Further, described alarm module comprises be used to the speech-chip that sends caveat and/or is used for sending the vibration seat of caution by vibration seat.
Further, the brake of described execution module control is comprised of controller, automatically controlled air pressure valve and gas circuit pipeline.
Automobile intelligent brake control system of the present utility model comprises the obstacle distance detection module, signal acquisition module, alarm module, execution module and central process unit, central process unit Real-time Collection vehicle accelerator pedal depth signal, the brake pedal depth signal, vehicle speed signal, the vehicle of steering indicating light signal and detection part feedback is apart from the range signal of the place ahead obstacle, calculate safety shut-down distance and emergency stopping distance according to current vehicle speed signal, then according to the quantity of the vehicle front obstacle of detection part feedback and the range information of vehicle and the place ahead obstacle, control alarm module and execution module work; When the distance that detects vehicle and the place ahead obstacle during less than safety distance and greater than emergency stopping distance, at first send low frequency early warning signal reminding driver by warning module and drive with caution; If control system can't detect active operation behavior that chaufeur takes (such as the accelerator releasing pedal, step on brake pedal, open steering indicating light), and the distance of vehicle and the place ahead obstacle is during less than emergency stopping distance, send the high frequency alarm signal, send simultaneously engine power and cut down signal, if the distance of vehicle and the place ahead obstacle is during still less than the emergency stopping distance that calculates under the current vehicle speed, then control execution module work, to reduce or to avoid automobile to have an accident, alarm module is based on the human body sense of hearing, vision and sense of touch are considered, adopt light, the caution action of caveat and vibration, mode is novel, and alarming effect is obvious; System not only can provide alarm signal when being about to have an accident, simultaneously where necessary can also the ACTIVE CONTROL brake system, realize the Based Intelligent Control of braking automobile, occured thereby reduce the auto against traffic accident that causes because of chaufeur carelessness or maloperation, improved the safety traffic of automobile.
Description of drawings
Fig. 1 is the system principle diagram of the utility model embodiment;
Fig. 2 is the brake control system constructional drawing of embodiment;
Fig. 3 is the control flow chart of embodiment.
The specific embodiment
The automobile intelligent brake control system mainly is comprised of obstacle distance detection module, central process unit, warning module, signal acquisition module, execution module as shown in Figure 1.What represent in the dotted line block diagram is that system passes through the car load associated control signal that communication bus or hardwired obtain.
The obstacle distance detection part: major part is comprised of camera or radar and data handler.By the travel traffic information in the place ahead of camera or radar collection vehicle, and process in real time related data (graphicinformation etc.) by data handler, whether the identification vehicle front has the distance between obstacle and vehicle and the place ahead obstacle.Then quantity and the vehicle with the vehicle front obstacle sends to control system apart from the real-time CAN bus of passing through of the information such as distance of the place ahead obstacle.
Central processor CPU: the vehicle of main vehicle accelerator pedal depth signal according to the signal acquisition module Real-time Collection, brake pedal depth signal, vehicle speed signal, steering indicating light signal and detection part feedback is comprehensively judged apart from the range signal of the place ahead obstacle.CPU calculates safety shut-down distance and emergency stopping distance according to current vehicle speed signal, then according to the quantity of the vehicle front obstacle of detection part feedback and the range information of vehicle and the place ahead obstacle, controls alarm module and execution module work.When the distance that detects vehicle and the place ahead obstacle during less than safety distance and greater than emergency stopping distance, CPU at first sends low frequency early warning signal reminding driver by warning module and drives with caution; If can't detect the active operation behavior that chaufeur takes (such as the accelerator releasing pedal, step on brake pedal or open steering indicating light), and the distance of vehicle and the place ahead obstacle is during less than emergency stopping distance, CPU sends the high frequency alarm signal, send simultaneously engine power and cut down signal, if the distance of vehicle and the place ahead obstacle is during still less than the emergency stopping distance that calculates under the current vehicle speed, then CPU control execution module work is slowed down or direct the brake to avoid vehicle to have an accident.
The CAN bus interface is mainly used in the communication of the information datas such as obstacle distance detection module, central process unit, execution module, alarm module, Engine ECU.
Signal acquisition module is used for gathering vehicle speed signal, throttle/brake pedal depth signal and turn sign, and sends to central process unit by the CAN bus interface.
Alarm module: be comprised of speech-chip and vibration seat, when CPU provided the low frequency alarm signal, speech features was sent the caveat that reminding driver drives with caution; When CPU provided the high frequency alarm signal, speech features was sent urgent caveat, and the while vibration seat begins vibration makes chaufeur take as early as possible associative operation.
Execution module: formed by controller, automatically controlled air pressure valve and gas circuit pipeline, specifically see Fig. 2,1 expression compressed air brake cylinder among Fig. 2,2 expression triple valves, 3 expression brake pedals, 4 expression brake discs, the automatically controlled air pressure valve of 5 expressions.When controller receives the brake control signal that CPU sends, according to the size of brake control signal, by the spool aperture that PWM controls automatically controlled air pressure valve, finish the control of brake system air pressure.The ABS of vehicle is according to the air pressure in the brake piping, and control vehicle tyre brake system is finished brake work.
Principle of work and step:
1, obstacle distance detection part collection vehicle road ahead information status at first, and it is processed;
2, the information data after the obstacle distance detection part will be processed feeds back to CPU;
3, the relevant information of the real-time collection vehicle speed signal of CPU and obstacle distance detection part feedback;
4, CPU calculates safety shut-down distance and emergency stopping distance according to current vehicle speed signal, then according to the vehicle of obstacle distance detection part feedback and the range signal of the place ahead obstacle, control alarm module and execution module work.The distance that detects vehicle and the place ahead obstacle as CPU is during less than safety distance and greater than emergency stopping distance, and CPU at first sends low frequency early warning signal reminding driver by warning module and drives with caution.After providing alarm signal, if CPU can't detect the active operation behavior of chaufeur, and the distance of vehicle and the place ahead obstacle also constantly reducing, and then CPU at first sends the torque request order to Engine ECU, reduces the output of engine power; If this moment vehicle and the place ahead obstacle distance during still less than the emergency stopping distance that calculates under the current vehicle speed, CPU at first judges whether to exist the active operation behavior of chaufeur, if can't detect the active operation behavior of chaufeur, then control execution module, start brake system, carry out the active brake, with the generation of Avoids or reduces vehicle collision accident.After providing alarm signal, if CPU detects the active operation behavior of chaufeur, then do not start initiatively brake control.
5, intelligent braking control system periodical duty is in the 1-4 state, and its control flow chart as shown in Figure 3.
