Assignee:

Ford Motor Company - Dearborn MI

International Classification:

B60K 1304

US Classification:

180165, 180 654, 180 652, 180 653

Abstract:

A regenerative brake control method and system for a hybrid electric vehicle (HEV) with a disconnect clutch separating the engine from the motor. When the engine is disconnected from the HEV powertrain, more regenerative braking energy is possible because the negative powertrain torque of the engines friction and pumping is eliminated. The control can determine when to disconnect and reconnect the engine to the powertrain using, for example, driver demand, vehicle speed, accelerator position, brake pedal position, engine state, motor state, and motor fault status. The control also minimizes powertrain disturbance to improve vehicle drivability by continuously adjusting the amount of regenerative braking to correspond to the changing torque of the engine on the powertrain during disconnect or reconnect.

Ford Global Technologies, LLC - Dearborn MI

International Classification:

B60K 4102

US Classification:

477 5, 477 3, 180 652

Abstract:

The invention provides a strategy to stop a parallel HEV powertrain engine while maintaining smooth vehicle response to driver demand using the motor while simultaneously opening an engine disconnect clutch. In the preferred embodiment, the strategy stops an engine (based on, for example, driver demand), disconnects the disconnect clutch to the powertrain, halts fuel to the engine, and predicts a desired motor/generator speed. The prediction of desired motor/generator speed can be: a trajectory comparison based on present and past vehicle velocity and deceleration or on a vehicle accelerator position, or a determination of whether the vehicle is in speed following control mode. The system can also add additional strategies such as accelerate the strategy if a vehicle brake is applied. The gradual takeover by the motor occurs by proportionally decreasing actual engine torque until engine torque is zero while maintaining vehicle velocity using for example a proportional plus integral controller.

US Classification:

180 652, 180 653, 180 654, 701 22

Abstract:

The invention provides a strategy to start a parallel HEV powertrain engine while maintaining a smooth vehicle response to driver demand using the motor while simultaneously closing an engine disconnect clutch. In the preferred embodiment, the strategy starts an engine (based on, for example, driver demand), closes the disconnect clutch, commands a desired motor/generator speed, fuels the engine, calculates a desired engine torque and gradually reduces actual motor/generator torque while proportionally increasing actual engine torque until motor/generator torque is zero while maintaining vehicle velocity using, for example, a proportional plus integral controller. The prediction of a desired motor/generator speed can be: a trajectory comparison based on present and past vehicle velocity and acceleration or on vehicle accelerator position, or a determination of whether the vehicle is in speed control mode. The system can also add additional strategies such as a termination strategy if a vehicle brake is applied.

Assignee:

Ford Global Technologies, Inc. - Dearborn MI

International Classification:

H02J 700

US Classification:

320104, 320103

Abstract:

A starter/alternator system ( ) for hybrid electric vehicle ( ) having an internal combustion engine ( ) and an energy storage device (34) has a controller ( ) coupled to the starter/alternator ( ). The controller ( ) has a state of charge manager ( ) that monitors the state of charge of the energy storage device. The controller has eight battery state-of-charge threshold values that determine the hybrid operating mode of the hybrid electric vehicle. The value of the battery state-of-charge relative to the threshold values is a factor in the determination of the hybrid mode, for example; regenerative braking, charging, battery bleed, boost. The starter/alternator may be operated as a generator or a motor, depending upon the mode.

International Classification:

B60L 1102

US Classification:

701 22, 180165, 180 652, 477 2

Abstract:

A vehicle system controller for a vehicle having an engine, a motor/generator, and subsystem controllers is provided. The vehicle system controller includes a state machine having a number of predefined states which represent vehicle operating modes. The predefined states include a motor drive state, which represents a vehicle operating mode wherein the motor/generator provides all driveline torques. The vehicle system controller further includes a set of rules which define logical relationships between each of the predefined states. A set of commands, unique to each state, are supplied to the subsystem controllers. The commands are provided to the subsystem controllers to achieve desired vehicle functionality within the states, and to transition between different states.

International Classification:

B25B023/14
G01L003/02

US Classification:

7386223, 73862193

Abstract:

A method for monitoring torque in an electric motor is provided. First, the motor current is measured and the AC torque is determined based on the measured current. The speed of the motor and the DC motor power are then determined. The DC torque is calculated as a function of the DC motor power and the motor speed. The DC torque is then compared to the AC torque. After the AC torque is verified, it is compared to a reference torque to determine if the difference between the torques is within a torque deviation tolerance.
