摘要： A hydrostatic traction drive includes a first hydraulic machine that is coupled to a drive unit. The first hydraulic machine is hydraulically arranged in a hydraulic circuit with a second hydraulic machine. The second hydraulic machine has a drive shaft that is connected in a rotationally fixed fashion to a lockable differential. The traction drive has a control unit that is configured so as to control at least one measure for traction control as a function of a rotational speed of the second hydraulic machine. The at least one measure includes one or more of a measure for detecting a loss of traction and a measure for overcoming the loss of traction. A method for controlling the traction drive includes eliminating a loss of traction of the traction drive with use of the control unit as a function of the rotational speed of the second hydraulic machine.

摘要： A hydrostatic continuously variable transmission includes a fixed capacity hydraulic pump and a variable capacity hydraulic motor, connected by a hydraulic closed circuit. A control system and method for the variable transmission provides a good deceleration feeling when going downhill. In accordance with the control system and method, a range of a selected gear is determined. Next, it is determined whether the vehicle is in an automatic gear shift mode. If these conditions are met, it is then determined whether or not certain criteria for descent control are satisfied. The certain criteria may include: (1) whether the throttle is closed; (2) a speed or acceleration of the vehicle; (3) whether the acceleration exceeds a threshold; and (4) whether simultaneous satisfaction of conditions (1)-(3) exist for a period of time exceeding a fixed time. If all of the criteria are satisfied, the gear ratio is shifted by a specified amount towards a LOW side. Therefore, when driving downhill, the vehicle is not subject to acceleration greater than a predetermined value.

摘要： A method of diminishing shift shock in a stepped shift mode in a continuously variable transmission. A continuously variable transmission having an automatic shift mode and a stepped shift mode possesses a shift shock diminishing control function. In this control, when shift-down is made in the stepped shift mode (S.1), a timer is allowed to start counting (S.2) and the magnitude of deceleration G during change of the change gear ratio by a control motor is compared with a threshold value (S.4), and if the deceleration magnitude is larger than the threshold value, the supply of electric power to the control motor is stopped for only a very short time to decrease the deceleration G, thereby diminishing the shift shock (S.5).

摘要： A continuously variable transmission is controlled using a target acceleration map which contains values of target accelerations corresponding to a plurality of values of a first indication (e.g., the amount of depression of an accelerator pedal or the engine throttle opening) representative of the driver's intention for acceleration or deceleration and a plurality of values of a second indication representative of speeds of the motor vehicle. The target acceleration map is arranged such that when each of the values of the second indication is constant, each of the values of the target acceleration increases as the value of the first indication increases, at a rate which is greater if the first indication is smaller. From such a target acceleration map, a target acceleration is determined on the basis of the actual values of the values of the first and second indications at the time, and the speed reduction ratio of the transmission is controlled so that the target acceleration is achieved. In the target acceleration map, the cruising speed of the motor vehicle varies linearly as the values of the first indication vary.
