  • Patent number: 10793092
    Abstract: In one aspect, a system and method allow for various pairs of candidate gear ratios and engine speeds to be identified for achieving a desired ground speed of a work vehicle. The individual operating efficiencies of one or more of the power-consuming components of the work vehicle may then be analyzed for each pair of transmission/engine settings to estimate the associated parasitic power loss(es) within the system. Based on the parasitic power loss value determined for each transmission/engine setting, a net engine power or torque requirement can be calculated and used as an input for determining the fuel efficiency of the work vehicle at each candidate setting. The gear ratio and corresponding engine speed of the candidate setting associated with the lowest fuel consumption may then be set as the target or desired transmission/engine setting for maintaining the work vehicle at the desired ground speed.

  • Patent number: 10611359
    Abstract: Methods and controllers for coordinating firing fraction transitions that occur in conjunction with transmission shifts are described. In some embodiments, when a transmission shift to a target gear is expected, a target firing fraction is determined that is desired for use after the shift has completed. In selected circumstances, the change to the target firing fraction is initiated prior to the shift to the target gear. The transition to the target firing fraction preferably completes before an inertia/speed phase of the shift. In other embodiments, the engine transitions to all cylinder operation or other suitable transitional firing fraction in response to an expected transmission shift. After the shift completes, a transition is made to a target firing fraction. The described approaches are well suited for use during skip fire or other cylinder output level modulation operation of the engine and are particularly beneficial during up-shifts.

  • Patent number: 10539229
    Abstract: An engagement operation of a dog clutch is carried out while an engagement operation of a second clutch is being carried out, that is, during a situation that an uplock is hard to occur because of a phase shift generated between meshing counterpart members of the dog clutch. Thus, the dog clutch is easily engaged, and it is possible to facilitate preparation for transmission of power through a first power transmission path. If the dog clutch is not engaged, the second clutch is engaged and a second power transmission path is established, so it is possible to start moving a vehicle by transmitting power through the second power transmission path. Thus, when the dog clutch is in a non-engaged state at the time of an N-to-D shift during a stop of the vehicle, it is possible to ensure the startability of the vehicle.

  • Patent number: 10407071
    Abstract: A control device for a vehicle includes: an engine (10); an engine torque adjustment mechanism; and a PCM (50) configured, upon satisfaction of a condition that the vehicle is traveling and a steering angle-related value is increasing, to control the engine torque adjustment mechanism to reduce the engine torque to thereby execute a vehicle attitude control for generating deceleration of the vehicle, and, upon satisfaction of a given terminating condition for terminating the vehicle attitude control, to restore the reduced engine output torque to an original state before the execution of the vehicle attitude control. The PCM (50) sets a time period from the satisfaction of the terminating condition through until start of restoration of the engine torque, such that it becomes longer as the number of times of combustion per unit time becomes larger, and starts to restore the engine torque when the set time period has elapsed.

  • Patent number: 10377371
    Abstract: In some embodiments, a rapid-response active suspension system controls suspension force and position for improving vehicle safety and drivability. The system may interface with various sensors that detect safety critical vehicle states and adjust the suspension of each wheel to improve safety. Pre-crash and collision sensors may notify the active suspension controller of a collision and the stance may be adjusted to improve occupant safety during an impact while maintaining active control of the wheels. Wheel forces may also be controlled to improve the effectiveness of vehicle safety systems such as ABS and ESP in order to improve traction. Also, bi-directional information may be communicated between the active suspension system and other vehicle safety systems such that each system may respond to information provided to the other.

  • Patent number: 10281040
    Abstract: When an engagement-side clutch taking charge of rotation control in a downshift is the same as a rotation control clutch in the previous gear shift or a clutch of which the engagement has been switched in the previous gear shift, there is a likelihood that clutch hydraulic controllability will decrease and the clutch hydraulic controllability is secured by delaying start of the gear shift. It is possible to execute a gear shift which is a downshift without unnecessary waiting by setting a delay time by which the start of the gear shift is delayed depending on an accelerator depression amount such that the delay time is shorter when the accelerator depression amount is small than when the accelerator depression amount is large.
