Abstract

An automobile cruise control method and a cruise device utilize an optical signal detection device to detect whether a steering lamp of a side vehicle on a bypass is turned on or not; when the steering lamp of the side vehicle is turned on, the speed of the side vehicle is detected by using a speed detector; a controller calculates the difference between the speed of a main vehicle and the speed of the side vehicle, and the difference is compared with the preset safe speed difference; when the calculated difference is less than the safe speed difference, an alarm is given for emergency braking; when the calculated difference is more than the safe speed difference, deceleration and braking are carried out to ensure that the automobile can keep the safe distance with the front vehicle, i.e.a new target vehicle as soon as possible; particularly when the calculated difference is far more than the safe speed difference, any measure is unnecessarily taken. The automobile cruise control method and the cruise device can accurately handle the condition according to the overtaking and lane-changing of the side vehicle, thereby effectively improving the usability and flexibility of the cruise device.

Description

technical field [0001] The invention relates to an automobile cruise control method and a cruise device. Background technique [0002] The existing intelligent cruise control system often takes emergency braking measures when a vehicle suddenly changes lanes from the side lane at an excessive speed, which will not only affect the service life of the vehicle, but also cause psychological pressure and stress on the owner due to emergency braking. Mental tension. In addition, when the vehicle on the side lane changes lanes and overtakes at a very high speed, emergency braking is completely unnecessary. Contents of the invention [0003] An object of the present invention is to overcome the disadvantage that the existing cruise system cannot make accurate response to the overtaking and merging situation of the side vehicle, and to provide a method for automobile cruise control. [0004] According to an automobile cruise control method of the present invention, wherein the cr...
