20120095634 | MOTOR TORQUE CONTROL DEVICE - A motor torque control device of an electrically-driven vehicle equipped with a motor serving as a driving source, is configured to limit an output of the motor when both a brake pedal and an accelerator pedal of the electrically-driven vehicle are stepped. A motor limit torque, which is an upper limit value of a command torque for the motor, is changed depending on a vehicle velocity of the electrically-driven vehicle detected by a vehicle velocity detecting unit and a stepping amount of the brake pedal detected by a brake pedal stepping amount detecting unit. | 04-19-2012 |
20120232735 | OUTPUT TORQUE CONTROL SYSTEM - An output torque control system includes a control unit which includes an acceleration mode detection unit and an output torque control unit. The acceleration mode detection unit selects a normal acceleration mode which includes output torque information indicating an increased amount of output torque of an electric motor as time elapses or a rapid acceleration mode which includes output torque information indicating the increased amount of output torque of the electric motor as time elapses more largely than in the normal acceleration mode based on a result of a detection by a depressing speed detection unit. The output torque control unit selects one of the output torque information which corresponds to the result of the detection by the acceleration mode detection unit to control the output torque produced by the electric motor based on the selected output torque information. | 09-13-2012 |
