Field: Transport (Mechanical engineering)
Classification: CPC B | IPC B

Claim 0:
1. A vehicle system, comprising:
a steering system including one or more steering actuators configured to steer a plurality of steerable wheels of a vehicle and a steering controller principally constituted by a computer and configured to control the one or more steering actuators to control steering angles of the respective steerable wheels;
a longitudinal-force application system including a plurality of longitudinal-force application actuators configured to apply longitudinal forces respectively to one or more left-side wheels disposed at a left-side portion of the vehicle and one or more right-side wheels disposed at a right-side portion of the vehicle and a longitudinal-force controller principally constituted by a computer and configured to control the longitudinal-force application actuators to control the longitudinal forces applied respectively to the one or more left-side wheels and the one or more right-side wheels; and
an onboard power source device including a main power source and a secondary power source and configured to supply electric power to the longitudinal-force application system and the steering system,

wherein, when the main power source is in an abnormal state in which the main power source fails to supply electric power to the longitudinal-force application system and the steering system, the longitudinal-force controller controls the longitudinal-force application actuators to control a difference between the longitudinal force applied to the one or more left-side wheels and the longitudinal force applied to the one or more right-side wheels, thereby turning the vehicle.
