Abstract
Preventing loss of vehicle control under drive conditions is analogous to, and as important as, the retention of vehicle control under emergency braking. Loss of control under drive conditions frequently leads to panic braking, which only aggravates an already dangerous situation.
A four-wheel-system for passenger cars is described, having as its special aim greatly improved controllability under all road surface conditions.
Reasons are given for splitting the torque unequally between the front and rear axles, and for employing two spin control clutches geared in parallel to the center differential in such a manner as to modify the basic torque split.
