摘要： A vehicle travel control device (10) includes: an EPS device (50) turning a wheel (5) of a vehicle (1); a VGRS device (30) capable of changing a ratio of a steering wheel angle (ϕs) and a steering angle of the wheel (5); and a control device (100) performing autonomous driving control that controls autonomous driving of the vehicle (1). The autonomous driving control includes: target steering angle calculation processing that calculates a target steering angle (δa) of the wheel (5); turning control that actuates the EPS device (50) to turn the wheel (5) such that the steering angle of the wheel (5) becomes the target steering angle (δa); and steering wheel angle control that actuates, based on the target steering angle (δa), the VGRS device (30) in a direction to suppress a change in the steering wheel angle (ϕs) caused by the turning control.

摘要： An electric power steering device (1), comprises an electric motor (15) which is supplied with power from a power supply device (70) to generate a predetermined steering assistance force for a steered wheel (FWl, FW2), and an assistance control device (30) which controls the amount (las) of electrical power supplied to the electric motor (15), according to the steering state of a steering wheel (11). The assistance control device (30) detects the power supply voltage of the power supply device (70). The assistance control device (30) controls the electrical current (las) supplied to the electric motor (15), so as to maintain the power supply voltage greater than or equal to a set voltage (VO) which is set in advance.

The autonomous driving control includes: calculating a target steering angle (δa) of the wheel (5); and actuating the EPS device (50) to turn the wheel (5) such that a steering angle of the wheel (5) becomes the target steering angle (δa). The calculating the target steering angle (δa) includes: calculating an autonomous driving steering angle (δb) and a target state quantity (ST) required for automatic steering in the autonomous driving; calculating a counter steering angle (δc) required for vehicle stabilization control, based on the target state quantity (ST) without using a steering wheel angle (cps); and calculating a sum of the autonomous driving steering angle (δb) and the counter steering angle (δc) as the target steering angle (δa).
