Control of a hybrid vehicle with a manual transmission

摘要

A vehicle includes a transmission that receives torque from an engine and/or a motor. A clutch assembly that may be actuated by a driver is operably disposed between the transmission and the motor, the engine, or both. A controller is configured to control the torque provided by the motor and the engine to prevent engine stall, excessive engine flare, or both, during manual actuation of the clutch assembly by the driver of the vehicle.

主权项

1. A vehicle comprising:
a transmission having an input shaft; an engine having a crankshaft, wherein the engine is configured to provide an engine torque via the crankshaft to the input shaft of the transmission; a motor configured to provide a motor torque to the input shaft of the transmission; a clutch pedal having a clutch pedal position; a clutch assembly operably disposed between the transmission and at least one of the motor and the engine, wherein the clutch assembly is configured to be manually actuated by a driver of the vehicle via the clutch pedal; a clutch pedal position sensor configured to determine the clutch pedal position; and a controller in communication with the clutch pedal position sensor that is configured to detect an engagement of the clutch assembly using the determined clutch pedal position, control the torques provided by the motor and the engine to synchronize a rotational speed of the crankshaft with a rotational speed of the input shaft and thereby reduce slip across the clutch assembly during the engagement of the clutch assembly, and prevent at least one of engine stall and engine flare during the manual actuation of the clutch assembly.
