Embodiment Construction

[0017] Such as Figure 1 ~ Figure 2 Shown is an early warning system for preventing collisions when the tailgate of a vehicle is opened, including a vehicle body control system BCM and a reversing sensor 1 , and the body control system BCM is connected to the reversing sensor 1 . The body control system BCM triggers the reversing radar 1 to turn on according to the rear door unlocking signal. The body control system BCM triggers the reversing radar 1 to be turned on according to the unlocking signal of the back door, and the reversing sensor 1 detects whether there is an obstacle within the range of the set value L of the horizontal distance behind the vehicle and the set value H of the height behind the vehicle, and passes the alarm when there is an obstacle Unit 2 gives an alarm, which can be sound, buzzer or display on the display screen, reminding the user that there is an obstacle behind the vehicle, the back door cannot be opened or a suitable space at the rear of the ve...

Abstract

The invention discloses a pre-warning system for preventing bumps during vehicle back door opening. The system comprises a vehicle body control system BCM and a car reversing aid system. The vehicle body control system BCM is connected with the car reversing aid system. The vehicle body control system BCM triggers the car reversing aid system to be started according to a back door unlocking signal; after the vehicle control system BCM triggers the car reversing aid system to be started according to the back door unlocking signal, the car reversing aid system detects whether a barrier exists within the range of a vehicle rear horizontal distance set value L and a vehicle rear height set value H, and an alarm is given when a barrier exists. The pre-warning system has the advantages that the opening space of a vehicle back door is ensured, and a vehicle back door is prevented from touching the barrier when opened; potential safety hazards, caused when the back door is opened, of passengers are lowered; by means of the function of the car reversing aid system, the cost is low; the vehicle has the intelligence and science and technology feeling.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an early-warning system and an early-warning method for preventing bumping when a vehicle backup door is opened. Background technique [0002] With the increase of car ownership and the acceleration of urbanization, problems such as difficulty in finding parking spaces, few parking spaces, limited parking space or difficulty in parking in parking spaces have plagued the majority of car owners from time to time. Especially when parking in a narrow space, the owner may park the car and prepare to open the trunk to access items, but finds that the trunk cannot be opened due to space constraints, or the rear space of the vehicle is not well grasped, and the trunk is opened by remote control , the back door was bumped or scratched. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an early warning system and an early wa...
