Cruise control with braking activated brake regeneration

A controller unit that facilitates mitigating hard braking applications and extending a brake regeneration period in a commercial hybrid host vehicle upon detection of a fast approaching forward vehicle, comprising:

• a memory that stores computer-executable instructions for extending a brake regeneration period in a commercial hybrid vehicle upon detection of the fast approaching forward vehicle;
• a processor configured to execute the computer-executable instructions, the instructions comprising:
• receiving an indication of the detected fast-approaching forward vehicle;
• determining that the fast approaching vehicle has breached at a predetermined fast approach threshold;
• initiating brake regeneration-adjusted compressor control;
• determining whether brake regeneration capacity is available;
• and
• sending a brake regeneration command to a traction motor to initiate brake regeneration to slow the host vehicle prior to initiation of friction braking if brake regeneration capacity is available;
• when brake regeneration is not available, comparing a measured air tank pressure in an onboard electric air charging system to a cut-out air pressure threshold;
• determining that the cut-out air pressure threshold has been exceeded;
• determining that the cut-out pressure threshold is at a nominal operating threshold value;
• increasing the cut-out air pressure threshold by a predetermined amount;
• and reevaluating whether brake regeneration is available.
