An apparatus for grade severity detection in a motorized vehicle includes a first sensor and a second sensor that provides data to a controller. The first sensor is configured to generate motion data indicative of at least one wheel of the motorized vehicle. The second sensor generate data, which is indicative of torque for at least one wheel of the motorized vehicle. The controller is configured to calculate a pitch of the motorized vehicle based on the torque data and one or more acceleration values derived from the position data and configured to perform a comparison of the calculated pitch to a pitch threshold. A grade severity message is generated based on the comparison.

Grade severity detection

Disclosed is a system for providing vehicle indicator lights, such as brake lights for a bicycle or motorcycle. The system may include at least one indicator light, a gyroscopic sensor, an accelerometer, a power supply, and a signal processing unit that receives inputs from the gyroscopic sensor and the accelerometer and activates an indicator light based on inputs from the sensors. Various algorithmic functions and other features may also be included in the system to make detection more robust and the make the system useable for a variety of different vehicle applications.
