Determination of a motorcycle rider's experience level
Force-detecting sensors are installed in a motorcycle's handlebars, footpegs and seat to detect the rider's grip, weight and weight distribution. A control unit interprets the signals from the sensors to determine an attribute of the rider or an intention of the rider to make a manoeuvre. Signals from environmental sensors are used by the control unit to determine whether the intended manoeuvre would endanger the rider, and, if so, the rider is alerted before the manoeuvre is undertaken. The alert is provided before the rider notices the hazard, or before the rider reacts to the hazard. By giving advance warning, of as little as a fraction of a second, a rider is given extra time to avert a potential accident. The control unit also controls settings of the motorcycle during a hazardous state of the motorcycle.
1. A system for determining a motorcycle rider's experience level comprising:
a plurality of force sensors located in a seat of the motorcycle so as to detect forces exerted on the seat by the rider of the motorcycle;
a turn sensor that detects whether the motorcycle is turning; and
a control unit communicatively connected to the force sensors and turn sensor and configured to:
receive a signal from the turn sensor;
determine, based on the signal from the turn sensor, that the motorcycle is making a turn;
receive signals from the force sensors while the motorcycle is making the turn;
determine, based on the signals from the force sensors, a position of the rider on the seat; and
register the experience level of the rider, wherein the experience level depends on the position of the rider.
2. The system of claim 1 , wherein the position of the rider is neutral, leaning on a side of the seat that is the same as a direction of the turn, or leaning on a side of the seat that is opposite to the direction of the turn.
3. The system of claim 2 , wherein the experience level of the rider is registered as:
experienced if the rider is determined to be sitting in the neutral position;
advanced if the rider is determined to be leaning on the same side of the seat as the turn; or
novice if the rider is determined to be leaning on the opposite side of the seat to the turn.
4. The system of claim 1 , wherein the turn sensor is in a handlebar of the motorcycle.
5. The system of claim 1 , wherein the turn sensor is an accelerometer.
6. The system of claim 1 , wherein the turn sensor is a handlebar rotation sensor.
7. The system of claim 1 , wherein the plurality of force sensors is nine.
8. The system of claim 1 , further comprising an environmental sensor mounted on the motorcycle and connected to the control unit, wherein the control unit is configured to:
receive signals from the environmental sensor; and
determine, based on the signals from the environmental sensor, whether there is a hazard for the rider.
9. The system of claim 8 , further comprising an output device communicatively connected to the control unit, wherein the control unit is configured to activate the output device when the control unit determines that there is a hazard for the rider.
10. The system of claim 9 , wherein the output device is activated differently depending on the registered experience level of the rider.
11. The system of claim 9 , wherein the output device is one or more of:
a haptic device embedded in a seat, handlebar or footpeg of the motorcycle;
a light-emitting diode; and
an audible device.
12. The system of claim 1 , wherein:
the control unit is communicatively connected to an engine control unit (ECU) of the motorcycle; and
the control unit is configured to:
read parameters of the motorcycle from the ECU;
determine a hazardous state of the motorcycle from values of the parameters and from the registered experience level of the rider; and
send an alternate value of at least one of the parameters to the ECU to control at least one setting of the motorcycle during the hazardous state.
13. The system of claim 12 , wherein the hazardous state is harsh braking and the alternate value is a suspension setting.
14. A method for determining a motorcycle rider's state comprising:
locating a plurality of force sensors in a seat of the motorcycle so as to detect forces exerted on the seat by the rider of the motorcycle;
installing in the motorcycle, a turn sensor that detects whether the motorcycle is turning;
receiving, by a control unit, a signal from the turn sensor;
determining, by the control unit, based on the signal from the turn sensor, that the motorcycle is making a turn;
receiving, by the control unit, signals from the force sensors while the motorcycle is making the turn;
determining, by the control unit, based on the signals from the force sensors, a position of the rider on the seat; and
registering, by the control unit, the experience level of the rider, wherein the experience level depends on the position of the rider.
15. The method of claim 14 , wherein the position of the rider is determined to be neutral, leaning on a side of the seat that is the same as a direction of the turn, or leaning on a side of the seat that is opposite to the direction of the turn.
16. The method of claim 15 , wherein the experience level of the rider is registered as:
experienced if the rider is determined to be sitting in the neutral position;
advanced if the rider is determined to be leaning on the same side of the seat as the turn; or
novice if the rider is determined to be leaning on the opposite side of the seat to the turn.
17. The method of claim 14 , wherein the turn sensor is installed in a handlebar of the motorcycle.
18. The method of claim 14 , wherein the turn sensor is an accelerometer.
19. The method of claim 14 , wherein the turn sensor is a handlebar rotation sensor.
20. The method of claim 14 , wherein the plurality of force sensors is nine.
21. The method of claim 14 , further comprising:
mounting an environmental sensor on the motorcycle;
receiving, by the control unit, signals from the environmental sensor; and
determining, by the control unit, based on the signals from the environmental sensor, whether there is a hazard for the rider.
22. The method of claim 21 , further comprising:
activating an output device in response to determining that there is a hazard for the rider.
23. The method of claim 22 , wherein the output device is activated differently depending on the registered experience level of the rider.
24. The method of claim 22 , wherein the output device is one or more of:
a haptic device embedded in a seat, handlebar or footpeg of the motorcycle;
a light-emitting diode; and
an audible device.
25. The method of claim 14 , further comprising:
reading, by the control unit, parameters of the motorcycle from an engine control unit (ECU);
determining, by the control unit, a hazardous state of the motorcycle from values of the parameters and from the experience level of the rider; and
sending, by the control unit, an alternate value of at least one of the parameters to the ECU to control at least one setting of the motorcycle during the hazardous state.
26. The method of claim 25 , wherein the hazardous state is harsh braking and the alternate value is a suspension setting.
