摘要： A working machine having a working part driven by an engine and a transporting part driven by an electric motor. The rotation of the electric motor is controlled by a control part. The speed of the engine as of when the working part is brought to a working state by a work on/off switch being turned on is taken as a reference speed, and a correction coefficient corresponding to this reference speed is taken as an upper limit value. A correction coefficient corresponding to the present speed of the engine is determined. A required acceleration set in correspondence with the size of the actual travel speed of the transporting part is multiplied by the determined correction coefficient to correct this required acceleration. The control part acceleration controls the rotation of the electric motor in accordance with the corrected required acceleration.

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： 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： 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.
