Claim 0:
1. A system for scheduling regenerative braking torque, comprising:
a pedal sensor configured to output a position signal indicating a position of an accelerator pedal;
a torque request device coupled to the pedal sensor and operable to generate a torque request value in response to the position signal;
a speed sensor configured to output a speed signal indicating a speed of operation of a motor/generator; and
a controller coupled to the speed sensor and the torque request device, the controller being configured to determine a torque limit in response to the torque request value and the speed signal, generate a regenerative braking command in response to the torque limit, and output the regenerative braking command to the motor/generator,
wherein the system is configured to:
modify the torque limit in response to a state of a brake pedal, and
modulate the regenerative braking torque in response to modifying the torque limit, and

wherein the system is further configured to increase the torque limit in response to the state being a released state.
