摘要:
A powertrain system including a multi-mode transmission is configured to transfer torque among an input member, torque machines and an output member. A method for controlling the multi-mode transmission includes employing a closed-loop speed control system to determine torque commands for physical torque actuators including the torque machines. The closed-loop speed control system includes employing a virtual torque actuator control scheme to generate torque commands for the physical torque actuators responsive to output commands for a plurality of virtual torque actuators.

A method for controlling a multi-mode transmission system employing torque machines under dynamic operating conditions includes calculating a phase shift between a control parameter of one of the torque machines and a response parameter of the multi-mode transmission system under dynamic operating conditions, comparing the calculated phase shift and an expected phase shift, and executing remedial action when the calculated phase shift exceeds a threshold associated with the expected phase shift.

A method for controlling a hybrid electric vehicle having a control system, a traction motor, and an engine includes generating an activation signal during a predetermined vehicle maneuver. The predetermined vehicle maneuver is a threshold hard braking maneuver on a surface having a low coefficient of friction. The method also includes processing the activation signal using the control system, and using the traction motor to command an injection or a passing of a feed-forward torque to the driveline of the vehicle. The feed-forward torque is in the same direction as the engine torque, and prevents a drive shaft of the engine from spinning in reverse during the maneuver. The method may include generating the activation signal in response to detecting an active state of the ABS controller. A hybrid electric vehicle includes an engine, a traction motor, and a control system configured to execute the above method.

A vehicle includes a traction motor, a transmission, a speed encoder for the motor, and a control system. The control system compensates for angular wobble in an encoder signal. The control system receives, via a hybrid control processor (HCP), the encoder signal from the speed encoder, and determines a set of wobble characteristics of the encoder signal below a threshold motor speed. The control system also calculates a wobble-compensated speed value via the HCP using the wobble characteristics, and uses the wobble-compensated speed value as at least part of the input signals when controlling the motor. A lookup table tabulates a learned wobble value relative to the angular position value, and a learned wobble value is subtracted from a current angular wobble value to generate an error-adjusted wobble value. A method compensates for wobble in the encoder signal using the above control system.
摘要:
A method for controlling driveline stability in a vehicle includes generating an activation signal indicative of a predetermined vehicle maneuver, which may include a hard braking maneuver on a low coefficient of friction surface. A quick automatic shift to a neutral gear state is executed with a rapid dumping or bleeding off of clutch pressure in a designated output clutch of the vehicle. An activated state of an antilock braking system (ABS) may be used as part of the activation signal. The shift to the neutral gear state may occur only when a current transmission operating state is associated with the high level of driveline inertia. A vehicle includes a transmission and a control system configured to execute the above method.
摘要:
A method or algorithm controls a motor in a vehicle having a proportional-integral controller. The controller determines a commanded damping control torque as a proportional output torque value and a commanded motor speed control torque as an integrator output torque value. The integrator torque output value is frozen only if the proportional torque output value saturates against a limit and the direction of the speed error is the same as that of the integrator torque output value. The proportional torque output value is calculated using different error values than are used in calculating the integrator output value. A vehicle includes one or more traction motors and the controller noted above. For two motors, the controller determines the damping torques and motor speed control torques separately for each motor.
摘要:
A method for minimizing driveline disturbances in a vehicle includes using a controller to automatically combine a damping torque control command with a motor speed control command in a closed loop to prevent a perceptible discontinuity in an applied motor torque during a change in transmission gear states. The method may include calculating error values in the rotational speeds of one or two traction motors, and using the calculated error value(s) to determine a required damping torque. The controller can multiply the error value for one traction motor by a gain value of the other traction motor before determining the required damping torque. A vehicle includes first and second traction motors, a transmission, and a controller. The transmission is powered by the traction motors, and the controller combines a damping torque control command with motor speed control command to prevent a discontinuity in an applied motor torque as noted above.
