- the steering torque can be controlled so as to cancel the change in the steering torque based on at least one of the braking force and the driving force due to the stabilization control.
- At least one of the braking force and the driving force of the wheel is controlled.
- the change in the steering torque based on the stabilization control is canceled to prevent the steering filling from being deteriorated.
- the steering apparatus for a vehicle includes: a steering shaft that transmits torque applied by a driver for steering to wheels; and an actuator that generates torque that is added to the torque applied by the driver.
- the steering torque based on the change in at least one of the braking force and the driving force can be canceled smoothly by controlling the torque applied to the torque applied by the driver for steering.
- the variables corresponding to at least one of the braking force and the driving force of the vehicle due to the stabilization control include, for example, the braking force and the rotation speed of each wheel, the vehicle speed, the steering angle, and the distance between the vehicle and the road surface.
- the amount of change from the start of stabilization control such as the friction coefficient of the vehicle and the rate of movement of the vehicle, can be obtained, and the more various types of variables are obtained, the more accurately the change in steering torque can be canceled.
- the relationship between the variable and the change in the steering torque is determined so that the change in the steering torque can be obtained from the obtained variable by following the relationship.
- the change in the steering torque can be counteracted by adding a torque in the opposite direction that is equal in magnitude to the change in the steering torque based on the stabilization control and that is reversed.
- the steering assist torque in the direction is applied by the actuator It is preferably added.
- the braking force of the outer wheel is made larger than the braking force of the inner wheel, so that the vehicle is steered in the opposite direction to the steering direction of the vehicle.
- the steering assist torque in the same direction as the moment is applied by the actuator.
- FIG. 1 is a diagram illustrating the configuration of a steering apparatus according to an embodiment of the present invention.
- FIG. 2 is an explanatory view of the running state of the vehicle.
- FIG. 3 is a flowchart showing a control procedure of the steering apparatus according to the embodiment of the present invention.
- An input shaft 2 is connected to the ring wheel H, and an output shaft 4 is connected to the input shaft 2 via a torque sensor 3.
- the input shaft 2 and the output shaft 4 constitute a steering shaft that transmits torque imparted for steering by the driver to the wheels.
- the output shaft 4 is connected to a pinion 6 via a universal joint 5, and wheels 8 are connected to a rack 7 that matches the pinion 6.
- a steering angle sensor 9 is attached to the input shaft 2.
- a bevel gear 12 is fitted around the outer periphery of the output shaft 4, and is rotated by an actuator 13 by a bevel gear 15 that fits the bevel gear 12.
- the actuator 13 generates a torque that is added to the torque applied by the driver.
- a braking system is provided for braking each wheel 8 of the vehicle. That is, the master cylinder 17 generates a braking pressure corresponding to the depression force of the brake pedal 16. The braking pressure is amplified by the braking pressure control unit 18 and distributed to the braking device 19 of each wheel 8. Each brake device 19 applies a braking force to each wheel 8 based on the distributed braking pressure.
- the braking pressure control unit 18 is connected to a brake system controller 60 constituted by a computer.
- the brake system controller 60 includes a steering angle sensor 9, a sensor 52 for individually detecting the rotational speed of each wheel 8, a sensor 61 for individually detecting the braking force of each wheel 8, a vehicle and a road surface. And a friction coefficient sensor 62 for detecting a friction coefficient between them.
- the brake controller 60 amplifies and distributes the braking pressure in accordance with the rotation speed of each wheel 8 detected by the wheel speed sensor 52 and the feedback value by the braking force detection sensor 61.
- the braking pressure control unit 18 is controlled so that it can be operated. As a result, it is possible to individually control the braking force of the left wheel and the braking force of the right wheel.

- the relationship between the moment and the moment is calculated and stored in advance through experiments.
- the moment that causes the spin or drift is determined from the detected value of the variable correlated with the vehicle behavior and the stored relationship, and the spin-drift of the vehicle is calculated from the value of the moment. Determine the risk of occurrence. If there is a danger, control the braking force so that a moment in the opposite direction can be applied to the vehicle.
- FIG. 2 when the behavior of the vehicle 10 is stable at the time of steering, the vehicle travels on a substantially ideal route desired by the driver indicated by a broken line.

That is, the change in the steering torque is canceled by adding a torque having the same magnitude and the opposite direction as the change in the steering torque based on the stabilization control by the factories 13.
- the steering assist torque in the same direction as the moment is applied to the actuator.
- a change in the steering torque that causes the vehicle to steer in the opposite direction to the moment is applied. Therefore, a steering assist torque in the same direction as the moment indicated by the arrow B is added by the actuator 13.
- the steering torque may change in the opposite direction to the moment. From the module indicated by the arrow A A steering assist torque in the same direction as that of the gear is added by the actuary 13.
