Abstract
A method is provided for monitoring and mitigating exhaust gas emitted from a vehicle in a closable structure. A remote monitoring device within the closable structure is trained in response to a training signal transmitted from a remote transmitter device. A remote engine start signal is intercepted within a receiving circuit of the remote monitoring device during an actual remote engine start operation. The exhaust gas emitted from the vehicle is monitored in response to receiving the remote engine start signal. A determination is made if an exhaust gas concentration level is greater than a predetermined threshold. A control signal is transmitted to a mitigation device for mitigating the exhaust gas within the closable structure when the exhaust gas concentration level is greater than the predetermined threshold.
