Definitions
- the present invention relates to a two-wheeled vehicle. More particularly, the present invention relates to mounting of a lean angle sensor on the two-wheeled vehicle. BACKGROUND OF THE INVENTION
- Two-wheeled vehicles such as motorcycles, are generally provided with a lean angle sensor which detects a lean angle value of the vehicle in real time.
- Lean angle is an angle at which the vehicle is leaned at corners or while turning.
- the laid- down orientation of the vehicle may adversely affect an engine of the vehicle, safety of a rider and cause various issues such as fuel spilling from a fuel tank of the vehicle.
- the lean angle sensor detects the lean angle value of the vehicle and the same is displayed to the rider. Display of lean angle value to the rider helps him to assess his riding performance as well as avoid instances such as vehicle roll-over.
- the lean angle sensor is located away from a center of gravity of the vehicle. Further, the lean angle sensor detects only a tilt of the vehicle. Tilt is a rotation around a longitudinal axis of the vehicle. The calculation of the lean angle value, based only on the tilt of the vehicle, is not always accurate when the lean angle sensor is located away from the center of gravity of the vehicle. For example, during uphill or downhill conditions, the calculation of the lean angle should also include yaw and/or pitch of the vehicle. Yaw is rotation of the vehicle about a vertical axis. Pitch is rotation of the vehicle about a transverse axis.
- the existing art teaches calibration of the lean angle sensor to include the yaw and/or pitch of the vehicle.
- Such calibration of the lean angle sensors include setting an offset to compensate for the yaw and/or pitch of the vehicle.
- such calibrations are complex and even after such calibrations the lean angle value obtained by the lean angle sensor may not be accurate.
- a two-wheeled vehicle having a lean angle sensor comprising a head pipe and a main tube.
- the main tube extends rearwardly from the head pipe.
- the main tube has a first section which extends rearwardly from the head pipe and a second section which extends rearwardly and downwardly from the first section.
- the two-wheeled vehicle further comprises a lean angle sensor configured to detect a lean angle value of the vehicle.
- the lean angle sensor is mounted on the second section of the main tube and is communicatively coupled to an Electronic Control Unit (ECU).
- ECU Electronic Control Unit
- the detection of the lean angle corresponds to detection of tilt of the vehicle.
- Tilt is a rotation around a longitudinal axis of the vehicle.
- the lean angle sensor is mounted on the second section of the main tube in a region behind an engine of the vehicle in a vehicle front-rear direction and above an engine mounting bracket in a vehicle upward-downward direction such that the lean angle sensor is positioned near a center of gravity of the vehicle.
- the two-wheeled vehicle comprises a mounting unit for mounting the lean angle sensor on the second section of the main tube.
- the mounting unit comprises a vertical member and a horizonal member.
- the vertical member extends between a first end and a second end in a vehicle upward downward direction and is configured such that the lean angle sensor can be mounted on the vertical member.
- the horizontal member extends from the first end of the vertical member in a direction towards the second section of the main tube.
- the horizontal member is configured to be fixedly or detachably attached to the second section of the main tube.
- the present invention discloses a method for detecting a lean angle of a two-wheeled vehicle.
- the method comprises a step of receiving, by an electronic control unit, a lean angle value of the vehicle from a lean angle sensor.
- the lean angle sensor is mounted on a second section of a main tube.
- the main tube extends rearwardly from a head pipe of the vehicle and comprises a first section and the second section.
- the first section extends rearwardly from the head pipe and the second section extends rearwardly and downwardly from the first section of the main tube.
- the method further comprises a step of comparing, by the electronic control unit, the lean angle value of the vehicle with a pre-determined value.
- the method further comprises a step of performing, by the electronic control unit, a first action when the lean angle value is greater than the pre-determined value and a second action when the lean angle value is less than the pre-determined value.
- the first action comprises one or more of the following: (i) disabling one or more actuators responsible for mobility of the vehicle in a vehicle static condition or in a vehicle dynamic condition, (ii) transmitting the lean angle value to a speedometer which displays the lean angle value using one or more first colors, (iii) providing a haptic feedback to a driver of the vehicle, (iv) generating an audio alarm.
- the second action comprises transmitting the lean angle value to the speedometer which displays the lean angle of the vehicle using one or more second colors.
- the one or more actuators is an ignition switch of the vehicle and/or a fuel injection system.
- the haptic feedback is a vibration provided to a handlebar of the vehicle in a region where the driver grips the handlebar
