Vehicle integrated control method and system
A vehicle integrated control method includes determining a road surface status, determining a vehicle status, determining an integrated control mode by determining a control status of an electronic control suspension and a motion of a sprung mass and an unsprung mass based on the determination results of the road surface status and the vehicle status, and controlling the electronic control suspension and an in-wheel system by determining a control amount based on the determined integrated control mode.
Control system for a tiltable vehicle
A vehicle of the present disclosure may include at least one pair of opposing wheels coupled to a tiltable central chassis by a four-bar linkage or the like, such that the wheels are configured to tilt in unison with the central chassis. A steering actuator and/or a tilting actuator may be discretely controllable by an electronic controller of the vehicle. The controller may include processing logic configured to maintain alignment between a median plane of the chassis and a net force vector caused by gravity and any induced centrifugal forces. Various control algorithms may be utilized to steer the vehicle along a desired path, either autonomously or semi-autonomously.

CONTROLLING VEHICLE PITCH WHILE TOWING A TRAILER
Examples of techniques for controlling vehicle pitch while the vehicle is towing a trailer are disclosed. In one example implementation according to aspects of the present disclosure, a computer-implemented method includes detecting, by a processing device, a trailer attached to a vehicle. The method further includes responsive to detecting the trailer attached to the vehicle, detecting, by the processing device, a pitch event. The method further includes when a pitch event is detected, determining, by the processing device, whether the pitch event exceeds a pitch threshold. The method further includes, responsive to determining that the pitch event exceeds the pitch threshold, adjusting, by the processing device, a vehicle pitch control device associated with the vehicle to counteract the pitch event for the vehicle and the trailer.
