Control system, particularly for a motor vehicle
First Claim
1. A control system, suitable for a motor vehicle, the system comprising a timer circuit, and at least one control unit which, for the production of control parameters, is connected with the timer circuit for the production of a time parameter, wherein the timer circuit is located outside of the control unit for the purpose of determining an engine shutdown time;
- the control unit is a first control unit, the system further comprising a second control unit, and the timer circuit is located in the second control unit;
wherein the second control unit is the control electronics of an instrument cluster of a motor vehicle.

Abstract
A control system, particularly for a motor vehicle, having at least one control device which, in order to produce control parameters, is connected with a timer circuit for the production of a time parameter. In order to provide a control system in which a timer signal is available at all times, without the voltage supply system of the motor vehicle being under load when the engine is turned off, the timer circuit is located outside the control device.

8. A method for determining a control parameter for a motor vehicle with the aid of a time parameter by means of a control system suitable for a motor vehicle, the system comprising a timer circuit, and at least one control unit which, for the production of control parameters, is connected with the timer circuit for the production of a time parameter, wherein the control unit is a first control unit, the system further comprising a second control unit;
the method comprising steps of; locating the timer circuit outside of the control unit for the purpose of determining an engine shutdown time; determining, with the aid of an additional signal, a time at which the time parameter is transferred or stored; and employing a control electronics of an instrument cluster of a motor vehicle as the second control unit. - View Dependent Claims (9, 10, 11, 12)
