VEHICLE DRIVING SUPPORT CONTROL DEVICE

摘要

In a driving support system of a vehicle, there is provided a structure that, even during operating a control based on a machine input, a driver's sense of incongruity can be reduced as much as possible and/or the steering of the driver be can reflected. The vehicle is equipped with a steering assist mechanism and a braking-driving force distribution mechanism of right and left wheels. In operations of the inventive device, a steering assist torque, applied by the steering assist mechanism, is controlled to a target value determined with reference to a target steering torque to achieve the target route, determined without depending on steering of a driver, and a driver's steering torque; and a braking-driving force difference between the right and left wheels is controlled to a target value based on a steering angle of the driver.

主权项

1. A driving support control device of a vehicle equipped with a steering assist mechanism and a braking-driving force distribution mechanism of right and left wheels, comprising:
a target route determiner which determines a target route of the vehicle in the driving support control without depending on steering of a driver; a steering assist torque determiner which determines a target value of a steering assist torque to achieve a target steering torque determined based on the target route with reference to the target steering torque and a steering torque of the driver; a right and left wheels' braking-driving force difference determiner which determines a target value of a braking-driving force difference between the right and left wheels based on a steering angle of the driver; a steering assist torque controller which controls the steering assist torque applied by the steering assist mechanism to the target value of the steering assist torque; a right and left wheels' braking-driving force difference controller which controls the braking-driving force difference between the right and left wheels applied by the braking-driving force distribution mechanism of the right and left wheels to the target value of the braking-driving force difference between the right and left wheels.
