摘要:
A method of operating a vehicle drive train (1) comprising a combustion engine (2), a turbo charger (22) assigned to the combustion engine, a mechanism for the injection of additional compressed air into an air intake system (8) of the combustion engine (2), a start and shift clutch (60), and a transmission (62). To optimally prepare and execute a start procedure of such an equipped vehicle, additional compressed air is only injected into the air intake system (8) of the combustion engine (2) if, depending upon the actual operating situation of the vehicle, the injection of additional compressed air benefits the safety of the driver, fuel consumption, drive comfort and/or the clutch wear.
摘要:
A method for detecting fault in an actuator. By transmitting a control value, which is generated by a control unit, to an input of the actuator a signal for the measured actuator position is produced at the output of the actuator. The signal for the measured actuator position is sent to an input of a signal conditioning unit which determines from it a measure of actuator movement. The control value is also transmitted to an input of a modeling unit, which calculates from it an expected measure of actuator movement. These movements are sent to a computer unit, which produces a corresponding status signal for the functionality of the actuator and for the functionality of the sensor for determining the actuator position.
摘要:
The invention involves a procedure for adaptive configuration recognition after the run-up of a control device with or without configuration storage, which performs an automatic and operator-assisted, optimal configuration of the operating software of a motor vehicle.In a first variant, a central control device, after its run-up, receives at the earliest possible time, as a rule after activation of the ignition, identifying information from other components connected directly or indirectly to the central control device by data link. Upon receipt of the identifying information of a component, the central control device assumes that this component is present. Otherwise it assumes that it is not present. An additional configuration memory area is envisioned in a second variant in which the central control device, after the first receipt of the identifying information of a component, stores either the information, the associated software parts, or the software configuration resulting from the total of the recognized components. In this way, the appropriate software configuration can be quickly made available upon the new start of the vehicle with an unchanged hardware configuration. Furthermore, the procedure facilitates a guarantee that no error reports will be generated about components that are not present.
摘要:
A method for controlling a drivetrain including an automatically shifted starting clutch and gear-shift clutch and a transmission, with a non self-locking clutch actuator, a gear actuator for engaging and disengaging transmission gears and a control unit which generates control commands for the clutch actuator and gear actuator and transmits such commands to the actuators such that, when the vehicle is at rest and a gear is engaged and if the clutch actuator fails, the clutch does not inadvertently engage. When a transmission gear is engaged, a control command is generated and sent for the clutch actuator to disengage the clutch. Thereafter, the vehicle speed is determined and if the speed is essentially zero and the clutch begins to engage, a control command is sent to the gear actuator to shift the transmission to its neutral position.
摘要:
A method and a device with which disturbing vibrations are diminished at least in the height of their amplitude. A control and regulating device (24) and suitable sensors (34, 36, 41) activate a device (7, 11, 15, 23, 29, 30) when previously established limiting values are exceeded with regard to procedure, with which components of the motor vehicle are influenced such that the disturbing vibrations are damped or compensated.
摘要:
There are disclosed a method of and an apparatus for regulating the operation of a friction clutch or another torque transmission system in the power train of a motor vehicle. The regulation is such that the operator of the vehicle is informed of a prevailing or impending condition which entails or is about to entail damage to the system or to the entire power train. Such situation can arise in response to excessive and/or prolonged slip of abutting friction surfaces in a friction clutch, overheating of one or more parts of the system for any other reason(s), as a result of improper selection of the transmission speed for starting of the vehicle and/or due to excessive wear upon the friction linings and/or other parts. The remedial undertaking can include such regulation of the system that the ride become uncomfortable to the occupant(s) of the vehicle and/or automatic elimination of the cause(s) of unsatisfactory torque transmission.

摘要:
The invention concerns a method for controlling a motor vehicle (2) with an automatic transmission (6) and an automated clutch (8), with a control unit (20), a drive or accelerator pedal (32), an element (30) for determining the position of the drive or accelerator pedal, and an actuating device (28) for selecting an operating mode of the motor vehicle (2). According to the invention, when the actuating means (28) is operated the position of the drive or accelerator pedal (32) is noted or evaluated, and actuation of the clutch (8) is prevented until a change in the position of the drive or accelerator pedal is recognized.
