Abstract

A method for monitoring a vehicle, the method may include measuring a speed of the vehicle to provide speed measurements; measuring, by at least one vibration sensor, vibrations of the vehicle to provide vibrations measurements; determining, based on the vibration measurements and speed measurements, an actual relationship between speed and vibrations of the vehicle; comparing between the actual relationship between the speed and vibrations of the vehicle and a reference relationship between speed and vibrations of the vehicle to provide a comparison result; and determining the quality of the driving based on the comparison result.

Claims

1. A method for monitoring a vehicle, the method comprising:

measuring, by a speed sensor that is installed in the vehicle and while the vehicle is driven by a driver, a speed of the vehicle to provide speed measurements;

measuring, by multiple vibration sensors that are installed in the vehicle and while the vehicle is driven by the driver, vibrations of the vehicle to provide vibrations measurements;

determining, by a computer that is installed in the vehicle, based on the vibration measurements and speed measurements, an actual relationship between speed and vibrations of the vehicle;

comparing, by the computer, between the actual relationship between the speed and vibrations of the vehicle and a reference relationship between speed and vibrations of the vehicle to provide a comparison result;

determining, by the computer, a quality of the driving of the vehicle by the driver, based on the comparison result; and

increasing the rate of the vibration measurements when sensing that the vehicle is about to cross an obstacle.

2. The method according to claim 1 comprising sensing that the vehicle is about to cross the obstacle by another sensor that differs from an accelerometer.

3. A method for monitoring a vehicle, the method comprising:

measuring, by a speed sensor that is installed in the vehicle and while the vehicle is driven by a driver, a speed of the vehicle to provide speed measurements;

measuring, by multiple vibration sensors that are installed in the vehicle and while the vehicle is driven by the driver, vibrations of the vehicle to provide vibrations measurements;

determining, by a computer that is installed in the vehicle, based on the vibration measurements and speed measurements, an actual relationship between speed and vibrations of the vehicle;

comparing, by the computer, between the actual relationship between the speed and vibrations of the vehicle and a reference relationship between speed and vibrations of the vehicle to provide a comparison result;

determining, by the computer, a quality of the driving of the vehicle by the driver, based on the comparison result; and

increasing a rate of the vibration measurements when sensing that the vehicle crosses an obstacle.
