Abstract
A steering safety mechanism for an automotive vehicle includes a steering shaft, a steering rack for turning a tire in response to rotation of the steering shaft, a steering motor for rotating the steering shaft or oscillating the steering rack leftward and rightward, and an electronic control unit for controlling the motor. The motor is rotated in a direction which limits rotation of the steering shaft in dependence upon vehicle velocity and steering angle, or vehicle velocity alone. This makes it possible to prevent the vehicle from skidding sideways and rolling over when the driver turns the steering wheel too sharply.
