    摘要: In a travel control method for an electric vehicle having first and second electric motors for driving respective first and second driven wheels, a speed of each of the first and second electric motors is calculated. The speed of the first electric motor is reduced to equal the speed of the second electric motor when the speed of the first electric motor is higher than the speed of the second electric motor. Reduction of the speed of the first electric motor is not carried out when a first condition, in which a difference between the speeds of the first and second electric motors is below a first preselected threshold value, and a second condition, in which the speed of the first electric motor is below a second preselected threshold value identical or substantially equal to a low speed range of the electric vehicle, are met.

    摘要: A travel control method of an electric vehicle wherein to raise the straight-line driveability of the electric vehicle speed-reduction control is carried out so that the speed of an electric motor rotating at a higher speed is lowered to match the speed of an electric motor at a lower speed. This speed-reduction control is executed when the speed of the motor at the higher speed is above a preset threshold value. The time taken to reach a predetermined threshold value from immediately after starting is short, and the electric vehicle reaches the desired speed rapidly after moving off.

    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: Simplifying the controller of hybrid type drive unit. The output of a generator driven by engine is connected directly to a motor 7 through a converter or switching circuit 10 without being charged on any battery. The output of each phase of the generator is inputted to the converter 10. A timing controller 126 controls the conduction phase of a thyristor bridge 101 in the converter 10 so as to adjust the quantity of output power. A synchronous standard for phase control is formed based on output wave of an auxiliary winding 26 of the generator. A voltage detector 124 detects an applied voltage on the motor 7 as a motor rotation speed and the conduction angle is increased or decreased so as to maintain a detected voltage at a target value.

    摘要: In an engine drive washing machine, a discharge switch 10 is provided in a jet gun 5. When the switch 10 is turned off, an engine 1 is stopped. When the switch 10 is turned on, the engine 1 is started up to drive a pump 2. When an outlet pressure of the pump 2 is not lower than a predetermined value, a water-discharge valve in the gun 5 is opened to cause the water to be discharged. When the switch 10 is not turned off for a long time, the engine 1 is stopped. When an operator takes up the gun 5 to start the operation, the engine 1 is started up. The engine-drive type of washing machine is provided with a battery 13 for a starter motor, and the battery 13 is charged by a generator function of a starter-motor generator 3 during the operation of the engine 1.

    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.
