Embodiment Construction

[0052] The structural principles of the present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0053] like figure 1 As shown, a method for calculating a vehicle's active collision avoidance distance and its device include: a vehicle-mounted radar system, a vehicle-mounted sensor system, a control unit, and a braking force actuator. In the vehicle-mounted radar system, the self-vehicle sensor system is connected with the control unit, and the detected real-time data is transmitted to the control unit, and the control unit transmits the control command to the actuator, and the actuator controls the brake pedal pressure of the vehicle, and the throttle valve. Opening size. The model of the on-board radar system is Disc Tiger X8S; the model of the vehicle acceleration sensor is a 52 MEAS sensor; the central control system uses Philco E8043NAVI.

[0054] The vehicle radar system of the present invention is...

Abstract

The invention discloses an active anticollision device of a vehicle and a calculating method of an anticollision distance. The device comprises a vehicle-mounted radar system, a self-vehicle sensor, an executing mechanism and a central control system, wherein the self-vehicle sensor and the vehicle-mounted radar system are connected with the central control system, and the central control system is connected with the executing mechanism connected with a self-vehicle; the CPU of the central control system receives each data of the sensor to judge a safe state and give out a necessary anticollision instruction. Through the active safe anticollision device and the method thereof, the safe state to which the self-vehicle belongs can be judged through the real-time data collected by a vehicle-mounted radar and a self-vehicle sensing system, and the occurrence of a vehicle accident can be effectively avoided under the circumstance that the mind state of a driver is bad or the driver does not pay attention to driving.

Description

technical field [0001] The invention relates to an active safety control system, in particular to a method and device for calculating an active safety distance of a vehicle. Background technique [0002] With the rapid development of China's automobile industry and the increase of the total number of automobiles, the number of traffic accidents and casualties across the country is also increasing. Therefore, the safety of automobiles has gradually become the focus of attention. [0003] The safety of automobiles is divided into two parts: "active safety" and "passive safety". Energy-absorbing body, airbags, and seat belts can only solve problems after accidents, so these systems can only be passive safety. Passive safety plays a protective role in collisions; active safety systems prevent traffic accidents in advance, and even It can ensure the safety of drivers and passengers, so active safety systems will attract more attention than passive safety systems.
