Abstract: The invention is directed to a method and an arrangement for controlling a drive unit (1) of a motor vehicle. The method and arrangement reduce the lost motion of an operator-controlled element (5), which is actuable by the driver, up to an increase of the road speed of the vehicle beyond the road speed pregiven by the road speed controller (10). The degree of actuation (F) of the operator-controlled element (5) is detected and a desired value (S) for the torque of the drive unit (1) is formed from this degree of actuation (F). The desired value (S) for the torque is compared to a pregiven value (V) for the torque requested just then by the road speed controller (10). The torque of the drive unit (1) can only then approach the desired value (S) via control of the drive unit (1) when the desired value (S) exceeds the input value (V). The course of the desired value (S) for the torque is selected as a function of the degree of actuation (F) of the operator-controlled element (5) so that a pregiven value (VW) for the degree of actuation (F) of the operator-controlled element (5) is not exceeded at an intersect point (SP′) of the course of the desired value (S) for the torque and the input value (V) just then requested by the road speed controller (10).

Abstract: A locomotive monitoring system defines several mutually exclusive operating states for a locomotive. The amount of time the locomotive operates in each state is preferably determined and recorded. This recorded information can then be evaluated with a view towards improving locomotive operations. For example, a plurality of mutually exclusive idle states can be defined and monitored to determine how long a locomotive idles under certain conditions instead of automatically shutting down for the purpose of conserving fuel. In this manner, the sources of lost fuel savings can be readily identified, quantified and addressed. An event log is also provided for chronicling certain operating events of interest over time, such as those relating to the starting, stopping and/or idling of the locomotive's engine.

Abstract: A method of regulating the position of a clutch actuator in a vehicle employs the concept of adapting the servo-loop parameters of a position controller of the clutch to different operating conditions of the vehicle, as well as the concept of applying and continuously adapting a bias current of the actuator motor in order to avoid or minimize the incidence of a hunting or after-regulation behavior of the control loop and to thereby minimize the energy consumption of the actuator motor.

Abstract: A correction coefficient setting unit calculates as a difference in an actual revolution speed the difference between the actual revolution speed of a front driving axle and the actual revolution speed of a rear driving axle. Moreover, the correction coefficient setting unit calculates the ideal reference revolution speed of the front driving axle and the ideal reference revolution speed of the rear driving axle in consideration of a difference in a radius of gyration between the driving axles. The correction coefficient setting unit also calculates as a difference in a reference revolution speed the difference between the ideal reference revolution speed of the front driving axle and the ideal reference revolution speed of the rear driving axle. The correction coefficient setting unit then corrects a previous correction coefficient relevant to a transfer clutch set in the basic clutch tightening force correction unit according to the difference in an actual revolution speed and the difference in a reference revolution speed.

Abstract: A driving force control system for a four-wheel drive vehicle. An automatic-mode transmitted torque is calculated based on operating conditions of the vehicle. When lock mode-executing conditions including operation of a lock switch by the driver are satisfied, a lock mode in which the engagement forces of the clutches are set to a lock-mode transmitted torque, including a lockable transmitted torque which can lock the front wheels and the rear wheels to each other. Further, the lock mode transmitted torque is limited depending on a traveling condition of the vehicle such that the lock-mode transmitted torque is held below the lockable transmitted torque. When the automatic-mode transmitted torque is larger than the limited lock-mode transmitted torque during the lock-mode, the engagement forces of the clutches are set to the automatic-mode transmitted torques.

Abstract: A lock-up control system for an automatic transmission including a torque converter and a lock-up clutch. The lock-up control system comprises an accelerator pedal depression amount sensor for detecting a depression amount of an accelerator pedal, and a controller. The controller includes an accelerator pedal movement speed calculating section for calculating a movement speed of the accelerator pedal. The controller includes a lock-up control section adapted to disengage the lock-up clutch in a condition in which a driving point of the vehicle is within a lock-up condition releasing region in a set lock-up schedule, and to engage the lock-up clutch in a condition in which the driving point is within a lock-up condition applying region. The lock-up control section includes a first lock-up releasing control section adapted to gradually disengage the lock-up clutch from an engaging state and put the lock-up clutch into a disengaging state when the accelerator pedal movement speed is not lower than a set speed and an initial accelerator pedal depression amount in the accelerator pedal depression amount is not smaller than a set accelerator pedal depression amount to establish a driving condition of the vehicle under the engaging state of the lock-up clutch.

Abstract: The invention proceeds from a vehicle having a clutch and a transmission. The clutch is mounted in the drive train of the motor vehicle and the transmission is mounted in the drive train and is changeable with respect to its transmission ratio. Furthermore, means are provided which generate a clutch signal which represents the actuation of the clutch. The essence of the invention is that a change of the transmission ratio is detected. According to the invention, monitoring means are provided by means of which a fault signal is generated in dependence upon the recognized change and the generated clutch signal. The fault signal indicates whether the means, which generates the clutch signal, operates properly. A further variation of the invention evaluates the clutch actuation with the first start of movement of the vehicle after the engine start.

Abstract: The invention is directed to a system for controlling a clutch which is arranged between the motor of a vehicle generating a motor torque and the wheels of the vehicle. With this clutch, and in response to a drive signal, the force flow between the motor of the vehicle and the wheels can at least be reduced. The essence of the invention is that the drive signal of the clutch is formed in dependence upon a signal which represents a change of the motor torque of a specific extent. The invention is also directed to a system for controlling the motor of a vehicle with an adjusting element for influencing the motor torque which can be adjusted at least in dependence upon the detected command torque. When a specific extent of a change of motor torque is present, the execution of the command to adjust the motor torque is delayed. The essence here is that a clutch is arranged between the vehicle motor and the wheels of the vehicle and the delay is actuated in dependence upon a status signal representing the instantaneous operating state of the clutch.
