摘要： A method for anticipating downshifting upon uphill driving on a vehicle including an automatic transmission and including change laws imposing a change to a lower gear based on pre-established downshifting curves. The method imposes a change to the lower gear to the transmission independently from the gear set point established by the change laws when the acceleration that can be reached at the maximum torque on the current gear is lower than an acceleration threshold necessary for maintaining the vehicle speed.

摘要： Method of recognizing and managing the unavailable gear ratios of an automatic gearbox, and associated system. The method for controlling the gear ratios of a motor vehicle fitted with an automatic gearbox involves receipt (101) of a requested gear ratio instruction. The method involves receipt (102) of information relating to the gear ratios that are unavailable and determining the gear ratio that needs to be applied to take account of the gear ratios that are unavailable.

摘要： A device for evaluating the transverse acceleration of a motor vehicle comprises means (6, 7) of measuring the rotational speeds of two wheels of the vehicle and a module (D3) for estimating the transverse acceleration of the vehicle from these speeds. It further comprises a validation module (2) able to calculate, as a function of vehicle operating parameters, particularly of the rotational speeds of the said wheels and of the transmission ratio engaged, a Boolean slip variable which is negative if the transverse acceleration estimated by the module is relevant for detecting a bend, and which is positive if the reverse is true.

摘要： A system for controlling a motor vehicle automatic transmission comprises a means of estimating engine torque and a means of estimating vehicle acceleration, a map (3) of the resistive forces to which the vehicle is subjected as a function of its speed, stored maps of gear shifts suited to various road profiles, and a system (1) for selecting configured gear shift laws in order, using the said engine torque, the said acceleration and the said map of resistive force, to determine the current slope of the road surface along which the vehicle is moving. The said system for selecting the gear shift laws comprises a filter (4) delivering a mean value of this current slope, and the said gear shifts law selection system is configured to impose on the transmission at least one ascent gear shift law if the current slope is steeper than a first threshold (S3), at least one horizontal terrain gear shift law if the current slope and the mean slope value are respectively lower than a second threshold (S2) lower than the first and lower than a third threshold (S1) lower than the second, and at least one intermediate gear shift law that is somewhere between the ascent law and the horizontal terrain law if the current slope is less than the second threshold (S2) and, at the same time, the mean value of slope is greater than the third threshold (S1).

摘要： A device for controlling an automated transmission with discrete gear ratios of a motor vehicle power plant able to preposition at least one transmission system operating parameter as a function of the next gear change to be performed, comprises a means (1) of estimating the gradient (P) of the road surface along which the vehicle is running, and comprises a stored map (9) linking the accelerator instruction, the gradient (P) of the road surface, and the sign of the actual acceleration of the vehicle. The device comprises a logic processor (3) which continuously delivers a Boolean upshift variable signalling a forthcoming upshift or downshift in transmission ratio, as a function of which Boolean variable the said operating parameter is prepositioned.
