PURPOSE:To make smooth acceleration securable even in time of a lane change to an overtaking lane, by installing a car speed controlling device, which controls a self-speed so as to become a safety car-to-car distance on the basis of the self-speed and the car-to-car distance detected. CONSTITUTION:An automobile is provided with a car speed sensor 9 for detecting a self-speed, a winker switch 10 for detecting a lane change and a radar unit 11 for detecting a car-to-car distance with a preceding car. Each output out of the sensor 9, the winker switch 10 and the radar unit 11 is inputted into a microcomputer 13 and hereat processed in conformity with a processing flow chart. On the basis of the operation result, the microcomputer 13 changes a transmission gear ratio by a transmission actuator 15, while a throttle valve is operated by a throttle actuator 17, thus a car speed is controlled so as to secure the optimum speed. |
