Abstract
An embodiment driving assistance system for a vehicle includes a driving information provision unit configured to acquire and provide driving information of a traveling vehicle, a control unit configured to generate and output a control signal for driving assistance when it is determined the vehicle travels on a rough road based on the driving information of the vehicle provided by the driving information provision unit and it is determined that the vehicle is currently in a rough road traveling state, and a steering actuator configured to generate and apply a steering assistance force according to a control value of the control signal for the driving assistance output by the control unit to a steering wheel.
Claims18
A driving assistance system for a vehicle, the driving assistance system comprising:
- a driving information provision unit configured to acquire and provide driving information of a traveling vehicle;
- a control unit configured to generate and output a control signal for driving assistance when it is determined the vehicle travels on a rough road based on the driving information of the vehicle provided by the driving information provision unit and it is determined that the vehicle is currently in a rough road traveling state;
- and
- a steering actuator configured to generate and apply a steering assistance force according to a control value of the control signal for the driving assistance output by the control unit to a steering wheel,
- wherein the control unit is configured:
- to calculate a power spectrum density (PSD) value at an interval of a first setting time using a root mean square (RMS) value calculated from a signal value of a sensor for the first setting time, wherein the sensor is configured to detect vehicle state information of the vehicle,
- to calculate a sum power spectrum density (SPSD) value by summing and cumulating the PSD values for a predetermined second setting time, and
- to determine a recommendation speed corresponding to the calculated SPSD value.
A driving assistance system for a vehicle, the driving assistance system comprising:
- a driving information provision unit configured to acquire and provide driving information of a traveling vehicle, wherein the driving information provision unit comprises:
- a road surface information acquisition unit configured to acquire road surface state information of a road traveled by the vehicle;
- and
- a sensor configured to detect vehicle state information of the vehicle;
- a control unit configured to generate and output a control signal for driving assistance when it is determined the vehicle travels on a rough road based on the driving information of the vehicle provided by the driving information provision unit and it is determined that the vehicle is currently in a rough road traveling state;
- and
- a steering actuator configured to generate and apply a steering assistance force according to a control value of the control signal for the driving assistance output by the control unit to a steering wheel,
- wherein the control unit is configured:
- to calculate a power spectrum density (PSD) value at an interval of a first setting time using an RMS value calculated from a signal value of the sensor for the first setting time,
- to calculate a sum power spectrum density (SPSD) value by summing and cumulating the PSD values for a predetermined second setting time, and
- to determine a recommendation speed corresponding to the calculated SPSD value.
A driving assistance system for a vehicle, the driving assistance system comprising:
