First Claim
Patent Images
1. A method for providing a bumper alert, the method comprises:
- generating or receiving information about a location of a vehicle;
generating or receiving information about a location of a bumper;
generating, by a computerized device, the bumper alert before the vehicle drives over the bumper;
wherein the computerized device is at least partially located within the vehicle when generating the bumper alert; and
wherein the generating of the bumper alert is based on a relationship between the location of the vehicle and the location of the bumper;
monitoring vibrations of the vehicle by a sensor; and
detecting, based on detection signals from the sensor, a passage of the vehicle over the bumper when finding three peaks in the detection signals that (a) are within a predefined distance from each other and (b) have a predefined peak to peak ratio;
wherein the detecting of the passage of the vehicle over each bumper of the one or more bumpers comprises at least one out of;
(i) comparing an absolute value of a detection signal to a sliding variance of a non-peak area; and
(ii) calculating a bumper detection reliability value indicative of a reliability of the detection of the passage of the vehicle over the bumper by using an average peak level of the three peaks.

15. A non-transitory computer readable medium that stores instructions for:
- generating or receiving information about a location of a vehicle;
generating or receiving information about a location of a bumper; generating, by a computerized device, the bumper alert before the vehicle drives over the bumper;
wherein the generating of the bumper alert is responsive to a relationship between the location of the vehicle and the location of the bumper; and
wherein the computerized device is at least partially located within the vehicle when generating the bumper alert;monitoring vibrations of the vehicle by a sensor; and detecting, based on detection signals from the sensor, a passage of the vehicle over the bumper when finding three peaks in the detection signals that (a) are within a predefined distance from each other and (b) have a predefined peak to peak ratio; wherein the detecting of the passage of the vehicle over each bumper of the one or more bumpers comprises at least one out of; (i) comparing an absolute value of a detection signal to a sliding variance of a non-peak area; and (ii) calculating a bumper detection reliability value indicative of a reliability of the detection of the passage of the vehicle over the bumper by using an average peak level of the three peaks. - View Dependent Claims (16, 17, 18, 19, 20)
