摘要： A belt-type continuously variable transmission CVT is equipped with a belt 44 wrapped around across a primary pulley 42 and a secondary pulley 43, and a CVT control unit 81 for controlling pulley hydraulic pressures to the primary pulley 42 and the secondary pulley 43. The CVT control unit 81 determines whether an operating state is a driving state where the direction of an input torque inputted to the belt-type continuously variable transmission CVT is from a driving source (engine 1, motor generator 2) or a coasting state where the input torque direction is from front-left and front-right road wheels 6, 6. The pulley hydraulic pressure for the input torque for when it is determined that the operating state is the coasting state is set higher than the pulley hydraulic pressure for the input torque for when it is determined that the operating state is the driving state, thereby suppressing a slippage of the belt.

摘要： The present invention relates to a method when driving a vehicle (100), wherein said vehicle (100) comprises an internal combustion engine (101), wherein said vehicle (100) is arranged for being driving in at least a first mode (M
1 ) and a second mode (M
2 ), wherein, when the vehicle (100) is driven according to said second mode (M
2 ), a reduced fuel consumption is prioritized to a larger extent at the cost of performance compared with when the vehicle (100) is driven according to said first mode (Μ
1 ), wherein said vehicle (100) comprises a gearbox (103) that is settable to a plurality of transmission ratios. The method includes, when setting said gearbox (103) from a first transmission ratio to a second transmission ratio being lower than said first transmission ratio, wherein said lower transmission ratio is one of the three lowest settable transmission ratios for said gearbox (103) : - comparing a torque (T
req ) requested from said internal combustion engine after setting said gearbox (103) to said second transmission ratio with a first torque (T
lim1 ), and - driving said vehicle according to said second mode (M
2 ) if said request for torque (T
req ) from said internal combustion engine is below said first torque (T
lim1 ).

摘要： An automatic transmission control device is provided with: an automatic transmission mode for automatically shifting on the basis of a relationship between an automatic transmission shift line defined by vehicle speed, and an operating point defined by the detected vehicle speed; and a manual transmission mode for shifting on the basis of a manual operation by the driver and a relationship between a manual transmission shift line defined by vehicle speed and the detected vehicle speed itself, and controlling so as to reject an upshift operation by the driver when the detected vehicle speed is at or below a prescribed vehicle speed. The automatic transmission control device is further provided with: a shifting properties change means for changing the shifting properties of the automatic transmission in a manner such that downshifting occurs at a faster vehicle speed when the throttle opening is less than a prescribed opening in comparison to when the throttle opening is equal to or more than the prescribed opening; and a shifting properties change prohibiting/allowing means for prohibiting a change to the shifting properties until downshifting has occurred once while the manual transmission mode is selected, and allowing a change to the shifting properties after downshifting has occurred once. As a result, it is possible to improve fuel efficiency and suppress imparting an unnatural sensation to the driver.

摘要： A method and system for controlling a powertrain in a vehicle includes steps including registering a road condition. If the registered road condition corresponds to normal road conditions then a first gear selection control algorithm is used intended for driving the vehicle in a normal mode corresponding to the conditions on an ordinary road. If the registered road condition corresponds to soft surface road conditions then a second gear selection control algorithm is used intended for driving the vehicle in a soft surface mode corresponding to the conditions on an soft surface road. In this way, a vehicle can be adapted to be provided with an AMT to work in a satisfactorily way under an increased diversity of conditions.

摘要： A control system for controlling an automatic transmission
that is capable of establishing a given speed stage by engaging a given frictional element. The control system comprises an actual time lag measuring section that measures an actual time lag from the time when a speed change instruction for the given speed stage is issued to the time when a gear ratio of the automatic transmission starts to change for the purpose of establishing the given speed stage, a torque detecting section that detects a torque from an engine, a time lag map that provides a suitable time lag in accordance with the detected torque from the engine, a learning correction section that corrects, by learning control, an instruction value for the hydraulic pressure led to the frictional element in a manner to cause the actual time lag to have the same value as the suitable time lag; and a time lag map correcting section that corrects the suitable time lag in accordance with an operation condition of an associated motor vehicle.

摘要： A motor vehicle with a clutch (3) and an automated transmission (9) between the engine and the drive wheels of the vehicle. The vehicle has control elements (45,48) for engine function and transmission function depending on a set position of an electronic gear selector (46). The control elements, with the gear selector in its position for automatic shifting, selects a gear for starting off or under way, which is determined by the gear selection strategy stored in the control means as a function of various parameters fed into the control elements. The control elements, are arranged to perform, firstly, a simulation process related to the gear selection strategy with at least one alternative set of parameters (U2-UN) and, secondly; a comparative analysis based on a first set of control parameters (U1).
