Abstract
Provided is a steering reaction force control apparatus for a vehicle including a driving support device configured to control an electric power steering device via a controller so that a steered angle of steered wheels reaches a target steered angle. When the driving support device is operating, the controller calculates a target steering spring torque based on a corrected steering angle corrected by a target steering angle for driving support control. When the magnitude of the corrected steering angle is less than a reference value, the target steering spring torque is calculated so that the magnitude of the target steering spring torque becomes larger in a case where the driving support device is operating compared with a case where the driving support device is not operating.
Claims2
A steering reaction force control apparatus for a vehicle, which is to be applied to a vehicle having an electric power steering device and a driving support device configured to control the electric power steering device so that a steered angle of steered wheels reaches a target steered angle, the steering reaction force control apparatus comprising:
- a controller configured to control the electric power steering device and the driving support device;
- and
- the controller being configured to:
- acquire a steering indication value representing an actual steering operation amount of a driver;
- calculate a target steering reaction force including a target steering spring force that is based on the steering indication value;
- and
- control the electric power steering device so that a steering reaction force reaches the target steering reaction force;
- and
- calculate the target steering spring force based on the steering indication value when the driving support device is not operating and calculate the target steering spring force based on a corrected steering indication value acquired by correcting the steering indication value with a target steering indication value corresponding to the target steered angle when the driving support device is operating;
- wherein
- when a magnitude of the steering indication value for calculating the target steering spring force is less than a reference value, the controller is configured to calculate the target steering spring force so that a magnitude of the target steering spring force becomes larger when the driving support device is operating compared with when the driving support device is not operating wherein, when the magnitude of the steering indication value for calculating the target steering spring force is more than the reference value, the controller is configured to calculate the target steering spring force so that the magnitude of the target steering spring force becomes smaller when the driving support device is operating compared with when the driving support device is not operating.
