Abstract
An intrusion detection system for a vehicle includes a radar sensor, a calculator, and an alarm system adapted to generate an alarm, the radar sensor being adapted to detect the presence of a body within the vehicle, the calculator being adapted to categorize each detected body as either a “human” category or an “other” category and to trigger the alarm system only when at least one of the detected body(ies) is categorized as “human”. Also included is an associated vehicle and method.
Claims11
An intrusion detection system for a vehicle comprising a radar sensor, a calculator and an alarm system adapted to generate an alarm, the radar sensor being adapted to detect the presence of at least one body within the vehicle, the calculator being adapted to categorize each detected body between a “human” category and an “other” category and to trigger the alarm system only when at least one of the at least one detected body is categorized as “human”,
- wherein the radar sensor is adapted to detect a body mass of each of the at least one detected body,
- the radar sensor being adapted to map surroundings of the radar sensor in a heatmap based on reflected waves, corresponding to radio waves generated by the radar sensor and reflected by the at least one body surrounding said radar sensor, the abscissa and ordinate of each point of the heatmap corresponding to a position of said point in relation to the radar sensor, a value of said point in the heatmap showing at least one parameter of the corresponding reflected waves, and
- the calculator being adapted to categorize each detected body of the at last one detected body between the “human” category or the “other” category based on the shape of mass of the detected body on the heatmap.
A method for detecting intrusion into a vehicle, comprising the following steps:
- providing an intrusion detection system including a radar sensor, a calculator and an alarm system adapted to generate an alarm,
- detecting the presence of at least one body in the vehicle, the radar sensor being adapted to map surroundings of the radar sensor in a heatmap based on reflected waves, corresponding to radio waves generated by the radar sensor and reflected by the at least one body surrounding said radar sensor, the abscissa and ordinate of each point of the heatmap corresponding to a position of said point in relation to the radar sensor, a value of said point in the heatmap showing at least one parameter of the corresponding reflected waves, the radar sensor being adapted to detect a body mass of each detected body of the at least one body, the calculator categorizing each detected body as either a “human” or “other” category,
- the calculator being adapted to categorize each detected body of the at least one detected body between the “human” category or the “other” category based on the shape of mass of the detected body on the heatmap, and
- generating an alarm by the alarm system only when at least one of the at least one detected body is categorized as “human”.
