Zusammenfassung:PROBLEM TO BE SOLVED: To provide a preceding vehicle start notification device that gives suitable notice of a preceding vehicle start according to a tendency in degree of acceleration of a driver who drives during a start.SOLUTION: When a vehicle preceding to a local vehicle at a stop starts, it is determined whether an inter-vehicle distance L from the local vehicle reaches a reference inter-vehicle distance Ld for giving a preceding vehicle start notice. It is assumed that the local vehicle starts when the reference inter-vehicle distance Ld is reached, and an assumed catch-up time T in which the local vehicle catches up with the preceding vehicle is computed from a start acceleration af of the preceding vehicle, an average acceleration as of the local vehicle during the start, and the current inter-vehicle distance L between the preceding vehicle and local vehicle. When it is determined from the assumed catch-up time T that the local vehicle does not catch up with the preceding vehicle within a reference time t1, the driver is given a preceding vehicle start notice to know that the preceding vehicle has started, and urged to start the local vehicle. When it is determined from the assumed catch-up time T that the local vehicle will catch up with the preceding vehicle within the reference time t1, the preceding vehicle start notice is not given.
