Motorcycle with haptic braking hazard alert
Haptic devices are installed in a motorcycle's handlebars, footpegs and seat to provide the rider with alerts that relate to hazards. The alert is provided before the rider notices the hazard, or before the rider reacts to the hazard. By giving advance warning, a rider is given extra time to avert a potential accident. The alerts also provide a direct instruction to the rider as to what to do to avoid the accident.
1. A motorcycle comprising:
a haptic device mounted in a left handlebar of the motorcycle;
a haptic device mounted in a right handlebar of the motorcycle; and
a control unit connected to the haptic devices, the control unit configured to:
detect signals from multiple sensors attached to the motorcycle;
detect, from the signals, that a vehicle ahead of the motorcycle is braking;
detect, from the signals, that there is a vehicle behind the motorcycle;
detect, from the signals, whether there is sufficient space for the motorcycle to brake safely; and
activate the haptic devices in a first pattern when there is sufficient space for the motorcycle to brake safely and in a second pattern when the vehicle behind the motorcycle is too close for the motorcycle to stop safely.
2. The motorcycle of claim 1 , wherein:
the first pattern is a simultaneous, continuous activation of the haptic devices; and
the second pattern is a continuous activation of only one of the haptic devices.
3. The motorcycle of claim 2 , wherein the control unit is further configured to:
detect that the vehicle ahead of the motorcycle is traveling at a speed equal to a speed of the motorcycle and, in response, activate the haptic devices in a third pattern.
4. The motorcycle of claim 3 , wherein the third pattern is a repeated double pulse.
5. The motorcycle of claim 1 , wherein the control unit is further configured to compare the signals to thresholds stored in the control unit in order to detect whether there is sufficient space for the motorcycle to brake safely.
6. The motorcycle of claim 1 , wherein the control unit is further configured to:
compare the signals to thresholds stored in the control unit, wherein each threshold represents a hazardous condition, and at least some of the multiple sensors detect values of parameters of an environment in which the motorcycle is present, and at least some of the thresholds are based on the parameters;
activate at least one of said haptic devices when one of the thresholds is met; and
deactivate the activated haptic device or devices when the met threshold is no longer met.
7. The motorcycle of claim 6 , wherein at least one of the multiple sensors detects a parameter of a rider of the motorcycle, and at least one of the thresholds is based on the parameter of the rider.
8. The motorcycle of claim 6 , wherein:
the control unit comprises an interface connected to an engine control unit of the motorcycle;
the control unit is configured to obtain data regarding a state of the motorcycle; and
at least one of the thresholds is based on the state of the motorcycle.
9. A method for warning a rider of a motorcycle of a hazard, comprising:
receiving, by a control unit connected to the motorcycle, signals from multiple sensors attached to the motorcycle;
detecting, by the control unit, from the signals, that a vehicle ahead of the motorcycle is braking;
detecting, by the control unit, that there is a vehicle behind the motorcycle;
detecting, by the control unit, whether there is sufficient space for the motorcycle to brake safely; and
activating, by the control unit, a haptic device in each of a left and right handlebar of the motorcycle in a first pattern when there is sufficient space for the rider to brake safely or in a second pattern when the vehicle behind the motorcycle is too close for the motorcycle to stop safely.
10. The method of claim 9 , wherein:
the first pattern is a simultaneous, continuous activation of the haptic devices; and
the second pattern is a continuous activation of only one of the haptic devices.
11. The method of claim 10 , further comprising:
detecting, by the control unit, that the vehicle ahead of the motorcycle is traveling at a speed equal to a speed of the motorcycle; and, in response,
activating, by the control unit, the haptic devices in a third pattern.
12. The method of claim 11 , wherein the third pattern is a repeated double pulse.
13. The method of claim 9 , further comprising the control unit comparing the signals to thresholds stored in the control unit in order to detect whether there is sufficient space for the motorcycle to brake safely.
14. The method of claim 9 , further comprising the control unit:
comparing the signals to thresholds stored in the control unit, wherein each threshold represents a hazardous condition, at least some of the multiple sensors detect values of parameters of an environment in which the motorcycle is present, and at least some of the thresholds are based on the parameters;
activate at least one of the haptic devices when one of the thresholds is met; and
deactivate the activated haptic device or devices when the met threshold is no longer met.
15. The method of claim 14 , further comprising at least one of the multiple sensors detecting a parameter of the rider of the motorcycle, wherein at least one of the thresholds is based on the parameter of the rider.
16. The motorcycle of claim 14 , further comprising the control unit obtaining data regarding a state of the motorcycle, wherein at least one of the thresholds is based on the state of the motorcycle.
17. A kit of parts for attachment to a motorcycle, the kit comprising:
a haptic device configured to mount in a left handlebar of the motorcycle;
another haptic device configured to mount in a right handlebar of the motorcycle; and
a control unit configured to:
mount on the motorcycle;
connect to the haptic devices;
detect signals from multiple sensors attached to the motorcycle;
detect that a vehicle ahead of the motorcycle is braking;
detect that there is a vehicle behind the motorcycle;
detect whether there is sufficient space for the motorcycle to brake safely; and
activate the haptic devices in a first pattern when there is sufficient space for the motorcycle to brake safely and in a second pattern when the vehicle behind the motorcycle is too close for the motorcycle to stop safely.
18. The kit of parts of claim 17 , wherein the control unit is further configured to:
detect that the vehicle ahead of the motorcycle is traveling at a speed equal to a speed of the motorcycle and, in response, activate the haptic devices in a third pattern.
19. The kit of parts of claim 17 , wherein:
the control unit is further configured to compare the signals to thresholds stored in the control unit in order to detect whether there is sufficient space for the motorcycle to brake safely;
at least one of the multiple sensors detects a parameter of a rider of the motorcycle; and
at least one of the thresholds is based on the parameter of the rider.
20. The kit of parts of claim 17 , wherein:
the control unit is further configured to compare the signals to thresholds stored in the control unit in order to detect whether there is sufficient space for the motorcycle to brake safely;
the control unit comprises an interface for connection to an engine control unit of the motorcycle;
the control unit is configured to obtain data regarding a state of the motorcycle; and
at least one of the thresholds is based on the state of the motorcycle.
