    摘要: A method of estimating a load on a vehicle (10), the method comprising: obtaining a first load estimate using a first load estimation technique; obtaining a second load estimate using a second load estimation technique; analysing characteristics of the first load estimate and the second load estimate; and, based on the analysis selecting either the first load estimate or the second load estimate as an output load estimate.

    摘要: A transmission control system of a vehicle includes an estimated acceleration module and a pressure control module. The estimated acceleration module determines an estimated longitudinal acceleration of the vehicle based on a force at axles of the vehicle corresponding to engine torque, a braking force imposed by mechanical brakes of the vehicle, an aerodynamic drag force of the vehicle, and a road load force imposed on the vehicle by contact between tires of the vehicle and a road surface. The pressure control module, when a measured longitudinal acceleration of the vehicle is negative and the estimated longitudinal acceleration is greater than the measured longitudinal acceleration of the vehicle, adjusts transmission fluid pressure applied to one or more clutches of the transmission and shifts the transmission to neutral.

    摘要: In vehicles designed to pick up and process crops, drive units affect the ground drive, which is an all-wheel drive, which acts on all of the wheels and/or track roller unit in contact with the ground, electronic controls and actuators perform the control and regulation of the drive units, and control units that control the drive torque at the wheels are used to obtain good traction and minimal slippage of the wheels on the ground. To control the drive torques, sensors are used at particular points, the signals and data of which are processed by the control device in order to predetermine a torque or intake volume requirement. The preselection of torque in the control results in the intake volume of the hydraulic drive motor being regulated. By specifying the intake volume required, it is possible to obtain optimal traction at one or more drive wheels, and to prevent undesired slippage of any one drive wheel in advance.

    摘要: A method for control of a vehicle gearbox which is automatically controlled by a control system. The control system's choice of transmission ratio is influenceable by the vehicle's driver. The control system chooses an initial transmission ratio for moving off stationary. The method includes determining a first initial transmission ratio by using the control system, and determining a second initial transmission ratio indicated by the vehicle driver. The gearbox is set to the second initial transmission ratio indicated by the driver when the second ratio is higher than the first initial transmission ratio determined by the control system.
