The control operates by regulating slip of a clutch during change of gear ratio. A target speed for the input shaft is computed (102) and the coupling across the clutch determined (110). The coupling is controlled by adjustment of engine torque which is combined (112) with an estimate (108) of the slip required to cause the speed of rotation of the input shaft to track the engine speed.;

An orientation angle detector using gyroscopes (301-303) for detecting X-, Y- and Z-angular velocities which are time-integrated (60) to produce pitch, roll and yaw angles (gamma, beta, alpha) of the orientation. Two accelerometers (403, 404) are used to obtain tentative pitch and roll angles in order to correct the pitch and roll angles, and two terrestrial magnetometers (401, 402) are used to ob...

An automated transmission disengages clutch 14 for gear engagement upon movement of lever 24 from neutral N to drive S and in a first, standard start mode, controls clutch re-engagement according to engine speed. The system also includes a vehicle brake 58 actuation sensor 56 and a switch for initiating a second, racing start, mode following actuation of the brake 58 and the switch, to permit incr...

The invention concerns a multimode transmission device. The invention also concerns a vehicle using such a device. The inventive device essentially comprises parallel kinematic paths (3, 4, 7, 8) and a control device (C) for changeover of transmission modes which operates so that the duration of the mode changeover is reduced to a minimum while preserving the continuity of the torque to the wheel ...

The method for starting the vehicle fitted with an automatic transmission, an input clutch and a heat engine controlled by a computer is initiated by the detection (a) of the desire to start the vehicle and closed by the total closure (f) of the clutch.
