  • Patent number: 11105070
    Abstract: To increase frequency of use of auto idle, an engine is accelerated even more quickly than before and work involving a heavy load can be performed within a short period of time when an operator resumes work and recovers a speed of the engine. When an operation lever device is operated and the speed is low because of auto idle control, a pilot pump is unloaded to thereby reduce load torque on the engine. Operation of a compressor is also suspended while an air conditioner is operating. Furthermore, for a target speed of the engine, a speed at which work can be performed is set and the engine is accelerated. When the engine thereafter reaches a predetermined speed or a predetermined period of time thereafter elapses, the pilot pump is loaded and the operation of the compressor for the air conditioner is resumed.

When the continuously-variable transmission mechanism is in a failure state in which an actual gear ratio of the continuously-variable transmission mechanism is not the highest gear ratio as a target gear ratio, the control apparatus sets the target gear ratio to a transient target gear ratio that is gradually changed toward the highest gear ratio, for causing the actual gear ratio to be gradually changed toward the highest gear ratio.

  • Patent number: 10794435
    Abstract: A transmission includes a selectable one-way clutch with an active state and a passive state. To avoid occupant discomfort and hardware damage, transitions from the passive state to the active state must only be commanded when no or very little slip is present across the selectable one-way clutch. Several methods are presented to eliminate slip, depending on vehicle speed. When the vehicle is stationary, full engagement of a clutch that causes slip to be proportional to vehicle speed eliminates slip. When the vehicle is moving backwards, partial engagement of the above clutch eliminates slip. When the vehicle is moving forwards, full engagement of all but one clutch of a tie-up condition and partial engagement of the remaining clutch of the tie-up condition brings the vehicle to a stop and eliminates slip.

    Abstract: A method is for the safe starting of a combustion engine in a handheld, portable work apparatus. When starting, start rpm limiting is activated when the rotational speed of the combustion engine exceeds an activation rotational speed that lies above the coupling rotational speed of a centrifugal coupling. After activating the start rpm limiting for at least one working cycle, an intervention in the ignition is carried out such that the rotational speed of the combustion engine decreases. After the rotational speed has decreased below a lower engagement rotational speed, an intervention in the ignition is carried out such that the rotational speed increases. If the rotational speed exceeds an upper engagement rotational speed, an intervention in the ignition is again carried out such that the rotational speed decreases. The upper engagement rotational speed and/or the lower engagement rotational speed is/are changed with an increasing number of consecutive working cycles.

The drive circuit controls a driving current of the actuator supplied from a DC power source through a power line based on the control pulse in which the transition timing is controlled. The communication block generates the communication clock, and modulates a current flowing through the power line in response to data to be transmitted during a signal transmission period different from the operation period, set within the communication cycle.

  • Patent number: 10414400
    Abstract: A control device for a vehicle includes: an engine (10); an engine torque adjustment mechanism; and a PCM (50) configured to execute vehicle attitude control for, upon satisfaction of a vehicle attitude control executing condition that the vehicle is traveling and a steering angle-related value is increasing, reducing the engine torque to thereby generate deceleration of the vehicle. The PCM (50) is configured, upon satisfaction of a given terminating condition for terminating the vehicle attitude control, to control the engine torque adjustment mechanism to restore the reduced engine torque to an original state before the execution of the vehicle attitude control. The PCM (50) sets a rate of change in the engine output torque being restored, such that it becomes larger as the number of times of combustion per unit time becomes smaller, and restores the engine torque according to the rate of change set in the above manner.

  • Patent number: 10408342
    Abstract: In a transmission hydraulic control system, a gain control valve may be used to switch between a low gain and a high gain based on line pressure. Line pressure may be controlled as a function of turbine torque. If the gain of a holding element or oncoming element changes during a shift as a result of changing turbine torque, shift quality may degrade. If the gain is set low at the beginning of the shift, the controller limits engine torque to ensure that the line pressure is not increased beyond a level that would cause a gain switch. If the gain is set high at the beginning of a shift, the controller maintains the line pressure high enough to prevent a switch to low gain, even if turbine torque drops.

    Abstract: A power transmission includes a first brake, a pressure regulating valve, an accumulator, an oil temperature sensor, a second electromagnetic valve allowing supply of working oil to a piston, and a power transmission control device. The power transmission control device includes a memory relating and storing a working oil temperature and a permission time configured to allow release of the accumulator, and a receiver unit receiving a starting request. The accumulator is connected such that the working oil, in which the pressure is accumulated, can be supplied to the first brake and the piston. The power transmission control device sets a permission time corresponding to a temperature of the working oil on the basis of the memory. The working oil, in which the pressure is accumulated, is supplied to the first brake only during the permission time when restart information is received, while a vehicle performs idling stop control.

  • Patent number: 10336332
    Abstract: An electronic control unit permits a shift operation to a neutral position, by which a manual transmission 14 is switched to neutral, during coasting control. Accordingly, shifting to the neutral position can be performed only by the shift operation. Thus, power transmission can be blocked after termination of the coasting control. In addition, the electronic control unit prohibits the shift operation to a particular gear after the transmission is switched to neutral. Thus, overreving or underreving at the termination of the coasting control can be suppressed.
