Definitions

  • the invention relates to a device for controlling a motor vehicle generator
  • the output voltage of a generator depends on several influencing factors, which include the speed, the electrical load in the vehicle electrical system, the state of charge of the starter battery and the temperature.
  • the generator controller regulates the output voltage of the generator within predefined limits. This regulation takes place via an adaptation of the exciter current flowing through the field winding of the generator. To adjust the excitation current, a change of the duty cycle of a PWM drive signal is performed.
  • a proposed for a motor vehicle electrical system power supply which has a battery, a generator and a controller.
  • the generator is used to charge the battery.
  • the controller is intended to control the generator voltage.
  • the regulator includes a controller, a controlled by the controller first switch for controlling the generator voltage in normal operation and a controllable by the controller second switch for controlling the generator voltage in case of malfunction of the first switch.
  • the first switch is arranged between a supply voltage connection terminal and a connection of the exciter winding of the generator.
  • the second switch is provided between the other terminal of the field winding and ground.
  • the controller has its own ground connection. Due to the redundant design of the controller, its reliability is increased.
  • a device for controlling a motor vehicle generator with the features specified in claim 1 has the advantage that in the case of any interruption of the supply of the regulator control of the generator regulator, in particular an ASIC of the generator regulator, and the exciter circuit is interrupted. This prevents the occurrence of overvoltages in the electrical system. Such overvoltages in the vehicle electrical system could lead to vehicle electrical system states with serious effects, for example a shutdown or overloading up to a failure of components that are required for the driving of the motor vehicle.
  • This advantage is essentially achieved in that the excitation winding is applied to the regulator controller in both poles and is preferably connected in both poles to the ASIC of the generator regulator.
  • FIG. 1 shows a block diagram of a first device for controlling a motor vehicle generator.
  • FIG. 2 shows a block diagram of a second device for controlling a motor vehicle generator.
  • the device shown in FIG. 1 has a generator controller 1, a generator unit 28 with a generator 2 and a rectifier arrangement 11, a battery 12, loads 13, an inductive load 14, the terminal 15 and a control unit 16.
  • the generator regulator 1 contains a regulator controller 7a implemented as an integrated circuit and customer-specific connections such as the connection LIN shown in FIG. 1 and connections B +, DF +, DF- and X to the generator 2.
  • the connection LIN is connected via a capacitor 18 Mass connected.
  • the task of the capacitor 18 is to filter the signals provided at the LIN terminal.
  • the integrated circuit 7a has a non-illustrated control unit, an ohmic resistor 20, a switching transistor 21, a diode 23 and a switching transistor 6a.
  • the integrated circuit 7a has connections 8, 9, 24, 25 and 26 as well as a detection input 10.
  • the terminal 8 of the integrated circuit 7a is connected via the terminal DF of the generator regulator 1 to the second terminal 5b of the exciter winding 5 of the generator 2.
  • the terminal 9 of the integrated circuit is connected via a ground connection 3 to ground 4.

  • the detection input 10 of the integrated circuit 7a is connected via the terminal X of the generator controller 1 with the phase voltage terminal W of the generator in connection PHg.
  • the connection 26 of the integrated circuit 7a is connected to the external control unit 16 via the connection LIN of the generator controller 1.
  • Switching transistor 6a connected such that the first terminal 5a of the field winding 5 is connected via the switching transistor 6a of the integrated circuit to the operating voltage connection B +.
  • the terminal 24 of the integrated circuit 7a is connected via the generator unit 28, to which the generator 2 and the rectifier arrangement 11 belong, to the vehicle electrical system BN of the motor vehicle.
  • the generator 2 has, in addition to the already mentioned excitation winding 5 not shown phase windings, which are connected to phase voltage terminals U, V, W of the generator 2.
  • the phase voltages generated at the phase voltage connections are rectified by the rectifier arrangement 11 and then forwarded to the on-board network BN.
  • the rectifier arrangement 11 has a ground connection IIa via which it is connected to ground 4.
  • the battery 12 To the electrical system BN, the battery 12, the consumer 13, the inductive load 14 and the terminal 15 are connected.
  • the controller controller 7a loses its intended reference potential. It turns via the regulator controller 7a a random voltage, whose height depends on the external circuit of the integrated circuit and parasitic connections. Typically, this random voltage is less than the actual voltage at the generator regulator terminals. For this reason, the control unit of the integrated circuit 7a tries to increase the voltages at the terminals of the integrated circuit. The control unit of the integrated circuit 7a can not recognize that an error has occurred.
  • the second connection is in the present invention 5b of the field winding 5 via the terminal DF and the terminals 8 and 9 of the integrated circuit 7a and the ground connection 3 of the integrated circuit 7a connected to ground 4.

  • the integrated circuit 7b differs from the integrated circuit 7a shown in FIG. 1 in that the terminals 24 and 25 of the integrated circuit 7b are directly connected to each other within this integrated circuit via a line and the switching transistor 6b is connected between the terminal 8 and the Terminal 9 of the integrated circuit is provided within this integrated circuit 7b. Consequently, in this embodiment, the first terminal 5a of the field winding 5 is connected directly to the operating voltage terminal B + via the integrated circuit 7b, while the second terminal 5b of the field winding 5 is connected via the switching transistor 6b to the terminal 9 and via this and the ground connection 3 of the integrated circuit 7b is connected to ground 4.
  • the exciter circuit of the generator is also interrupted so that no undesired overvoltages occur in the vehicle electrical system.
  • both terminals of the field winding are connected to the controller control of the generator controller or its ASIC and are thus integrated into the supply path of the controller control.
