Abstract
A whoops-road determination device includes an acquisition unit configured to acquire a first value corresponding to pitch information related to pitch motion in a vehicle based on an output signal from a sensor mounted on the vehicle, a calculation unit configured to calculate a second value serving as a basis for determination whether a traveling road of the vehicle is a whoops-road from a time at which the first value crosses a first threshold, an accumulation unit configured to accumulate the second value as an accumulation value with passage of time, and a determination unit configured to determine whether the traveling road is the whoops-road based on the accumulation value.
Claims19
A whoops-road determination device comprising:
- an acquisition unit configured to acquire a first value corresponding to pitch information related to pitch motion in a vehicle based on an output signal from a sensor mounted on the vehicle;
- a calculation unit configured to calculate a second value serving as a basis for determination whether a traveling road of the vehicle is a whoops-road from a time at which the first value crosses a first threshold;
- an accumulation unit configured to accumulate the second value as an accumulation value with passage of time;
- and
- a determination unit configured to determine whether the traveling road is the whoops-road based on the accumulation value.
A vehicle control method comprising:
- an acquisition step of acquiring a first value corresponding to pitch information related to pitch motion in a vehicle based on an output signal from a sensor mounted on the vehicle;
- a calculation step of calculating a second value serving as a basis for determination whether a traveling road of the vehicle is a whoops-road from a time at which the first value crosses a first threshold;
- an accumulation step of accumulating the second value as an accumulation value with passage of time;
- a determination step of determining whether the traveling road is the whoops-road based on the accumulation value;
- and
- a control step of adjusting a damping force of a suspension of the vehicle.
