Abstract
Abstract A false-creep generator device for an electric vehicle equipped with an automatic transmission controls an electric motor (3) to cause the electric vehicle to creep when the accelerator pedal of the electric vehicle is not depressed, no brake is applied to the electric vehicle, the transmission is in a drive or reverse position, and the speed of travel of the electric vehicle is lower than a predetermined creep speed. <IMAGE>

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
188 words
A device for generating false creep for an electric vehicle equipped with a transmission, comprising: an electric motor for propelling the electric vehicle; drive control means for converting a DC voltage from a battery to control said electric motor; shift position detecting means for detecting whether the transmission is in a shift position to move the electric vehicle; a controller for applying a control signal to said drive control means when the transmission is in a shift position to move the electric vehicle; accelerator operation detecting means for detecting whether an accelerator pedal of the electric vehicle is depressed or not; vehicle speed detecting means for detecting a speed of travel of the electric vehicle; brake operation detecting means for detecting whether a brake is applied to the electric vehicle or not; and torque command means for outputting a low torque command value to said drive control means when the. accelerator pedal is not depressed, the brake is not applied, the transmission is in a shift position to move the electric vehicle, and the speed of travel of the electric vehicle is lower than a predetermined creep speed.
Claim 2
Dependent Claim
18 words
A device according to claim 1, wherein said shift position is a drive position or a reverse position.
Claim 3
Dependent Claim
23 words
A device according to claim 1 or 2, wherein said controller comprises means for outputting no control signal when the brake is applied.
Claim 4
Independent Claim
144 words
A device for generating false creep for an electric vehicle equipped with a transmission, comprising: an electric motor for propelling the electric vehicle; shift position detecting means for detecting whether the transmission is in a shift position to move the electric vehicle; accelerator operation detecting means for detecting whether an accelerator pedal of the electric vehicle is depressed or not; vehicle speed detecting means for detecting a speed of travel of the electric vehicle; brake operation detecting means for detecting whether a brake is applied to the electric vehicle or not; and control means for outputting a relatively low current to said electric motor when the accelerator pedal is not depressed, the brake is not applied, the transmission is in a shift position to move the electric vehicle, and the speed of travel of the electric vehicle is lower than a predetermined creep speed.
Claim 5
Dependent Claim
18 words
A device according to claim 4, wherein said shift position is a drive position or a reverse position.
Claim 6
Dependent Claim
27 words
A device according to claim 4 or 5, wherein said control means comprises means for outputting no current to said electric motor when the brake is applied.
Claim 7
Independent Claim
65 words
A device for controlling an electric motor (3) of an electrically-propelled vehicle, characterised in that said device controls said motor (3) to propel said vehicle at a creep speed when the vehicle transmission is in a shift position to move the vehicle, the vehicle accelerator pedal is not being depressed, the vehicle speed is below a reference speed, and the vehicle is not being braked.
