Abstract
A new and novel device for controlling a steering characteristic of a vehicle such as automobile so as to enhance an effect of suppressing a change in a behavior of the vehicle body due to a difference between driving and braking forces on the left and right wheels is characterized in that the device makes an amount of controlling the steering characteristic smaller as an index indicating an amount of a shift of vertical loads between the left and right wheels is increased. The steering characteristic is modified through controlling steering assist torque or a steering angle of the steered wheels. The steering assist by the steering control device is fully effective when the vehicle is running on a straight road having surfaces of different frictional coefficients while less effective on a curved road having a uniform frictional surface, preventing undesirable and unexpected modification of the steering characteristic during turning of the vehicle.
