Control system and control method for controlling power steering apparatus |
摘要 |
In a control system for a power steering apparatus, in which a steering assist amount in a steering mechanism of a vehicle is controlled to a target assist amount, a vehicle speed sensor 41 for detecting a running speed V of the vehicle and a steering angle sensor 52 for detecting a steering angle ha of the vehicle are provided. A lateral acceleration calculation unit calculates a lateral acceleration GY from the vehicle speed V and the steering angle ha and further determines the product V.GY of the vehicle speed V and the lateral acceleration GY. A fuzzy logic calculation unit then sets the target assist amount in accordance with a fuzzy logic rule using the vehicle speed V and the product V.GY as input conditions (membership functions). This thereby provides a control system and control method for controlling a power steering apparatus which presents an optimum steering characteristic in response to the running condition of the vehicle.
