Definitions
- the invention relates to a method for detecting the presence of a driver in a motor vehicle, in particular with an automated manual transmission, wherein the operation of predetermined by a driver usually operated controls of the motor vehicle is detected by electrical signals from a control device.
- the signal transmission can be effected by a data BUS, in particular a CAN-BUS but also digital, analog or by PWM.
- DE 102 16 547 A1 describes a method in which a driver presence signal is only generated by a control device when the actuation of at least one of the operating elements normally actuated by a driver is detected.
- the presence of a driver presence signal is a precondition for the fact that certain vehicle functions can be activated, in particular the closing of the clutch.
- the signal transmission takes place here by a data bus, in particular a CAN-BUS, in order to be able to transmit as many signals as possible over a few lines.
- a data bus in particular a CAN-BUS
- the driver recognition takes place by means of at least one further redundantly detected driver-typical signal, a reliable driver recognition can also be carried out in the event of faulty or failed signal transmission.
- a particularly secure driver recognition is achieved if at least two redundantly transmitted driver-typical signals detected within a predetermined first time interval become.
- the time duration of the first time interval is preferably chosen so short that the detection of two driver-typical signals due to a hardware error or accidental operation is very low or almost impossible.
- the driver recognition is preferably carried out by detecting typically driver-redundant transmitted driver signals in the vehicle, such as. by detecting a first redundant signal when changing the position of the selector lever for switching gears of the motor vehicle transmission and by detecting a second redundant signal upon actuation of the vehicle brake within the predetermined first time interval.
- the change in the position of the accelerator pedal may be detected by a redundant signal.
- a driver detection is preferably carried out by detecting a first redundant signal upon actuation of the selector lever from a neutral or Parklace in a forward gear or in a reverse gear and by detecting a second redundant signal when the vehicle brake within the first predetermined time interval.
- the driver After the driver has been detected when the vehicle is at a standstill, it is maintained within a second predetermined time interval for carrying out a starting operation.
- the second time interval begins to run with the release of the brake.
- the predetermined minimum speed of the vehicle driver identification After exceeding the predetermined minimum speed of the vehicle driver identification is maintained as long as the minimum speed is not exceeded.
- it may additionally be provided to maintain the driver recognition when the minimum speed is undershot, as long as the time duration of the undershooting is less than a predetermined third time interval. This is chosen so short, for example, with a duration of 5 s, that falls below the mini- dest Bulgaria, especially when stopping, the driver may not have left the vehicle within this time interval.
- the driver operable emergency switch which has a redundant signal connection to the control device.
- a signal for driver detection is detected by the control device.
- the emergency switch is manually operated and arranged such that a mecanicdlich actuation or actuation by unattended playing in the vehicle children is avoided.
- the emergency switch can be arranged for example in the glove box of the vehicle.
- the safety of the driver recognition when using an emergency switch can be increased if it is combined with at least one of the measures mentioned in the preceding claims. For example, it is conceivable, after successful driver detection by pressing the emergency switch to maintain the driver detection to request the detection of another redundant signal when exceeding a minimum speed of the vehicle within a predetermined time interval.
- a redundant driver recognition for an emergency operation for example for driving in a workshop, initiated.
- Such redundant driver recognition is made possible by detecting redundantly transmitted signals for driver recognition via a redundant signal connection between the operating elements of the motor vehicle and the control device.
- a redundant signal direct connections such as a hard-wired signal connection, between selector lever and control device or between the vehicle brake and control device may be provided.
- a redundant driver recognition for a limp home is certainly possible on the basis of these signals by the clutch may only be closed when a change is detected on two redundant detected signals, for example, when the selector lever and the vehicle brake each change their position. After successful driver detection, this can be done for Carrying out an emergency run required closing the clutch using the still available for the controller signals or time-controlled.
- the selector lever from the neutral stage “N” or the parking stage “P” must be switched to a forward drive position “D (Drive)” or “M (Manual)” or to a reverse drive position “R” and within a predetermined first
- the operation of the selector lever and the vehicle brake and the detection of the corresponding redundant signals can also be performed in reverse order, ie the vehicle brake can be actuated first and then the selector lever
- the first time interval for example with a time duration of 2 s, is selected such that the probability that both signals due to a signal or hardware error or by accidental operation, for example by unattended playing children in the vehicle, Change very low or close to zero assumed
- the clutch can be closed within a second predetermined time interval beginning with the release of the vehicle brake, which corresponds to the usual time for a starting operation, for example 10 s.
- the driver detection is only maintained and the clutch is closed when another redundant signal is detected when a predetermined minimum speed of the vehicle is exceeded, otherwise the driver detection is canceled and the clutch is opened.
- the clutch remains closed as long as the minimum speed of the vehicle is exceeded.
- the minimum speed of the vehicle is chosen so that it is certain that the vehicle is in motion and the driver can not have left the vehicle.
