Automotive authorization control

A two-sided system for triggering a selected functionality of a piece of operable equipment when monitoring a mutual recognition zone of said two sides, initially detecting a target tag in said mutual recognition zone and subsequently detecting a target human, and recognizing at a first side of the two-sided system a known triggering pattern for said selected functionality performed by said target human, comprising:

• said first side of the system having an electronic control unit (ECU) mountable to said piece of operable equipment, and the first side of the system further having a memory with a record of said known triggering pattern and said selected functionality;
• said target tag comprising a mobile tag in said second side of the system, capable of exchanging communication with said ECU when within said mutual recognition zone;
• said two-sided system being functional to detect the target tag when within the mutual recognition zone and to make an approximate initial determination of distance between the target tag and the piece of operable equipment based upon exchanged communication between the target tag and the ECU;
• the two-sided system further comprises an accelerometer configured to monitor the target tag and to perform inertial navigation thereof, wherein the ECU controls the inertial navigation to be activated after the system has detected the target tag within the mutual recognition zone, the accelerometer employing inertial navigation to determine inertial navigation data and to communicate said inertial navigation data to the ECU, enabling determination of at least position, orientation, and velocity of the target tag in the mutual recognition zone,
• the first side of the system further comprises a radar module having a sensor transmitting a radar scan into a radar field proximate to the piece of operable equipment and a sensor receiving back a reflection of said radar scan, the scan using a frequency suitable to detect a human target or portion thereof and a stationary object, if any, and suitable to reflect back therefrom, whereby said human target or portions thereof and stationary object are detected without necessity of combined location with the target tag;
• wherein the radar module generates radar data indicative of distance to the detected human target or portion thereof and stationary object, and the radar module communicates the radar data to the ECU;
• the ECU having a receiver for receiving said inertial navigation data and radar data, the ECU further having an ECU processor communicating with said memory to determine when the inertia navigation data and radar data shows that the monitored human target has performed the known triggering pattern, and in response thereto the ECU issuing a triggering signal;
• and
• wherein said first side of the two-sided system is connectable to said piece of operable equipment such that the triggering signal triggers the selected functionality.
