The invention provides a steering assistance device and a steering assistance method for a vehicle. The steering assist device for a vehicle includes a steering assist ECU. A steering assist ECU calculates a target steering angle for causing a vehicle to travel along a travel path, and calculates a target steering guide torque for guiding a driver to steer so that the actual steering angle becomes the target steering angle. The steering assist ECU controls the torque applying device so that the steering guide torque becomes the target steering guide torque. The steering assist ECU acquires at least one of information about the traveling environment of the vehicle and information about the state of the driver, and calculates an index value indicating the necessity of steering guide torque on the basis of the at least one of the information. The steering assist ECU corrects the target steering guide torque on the basis of the index value such that the target steering guide torque increases as the necessity of the steering guide torque increases.
提供一种车辆用操舵辅助装置及操舵辅助方法。所述车辆用操舵辅助装置包括操舵辅助ECU。操舵辅助ECU运算用于使车辆沿着行驶路行驶的目标操舵角,运算以使得实际的操舵角成为目标操舵角的方式引导驾驶员的操舵的目标操舵引导扭矩。操舵辅助ECU以使得操舵引导扭矩成为目标操舵引导扭矩的方式控制扭矩施加装置。操舵辅助ECU取得车辆的行驶环境的信息及关于驾驶员的状态的信息中的至少一方,基于至少一方的信息运算表示操舵引导扭矩的必要性的指标值。操舵辅助ECU以操舵引导扭矩的必要性越高则目标操舵引导扭矩越大的方式,基于指标值修正目标操舵引导扭矩。
