TH22817B - Log-up control device - Google Patents

Abstract

DC60 (24/11/41) The lockup control device has been provided to control the gripping force of the lockup clutch, which divides the engine power and the torque converter to transmit power to the power shaft. Now, the target thrust has been realized by taking into account the throttle opening and the speed of the car, the required torque has been made taking into account gear ratios and target thrust. The target engine speed has been achieved by holding the desired torque. Where at target speed The engine mark has been adjusted to avoid abnormal noises and abnormal vibrations, so the lockup clutch is regulated in such a way that the engine speed is not lower than target speed. The meaning of the engine in case of gear shifting corresponds to a shift up, etc. Basically, the clutch lockup is regulated to provide gripping force. Which has been made as much as possible Possible to improve fuel efficiency. In other words Lock up clutch was received. Control to be as tight as possible Or lock up the clutch that has been adjusted initially to the state The tightness was shut down right after the gear shift timing if the actual speed of the machine was predicted. The engine after gear changes will not be lower than the target speed of the engine. The lockup control device is provided to control the gripping force of the lockup clutch, which divides the engine power and the torque converter to transmit power to the powertrain's input shaft. This target thrust was made possible by taking into account the throttle opening and the speed of the vehicle, and the required torque was achieved by keeping the gear ratio and the target thrust. The target engine speed has been achieved by holding the desired torque. Where at target speed The engine target has been adjusted to avoid the occurrence of abnormal noises and abnormal vibrations, so the lockup clutch is regulated in such a way that the engine speed is not lower than target speed. The meaning of the engine in case of gear shifting corresponds to a shift up, etc. Basically, the upclutch lock is regulated to provide gripping force. Which has been made as much as possible It is possible to improve fuel efficiency. In other words Lock up clutch also received. Control to be as tight as possible Or lock up the clutch that has been adjusted originally in the state The tightness was shut down right after the gear shift timing if the actual speed of the machine was predicted. The engine after gear changes will not be lower than the target speed of the engine.
