The rocker sensor of the throttle valve actuating mechanism transmits signals to the cruise control unit, and the MCU controller and the engine ECU control unit exchange data through a CAN line.
The second embodiment is as follows:
the actuating mechanism is connected with the infrared radar probe and the indicating lamp. The longitudinal safe distance model refers to a longitudinal safe distance model for the road condition corresponding to the selection and establishment of the pedestrian in front of the driver. The safe distance model is divided into three distance phases: a safe driving distance Ss, a reminding alarm distance Sr and an emergency auxiliary braking distance Se. The system receives the distance between the pedestrian and the front pedestrian in real time, compares the distance with the three-section state distance, and makes different reactions according to different distance conditions. The safe driving distance Ss means that the automobile normally drives, and a system display displays that no pedestrian exists in front of the automobile, so that the automobile can safely drive; the reminding alarm distance Sr gives sufficient reaction time to the driver and can be used for carrying out correct habitual operation, after the reminding alarm distance is entered, an audible and visual alarm device of the system can give an alarm to remind the driver to pay attention, the driver takes corresponding measures to recover to the safe distance and stops giving the alarm, if the driver does not take the corresponding measures, a system display displays that pedestrians in front of the vehicle are going to pass through and pay attention to the safety, the audible and visual alarm carries out continuous alarm, and along with the reduction of the distance, the sound of a buzzer is sharp, and the flashing frequency of an alarm indicator lamp is increased; and after the emergency auxiliary braking distance Se is reached, the system automatically controls the auxiliary braking system to brake the automobile, and the automobile is completely braked when the automobile is away from the front pedestrian by the shortest safety distance Sm.
When the automobile runs at a non-traffic signal lamp intersection, pedestrians walk at different positions of the zebra crossing, the system can identify the position of the zebra crossing in front, and can judge the road surface condition of the pedestrian to establish an automobile safety distance model, starting from active protection, the system can implement two aspects of longitudinal anti-collision courtesy pedestrian and transverse pedestrian area detection courtesy protection, reduce the occurrence probability of traffic accidents, and ensure the health and safety of the pedestrian. The vehicle speed sensor, the accelerator pedal position sensor, the throttle valve rocker sensor and other sensors used by the system comprehensively sense the driving state of the driver, and can feed back the driving state to the central processing unit according to the image signal processing result, so that the false alarm rate and the false alarm rate can be timely reduced. According to the judgment result of the auxiliary control system, the system can work in the detection range of the infrared radar probe, if no pedestrian in front crosses the zebra crossing, the detection signal can be automatically closed, the signal interference is reduced to a certain extent, and the passing performance of the vehicle is ensured. The implementation is carried out by taking a series of approaches of investigation, overall design, hardware and software design, addition, testing, device determination, and application.
The intelligent auxiliary control method for automobile courtesy pedestrians comprises the following steps:
the method comprises the following steps: the method comprises the steps of establishing different automobile safety distance models according to different positions of pedestrians on zebra crossings, monitoring pedestrians and bicycle riding personnel who are in front and have pedestrian collision prevention and vision blind areas of drivers on two sides, measuring the distance, speed difference and the like of a traveling vehicle by adopting an infrared radar ranging probe, warning the drivers by an acousto-optic system in a general condition, and carrying out emergency auxiliary speed reduction and yielding in an emergency condition.
Step two: the infrared radar probe detects pedestrians in the range area, timely reminds a driver, and takes a series of courtesy measures. The driving state of a driver is comprehensively sensed by sensors such as an automobile speed sensor, an accelerator pedal position sensor, a throttle valve rocker sensor and the like, so that the false alarm rate and the false alarm rate are reduced. The system works in the detection range of the infrared radar probe, and is automatically closed when no pedestrian detection signal exists in front.
Step three: when a pedestrian needing to be given ceremony is detected, the controller MCU transmits signal data to the engine ECU through the CAN-H, sends a signal to the oil sprayer to control the oil sprayer to reduce/increase the oil spraying amount, transmits data to the cruise control unit through the CAN-H, transmits an instruction to control the throttle servo motor, and reduces/increases the throttle opening; the mixed gas is reduced/increased by controlling the fuel injection quantity and the opening degree of a throttle valve, so that the slow deceleration of the vehicle is realized, a signal is fed back to a controller MCU through a CAN-L, a display gives an alarm, and finally, the driver takes active treatment. After passing through the zebra crossing, when the speed is reduced and increased again, the speed is controlled to be recovered to the original speed by the self-adaptive cruise system.
Step four: and when the vehicle controller module detects that the automobile needs to give way to the pedestrian again, repeating the steps from the first step to the third step.
It is only a car ceremony pedestrian intelligence auxiliary control system's preferred embodiment to go up, a car ceremony pedestrian intelligence auxiliary control system's scope of protection does not only confine to above-mentioned embodiment, and the technical scheme that all belongs to under this thinking all belongs to the utility model discloses a scope of protection.
