ANGLE AND ORIENTATION MEASUREMENTS FOR VEHICLES WITH MULTIPLE DRIVABLE SECTIONS

Techniques are described for measuring angle and/or orientation of a rear drivable section (e.g., a trailer unit (308) of a semi-trailer truck) relative to a front drivable section (e.g., a tractor unit (202) of the semi-trailer truck) using an example rotary encoder assembly (304, 400). The example rotary encoder assembly (304, 400) comprises a base surface (404); a housing (402, 404) that includes a second end (402B) that is connected to the base surface (404) and a first end (402B) that is at least partially open and is coupled to a housing cap (414) and a rotary encoder (312, 408) that is located in the housing (402, 404) in between the base surface (404) and the housing cap (414), where the rotary encoder (312, 408) includes a rotatable shaft (424) that protrudes from a first hole (306, 422, 426) located in the housing cap (414), and where a top of the rotatable shaft (424) located away from the rotary encoder (312, 408) is coupled to magnet(s).
