The invention discloses a barrier warning device for intelligent vehicle turning. The barrier warning device comprises a controller power supply, a probe group, a first control module and a buzzer group, wherein the controller power supply is connected with a steering wheel through an angle sensor; the controller power supply is electrically connected with the probe group to control the probe group to be started to detect barriers; the first control module decodes detection signals of the probe group and sends instructions through a power line; the buzzer group starts up according to the instructions sent by the first control module; the controller power supply, the probe group, the first control module and the buzzer group are in electrical connection to achieve carrier communication. According to the barrier warning device, the warning device is controlled to start through the steering wheel, the probe group senses the barriers, buzzers give out beeps to remind a driver and pedestrians respectively, and a camera group is started to shoot the road surface conditions, so the barrier warning device can well assist the driver in knowing the barriers around a car. The warning device is simple in structure, easy to manufacture, low in cost, safe, practical, remarkable in effect and capable of effectively improving driving safety and has wide application prospect.
