Patent ID: 8543273

Claim:
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.
