Abstract
The invention aims at providing an automobile emergency brake alarm system and a control method thereof. The automobile emergency brake alarm system can timely and clearly notify vehicles, behind a vehicle performing brake, of the brake situation of the vehicle through a brake display lamp, thereby preventing the occurrence of rear-end collision accidents. The automobile emergency brake alarm system provided by the invention comprises a display device, an acceleration detection device, a brake pedal position detection device and a controller, wherein the controller is used for receiving signals of the acceleration detection device and the brake pedal position detection device, and controlling the display of the display device according to the signals. The control method of the automobile emergency brake alarm system is as follows: receiving the signals of the acceleration detection device and the brake pedal position detection device through the controller, and controlling the display device to display that the vehicle is in an emergency brake state by the controller when a brake pedal is trampled down and acceleration exceeds the preset acceleration.
Description
Technical field
The present invention relates to a kind of automobile emergency brake warning and control method thereof that is applicable to various brake and drive system for vehicle with tow.
Background technology
Brake system is the crucial active safety system of automobile, but present brake system can not be distinguished general brake and emergency brake, as long as step on brake pedal, the stoplight stop lamp of the tailstock will be bright, and the vehicle of back can't be judged whether emergency brake of front truck according to the situation of stoplight stop lamp, can only judge by the range estimation spacing, be easy to occur deviation.For example, when vehicle on the expressway, when perhaps running at high speed on the Ordinary road, when the place ahead emergency situations occurs or needs break turn, need emergency braking, regard common brake if rear car should brake, it is too late just might to occur braking, and causes knocking into the back.Therefore need a kind of device that front vehicle is informed on the things to know ground of emergency braking, make front vehicle can make early clearly judgement, take in advance effective scheme, to prevent the generation of rear-end collision.
Summary of the invention
The objective of the invention is to propose a kind of automobile emergency brake warning and control method thereof, the brake situation of this car in time can be informed front vehicle clearly by the brake display lamp, prevent the generation of rear-end collision.
Automobile emergency brake warning of the present invention comprises read out instrument, acceleration detecting, brake pedal position detecting device and controller, described controller receives the signal of acceleration detecting and brake pedal position detecting device, and comes the demonstration of control display device according to this signal.
The control method of above-mentioned automobile emergency brake warning is as follows: described controller receives the signal of acceleration detecting and brake pedal position detecting device, step on and acceleration/accel when surpassing predetermined acceleration when brake pedal, controller control display device shows that this car is in the emergency brake state.
Further, described controller also is connected with vehicle speed detector device, after increasing vehicle speed detector device, described controller receives the signal of acceleration detecting, brake pedal position detecting device and vehicle speed detector device simultaneously, when brake pedal is stepped on, acceleration/accel surpasses predetermined acceleration and the speed of a motor vehicle when surpassing preset vehicle speed, controller control display device shows that this car is in the emergency brake state.
Further, described controller is comprised of a comparator circuit and vehicle body control unit, to utilize existing parts, Cost reduction as far as possible.Comparator circuit degree of will speed up, brake pedal position, the speed of a motor vehicle and predetermined value compare, after only having acceleration/accel, brake pedal position, the speed of a motor vehicle all to meet the requirements, comparator circuit just inputs to signal of vehicle body control unit, and vehicle body control unit control display device shows.
Further, described read out instrument comprises stoplight stop lamp and assist brake lamp.Described controller shows that by lighting simultaneously stoplight stop lamp and assist brake lamp this car is in the emergency brake state, perhaps described controller is by lighting stoplight stop lamp, and the assist brake lamp that glimmers simultaneously shows that this car is in the emergency brake state, light the display area that the assist brake lamp can increase suddenly stoplight stop lamp, and the assist brake lamp of flicker also is enough to prompting prompting front vehicle.
Automobile emergency brake warning of the present invention is simple in structure, be convenient to control, the brake situation of this car in time can be informed front vehicle clearly by the brake display lamp, prevents the generation of rear-end collision, has good practicality.
