Abstract
To smoothly switching the steering direction of the vehicle automatically driven along a road, leftward and rightward steering angles (.theta..sub.L, .theta..sub.R) are obtained on the basis of leftward and rightward white lines and by means of leftward and rightward cameras (7, 8) and image processors (9, 10) and a calculator (12), respectively. The obtained leftward and rightward steering angles are compared by a switching section (3). The steering angle output (.theta..sub.out) is switched to the leftward or rightward steering angle (.theta..sub.L, .theta..sub.R) only when both steering angles first roughly match each other, after the steering angle direction signal has been inputted to the switching section from another travel control unit.
