    摘要: To provide a four-wheel drive system which improves running performance of an automotive vehicle by inhibiting a driving torque from becoming insufficient upon occurrence of a slip.An R slip sensing means of a DC motor torque calculating means senses a slip due to a spin of rear wheels. When the rear wheel slip is sensed, an R slip DC-motor-torque correcting means corrects a torque of the rear wheels so that a driving force of the rear wheels is reduced and then increased. The R slip DC-motor-torque correcting means reduces a driving torque of the rear wheels to eliminate the slip and holds the reduced driving torque until the slip is eliminated, and then increases the driving torque to a value lower than a value which the driving torque has taken at the time of occurrence of the slip. The driving torque is increased to a predetermined limit value depending on the number of slips.

    摘要: A controller for an electric four-wheel-drive vehicle, which can ensure smooth running performance of the vehicle, an electric driving system, and an electric four-wheel-drive vehicle using the controller. A first wheel is driven by an engine, a second wheel is driven by a motor, and a driving force of the engine is transmitted to the first wheel through a manual transmission and a clutch. When the clutch is in a partially engaged state, a controller (4WDCU) receives an input signal representing a degree of engagement of and clutch and outputs a signal to control a driving force of the motor in accordance with the input signal. When the vehicle starts running and no slips occurs in the wheels, the 4WDCU outputs the signal to gradually increase the driving force of the motor as the engagement of the clutch is progressed.

    摘要: A differentiator calculates the acceleration of the rear wheels. An acceleration threshold calculation means enable the skid-detection acceleration threshold to be adjusted corresponding to the conditions of the vehicle. An acceleration skid-detection means make a comparison between the acceleration of the wheels obtained by the differentiator and the skid-detection acceleration threshold adjusted by the acceleration threshold calculation means, and determine whether or not a skid of the wheels has occurred, based upon the comparison result. Such an arrangement provides a vehicle driving force system having a function of detecting a skid even in a case that a skid of the wheels has occurred at a low acceleration of the vehicle.
