A device delivers a torque setpoint signal applicable to the vehicle wheels of a motor vehicle including an automatic transmission. The torque setpoint signal has static and dynamic components that are set according to input data supplied by an input unit and based on a recorded list of parameters representing the driver's will, the motor vehicle state, and the environment thereof. The device includes a first unit for computing the dynamic component of a gross torque, a second unit for computing the static component of a gross torque, the second unit being connected to the output of the first unit, and a unit for adaptation to a brake situation producing the static component of the torque adapted to the braking situation according to the list of parameters.

Method for producing a control instruction adaptable to a brake situation for a transmission device of a motor vehicle power train and corresponding device

An automatic transmission of a power train for a motor vehicle capable of producing a set operating speed and a set power train control to attain an engine speed, according to a torque applied to wheels that is adapted to wishes of the driver. The device includes: an input unit that furnishes input data; a control unit having at least two modules according to two distinct driving modes, an automatic mode and a manual mode with pulse control; a processing module for processing signals furnished by a motor vehicle speed control; a selection module that receives signals from the processing module and from the motor vehicle speed control and capable of furnishing a selection signal (mode).

Method and device for controlling an automatic transmission for a motor vehicle

A device for controlling an automated transmission of a motor vehicle engine-transmission unit capable of delivering a torque setpoint signal to be applied to the motor vehicle wheels, including two static and dynamic components, produced based on input data delivered by an input unit including a recorded list of parameters representing the driver's wishes, the motor vehicle state, and the motor vehicle surroundings. The device includes a first unit capable of calculating a dynamic torque component not adapted to a cornering situation; a second unit capable of calculating a static torque component, connected to the input of the first unit; and a unit for adaptation to the come in situation delivering a static torque component adapted to the cornering situation in accordance with a list of predetermined input parameters.
