Abstract
A vehicle control apparatus is provided. The apparatus comprises a sensor to detect a steering torque applied to a steering shaft that rotates in accordance with a steering wheel operation; a steering assistance unit configured to assist steering by a lane keeping assistance function; a correcting unit configured to obtain a corrected torque by removing a torque caused due to the steering assistance unit from the steering torque detected by the sensor; and a determining unit configured to determine whether or not a driver is in a hands-off state based on the corrected torque.
Claims7
A vehicle control apparatus comprising:
- a sensor configured to detect a steering torque applied to a steering shaft that rotates in accordance with a steering wheel operation;
- a steering assistance unit configured to assist steering by a lane keeping assistance function;
- at least one processor;
- and
- at least one memory storing a program which, when executed by the processor, causes the at least one processor to operate as:
- a correcting unit configured to obtain a corrected torque by removing a torque caused due to the steering assistance unit from the steering torque detected by the sensor;
- and
- a determining unit configured to determine whether or not a driver is in a hands-off state based on the corrected torque,
- wherein a frequency component lower than a predetermined frequency of the steering torque detected by the sensor is removed by a filter, and
- wherein an offset torque component caused due to a universal joint that forms a bent portion of the steering shaft is removed by removing a frequency component, of the steering torque detected by the sensor, that is lower than a predetermined frequency using a filter.
A vehicle on which a vehicle control apparatus is mounted, the vehicle control apparatus comprising:
- a sensor configured to detect a steering torque applied to a steering shaft that rotates in accordance with a steering wheel operation;
- a steering assistance unit configured to assist steering by a lane keeping assistance function;
- at least one processor;
- and
- at least one memory storing a program which, when executed by the processor, causes the at least one processor to operate as:
- a correcting unit configured to obtain a corrected torque by removing a torque caused due to the steering assistance unit from the steering torque detected by the sensor;
- and
- a determining unit configured to determine whether or not a driver is in a hands-off state based on the corrected torque,
- wherein a frequency component lower than a predetermined frequency of the steering torque detected by the sensor is removed by a filter, and
- wherein an offset torque component caused due to a universal joint that forms a bent portion of the steering shaft is removed by removing a frequency component, of the steering torque detected by the sensor, that is lower than a predetermined frequency using a filter.
