ABSTRACT:
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.
