that is, only when the value of n increases to 5 in a very short time, can it be forced to brake. About automatic, its design idea is roughly the same as that of automatic brake. Calculation of collision time in order to calculate the collision time between the car and the obstacle in front, the relative speed between the car and the obstacle in front should be obtained first

when the data processing module does not brake forcibly, the parallel solenoid valve is closed. When the car driver steps on the brake board, solenoid valve 1 is opened, solenoid valve 2 and solenoid valve 3 are closed, so as to realize manual braking. Jing'an District UAV product research company

path planning includes global path planning and local path planning. Global path planning is to determine a feasible and relatively optimal global path according to certain rules and current environmental information when the global map is known. If the speed of the car is greater than 20km/h, judge whether the time when the car will collide at the current speed is less than 4 seconds. If so, count n value plus 1. When n is greater than 5, start forced braking

From the perspective of patent applications

nowadays, cars are constantly developing towards intelligence and high-speed, especially on highways. It is very common for cars to exceed 120 kilometers per hour, so in case of an accident, the reaction time left to people is very short. When the pressure sensor generates current to open the solenoid valve 1, the non gate circuit makes the solenoid valve 2 low and closes the solenoid valve 2, so that the high-pressure oil will not return to the oil pool during braking. Similarly, when the car driver releases the brake plate, solenoid valve 1 is closed, solenoid valve 2 and solenoid valve 3 are opened, the high-pressure oil generated by the oil pump and the oil of the brake drum flow to the oil pool, and the brake pads are released. Statistics show that automobile rear end collision accounts for the vast majority of highway traffic accidents, and highway serial rear end accidents also occur from time to time. The root cause is that the speed is too fast, and the human brain and body have no time to respond. The auto anti-collision system is designed to solve this problem. Driverless vehicle is a highly intelligent vehicle, and its automatic obstacle avoidance ability is also developed on the basis of the existing automatic collision avoidance system. Therefore, only after making the same judgment for many times can the brake be forced. When the frequency of laser beam emitted by the laser generator is times per second, it takes less than 0.1 second to make five judgments

the overall scheme design of automobile automatic anti-collision braking system includes three parts: data acquisition, data processing and action execution. The task of the data acquisition module is to collect all kinds of data to realize automatic collision avoidance. The task of the data processing module is to analyze whether there is a car in front and issue the corresponding or braking command. The task of the action execution module is to perform or forcibly brake

if the laser frequency emitted by the laser transmitter is t, the relative speed between the car and the obstacle in front is the reciprocal of the relative distance change multiplied by time, that is, the frequency, that is, the relative speed. Thus, the collision time between the car and the obstacle in front is the relative distance divided by the relative speed, that is, the time required for the collision. At present, the main conclusion of the commonly used vehicle control methods should adopt fuzzy reasoning, fuzzy PID, PID algorithm, meridians or the control technology combining many algorithms.
