Definitions

  • the invention relates to a method for starting the engine of a vehicle according to the preamble of claim 1.
  • the Rolling resistance when switching off the engine often the first gear automatically inserted This state must be canceled when starting the vehicle be otherwise an unintentional movement of the vehicle would be done.
  • the driver must first make sure that the neutral setting selected or the drive train is interrupted. Is not this the case, he must first select the neutral position or the drive train to interrupt. If he does not carry out this step, he can Engine cannot be started for safety reasons. He takes this step however, he often has to use the service brake to start the engine press to secure the vehicle against rolling away.
  • DE 196 32 863 A1 describes a motor vehicle with a parking brake known in which, depending on the vehicle operating state, a hydraulic or electro-mechanical operating mode can be selected.
  • a hydraulic or electro-mechanical operating mode can be selected.
  • the vehicle brake is used when using the vehicle hydraulic mode and after leaving by means of the electromechanical Mode operated.
  • a decision to switch can be made based on a door control, a driver seat occupancy detection or one Ignition activation is recognized. An automatic actuation of a however, the brake not previously operated is not described.
  • DE 196 29 426 A1 is an automated parking brake described in which the parking brake at the end of driving is actuated automatically. On the other hand, when driving starts the parking brake released again.
  • the object of the present invention is to provide a simple method for increasing driving safety and ease of use when starting an engine specify.
  • An essential essence of the invention is that an upcoming tempering of the engine is recognized. This is followed by starting the engine the vehicle brake released at first for securely locking the vehicle actuated via external force.
  • the upcoming starting of the vehicle can be done, for example, via the Unlocking the vehicle, opening the vehicle door, driver seat occupancy detection and / or an actuation of the ignition lock or the Ignition / starter determination can be determined.
  • the actuation of a Starter or ignition device is particularly closely connected to one impending engine start.
  • the Invention first check whether the gear selector is neutral is posed. If this is not the case, the gear selection device can be used starting the engine to neutral or the drivetrain be decoupled. For example, when turning the ignition key to the "ignition on” position the vehicle brake is applied and the clutch be opened. This is special for a vehicle with one automated manual transmission is an advantage, as an additional safety function first gear is engaged when the engine is switched off.
  • Solving the Vehicle braking may be in response to the actuation of a pedal, for example an accelerator pedal or a brake pedal.
  • the vehicle brake is actuated - as in the preamble of the claim 1 specified - about external power; d. H. the one for the vehicle brake brake pressure to be applied or the braking energy - depending on whether electrically, pneumatically or hydraulically operated - must have a corresponding Secondary device are generated in the vehicle.
  • a preferred embodiment of the invention is therefore characterized in that that the vehicle brake is released again after a certain time after activating the vehicle brake no engine start is done.
  • a parking brake can also be applied with respect to the parking brake that only requires energy itself, the parking brake after actuation, however, like the conventional handbrake is kept in a locked state.
  • the present invention is an inexpensive, simple, Safety and comfort increasing procedure for starting the engine of a vehicle.
  • the ease of use is an inexpensive, simple, Safety and comfort increasing procedure for starting the engine of a vehicle.
  • Vehicle start increases without the driver taking additional actions before Must start the vehicle. Moreover, safety is through avoidance incorrect operation and rolling away of the vehicle when starting of the vehicle.
  • a vehicle brake is a prerequisite for performing the procedure, which can be operated via external force.
  • Such vehicle brakes are in the Most of today's vehicles are in the form of brake control systems.
  • Sufficient hydraulic pressure is usually provided by a separate pump provided for a hydraulic brake circuit and this hydraulic pressure according to the braking requirements via valves modulated.
  • any other can also be operated via external power Vehicle brake, for example a purely electric brake become.
  • a remote control signal be evaluated to unlock or release the vehicle door. It is also possible to evaluate the door opening switch.
  • the present procedure checks whether the ignition key is in the start position ("Ignition On" position) was turned. If this is the case, then a Corresponding signal passed on to a control unit, which on a imminent engine start closes (step 10).
  • the service brake is then automatically activated in step 12.
  • the present method is used in a vehicle with automated Manual transmission used, the first when parking the vehicle Gear is engaged. For this reason, in step 12 after the automatic Activating the service brake automatically opens the clutch. Alternatively, the neutral gear could also be engaged.
  • step 16 the internal combustion engine is started in step 16, which is due to the previous measures cannot lead to immediate movement of the vehicle.
  • the service brake is in step 18 solved when any pedal of the vehicle, for example that Accelerator pedal or the brake pedal is operated. By pressing one These pedals signal the driver that he is in a ready to drive state and is in control of the vehicle.
