Abstract
A security system for a motor vehicle is described. The security system has at least one sensor for sensing a status variable of the motor vehicle, a security device for disabling or enabling use of the motor vehicle, and a control unit, connected at the input end to the sensor and at the output end to the security device. The control unit disables activation of the security device as a function of the status variable, in order to prevent incorrect operation. The control unit has a logic circuit that not only blocks the security device preventing activation, as a function of the status variable, but also activates the security device as a function of the status variable, independently of a user intervention.
