Abstract
To prevent jolts or shocks interfering with smooth operation of an automotive vehicle upon disengagement of an automatic free-wheeling arrangement and reestablishment of engine braking, a control element (22, 23) is provided, controlled by the system, typically coupled to the brake light switch, which reestablishes positive drive connection between engine and wheels to permit engine braking, to reduce the torque supplied by the engine at the re-engagement instant, to thereby insure smooth transition from free-wheeling to engine braking. Preferably, the engine speed is sensed, and the speed of the shaft beyond the free-wheeling arrangement is sensed (points A, B), and engine torque is reduced just before synchronism is achieved.
