  • Patent number: 10066738
    Abstract: A method of controlling a transmission having a gearbox and a pump operable to circulate a fluid through the gearbox, includes sensing an acceleration of the vehicle, and adjusting an operating state of the pump. The operating state of the pump is adjusted to change the operating state of the pump from an initial operating state, to an adjusted operating state, when the acceleration of the vehicle is greater than an acceleration threshold. When the acceleration of the vehicle decreases from being greater than the acceleration threshold to being below the acceleration threshold, the operating state of the pump is returned to the initial operating state. The operating state of the pump may include a speed of the pump, a control signal representing a fluid flow rate for the current speed of the pump, or a fluid flow circuit for supplying the fluid to the pump.

  • Patent number: 10065646
    Abstract: An engine stop control device is provided for a vehicle that ensures a sufficient operation frequency of coast stop operation during travel on a congested road, thereby to improve practical fuel economy. The vehicle has an engine that is capable of being restarted. A controller is configured to stop the engine automatically when the vehicle, after experiencing a travel with a vehicle speed VSP exceeding a first threshold value, decreases the speed below a CS (coast stop) start vehicle speed. The controller is further configured to set a second threshold value below the first threshold value. The controller is further configured, after starting from an engine automatic stop due to the coast stop control and when the vehicle experiences travel exceeding the second threshold value without exceeding the first threshold value, to permit the automatic engine stop due to the coast stop control at least once.

  • Patent number: 10047800
    Abstract: A vehicle has a transfer case that is configured to receive power from a transmission, and transfer the power to one or both of a front axle and a rear axle. The transfer case has an output, such as an output rod, that delivers the power to a differential on one of the axles. A driveshaft has a single constant-velocity joint thereon. A first shaft of the driveshaft is directly connected to the output of the transfer case by a fixed connection, such as a spline connection, that inhibits axial slipping. The first shaft is connected on its other end to the constant-velocity joint. A second shaft of the driveshaft is connects to the constant-velocity joint to the differential. The driveshaft can also have a clamp at the splint to inhibit axial slipping at the spline connection.
