Abstract: A radar device 10, mounted on a vehicle A, for repeatedly performing a measurement of a target at every predetermined measurement interval, comprising a transmitting and receiving part 14 for, in each of the measurement events, transmitting a measurement wave P, and receiving a reflection wave R thereof as a detection wave, and a controller 12 for controlling the transmitting and receiving part 14, wherein the controller 12 is configured to control the transmitting and receiving part 14 so that at least one of a length (T1, T2) of each of the measurement intervals and a signal strength (I1, I2) of each of the measurement waves P is changed with time.

Abstract: A braking device for a vehicle comprises an accelerator-opening detector, a distance detector, an obstacle detector, and an ECU which is configured to perform the process of executing automatic braking when the distance detected by the distance detector is a specified distance or less during traveling of the vehicle, cancelling the automatic braking when the accelerator opening detected by the accelerator-opening detector is a specified opening or greater, and prohibiting the cancelling of the automatic braking when the front obstacle is detected by the obstacle detector while the vehicle stops or travels at a low speed which is a specified speed or less. Thereby, the braking device for a vehicle which can surely reduce the damage caused by the vehicle's collision with the front obstacle can be provided.
