Vehicle lean and alignment control system

A frame and suspension for a vehicle comprising:

• a frame having a central longitudinal axis and an upright axis;
• a suspension comprising a plurality of arm assemblies connected to the frame;
• wherein each arm assembly comprises:
• a lower arm having an inboard end and an outboard end;
• an upper control arm having an inboard end and an outboard end;
• and
• an actuator motively connected to the upper control arm, wherein the actuator further comprises:
• an actuator arm pivotally connected to the inboard end of the upper control arm;
• and
• an actuator motor supported on the lower arm and motively connected to the actuator arm to move the actuator arm through a range of motion.

A vehicle with a lean and alignment control system, comprising:

• a frame having a central longitudinal axis and an upright axis that is adapted to be generally perpendicular to a surface on which the vehicle rests when the frame is in a neutral position with no net leaning loads applied;
• a vehicle body supported on the frame;
• a suspension comprising a plurality of arm assemblies connected to the frame:
• wherein each arm assembly comprises:
• a lower arm having an inboard end and an outboard end;
• an upper control arm having an inboard end and an outboard end;
• and
• an actuator mounted to the lower arm and motively connected to the upper control arm, wherein the actuator further comprises:
• an actuator arm pivotally connected to the inboard end of the upper control arm;
• and
• an actuator motor motively connected to the actuator arm to move the actuator arm through a range of motion.
