A driving force control method controls driving force distribution to each of a first driving source connected to front wheels and a second driving source connected to rear wheels so that a pitch angle of a vehicle behaves as desired. The method includes setting a pitch rate during starting of the vehicle to a corrected pitch rate different from a predetermined basic pitch rate, wherein the basic pitch rate is determined according to basic driving force distribution for achieving desired vehicle characteristics of the vehicle, and the corrected pitch rate is determined so as to adjust a feeling of acceleration of an occupant of the vehicle according to a change in a requested acceleration of the vehicle.

Driving force control method and driving force control device

A drive apparatus for a vehicle auxiliary device is provided that basically includes first and second drive sources, an auxiliary device, first, second and third rollers, first, second and third idler rollers and a roller pair selection mechanism. The first, second and third rollers are linked to rotary shafts of the first and second drive sources and the auxiliary device. The first, second and third idler rollers are disposed at gap positions formed between the first, second and third rollers. The roller pair selection mechanisms select a power-transmitting roller pair from among the first, second and third rollers by selectively moving the first, second and third idler rollers in roller contact directions, thereby interposing the first, second and third idler rollers therebetween.

Drive device for vehicle auxiliary machine

A torque distributor includes a friction-drive mechanism having a first roller rotatable together with a first rotary member, partly constituting a torque-transmission path to primary drive wheels, and a second roller rotatable together with a second rotary member, partly constituting a torque-transmission path to secondary drive wheels. Also provided is an eccentric-crank mechanism for revolving the second roller in a direction opposite to a rotation direction of power transmission of the second roller around an eccentric-shaft axis displaced from a second-roller rotation axis to produce a displacement of the second roller from a non-power-transmission position of non-frictional-contact with the first roller, thereby ensuring high-precision torque-distribution control with no reversal of a polarity of moment acting on a rotational-position-control system for eccentric cranks.
