Abstract
An integrated chassis control method to improve driving stability may include mountain-road integrated chassis control allowing, when a road on which a vehicle drives is checked to be the route of a mountain road by an integrated chassis controller, electronic control suspension (ECS) damping force and all wheel drive (AWD) driving force distribution to be controlled in a different manner according to uphill and downhill roads due to a difference of elevation of the mountain road.
Claims14
An integrated chassis control method comprising:
- performing, by an integrated chassis controller, a mountain-road integrated chassis control of allowing electronic control suspension (ECS) damping force and all wheel drive (AWD) torque distribution to be controlled in a different manner according to uphill and downhill roads due to a difference of elevation of a mountain road, when a road on which a vehicle drives is verified to be a route of the mountain road by the integrated chassis controller,
- wherein normal integrated chassis control is performed according to a non-mountain road including a flatland when the route of the mountain road is not verified.
A vehicle comprising:
- an electronic control suspension (ECS) controller configured for controlling damping force of each of front- and rear-wheel suspensions;
- an all wheel drive (AWD) controller configured for controlling distribution of torque to each of front and rear wheels;
- an in-vehicle device including one of a navigation, a camera, and a vehicle sensor;
- and
- an integrated chassis controller connected to the ECS controller and the AWD controller and configured for performing mountain-road integrated chassis control allowing, when a route of a mountain road is verified based on information generated by one of the navigation, the camera, and the vehicle sensor, wherein ECS damping force and AWD torque distribution are controlled with the ECS controller and the AWD controller in a different manner according to uphill and downhill roads of the mountain road.
