摘要： An electric vehicle includes left and right electric motors for separately driving left and right traveling apparatuses, respectively, and a control unit for controlling the left and right electric motors, separately. When operation of the electric vehicle is switched from a turning mode to a straight-traveling mode if one of the electric motors disposed on the same side as a turning direction of the electric vehicle has a speed not exceeding a predetermined minimum reference speed, the control unit abruptly increases a level of an accelerating control signal for a temporary time from the switching of operation to abruptly accelerate the one electric motor, such that the speed of the one electric motor can be made close to that of the opposite electric motor in a shorter time.

摘要： A self-propelled work machine, in which the load of the work unit increases according to an increase in the travel speed. The self-propelled work machine includes electric motors for driving the travel units, an engine for driving the work unit, a work drive instruction unit for instructing the work unit to turn on, and a control unit for controlling the electric motors. The control unit reduces the actual speed of the electric motors by using PID control so that the actual rotational speed of the engine returns to a reference rotational speed when the actual rotational speed of the engine falls below the reference rotational speed in the state in which the work unit is turned on by the work drive instruction unit. The reference rotational speed is a reference value used when the work unit is driven by the engine.

摘要： The invention makes an output sharing of an engine and an electric motor proper so as to suitably drive a load. When a throttle opening degree variation amount ΔV is within a ΔV1, an engine E can drive a power generator G at a rated revolution speed. A switching circuit 28 is switched in such a manner as to charge a battery 27 by a generated power. When the opening degree variation amount ΔV becomes larger than the ΔV1, a power assist of operating the power generator G as the electric motor is set to be standby. When the opening degree variation amount ΔV is more than ΔV2 (>ΔV1), the power assist is started. In the power assist, an angle advance amount is increased. When acceleration is insufficient, it is possible to further increase a conduction angle in stages.

摘要： In a travel control method for an electric vehicle, an accelerator angle is obtained from a position of an accelerator lever. An accelerator percentage is determined in accordance with the accelerator angle. The ON times of first and second brake buttons are read. Brake percentages of first and second brakes are determined in accordance with the ON times of the respective first and second brake buttons. A control value for a first electric motor is determined by correcting the accelerator percentage with a corrected brake percentage of the first brake obtained by applying an influence of the brake percentage of the second brake to the brake percentage of the first brake. A speed of the first electric motor is controlled using the control value of the first electric motor. A control value for a second electric motor is determined by correcting the accelerator percentage with a corrected brake percentage of the second brake obtained by applying an influence of the brake percentage of the first brake to the brake percentage of the second brake. A speed of the second electric motor is controlled using the control value of the second electric motor.

摘要： An electric vehicle in which left and right electric motors respectively driving left and right transporting parts are controlled by a control part and particular turning control of the electric motors is carried out when the electric vehicle turns. The electric vehicle has a left and right pair of push-button turn switches. When one of the turn switches is operated, the control part selects a pattern from multiple preset deceleration patterns and decelerates the motor on the inside of the turn, which corresponds to the turn switch being operated, on the basis of this deceleration pattern. The electric vehicle makes turns and returns to straight-line travel optimally and smoothly and can be operated easily by an operator with no skill or experience.
