Problems solved by technology

However, the existing active collision avoidance system requires the entire vehicle to be equipped with an electronic braking system, which increases production costs
In addition, the complexity and failure rate of the vehicle system are also increased due to the need to additionally install an electronic braking system

Embodiment Construction

[0017] In order to make the object, technical solution and beneficial technical effects of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific implementations described in this specification are only for explaining the present invention, not for limiting the present invention.

[0018] see figure 1 , which is a schematic diagram of the functional structure of the electric vehicle 99 provided in the embodiment of the present invention. The electric vehicle 99 includes a drive motor 91 , a motor controller 92 , a memory 93 , a processor 94 and an active collision avoidance system 100 for an electric vehicle. Wherein, the driving motor 91 is used to provide driving force and braking force. Specifically, the driving force is used to drive the electric vehicle 99 forward; the braking force is used to brake the electric vehicl...

Abstract

The invention provides an active anti-collision method for an electric automobile and further provides an active anti-collision system for the electric automobile. The active anti-collision method comprises the following steps that a starting instruction of a driver is detected, and a detecting instruction is generated when the starting instruction of the driver is detected; the real-time distancebetween the electric automobile and an obstacle is detected according to the detecting instruction; whether the real-time distance is smaller than a set distance or not is judged, and if yes, a decelerating instruction is generated; a driving motor is controlled to generate first braking force according to the decelerating instruction so as to control the electric automobile to decelerate; whether the real-time is smaller than a safety distance or not is judged, and if yes, a stopping instruction is generated; and the driving motor is controlled to generate second braking force according to the stopping instruction so as to control the electric automobile to further decelerate till the electric automobile is stopped. According to the active anti-collision method for the electric automobile, the production cost is reduced, the complexity of an automobile system is reduced, and the failure rate of the automobile system is decreased.

Description

【Technical field】 [0001] The invention relates to the technical field of electric vehicles, in particular to an active collision avoidance system and method for electric vehicles. 【Background technique】 [0002] With the continuous popularization of automobiles, people pay more and more attention to the safety of automobile driving. Various control systems, such as lane departure warning system, blind spot detection system, lane keeping system, parking automatic steering system and frontal collision prevention system, etc. Came into being. Among them, the active anti-collision system is very important. [0003] The active anti-collision function of the existing electric vehicle is to measure the distance through radar. When the vehicle distance exceeds the set safety distance, the vehicle control system controls the vehicle to slow down or stop through the electronic braking system. However, the existing active collision avoidance system requires the entire vehicle to be e...
