    Abstract: A vehicle has an engine, an accelerator control, a limited slip differential (LSD) mounted on an axle driven by the engine, and left and right wheels operably connected to the LSD. An accelerator control position is sensed. A speed of the vehicle is optionally sensed. In order to prevent wheel spin, a high load is selectively applied to the LSD when the accelerator control position meets or exceeds a predetermined position threshold. Optionally, application of the high load may depend on the speed of the vehicle being less than a predetermined speed threshold, the accelerator control position concurrently meeting or exceeding the predetermined position threshold. In order to enhance directional stability of the vehicle, a stabilization load is optionally applied when the speed of the vehicle meets or exceeds the predetermined speed threshold.

  • Patent number: 10344857
    Abstract: A gear-lever mechanism using meshing and pushing for rotation includes a shell; an input device including a driving gear; an output device including a supporting frame and a driven gear set; and a positioning device including a fixed bearing gear. The driven gear set includes a transfer-layer gear and at least one idler gear. The supporting shaft center of each transmission gear in the driven gear set is the sub-bearing point, with each transmission gear meshed with its adjacent drive gears to form two meshing points. The bearing point and the two meshing points form a triangular pushing area. At least two triangular pushing areas in head-to-tail connection form a meshing-pushing-lever-type torsion-output path curved from the driving gear to the fixed bearing gear for connecting and driving, to cause the gear set to rotate with a raising speed, and then reduce the speed and increase the torque.

  • Patent number: 10221903
    Abstract: One vehicle wheel is disconnected from a differential while the vehicle is in a front wheel drive mode. A controller checks for a malfunction of the differential while the vehicle is in the front wheel drive mode and in response to a request to enter an all wheel drive mode. If speeds of the other vehicle wheel and the differential input indicate that the malfunction is present, the all wheel drive mode is disabled and the driver is informed. If fluid temperature indicates a risk of the malfunction, all wheel drive mode is temporarily disabled and the driver is informed. If the temperature condition continues to be present for a predetermined duration, the all wheel drive mode is disabled.
