Drive-away blocking device

A vehicle security system with an anti-theft controller which conducts a data exchange with at least one function controller, particularly an engine controller, in order to control its operational readiness, wherein the data exchange is conducted via a data line connecting at least the anti-theft controller and the function controller. Alternatively, an external device (4) can be connected to the data line (1), with the device being configured for the exchange of data with at least one of the controllers (2, 3, 3', 3') The data line is a line which is already in existence in the vehicle, particularly a K-diagnostics line and/or an L-diagnostics line in accordance with ISO standard 9141. For the control of the data exchange, one of the controllers (2, 3) connected via the data line (1) exercises the functions of the control unit. If an external device (4) is connected to the data line (1, 1'), the external device assumes the function of the control unit from the controller (2, 3) controlling the data exchange in order to conduct the data exchange with the controllers (2, 3, 3', 3') connected via the data line (1).

The invention relates to a microprocessor circuit arrangement having a watchdog circuit, which monitors the proper program flow for the processor and which must be triggered in specific time intervals by the microprocessor, since otherwise it will reset (reset function) the microprocessor to the program start or the like. For reasons of simplification, it is proposed that when the microprocessor (2) recognizes that a malfunction has occurred, it spuriously triggers the watchdog circuit (5) in a selective manner to release a reset function coming from the watchdog circuit (5).

In a method for controlling the release of a passenger restraint system in a vehicle, an acceleration signal is measured and integrated with respect to time to obtain a velocity signal. A release threshold value for the velocity signal is determined. If the velocity signal then falls below the release threshold value, thus indicating a vehicle collision, the passenger restraint system is released. The release threshold value is controlled depending on the type of accident situation and upon the operating parameters of the vehicle to increase the release sensitivity of the passenger restraint system. For example, the release threshold value is adjusted based on the value of the velocity signal. If the velocity signal decreases in value, then the release threshold is lowered to a more sensitive value.
