摘要： According to one embodiment of this disclosure, a vehicle having an electric machine and at least one controller is described. The electric machine may be configured to generate creep torque to move the vehicle. The controller may be programmed to decrease a target speed of a torque converter impeller to create a desired brake torque and partially cancel the creep torque without application of friction brakes in response to a brake pedal being pressed while an accelerator pedal is not being pressed.

摘要： A speed control system for a hydrostatic transmission includes an engine having a drive shaft connected to a hydraulic pump. At least one hydrostatic motor is connected to the pump in a closed circuit by a flow line. Connected to the motor via a system shaft is a vehicle system. A controller is connected to a plurality of sensors and a proportional high pressure relief valve that is connected to the flow line between the pump and the motor. Based on information received from the sensors, the controller sets the pressure relief valve to limit the pressure to a valve that will not over-speed the engine and allows the demands of the speed control system to be attained. This may be accomplished through the use of various algorithms.

摘要： An ECU includes: an engine control unit that controls devices provided for an engine on the basis of a target engine rotational speed; and an engine model that calculates the target engine rotational speed such that the target engine rotational speed varies in accordance with a target engine torque and an actual engine rotational speed in a steady state, and that calculates the target engine rotational speed such that the target engine rotational speed varies in accordance with the target engine torque independently of the actual engine rotational speed in a transient state in which the engine is unstable as compared with the steady state. When the engine is controlled by the thus configured ECU, the control accuracy is improved.

摘要： During reversal of drive of a vehicle, particularly a work machine with a hydrodynamic torque converter and a bypass clutch, the bypass clutch is first disengaged, during the reversal process. Next, a previously engaged first driving direction clutch, driving the vehicle in the first driving direction, is disengaged and a second driving direction clutch, for driving the vehicle in the second driving direction, is engaged so that a speed of the vehicle, in the first driving direction, is reduced and a speed of the vehicle, in the second driving direction, is subsequently accelerated, whereby the drive motor is operated at a higher rotational speed during the reversal process.
