Abstract

The invention relates to a control device for a motor vehicle, which is connected via a data bus to at least one further electronic device, consisting of two computing units that exchange data with one another, the first computing unit controlling or regulating predetermined operating sequences of the motor vehicle, while the second computing unit is used for Monitoring the operation of the first computing unit is formed. DOLLAR A In a control unit that can be switched off immediately in the event of an error, the second arithmetic unit is connected to the first arithmetic unit and a first switch-off device via a signal line, the switch-off device being connected to an error signal from the second computer unit and a data signal from the first computing unit interrupts the access of the first computing unit to the data bus.

Description

The invention relates to a control device for a motor vehicle, which has a Da tenbus is connected to at least one other electronic device, be consisting of 2 computing units that exchange data with each other, whereby the first computing unit controls predetermined operating sequences of the motor vehicle and / or regulates while the second processing unit for monitoring the work as the first computing unit is formed.

Control devices for motor vehicles are known which have two computing units point (DE 41 14 999 A1). At least one computing unit records the operating process size of the motor vehicle and converts them into corresponding control signals for Actuators around. The second computing unit arranged in this control unit, assumes a monitoring function for the functioning of the first Re unit using a complicated software algorithm. When a Error, a signal is output to a shaft device, which emergency running measure took initiates.

A control device for a motor vehicle is known from DE 196 50 104 A1, which consists of two computers, each computer a main processor and has an associated subprocessor. Using a power circuit The operating state of the main processor is monitored, with one being off normal operating state of the main processor the power circuit a return transmits set signal that forcibly prevents the operation of the main processor det.  

Such control devices are used, for example, to control and regulate the combustion engine, as an ABS control unit to prevent the spinning of wheels used in the motor vehicle or as a distance control unit, the distance to detected a vehicle in front and either in the regulation of the speed intervenes or brakes the vehicle.

However, it is also possible for the second computing unit to also be partially used by the processor Most arithmetic unit evaluates recorded operating data and the result of the off reports back to the first processing unit.

If the second arithmetic unit now detects an error, the first arithmetic becomes unit due to a signal from the second arithmetic unit. Can the mistake the first arithmetic unit cannot be remedied by the reset, the first delivers Computing unit continues to send incorrect data to other control units via the data bus Councils of the motor vehicle are transmitted. Especially for control units Distance measurement or for distance control of the motor vehicle can do this critical effects in the driving situation of the motor vehicle up to accidents to lead.

From DE 41 07 330 C2 is also made up of two computing units Control device known. In the event of an error, the data exchange between them two processing units interrupted and the actuator switched off.

The invention is therefore based on the object of specifying a control unit which wel ches can be safely switched off in the event of an error.

According to the invention the task is characterized by the characteristics of the Pa claim 1 solved.

The advantage of the invention is that the first processing unit due to the Ab switching device can not send faulty data on the data bus.

When the error signal is output by the second processor, it is advantageous unit reset the first arithmetic unit as a result of this error signal. Can If the error is remedied by the reset, the control unit works in ge continued way. However, the reset of the first processing unit does not lead to  desired result, it is prevented by the first shutdown device that incorrect data is output.

In a further development of the invention, a final stage is the electronic device tion, via a second shutdown device with the first and the second Re Chen unit connected which, when the error signal of the second Computing unit and a release signal of the first computing unit, the output stage locks. With this arrangement, not only the data output to the Data bus prevented, but in addition a control of the Power amplifier prevents the steep signals for a connected actuator Influencing the driving behavior of the motor vehicle generated.

A particularly simple design allows the arrangement of the power amplifier electronic device in the control unit itself.

To ensure the functionality of the processor monitoring and shutdown path check To ensure, it is checked when starting the motor vehicle whether the second Processing unit the data bus deactivation and locking the power amplifier electronic device.

Advantageously, the second arithmetic unit is not only for monitoring the Functionality of the first arithmetic unit trained, but leads itself through individual functions of the motor vehicle.

