VEHICLE STEERING ASSIST DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18112134 titled 'VEHICLE STEERING ASSIST DEVICE
Simplified Explanation
- The patent application describes a vehicle steering assist device that helps the driver steer the vehicle along a desired path. - The device includes a steering assist ECU (Electronic Control Unit) that calculates a target steering angle for the vehicle. - It also calculates a target steering guide torque to reduce the return torque, which is the force that brings the steering wheel back to its neutral position. - The target steering guide torque helps the steering angle reach the target steering angle more easily, especially in areas where the steering angle is smaller than the target. - If the steering angular velocity (how fast the steering angle changes) is higher than the target steering angular velocity, the device calculates a target steering angular velocity control torque. - This control torque acts in the opposite direction of the steering angle changes, helping to stabilize the steering. - The device then controls a control steering torque generating device to generate a control steering torque that includes the sum of the target steering guide torque and the target steering angular velocity control torque.
Original Abstract Submitted
A vehicle steering assist device in which the steering assist ECU calculates a target steering angle for driving a vehicle along a traveling path, and is vehicle steering assist device that a calculates a target steering guide torque for facilitating the steering angle to become a target steering angle by reducing a return torque for urging the steering wheel to a neutral position in an area where the steering angle is smaller than the target steering angle, wherein when the steering angular velocity is higher than the target steering angular velocity, the steering support ECU calculates a target steering angular velocity control torque acting in a direction opposite to a direction in which the steering angle changes, and controls the control steering torque generating device so as to generate a control steering torque including a sum of the target steering guide torque and the target steering angular velocity control torque.
