Motor vehicle speed regulating device, has regulating module to establish torque set point for output shaft of traction chain based on speed set point and measured speed, and control module to control chain with respect to torque set point

The device has a sensor (34) for measuring speed of a motor vehicle. A control unit (32) controls a traction chain with respect to the measured speed and a set point of speed of the vehicle. A regulating module (44) establishes a torque set point for an output shaft of the chain based on the point and measured speed. A control module (46) controls the chain with respect to the torque set point for corresponding torque on the shaft. Independent claims are also included for the following: (A) a motor vehicle speed regulating process (B) an information recording medium having instructions for implementing a motor vehicle speed regulating process.