In particular, if the first computing unit for the distance control of the Motor vehicle is designed to a preceding vehicle, the second arithmetic unit has a distance sensor which emits signals that be reflected by the preceding object, the second being evaluates the reflected signals received by the distance sensor and transmits the evaluated data to the first computing unit, which in  Depending on this evaluated data, the final stage of the electronic Control device.

The invention permits numerous embodiments. One of them should be based on the figures shown in the drawing are explained in more detail.

It shows:

Fig. 1: Arrangement of the distance control device in a motor vehicle

Fig. 2: basic structure of the distance control device.

Identical features are identified by the same reference symbols.

In Fig. 1, an automatic distance and speed control system 3 is arranged on the bumper 2 of a motor vehicle 1 to maintain the safety stand of vehicles. The automatic distance and speed control system 3 is connected, for example, to the control unit of the engine control unit 5 , the control unit of the brake 7 and the control unit of the transmission 8 via a bus system 4 present in the vehicle 1 . Electronic commands, which are exchanged via the bus system 4 , regulate the speed to the vehicle in front until the desired distance is reached.

Via a display unit 6 , which is also controlled by the speed and distance control system 3 via the bus system 4 , the current speed and the distance to the vehicle in front is shown. The vehicle in front is detected by the sensor beam 9 , which is emitted by a radar sensor 10 which is part of the speed and distance control device 3 .

As shown in FIG. 2, the automatic distance and speed control system 3 forms a structural unit between sensor 10 , sensor signal processing arrangement 11 and distance control system 12 . The sensor signal processing arrangements 11 are designed as a second computing unit and the distance control system 12 as a first computing unit.

The distance control system 12 has a device for determining a future lane of the vehicle and an object lane of the comparison object as well as a longitudinal controller which determines the actual distance to a control object, compares it with a predetermined stored target distance and, if there is a deviation due to interventions in the engine control 5 or the brake 7 or the transmission 8 establishes the target distance to the control object.

The sensor 10 sends signals at regular intervals, for example every sixty milliseconds, in the direction of travel of the vehicle 1 , which signals are reflected by the vehicles located in the sensor beam 9 . From these reflected signals, the distance, the relative speed and the acceleration of the preceding vehicles are determined by the computing unit 11 . These measurement results are passed on from the computing unit 11 to the computing unit 12 via the data line 13 .

In addition, the computing unit 11 is connected to the computing unit 12 via the signal lines 14 and 15 . By means of a software algorithm stored in it, the computing unit 11 monitors the operation of the distance control device 12 . If the computing unit 11 detects an error, the "fail-save" line 15 is activated. The microcomputer of the computing unit 12 is reset by this. The "fail-save" line 15 is also connected to the logic unit 16 , which is also connected to the data output output T × D of the computing unit 12 . The output of the logic unit 16 is connected to the data bus 4 .

The signal line 14 is used to release an output stage 18 , which is also arranged in the speed and distance control device 3 and which is used to control an actuator 19 , for example a brake. Between the signal line 14 and the output stage 18 , a second logic unit 17 is arranged, the second input of which is connected to a release output FE of the computing unit 12 for output stage release by the computing unit 12 .

If the computing unit 11 , which is used to monitor the computing unit 12 , detects an error, it delivers a signal to the logic unit 16 via the line 15 . At the same time, a reset of the computing unit 12 is triggered by this signal. If this reset is unsuccessful and a data signal is still present at data output T × D, logic unit 16 interrupts the connection to data bus 4 . This logic unit 16 is an AND gate, which switches only when two input signals are present.

In addition to checking the microprocessor, the computing unit 11 sends an output stage enable signal via the line 14 . In the event of an error, this output stage enable signal is not sent. If the enable signal also remains from the computing unit 12 , the output stage control of the output stage 18 is interrupted for the entire driving cycle. The logic unit 17 is designed equivalent to the logic unit 16 .

In order to determine whether the computing unit 11 also correctly carries out the CanBus deactivation by locking the output stage, a check is preferably carried out once when the control unit is started during the initialization phase of the two computing units to determine whether this capability is present.

With this simple device, a safe disconnection of the distance and speed control system 3 from other systems of the motor vehicle is ensured, which are then fully functional even without a distance control device.
