Problems solved by technology

However, this car can only give an alarm reminder to the driver on his own car when overtaking, and cannot give an alarm reminder to the driver of the vehicle in front at the same time, and there will still be a problem that the vehicle in front ignores the rear overtaking and causes a wrong operation to cause a traffic accident.

Embodiment 1

[0028] Embodiment 1: An overtaking early warning control system, its circuit principle connection diagram is as follows figure 1 As shown, it includes an overtaking early warning controller 1, an overtaking early warning device 2, a first fuzzy controller 3, a second fuzzy controller 4, a ranging sensor 5, a steering switch 6 and an ambient light sensor 7. The first fuzzy controller is connected to the distance sensor and steering switch, the second fuzzy controller is connected to the first fuzzy controller and the ambient light sensor, and the overtaking warning controller is connected to the first fuzzy controller, the second fuzzy controller and the overtaking warning device. Wherein the distance measuring sensor is an ultrasonic distance measuring sensor, and the early warning device includes a low beam, a high beam and a horn.

[0029] The overtaking early warning control method comprises the following steps:

[0030] In the first step, the first fuzzy controller takes ...

Embodiment 2

[0038] Embodiment 2: An overtaking early warning control system and control method, its circuit principle connection diagram is the same as that of Embodiment 1, and its control method is different from Embodiment 1 in that the seventh step is to obtain the precise control value V, and the second The fuzzy controller takes the control quantity V as the input quantity, and the control quantity V is divided into two levels, expressed in vocabulary as: {zero (ZO), positive (PB)}; the second fuzzy controller takes the external ambient light S as the input quantity , and the amount of external ambient light S is divided into 3 levels, expressed in vocabulary as: {negative (NB), zero (ZO), positive (PB)};

[0039] It also includes the eighth step, positioning the discourse domain of the control quantity V at 2 levels: {0, 1}, and positioning the discourse domain of the external environment light S at 3 levels: {-1, 0, 1}; the external environment light S The universe of discourse va...

Abstract

The invention discloses an overtaking warning control system and an overtaking warning control method. The overtaking warning control system comprises an overtaking warning controller, an overtaking warning device, a first fuzzy controller, a second fuzzy controller, a distance measuring sensor, a change-over switch and an environmental opto-sensor, wherein the first fuzzy controller is connected with the distance measuring sensor and the change-over switch; the second fuzzy controller is connected with the first fuzzy controller and the environmental opto-sensor; and the overtaking warning controller is connected with the first fuzzy controller, the second fuzzy controller, and the overtaking warning device. According to the overtaking warning control system and the overtaking warning control method, under a dangerous situation, the overtaking warning controller can effectively warn a driver of a front right car by flashing a high beam and a low beam, honking and the like to the driver of the front right car through fuzzily computing the fore-and-aft distance between the car adopting the overtaking warning controller and the front right car, the state of the change-over switch, the quantity of light of the outside surroundings, so that traffic accidents can be avoided; meanwhile, a fuzzy algorithm provided by the invention can be adjusted flexibly, and has high practicability.

Description

technical field [0001] The invention relates to the field of automobile active safety, in particular to an overtaking early warning control system and a control method. Background technique [0002] With the increase in the number of cars, traffic accidents frequently occur due to the wrong driving habits or negligence of the driver, and the failure to effectively remind the vehicle in front during the overtaking process occurs frequently. Overtaking early warning control system and control method. Chinese Patent Publication No. 1305910, date of publication August 1, 2001, discloses a kind of automobile anti-collision alarm device on expressway in the invention patent titled "automobile anti-collision alarm device on expressway". The alarm and the overtaking alarm device are connected through the uplink and downlink coding control switches and connected to the power supply. This invention can accurately display the number of vehicles in front, continuously and dynamically ...
