Definitions
- the invention relates to a method for braking a vehicle, wherein the vehicle has a gearbox controlled by a transmission control unit and a drive train of a vehicle.
- DE 10 2009 021 894 B1 discloses a method for controlling a drive train of a motor vehicle, in which, in the event of a defect in the transmission, braking is effected by means of an automatically actuated brake system.
- the brake used for this is designed as a transmission brake.
- the invention has for its object to provide a method for braking a vehicle and a drive train of a vehicle, in which by means of structurally simple methods, a reliable braking of the vehicle in case of a defect in the transmission is possible.
- the object is achieved in that the transmission control unit requests a brake intervention. Since the transmission control unit usually also detects the defect in the control unit, it can immediately request a braking maneuver to exclude a hazardous situation in the vehicle.
- the brake control electronically requested by the transmission control unit is implemented by a vehicle brake. It can be dispensed with a transmission brake, as this can be transmitted very quickly to the vehicle brake by the electronic requirement of the brake intervention.
- the transmission control unit requests the braking intervention from a brake control unit, which converts the request into a torque of at least one wheel brake designed as a vehicle brake. It is sufficient if the transmission control unit carries out an electronic communication with the brake control unit. This simplifies the structural arrangement between the transmission control unit and the brake control unit.
- the transmission control unit and the brake control unit communicate via a bus system of the vehicle. Due to the use of the bus system, the transmission control unit and the brake control unit can communicate with one another quickly by means of command data records.
- a development of the invention relates to a drive train of a vehicle in which an engine via a transmission drives wheels of the vehicle, wherein the transmission is controlled by a transmission control unit and the vehicle has a controlled by a brake control device vehicle brake for braking the vehicle.
- the transmission control device for the electronic request of a brake intervention is connected directly to the brake control device for actuating the vehicle brake.
- the transmission is designed as a hybrid transmission structure. Since such hybrid transmission structures, which can be driven both by an internal combustion engine and by an electric motor, are very complicated, it is of particular advantage here if integration of a transmission brake into such a hybrid transmission structure can be dispensed with.
- the transmission control unit and the brake control unit are connected to one another via a data line. This eliminates a constructive coupling between the transmission and brake, since only an electronic communication between Gereteriosesteu- er réelle and brake control unit is necessary.
- the brake control unit is designed as an ABS control unit or ESP control unit or ASR control unit. Thus, as a brake control unit different in the vehicle itself existing control devices that include a braking function can be used. On a separate brake control unit can thus be dispensed with, which reduces the manufacturing cost of the vehicle.
- Fig. 1 shows an embodiment of a drive train according to the invention of a vehicle.
- 1 shows an exemplary embodiment of a drive train 1 according to the invention of a vehicle, in which a transmission 2 is controlled by a transmission control unit 3.
- the transmission 2 is connected via a differential 4 with vehicle wheels 5.
- Via a data bus 6, for example a CAN bus, the transmission control unit 3 is connected to a brake control unit 7, for example an ABS control unit.
- the brake control unit 7 of a brake actuator not shown is coupled via corresponding hydraulic lines 8, each with a vehicle wheel 5 opposite wheel brakes 9.
- the transmission control unit 3 electronically requests a brake intervention from the brake control unit 7 in order to be able to undertake a controlling intervention in the transmission 2.
- the brake control unit 7 converts the request of the transmission control unit 3 into a moment, which is set on the wheel brakes 9, whereby the vehicle wheels 5 are braked by the wheel brakes 9.
- the transmission control unit 3 Before the request of the braking intervention by the transmission control unit 3 is output to the brake control unit 7, the transmission control unit 3 checks whether the vehicle is in a driving situation, where the braking intervention provides a reliable and accident-free deceleration. sen of the vehicle guaranteed. If this test leads to the result that a braking operation causes an unsafe driving situation of the vehicle, the request for the braking intervention is not output to the brake control device 7. However, the request of a brake intervention by the transmission control unit 3 can also take place in a fault-free operation of the transmission 2. This is the case, for example, in the case of a transmission 2, which includes a claw which becomes torque-free when the output is torque-free. Such a claw can only be opened if it is torque-free.
- the vehicle shown in Fig. 1 drive train 1 comprises a front transverse transmission.
- the invention is not limited to such a transmission, but can be applied to all types of drive such as standard drive, all-wheel drive and the like.
