摘要： Provided is a vehicle cruise control device 10 that performs trajectory control for causing a vehicle to travel along a traveling road by steering vehicle wheels. The vehicle cruise control device includes: a roll control device (active stabilizers 56 and 58, etc.) configured to control a lateral-direction inclination angle of a vehicle body; and an inclination angle estimation device (a roll rate sensor 72, a stroke sensor 74i, etc.) configured to determine a lateral-direction inclination of a traveling road. When the trajectory control is executed in a situation in which the vehicle travels on a laterally inclined traveling road (S150, S250, S300, S500), the lateral-direction inclination angle of the vehicle body is controlled by the roll control device so that the lateral-direction inclination angle of the vehicle body is greater than 0 and smaller than the lateral-direction inclination angle of the traveling road (S450).

摘要： In a vehicle equipped with a power steering device for assisting the steering of the steered wheels by the steering wheel, when the steering angle of the steered wheels reaches the maximum steering angle, a steering control device restricts a target steering angle for operating the power steering device so that the steering angle or a reaction force acting against the power steering device does not exceed a value determined therefor, so to maintain the steering condition of the steered wheels stably without applying an excessive load on the power steering device. The target steering angle may be calculated as a value based upon rotational angle of the steering wheel and turning behavior control of the vehicle.

摘要： In a vehicle including a VGRS actuator capable of changing the steering transmission ratio by rotating an upper steering shaft and a lower steering shaft relative to each other, an ECU performs a lock releasing process when the VGRS motor is locked. In the process, an actual steering angle is calculated, and is compared with a lock release threshold value that is set in advance in view of the axial force applied to the lower steering shaft during steering. If the actual steering angle is equal to or smaller than the lock release threshold value, the ECU performs driving control of a lock mechanism so as to release the locked state of the VGRS motor.
