  • Patent number: 9889745
    Abstract: A slip determination system for a vehicle, which is capable of improving the determination accuracy by avoiding erroneous determination of excessive slip of wheels when a state of the wheels, driven/braked by motors, is switched. In the slip determination system according to the present invention, when first and second motor rotational speeds NMOT1 and NMOT2, which are rotational speeds of rear motors which brake/drive rear wheels WRL and WRR, reach a reference rotational speed NMREF set based on wheel rotational speeds NWFL, NWFR, NWRL, and NWRR, it is determined that excessive slip has occurred in the rear wheels WRL and WRR. When the sign of a target torque TROBJ of the rear motors is inverted, the reference rotational speed NMREF is changed to a value more difficult to be reached by the first and second motor rotational speeds NMOT1 and NMOT2, or the excessive slip determination is inhibited.

  • Patent number: 9389616
    Abstract: Provided is a driving force control device for a four-wheel-drive vehicle that can evade an occurrence of excessive understeer and oversteer in situations unintended by the driver, by appropriately controlling driving forces to be distributed to sub-drive wheels. The driving force distribution device of the four-wheeled vehicle controls driving force to be distributed to the rear wheels (Wr, Wr) by the clutch (10) for front-and-rear torque distribution so that the wheels (Wf, Wf) are main drive wheels and the rear wheels (Wr, Wr) are sub-drive wheels. The driving force distribution device is adapted to perform control to restrict the upper limit of the four-wheel drive torque based upon an estimated driving force and steering angle of the vehicle, when calculating four-wheel drive torque to be distributed to the rear wheels (Wr, Wr) by the driving force distribution device (10).

  • Patent number: 9376006
    Abstract: Provided is a vehicle provided with left and right electric motors electrically connected to a battery and mechanically connected respectively to left and right vehicle wheels, a power generator mechanically connected to an internal combustion engine being electrically connected to the battery, wherein the battery is reliably protected during traction control and at other such times. Two electric motors, specifically first and second electric motors, are temporarily handled integrally to determine a torque down amount (TD), which is the total allowable power variation width (?) of the two electric motors, on the basis of left and right total power (Y), and the respective motive powers of the first and second electric motors are controlled while being limited by values obtained by simply dividing the determined torque down amount (TD) equally, whereby the allowable input/output power (allowable input power (Z)) of the battery is reliably protected.
