ABSTRACT:
A control arrangement for a four-wheel drive vehicle which has at least one gear box or differential with controllable power transmission characteristics having circuitry for producing control signals in response to vehicle operating conditions and parameters. The arrangement allows for control of the distribution of torque to the respective wheels of the vehicle as a function of a selected number of parameters, such as relative or average wheel speed, engine speed, gas pedal or throttle valve angle, etc. The arrangement contemplates the simultaneous control of more than one adjustable gear box or differential as a function of commonly and/or separately sensed parameters.
