摘要： A vehicle includes an engine and is at least partially propelled by a fraction battery and a traction motor. A clutch is configured to be coupled to the traction motor. An electrical and/or mechanical pump provides pressure to control the clutch. At least one controller determines if the clutch is slipping. In response to the clutch slipping, the at least one controller commands an increase in speed of an input of the clutch such that the available line pressure to control the slipping of the clutch is increased. The line pressure is then applied to the clutch in order to control the slipping of the clutch.

摘要： A method for controlling a downstream clutch in a vehicle during an upstream torque disturbance includes slipping a downstream clutch by reducing the downstream clutch pressure, varying the downstream clutch pressure to a target threshold to control the slip of the downstream clutch, increasing the downstream clutch pressure to engage the downstream clutch. A vehicle includes a first prime mover, a second prime mover connected to the first prime mover using an upstream clutch, a transmission connected to the second prime mover using a downstream clutch, and a controller connected to the first and second prime movers and the upstream and downstream clutches. The controller is configured to (i) slip the downstream clutch by reducing the pressure, (ii) vary the downstream clutch pressure to a target threshold to control the slip, and (iii) increase the downstream clutch pressure to engage the clutch.

摘要： A system and method for controlling a vehicle having an electric traction motor coupled to a transmission by a clutch include modifying traction motor torque in response to the difference between rotational speed of a driveline component and the filtered rotational speed of the driveline component to reduce driveline oscillation when the clutch is locked. The traction motor torque may be modified in response to a vehicle event that may otherwise induce driveline oscillations, such as a transmission ratio change or regenerative braking, for example.

摘要： A vehicle includes a motor/generator, a starter motor, a disconnect clutch disposed between the engine and the motor/generator, and at least one clutch disposed between the motor/generator and the vehicle drive wheels. When an engine start is requested, various parameters are controlled to ensure a smooth engine start wherein driveline torque disturbances are minimized. The starter motor is used to crank the engine upon an engine start request, thereby eliminating the need to transfer torque from the motor/generator to the engine. This helps to further reduce torque disturbances in the driveline when the engine is started.

摘要： A system and method for controlling a hybrid electric vehicle during regenerative braking is provided. The system and method include a brake controller adapted to cause, for a selected transmission gear, a first torque ratio to be applied to a regenerative brake system during regenerative braking and a second torque ratio, different from the first torque ratio, to be applied when the vehicle is not regenerative braking. The first torque ratio results in an increased braking torque generated by the regenerative brake system compared with application of the second torque ratio.

摘要： A control system and method for a hybrid electric vehicle powertrain supplies battery power boost torque to vehicle traction wheels to modify shift points for a multiple ratio transmission in the powertrain. A shift schedule is adjusted to avoid a downshift for small changes in torque demand, thus reducing shift frequency due to small transient changes in torque demand.

摘要： A hybrid vehicle has an engine, an electric machine connected to the engine by an upstream clutch, a transmission gearbox connected to the electric machine by a downstream clutch, and a controller. The controller is configured to start the engine using one of a plurality of start sequences that control the electric machine, the upstream and downstream clutches. The engine start sequence is selected based on transmission gearbox input speed and a driver demand input. A method of controlling a hybrid vehicle is provided. An engine is selectively coupled to an electric machine by an upstream clutch with the electric machine selectively coupled to a transmission gearbox by a downstream clutch. The engine is started using a control sequence to control the electric machine, upstream clutch, and downstream clutch. The control sequence is determined by a vehicle state based on transmission gearbox input speed and a driver demand input.
