摘要:
When a predetermined time has passed without detection of engine stall and without detection of the neutral state and without detection of a vehicle starting operation, in a first control state in which a clutch is in a disengaged state, a clutch control system effects transition to a second control state in which transition to a third control state is permitted. When a vehicle starting operation is detected in the second control state B in which the clutch is in the disengaged state, a liquid pressure modulator is driven to effect transition to the third control state in which the clutch is put in the engaged state or a partially engaged state. When an engine stall or the neutral state is detected in the second control state, transition to the first control state A is effected.

A start permission decision section issues a start permission when an engine speed and a throttle valve opening become higher than predetermined values. A clutch-torque capacity storage section stores a clutch-torque capacity reference map in which a clutch-torque capacity is set as a function of at least the engine speed or as a function of the engine speed and the throttle valve opening. A clutch-torque capacity correction section corrects the clutch-torque capacity reference map so that the clutch-torque capacity is proportionally reduced in response to the difference between the engine speed and a start permission speed when a start permission is issued. An oil pressure controlling section connects the clutch with the clutch-torque capacity obtained in accordance with the corrected clutch-torque capacity map to start the vehicle.

The thrust load of the friction transfer mechanism is adjusted with an electric actuator, the thrust load of said friction transfer mechanism is be increased with a fixed inclination, at the first stage from the time control is started to the time the predetermined time elapses, the inclination of the thrust load of said friction transfer mechanism is set to the inclination smaller than that of the thrust load of said friction transfer mechanism at said first stage, at the second stage where said friction transfer mechanism moves further to the predetermined position, and the thrust load of said friction transfer mechanism may be increased with the inclination larger than that of the thrust load of said friction transfer mechanism at said second stage, at the third stage where the predetermined time elapses further.
摘要:
A method of controlling a motor vehicle with an automated clutch and an automated transmission includes the steps of: detecting the vehicle speed, detecting if the brake and/or the gas pedal is actuated, detecting whether or not the engine is running, disengaging the clutch if the engine is found to be running while the vehicle is found to be moving faster than a threshold speed, and if at the same time neither the brake nor the gas pedal is found to be actuated, and subsequently re-engaging the clutch if the brake and/or gas pedal is found to be actuated, wherein prior to re-engaging the clutch, a transmission input rpm-rate is determined, and an engine rpm-rate is controlled in such a manner that the respective rpm-rates of the engine and the transmission are brought towards a closer agreement.

A device may include a driver integrated circuit (IC) comprising a first control unit and a second control unit, a first solenoid that is electrically coupled to the first control unit, a second solenoid that is electrically coupled to the second control unit; at least one sensor, a clock that synchronizes a microcontroller and the driver IC, and a peripheral bus that communicatively couples the first control unit, the second control unit. The microcontroller and the driver IC form an outer control loop that actuates the first solenoid and the second solenoid, and the first control unit, the second control unit, and the at least one sensor form an inner control loop that controls the first solenoid and the second solenoid.
摘要:
A motor vehicle, in particular a passenger car, is provided with an internal combustion engine, a drive wheel arrangement that can be connected to the former, a clutch for the optional connecting and disconnecting of internal combustion engine and drive wheel arrangement, an actuator for actuating set clutch, and a controller for controlling set actuator, The set controller comprises a comparator for comparing a set quantity and an actual quantity and an actuator that is equipped in order to in particular partly close or open the clutch based on this comparison of set quantity and actual quantity, and to a method for the automatic actuating of the clutch.
摘要:
A clutch control apparatus for a vehicle provided with a hydraulic clutch in the middle of a power transmission path between an engine and a drive wheel. Before the clutch of the vehicle is brought into an engagement state, intermittent hydraulic pressure Y is applied to the clutch while maintaining the clutch in a disengagement state, and thereafter a predetermined hydraulic pressure is applied to the clutch to bring it into the engagement state. A solenoid valve is provided to control hydraulic pressure supplied to the clutch. Before the clutch is brought into the engagement state, a pulsed drive current D is supplied to the solenoid valve. The clutch control apparatus so configured suppresses a motion delay at the time of engaging the clutch, thereby allowing a quick and smooth start and shifting of the clutch.

A method is provided for estimating a transmissibility of a clutch in a vehicle powertrain, which includes, but is not limited to cutting off fuel supply of an engine driving a first side of the clutch, setting a clutch pressure between first and second sides of the clutch to a positive value at which there is a non-zero difference between angular accelerations at the first and second sides of the clutch, and deriving the estimated transmissibility from a deviation between the angular acceleration difference and an angular acceleration caused by a drag torque of the engine.
