Embodiment Construction
[0034] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0035] Now that the requirements for car safety are getting higher and higher, more and more cars are equipped with ESP (Electronic Stability System), CAN (Controller Area Network), etc. The present invention makes full use of existing conditions, only by adding a distance sensor and an anti-rear-end collision ECU (electronic control unit), and can realize comprehensive and effective three-dimensional management for avoiding the occurrence of vehicle rear-end collision. For ease of understanding, the following describes the functions of electrical components in the prior art combined with their specific applications in the present invention.

The invention relates to a system and method for preventing tail-end collision of a vehicle. In the system, a tail-end collision preventing control unit (5) is used for obtaining the distance between the vehicle itself and a front vehicle according to a detecting signal sent to the front vehicle and a received detecting signal returned from the front vehicle, the sum of the distance between the vehicle itself and the front vehicle and the brake distance of the front vehicle and the brake distance of the vehicle itself is compared to obtain a comparing result. When the comparing result is that the brake distance of the vehicle itself is larger than the sum of the distance between the vehicle itself and the front vehicle and the brake distance of the front vehicle, a speed reduction instruction or a torsion reduction instruction is sent to an engine electronic control unit (4), or a brake instruction is sent to a vehicle body electronic stabilizing system electronic control unit (3). According to the system and method for preventing the tail-end collision of the vehicle, a distance sensor and the tail-end collision preventing control unit are added on the existing arrangement of the vehicle, and regarding the unsafe situation in driving, speed reduction, torque reduction and braking are adopted to achieve the aim of tail-end collision prevention.
Description
technical field [0001] The invention relates to the field of automotive electronics, in particular to a vehicle rear-end collision prevention system and method. Background technique [0002] With the substantial increase in car ownership, there are more and more novices, and rear-end accidents are emerging in endlessly. Statistics show that more than half of rear-end collisions are caused by drivers who react too slowly to brake. Therefore, how to effectively maintain the distance between vehicles, not just relying on the driver can effectively prevent the occurrence of rear-end collisions, and ensuring the safety of riding has become one of the standards for measuring vehicle safety. [0003] Most of the anti-rear collision devices that can be seen on the market are a kind of flashing light, although this flashing light can shorten the reaction time of the driver, it still relies on the reaction of the driver and cannot reliably keep the distance between cars. [0004] Al...
