Method and system with selectable multimode control of regenerative braking torque limitation

An apparatus for controlling regenerative braking of a vehicle, the apparatus comprising:

• a user interface configured to facilitate a user to provide an input to select an operating mode for the vehicle;
• and
• a controller coupled with the user interface, the controller configured to:
• receive from the user interface the input associated with the operating mode, the operating mode selected from one of selectable modes comprising:
• (i) manually controlled regenerative braking mode and (ii) automatically rolled regenerative braking mode;
• responsive to selecting the (i) manually controlled regenerative braking mode, apply a scaling factor to a regenerative torque capability curve of the vehicle based on an additional user input;
• and
• responsive to selecting the (ii) automatically controlled regenerative braking mode, automatically apply the scaling factor to the regenerative torque capability curve of the vehicle based on one or more traction control events and environmental factors.

A vehicle system comprising:

• an energy storage device;
• a drive unit comprising a prime mover configured to apply regenerative braking to convert mechanical energy into electrical energy during braking to be stored in the energy storage device;
• and
• an apparatus for controlling the regenerative braking of the vehicle system, the apparatus comprising:
• a user interface configured to facilitate a user to provide an input to select an operating mode for the vehicle system;
• and
• a controller coupled with the user interface, the controller configured to:
• receive from the user interface the input associated with the operating node, the operating mode selected from one of selectable modes comprising:
• (i) manually controlled regenerative braking mode and (ii) automatically controlled regenerative braking mode;
• responsive to selecting the (i) manually controlled regenerative braking mode, apply a scaling factor to a regenerative torque capability curve of the vehicle system based on an additional user input;
• and
• responsive to selecting the (ii) automatically controlled generative braking mode, automatically apply the scaling factor to the regenerative torque capability curve of the vehicle system based on one or more traction control events and environmental factors.

An apparatus for controlling regenerative braking of a vehicle, the apparatus comprising:

• a user interface configured to facilitate a user to provide an input to select an operating mode for the vehicle, the operating mode selected from one of the following selectable modes comprising:
• (a) maximum regenerative braking mode, (b) minimum regenerative braking mode, (c) manually controlled regenerative braking mode, and (d) automatically controlled regenerative braking mode;
• and
• a controller coupled with the user interface, the controller configured to:
• receive from the user interface the input associated with the operating mode that is selected;
• responsive to selecting the (a) maximum regenerative braking mode, enable maximum regenerative torque capability for the vehicle;
• responsive to selecting the (b) minimum regenerative braking mode, enable minimum regenerative torque capability for the vehicle;
• responsive to selecting the (c) manually controlled regenerative braking mode, manually adjust a regenerative torque capability curve of the vehicle based on an additional user input;
• and
• responsive to selecting the (d) automatically controlled regenerative braking mode, automatically adjust the regenerative torque capability curve of the vehicle based on one or more traction control events or environmental factors.
