Abstract
An on-vehicle control device includes: a control unit that controls an attitude of a vehicle based on a value of a behavior sensor that detects a behavior of the vehicle, and prohibits control based on the behavior sensor when the value of the behavior sensor exceeds a threshold; and a travel environment determination unit that determines a travel environment of the vehicle based on image information captured by a camera, and in which the control unit changes the threshold to a lower value based on the travel environment determined by the travel environment determination unit.
Claims6
An on-vehicle control device comprising:
- a control unit that controls an attitude of a vehicle based on a value of a behavior sensor that detects a behavior of the vehicle, and prohibits control via a control intervention based on the behavior sensor when the value of the behavior sensor exceeds a threshold;
- and
- a travel environment determination unit that determines a travel environment of the vehicle, wherein
- the behavior sensor is an acceleration sensor that detects a longitudinal acceleration of the vehicle,
- the control unit changes the threshold of the acceleration sensor to a lower value when the travel environment determination unit determines that a distance between the vehicle and an obstacle on a front side is longer than a distance stored in the on-vehicle control device,
- the control intervention is suppressible based on an incorrect value of the acceleration sensor while the vehicle is traveling on a road having no obstacle on the front side;
- and
- the travel environment determination unit includes at least a camera.
