is increased to exceed a predetermined value, a regeneration prohibiting device prohibits the regenerative operation of the motor to prevent damage to the inverter due to a counter-electromotive voltage of the motor.

摘要： In an electric vehicle in which regenerative braking is performed in preference to hydraulic braking, an uncomfortable vibration generated due to a sudden variation in the load of a motor, is prevented at the start of the regenerative braking. At the start of the braking, the regenerative braking force is gradually increased from a previously set regenerative initial value to a demanded braking force rather than being increased quickly to the demanded braking force, thereby preventing the generation of the vibration. A deficiency in the braking force during this time is compensated for with the hydraulic braking force. When the demanded braking force exceeds a regenerative acceptable value, the regenerative braking force does not exceed the acceptable value, and a deficiency of braking force thereafter is compensated for with the hydraulic braking force.

摘要： In an electric vehicle including a transmission provided between a motor and driven wheels, if a shift change detecting means has detected the shift change from a "D" range or an "R" range to an "N" range or a "P" range when a stoppage detecting means has detected that the vehicle is in its substantially stopped state, a torque command value gradually-decreasing means gradually decreases the torque command value for the motor toward zero. This causes the face pressure of meshed portions of gears within the transmission to be moderately decreased, thereby preventing the generation of a striking sound due to a repulsion of the gear.

摘要： The invention provides a transflective liquid crystal device and an electronic apparatus using the same which do not cause a non-uniformity in the substrate gap, even though a layer-thickness adjusting layer is formed so that the layer thickness balance of a liquid crystal layer between a transmission display region and a reflection display region is optimized thereby. Below a counter electrode of a counter substrate of a transflective liquid crystal device, a color filter for transmission display, being thin and having a wide chromaticity region, is formed in a transmission display region, and a color filter for reflection display, being thick and having a narrow chromaticity region, is formed in a reflection display region. Further, the interval between a TFT array substrate and the counter substrate is adjusted by a columnar protrusion formed on the TFT array substrate, and a gap material is not dispersed between the TFT array substrate and the counter substrate.
