摘要： A self-propelled snowplow vehicle includes a vehicle frame equipped with an auger at a front end portion thereof and pivotally connected to a propelling frame equipped with driving wheels, and a frame lift mechanism for lifting the front end portion of the vehicle frame up and down relative to the propelling frame. The frame lift mechanism comprises an electro-hydraulic cylinder actuator having a piston rod and an electric motor rotatably driven to produce a fluid pressure for reciprocating the piston rod in response to operation of a manual operating switch. The snowplow vehicle also includes a control unit arranged to forcibly stop the electric motor when a predetermined time has elapsed after the operation switch is activated, the predetermined time being equal to an operating time of the cylinder actuator which is required to extend or contract the piston rod over a maximum stroke defined between a fully extended position and a fully contracted position of the piston rod.

摘要： In the working machine wherein the output of an engine generator is directly supplied to a motor for travel without using the intermediary of a battery, preventing the engine from slowing down. The generator G is directly connected to the motor 7 and there is no battery that stores the output of the generator G. CPU 102 decreases the power supply for the motor 7 when it has been anticipated that the engine revolutions will be decreased. The number of the engine revolutions is detected according to the period of the waveform of an output of the generator G. The alternating current waveform that has been drawn out from one phase of the winding of the generator G is shaped into a rectangular waveform. CPU 102 detects the period of the shaped waveform. When the detected period has become larger, the CPU 102 determines that the engine revolutions is about to decrease.

摘要： A dual-motor electric vehicle having a control section that determines whether three conditions are satisfied, (1) that a straight-ahead travel instruction has been supplied to the vehicle, (2) that an actual number of motor rotations of an electric motor is less than a target number of motor rotations, and (3) that a motor control signal for bringing the actual number of motor rotations closer to the target number has reached a predetermined upper limit output value. When all conditions are satisfied for at least one of the electric motors of the dual-motor vehicle, the control section performs a downward motor-rotation correction process for at least one of motors by incrementally reducing one of the target number of motor rotations and the upper limit output value of the motor control signal until the respective actual numbers of rotations of the left and right motors substantially coincide with each other.

摘要： Control section determines necessary acceleration of a transporting section in accordance with an actual transporting speed, and also determines a correction coefficient corresponding to the number of rotations of an engine from among correction coefficients having a characteristic of becoming closer to a value of one as the number of rotations of the engine increases. The control section multiplies the necessary acceleration by the correction coefficient to thereby provide corrected necessary acceleration, and controls rotation of a transporting drive motor in accordance with the corrected necessary acceleration. When the amount of electric power to be generated by a power generator driven by the engine has increased, the control section controls the opening of a throttle valve.

摘要： In a small electric motor vehicle equipped with an electric motor for driving wheels through a reduction gear mechanism, a first predetermined voltage is immediately applied to the electric motor when a drive-off instruction is generated from vehicle standstill and then the voltage is increased at a predetermined rate until the voltage exceeds a second predetermined voltage, and is then controlled such that the driving speed converges to a desired speed. With this, since the application of the first predetermined voltage slightly rotates the electric motor to take up reduction gear mechanism backlash, shock at drive-off caused by reduction gear mechanism backlash can be reduced or eliminated even when a high-capacity electric motor is used to enhance hill-climbing performance, and smooth drive-off is possible. Furthermore, since the rate of increase/decrease of the driving speed is varied in proportion to the difference between a set speed and a calculated command speed, the driving feel is therefore improved.
