Embodiment Construction

[0017] Some embodiments described herein generally relate to a three-wheeled vehicle having two rear wheels and one front wheel. figure 1 is an example of a three-wheeled vehicle 100 according to one embodiment. The rear portion 102 of the vehicle 100 includes two rear wheels 104 and an electric motor that drives the rear wheels 104 . The front 106 of the vehicle 100 includes a passenger compartment 108 and front wheels 110 . Front portion 106 is rotatable relative to rear portion 102 about a longitudinal axis such that front portion 106 can tilt during rotation.

[0018] According to various embodiments, the vehicle 100 utilizes a drive-by-wire system in which the steering, motor control, and tilt of the front 106 are controlled by a system of sensors, actuators, and computers. Steering wheel inputs as well as accelerator and brake inputs are received by an electronic control unit (ECU), which then calculates signals to send to the various actuators and motors that control ...

Abstract

A three-wheeled vehicle that includes: a single front wheel; two rear wheels; a passenger cabin; an electronic steering control unit; and a steering input device configured to send an electronic signal to the electronic steering control unit corresponding to an input received at the steering input device associated with turning the three-wheeled vehicle; wherein the electronic steering control unit is configured to counter-steer the front wheel in response to receiving the electronic signal, wherein the counter-steering of the front wheel initiates a leaning of the passenger cabin a direction of turning of the three-wheeled vehicle.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application No. 61 / 670,074, filed July 10, 2012, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to the field of vehicle technology, and in particular to steering and control systems for tilt-steer three-wheeled vehicles. Background technique [0004] In conventional systems, when a tilting trike initiates a turn, the cabin begins to tilt. The tilting of the cabin then mechanically countersteers the front wheels. However, very large forces are required to initiate the tilting of the vehicle. This places high loads on the tilt actuators of the vehicle. Contents of the invention [0005] One embodiment of the present disclosure provides a three-wheeled vehicle. The three-wheeled vehicle includes: a single front wheel; two rear wheels; a passenger compartment; an electronic steering control...
