SYSTEMS AND METHODS FOR ILLUMINATION CONTROL AND DISTRIBUTION DURING A VEHICLE BANK

摘要

A bank angle of a vehicle can be accurately calculated using yaw axis data and roll axis data, and based on the calculated bank angle, vehicle illumination optics can be controlled to maintain a pattern of distributed light from the illumination optics to be generally horizontal. The calculated bank angle may be zeroed when the yaw axis data equals zero. The improved pattern of distributed light from the illumination optics illuminates a more natural field of view for the vehicle driver during a bank. In some embodiments, the vehicle illumination optics can include a primary illumination group and a plurality of side illumination groups.

1. An apparatus for calculating a bank angle value of a banking vehicle, the apparatus comprising:
an inertial measurement unit, the inertial measurement unit including a processor and at least one motion sensor operatively coupled to the processor; the processor programmed to: sample yaw rate data at a predetermined rate, the yaw rate data provided by the at least one motion sensor; compare the yaw rate data to a predefined minimum yaw rate and a predefined maximum yaw rate, and when the yaw rate data is between the predefined minimum yaw rate and the predefined maximum yaw rate, set a bank angle value to zero; and when the yaw rate data is not between the predefined minimum yaw rate and the predefined maximum yaw rate, calculate the bank angle value.
