PROBLEM TO BE SOLVED: To provide a safety operation device and an operation method for a vehicle which is extremely low cost compared to the vehicle cost with practical and reliable means retaining suitable inter-vehicle distance even when partial manual operation by a driver is required.SOLUTION: When a vehicle is travelling, travelling distance information and speed information are obtained from a rotational pulse of a wheel and information on slipperiness of a road surface is inputted mainly by visual inspection. Safety driving is guided by calculating appropriate inter-vehicle distance or speed depending on an on-vehicle device and partial visual inspection from the information or by also using information from a device embedded on a road side, depending on a stop watch and/or a metronome function. Furthermore, stable following travelling is obtained by using a position servo type cruise control and automatic safe following travelling is carried out online especially when using information from the device embedded on the road side in the future. |
