  • Patent number: 9856977
    Abstract: [Object] To provide a shift control device that, in a shift control device of a vehicle equipped with an idling-stop mechanism and a shift-by-wire mechanism, is capable of preventing setting off at a timing that the driver does not expect when returning from an idling-stop state. [Solution] The SBW-CU (40) that constitutes the shift control device (1), in the case of selection information for selecting the R range being output during an idling stop, switches the shift range of the automatic transmission (10) to the R range when the vehicle is braked, and switches the shift range to the N range or the P range when the vehicle is not braked and the shift range of the automatic transmission (10) is the D range. Also, the SBW-CU (40), in the case of selection information for selecting the R range being output during an idling stop, maintains the shift range without switching it when the vehicle is braked and the shift range of the automatic transmission (10) is other than the D range.

  • Patent number: 8958967
    Abstract: A braking-force control device has a brake control function for performing brake control on a front outside wheel when a vehicle is detected to be in an oversteer condition during a turning operation and for performing brake control on a rear inside wheel when the vehicle is detected to be in an understeer condition during a turning operation. For preventing the oversteer condition, a command for reducing the engine torque is output. On the other hand, for preventing the understeer condition, the engine torque is limited in accordance with a permissible engine torque value that is calculated on the basis of a road-surface friction coefficient, and ground loads and lateral tire forces of individual wheels. If it is detected that engine braking is in operation, the engine torque is adjusted to substantially zero.

  • Patent number: 8055420
    Abstract: A main controller calculates permissible driving forces of individual wheels from a road-surface friction coefficient, ground loads of the individual wheels, and lateral forces of the individual wheels. The main controller then calculates a permissible engine torque on the basis of the calculated permissible driving forces so as to limit engine output. In addition, based on the calculated permissible driving forces, the main controller calculates a transfer-clutch torque for front-rear driving-force distribution control, a rear-wheel torque shift amount for left-right driving-force distribution control, and a steering-angle correction amount for steering-angle control.
