Traction control
The PDAS is a non-integral electronically controlled, hydraulically activated, mechanical locking system. This system utilises the AWD G64 transmission and the differential locks are installed into the transmission. However system failure has no affect on the normal operation of the permanent AWD. The PDAS is activated and de-activated only when required to assist in retaining traction or grip. The system was developed from the mechanically variable differential drive controlsystem used in the Porsche 959 with its Paris-Dakar transmission. The Paris-Dakartransmission was also installed into the 20 964 Carrera C4RSs assembled at the Porsche motor sports department at Weissach Germany.
System Purpose
The primary purpose of the traction control system is to enhance the advantages provided by the permanent AWD system. The traction control system is used to positively enhance the C4s handling using the already superior traction provided bythe AWD. The traction control system has two differential locks. The longitudinal (inter-axle) which provides a variable lock between the front axle and the rear axle and the lateral (transverse lock) which provides a variable lock between the two rearwheels. The lateral lock is applied to reduce the danger of oversteer from the ferraria effect while driving the C4 in curves. “Anti-spin control”. This function works very well, but it is not infallible. It is still possible to spin a Carrera 4 if the limits of the system are exceeded. The longitudinal lock is used to stabilize the C4 when it is accelerated out of a curve. If for example one axle of the C4 is on ice and the other is on a dry surface, the wheels on ice could spin during acceleration. To counter this the longitudinal lock will be activated and it will send more drive or torque to the slower turning axle (the one of the dry surface). The lock will remain engaged until equal wheel speeds are restored. The drive ratio when the longitudinal differential lock is activated can be changed infinitely from 0 to 100% or 100 to 0% in fractions of a second.
