| 发明名称 | Detecting vehicle door ajar using intrusion sensor | ||
| 摘要 | A vehicle includes an intrusion sensor configured to detect a Doppler shift in a passenger compartment and output an intrusion signal representing the Doppler shift. The vehicle further includes a processing device configured to receive the intrusion signal and activate an alarm if the Doppler shift exceeds a predetermined threshold. A method includes measuring a Doppler shift in a passenger compartment of a vehicle, comparing the Doppler shift to a predetermined threshold, and activating an alarm system if the Doppler shift exceeds the predetermined threshold. | ||

| 主权项 | 1. A vehicle system comprising: an intrusion sensor configured to detect a Doppler shift in a passenger compartment and output an intrusion signal representing the Doppler shift; a processing device programmed to deactivate a door ajar sensor during a key-off cycle, receive the intrusion signal, and activate the door ajar sensor during the key-off cycle if the Doppler shift exceeds a predetermined threshold when an alarm system is armed. | ||
