Kind of yes, kind of no.
Hydraulic brakes, with constant pressure will do more work, more slowing action ( evidenced by creating more heat ) at higher speeds, and gradually taper the work done as the vehicle slows, evidenced by creating less heat at the slower speeds.
Electrodynamic brakes in EVs and hybrids provide constant braking power. It does not taper down with slower speeds, as was the case with hydraulic brakes. This provides linear stopping power, but people are used to tapered stopping power. The constant stopping power feels like an increase, because people are used to a decrease with hydraulic.
This is not my speculation.
This is how it works.
The Maverick gives you 32 kW of slowing at 85 MPH.
The Maverick gives you 32 kW of slowing at 55 MPH.
The Maverick gives you 32 kW of slowing at 5 MPH.
The power is linear. The braking effort is linear. People want and expect a taper. This is where creative programming plays a role.
Because 32 kW of braking at 85 mph FEELS mild. 32 kW of braking at 5 mph FEELS strong.
When the Maverick hits 3 MPH electrodynamic "regen" suddenly turns off. At (hopefully) the same moment hydraulic brakes turn on. But getting the feel of the hydraulic to match the regen is a real challenge. And this is what the "programming update" is all about.
And Shay, you can quote me on this if you want in a future video.
