TRACTION CONTROL FOR A HYBRID ELECTRIC POWERTRAIN

TRACTION CONTROL FOR A HYBRID ELECTRIC POWERTRAIN

An electric machine and internal combustion engine are coordinated to provide traction control for an automotive vehicle. A propulsive torque limit is set by a controller during a loss of traction. When the machine torque limit is greater than the propulsive torque limit, the engine is pulled down....

Zusammenfassung:An electric machine and internal combustion engine are coordinated to provide traction control for an automotive vehicle. A propulsive torque limit is set by a controller during a loss of traction. When the machine torque limit is greater than the propulsive torque limit, the engine is pulled down. When the machine torque is less than the propulsive torque limit, the engine is pulled up. The controller coordinates the pulled up engine with the machine such that the engine is subordinated to the machine.
