Abstract
A vehicle proximity sensor system comprising: a magnetometer; and a controller configured to: receive a reference magnetic field signal from the magnetometer; receive a measurement magnetic field signal from the magnetometer; determine magnetic field displacement data based on the measurement magnetic field signal and the reference magnetic field signal; and signal the presence of a vehicle based on the magnetic field displacement data.
Claims20
A vehicle proximity sensor system comprising:
- a safety structure susceptible to vehicle collisions and comprising a magnetometer;
- an alert signal generator;
- and
- a controller configured to:
- receive a reference magnetic field signal from the magnetometer;
- receive a measurement magnetic field signal from the magnetometer;
- determine magnetic field displacement data based on the measurement magnetic field signal and the reference magnetic field signal;
- and
- signal a presence of a vehicle based on the magnetic field displacement data,
- wherein the controller is configured to signal the presence of the vehicle by activating the alert signal generator, the alert signal generator configured to alert a driver of the vehicle to a proximity of the vehicle to the safety structure.
