    摘要: A control system for a continuously variable transmission and continuously variable transmission wherein such is utilised, includes a drive belt located between pulley discs of a first pulley and of a second pulley, the pulleys being rotatable at a rotational speed and being operable by a first and a second piston/cylinder assembly respectively. The control system controls the respective cylinder pressure in the first and second piston/cylinder assemblies, at least based on a torque signal representing the torque to be transmitted by the transmission and two speed signals representing the rotational speeds of the first and second pulley, for clamping the drive belt between the discs thereby enabling torque transmission between the pulleys and the drive belt.

    摘要: The invention relates to a control circuit for generating a control signal (I) for controlling the transmission ratio adjustment of a belt transmission continuously adjustable with respect to its transmission ratio. The belt transmission includes a drive end (7), an output end (8) and a primary valve (15) for adjusting the transmission ratio. The primary valve (15) is driven by the control signal (I). The control circuit includes means for generating the control signal (I) in dependence upon operating parameters of the vehicle transmitted to the control circuit. It is suggested that the control signal (I) is generated in dependence upon a value (y) for a desired speed of the transmission ratio change or from a quantity derived therefrom. The value (y) for the desired speed of the transmission ratio change is determined from the operating parameters transmitted to the control circuit.

    摘要: The invention proceeds from an arrangement or a method for adjusting the transmission ratio of a continuously variable belt transmission having a drive end and an output end. The drive end and the output end have at least one axially displaceable element which has essentially the form of a conical disc. Via sensor means, an rpm signal is detected, which represents the rotational movement of the drive end or the output end, and, on the other hand, a displacement signal is detected which represents the axial displacement of at least one of the axially displaceable elements. The essence of the invention is that means for adjusting the transmission ratio are provided with the aid of which the adjustment takes place at least in dependence upon the detected displacement signal. An advantage of the invention is that, in this way, the possibility is provided to save one rpm sensor. Furthermore, and as shown in the course of the description in greater detail, the total transmission ratio adjustment is substantially independent of the engine load or of the drive torque acting in the drive train.

    摘要: The invention concerns a method and a drive arrangement for controlling an internal combustion engine, said internal combustion engine acting via a variable transmission, particularly a continuously variable transmission, on drivable wheels or the like of a motor vehicle, in which a fuel feed to the internal combustion engine is at least reduced in dependence on an operating state and the internal combustion engine operates in overrun mode and a gear ratio of the transmission is adjusted, independently of driver intention, in dependence on at last one operating parameter of the motor vehicle. It is provided that during overrun operation of the internal combustion engine (12), the gear ratio is controlled in such a way as to maximize the time interval for which the internal combustion engine (12) operates in the overrun operating state.

    摘要: The invention relates to an adjustment of the transmission ratio of a transmission having a primary end and a secondary end. The transmission is continuously variably adjusted with respect to its transmission ratio and is mounted between a vehicle engine and the drive wheels. According to the invention, means are provided by means of which a deceleration state of the vehicle of a pregivable or pregiven extent is determined. The output rpm of the vehicle engine is adjusted or controlled in dependence upon the detected rpm of the primary end in response to the determination of one such deceleration state. With the invention, it can be ensured that the vehicle with a CVT transmission comes to standstill for a transmission ratio close to the start transmission ratio even for especially intense decelerations at low speeds (30 to 60 km/hour). Furthermore, the engine can be fired with fuel in order to increase the volumetric displacement of the hydraulic pump without the problem that the vehicle engine applies power to the wheels which opposes the braking action.

A variator controller (16) is assigned to the automatic transmission stage (17) and a contact-force control (18) is assigned to the clutch (19). Depending upon the detected and classifiable drive situations, first and second torque/contact-force reserves (13, 44) are determined which are supplied to an input quantity ME (22) of the variator controller (16) and to the contact-force control (18) for the clutch (19). The output signals (20, 21) of the variator controller (16) and the contact-force control (18) influence the operation of the automatic transmission stage (17) and the clutch (19).

    摘要: The invention relates to an arrangement and a method for determining the transmission ratio of a continuously variable transmission having a drive end and an output end. A signal, which represents the transmission ratio, is computed in dependence upon a primary rpm of the drive end and a secondary rpm of the output end which are transmitted to the arrangement. A fault signal is generated which is dependent upon the instantaneous primary rpm and/or the instantaneous secondary rpm and indicates whether a value for the transmission ratio is to be outputted as the signal representing the transmission ratio. This value is computed from the detected instantaneous values for the primary rpm and the secondary rpm.
