Definitions
- the invention relates to a method for starting or holding a vehicle on the mountain according to the preamble of claim 1.
- the brakes must be released so that the power transmission torque can be transmitted from the clutch to the wheels.
- the object of the invention is to develop a method for starting a vehicle on the mountain, with which the clutch is protected against overheating and thus against excessive wear during the operation of at least one brake and simultaneous depression of the accelerator pedal. This object is achieved by a method having the features of claim 1.
- a torque is transmitted from a drive motor, which is in communication with an engine control unit for electronic torque control, to the automated clutch associated therewith.
- the force acting on the vehicle downgrade force is counteracted by the use of the foot and / or parking brake.
- the torque request request is triggered only to the controller when at least one brake is actuated.
- the torque reduction is realized via an electronic ramp.
- FIG. 1 shows a schematic representation of a drive train of a vehicle
- FIG. 1 the drive train of a vehicle is shown schematically.
- an engine 10 is connected to a clutch 12 and a transmission 14, wherein the output shaft of the transmission 14 via a propeller shaft 16 and a differential 18, the rear wheels 20 of the motor vehicle drives.
- a conventional friction clutch is shown as the clutch 12, the actuating lever is actuated by a clutch actuator 22, for example an electric motor.
- the transmission 14 may be, for example, an automated manual transmission, the switching member of which can be actuated by a gear actuator 24 for selecting and shifting a gear.
- the gear actuator 24 contains two electric motors.
- a transmission control unit 26 To control the clutch actuator 22 and the gear actuator 24 is a transmission control unit 26, whose inputs with sensors for detecting the position of the Kupplungsaktors 22, the transmission actuator 24 a sensor 28 for detecting the position of a Gereteapportionlhebels 30, wheel speed sensors, such as the sensors 36 shown for the Rear wheels and possibly other sensors are connected.
- the transmission control unit 26 includes a microprocessor and memory devices in which programs are stored, according to which the actuators 22 and 24 are controlled depending on the input signals.
- an engine control unit 40 is provided, whose inputs with a sensor 42 for detecting the position of an accelerator pedal 44, a sensor 46 for detecting the position of a brake pedal 48, a sensor for detecting the rotational speed of the crankshaft of the internal combustion engine, a sensor for Detecting the position of an actuator 50 for adjusting a power actuator 52 of the internal combustion engine, a sensor 54 for detecting the internal combustion engine incoming air flow, a sensor 56 for detecting the temperature of the internal combustion engine and possibly other sensors are connected.
- An output of the engine controller 40 controls the actuator 50 to operate the power actuator (throttle) of the engine.
- the controllers 26 and 40 are interconnected via a bus line 58 so that data can be transferred between the controllers 26 and 40.
- the clutch 12 is required according to a stored example in the transmission control unit 26 characteristic that indicates the respective transmissible clutch torque depending on the position of the actuator of the clutch or the clutch actuator 22.
- the clutch actuator 22 is controlled such that the clutch 12 with a predetermined, up to a maximum value, which is dependent on the position of the accelerator pedal 44, an increasing Transmitting torque
- the prime mover 10 such - A - is controlled that it rotates with a predetermined, dependent on the position of the accelerator pedal 44 Anfahrsollspeed, which corresponds to a starting speed, which results in Vietnameseschlupfender clutch 12 to a corresponding desired approach speed.
- FIG. 2 shows the method according to the invention with reference to a flowchart.
- the current engine rotational speed determined by the sensor and the angular position of the pedal from sensor 42 are forwarded to control unit 40.
- the torque reduction request is initialized at a value that is greater than the maximum engine torque. This protects against a sudden torque change caused by too low a preset.
- a torque increase request is calculated from the current input values. Subsequently, it is determined in step 65 whether the torque increase request is activated.
- this torque increase request is sent to the control unit 40 in step 110. If, however, the activation of the torque increase request is denied in step 65, a torque reduction request is calculated in step 70. Subsequently, a query takes place in step 75 to the effect whether a brake is actuated or not. If this query indicates that at least one brake is pressed, a limit value for the brake holding torque is calculated. Once the desired torque reduction limit has been reached, this desired torque is maintained until the driver releases the brake pedal.
- step 80 the query connects to whether the brake holding torque is smaller than the torque reduction request or not. If this is smaller, it follows in step 90 that the torque reduction request is equal to the brake holding torque. This result of requiring torque reduction is communicated to the control unit 40 in step 100 to lower and trim the maximum engine torque to this requirement. This also limits the energy consumption in the clutch 12.
- the torque reduction takes place controllably graded to the predetermined threshold in step 80 in order to avoid a sudden lowering, which would lead to the driver perceived blows. Once the torque-down request has decreased to a value greater than that achievable by the engine, the process is restarted at step 65.
- step 75 If, however, the queries in step 75 indicate that neither a brake is pressed nor that in step 85 the current brake holding torque is less than the desire for a torque reduction, this information is transmitted to the control unit 40 in step 100.
