Pitch angle calculating device for vehicle
First Claim
1. A pitch angle calculating device for a vehicle, comprising:
- height detecting units arranged both in a front position and in the rear position of the vehicle, for detecting a vehicle height of the front position and a vehicle height of the rear position; and
a calculating section for calculating a pitch angle of the vehicle by the vehicle heights and a distance between the front position and the rear position;
wherein, on condition that the pitch angle is divided into a plurality of pitch angle ranges, the calculating section integrates periods residing in each pitch angle range and subsequently determines the pitch angle of the vehicle on a basis of the integrated periods referred as “
residence time”

Abstract
A pitch angle calculating device includes height detecting units arranged in front and rear positions of the vehicle for detecting front and rear vehicle heights and a calculating section for calculating a pitch angle of the vehicle by the vehicle heights and a distance between the front position and the rear position. In the device, the pitch angle is divided into a plurality of pitch angle ranges θ0˜θ1, θ1˜θ2, θ3˜θ4, . . . , the calculating section integrates periods residing in each pitch angle range and subsequently determines the pitch angle of the vehicle on a basis of the integrated periods referred as “residence time”. With the calculation, it is possible to avoid instantaneous changes in pitch angle due to the vehicle'"'"'s getting over irregularities and obstacles on a road.

2. A pitch angle calculating device for a vehicle, comprising:
-
a height detecting unit arranged in either one of a front position and the rear position of the vehicle, for detecting either a vehicle height of the front position or a vehicle height of the rear position; and
a calculating section for calculating a pitch angle of the vehicle by the vehicle heights and a distance between the front position and the rear position;
wherein, on conditions that the other of the vehicle heights is established by a fixed value and that the pitch angle is divided into a plurality of pitch angle ranges, the calculating section integrates periods residing in each pitch angle range and subsequently determines the pitch angle of the vehicle on a basis of the integrated periods referred as “
residence time”
