Abstract:
1. A method for operating regenerative braking in an automotive vehicle having a plurality of axles, comprising the steps of: determining a brake demand for a first axle; determining the availability of regenerative braking of said first axle to satisfy said brake demand; determining a brake demand for a second axle; determining the availability of regenerative braking of said second axle to satisfy the braking demand for said second axle; and in the event that regenerative braking available for the first axle is greater than the brake demand for the first axle, and in the further event that the regenerative braking available for the second axle is less than the braking demand for the second axle, applying any surplus regenerative braking to the first axle in an amount not greater than the amount needed to satisfy any unmet braking demand for the second axle.
