Alcohol interlock system with wireless data transmission and safety function
First Claim
1. An interlock system for a vehicle, the interlock system comprising:
- an alcohol tester for measuring an alcohol level of a driver of the vehicle;
a control device coupled with said alcohol tester for allowing starting of the vehicle or preventing the vehicle from being started depending on the measured alcohol level; and
a transceiver module coupled with said control device for sending data to a remotely located control system in a wireless manner and for receiving data in a wireless manner, said transceiver module releasing said control device in response to data received in a wireless manner in order to allow starting of the vehicle regardless of an operating state of said control device, said control device having a switching device coupled with a starter of the vehicle, said switching device being switched by means of an analyzing unit of said control device depending on the measured alcohol level, said transceiver module having a transceiver module switching device connected in parallel to said switching device of said control device, said transceiver module switching device being switched in response to data received in a wireless manner.

Abstract
An interlock system (1) for a vehicle is provided with an alcohol tester (4), which is designed to measure the alcohol level of a driver of the vehicle. A control device (2) is coupled with the alcohol tester (4) and is designed to make it possible to start the vehicle or to prevent the vehicle from being started depending on the measured alcohol level. A transceiver module (3) is coupled with the control device (2) and is designed to send data to a remotely located control system in a wireless manner or to receive data from said control system in a wireless manner. The transceiver module (3) is designed, furthermore, to release the control device (2) in response to data received in a wireless manner in order to make it possible to start the vehicle regardless of the operating state of the control device.
