The vehicle-mounted
safety control apparatus includes a first function of detecting an object ahead of the vehicle, a second function of acquiring, as a
time to collision, a ratio of a relative speed to a relative distance between the vehicle and the object, a third function of performing an automatic
brake operation when the
time to collision is smaller than or equal to a predetermined time, a fourth function of detecting acceleration of the vehicle, and a fifth function of acquiring, as a collision acceleration, acceleration detected within a period having a predetermined duration and straddling a time at which the
time to collision becomes 0, and operating to continue the automatic
brake operation if the collision acceleration is larger than or equal to a collision threshold preset to a value larger than acceleration produced by the automatic
brake operation, and otherwise terminate the automatic brake operation.
