Patent ID: 8214096

Claim:
A method for controlling an accelerator for an electric vehicle having a motor, an accelerator pedal depth sensor, and a vehicle speed sensor, the method comprising the steps of: a) determining an actual accelerator pedal depth value (Gain) based on output from the accelerator pedal depth sensor, and determining a current vehicle speed (V) based on output from the vehicle speed sensor; b) determining a maximum output torque (T m ) of the motor based on a current vehicle speed (V); c) controlling the output torque (T) of the motor according to a formula T=T m *ƒ(Gain); wherein application of the formula T=T m *ƒ(Gain) governs the output torque (T) such that: during a first period of time, a growth rate of the output torque (T) is greater than a growth rate of the actual accelerator pedal depth value (Gain); and wherein during a second period of time, a growth rate of the output torque (T) approximates the growth rate of the actual accelerator pedal depth value (Gain).
