Re: Smart awd
Real time four-wheel drive systemHonda's Real Time 4WD system on the CR-V utilizes a dual hydraulic pump center/rear differential and 4WD transfer case. The dual pump system employs two pumps, one driven by the drive shaft from the transfer case at the front of the vehicle, and the other driven by the rear differential. When there is a pressure difference of greater than 3% between these two pumps, a clutch that connects the front and rear axles begins to engage. The greater the difference in axle speeds, the more torque is applied to the rear. This system would most accurately be called "automatically engaged four wheel drive,"[according to whom?] because the driver has no control over when the system engages. To allow the ABS braking system to function properly, the 4WD clutch will disengage if the brakes are applied. The B20Z engine sends 52% of the torque to the rear wheels or whichever wheel has the most traction.
