Title:
VEHICLE CONTROL BY PITCH MODULATION
Document Type and Number:
Japanese Patent JP2019017248
Kind Code:
A
Abstract:
To provide a method of stabilizing a front to rear direction of a vehicle with respect to movement on a ground surface in a specific direction.SOLUTION: A vehicle includes at least one front wheel and at least one rear wheel, and the front wheel is characterized by force perpendicular to an instantaneous direction of vehicle movement. A motor actuator drives each rear wheel, and a controller dominates one or more motor actuators so as to dynamically stabilize the vehicle even if the front wheel does not contact a ground surface according to a uniform control rule. Torque is applied to the rear wheel on the basis of a vehicle pitch or force applied to the front wheel perpendicular to a moving direction. Furthermore, periodic rotational modulation can be applied to the rear wheel, so that the torque stabilized on the basis of a detected response to either the vehicle pitch or the perpendicular force applied to the front wheel is provide. The right and left motor actuators can independently control a right rear wheel and a left rear wheel, respectively to cause the rear wheels to continue turning as dominated by user's steering even if the front wheel does not contact the ground.SELECTED DRAWING: Figure 3
