Braking
When I lightly press the brakes on a 2008 Ford Escape Hybrid, am I engaging (a) the generator only or (b) the generator and the disk brakes? I've seen many hybrid drivers hit the brakes early when they stop (ie when they are at the top of a long off-ramp or when they are still far from a red light). It appears they are doing this so they may capture as much electricity as possible when they stop.
Can someone confirm for me that I am not engaging the disk brakes when I lightly press the brakes on my hybrid? How do I know when the disk brakes are engaging in addition to the generator? Thank you |

Thank you Some of the early Prius adopters built systems for measuring brake line pressure to tell when the mechanical brakes are engaged. Later, they realized that without enough mechanical braking to 'wipe the rotors clean,' you could get corrosion that would eat the rotors. I'm not sure how the Ford Escape handles this but I suspect it is similar to the Toyota system. GOOD LUCK! Bob Wilson |
Re: Braking
It works like ( probably ) all hybrids. About 50% of your brake power can come from the generator. So imagine how much it would take to skid the tires, cut that in half, and the lower half will be regen.
A Ford hybrid designer told me to put a large book on the passenger seat. If the book does not slide off, you are not using brake pads. Watch your charge / assist needle. If the needle moves to charge, 99% of the time you are not using brake pads. There are times when the battery is full, or too hot ( 100'F + ) or too cold ( 25'F or less ) and the brake pads will go on from the start. ( those temperatures are not exact cut-offs, just examples of when the use of brake pads becomes more likely ) -John |

Speaking of Prius, following charts are the comparison between THS(2001-2003) and THS-II(HSD:2004-)...
http://www.toyota.co.jp/en/tech/envi...s2/system.html The THS applies regen plus slight hydraulic and THS-II applies all regen. I don't know which technology is used on FEH. Ken@Japan http://www.toyota.co.jp/en/tech/envi.../system_05.gifhttp://www.toyota.co.jp/en/tech/envi.../system_06.gif |
