Problems solved by technology

Although this type of control technology has a certain effect on the safe driving of vehicles with punctured tires, there are some shortcomings in this type of technology. Firstly, after the punctured tires, the vehicle is braked in time to decelerate the vehicle, but there is no control over the direction of the vehicle, and the control of the vehicle direction is still completely controlled by the vehicl

Embodiment Construction

[0011] The invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0012] Such as figure 1 Said, the car tire blowout control method first carries out tire pressure detection, when detecting a blowout situation, immediately enters the process of judging whether the vehicle is in a turning state, the process includes steering wheel angle judging process, yaw angular velocity judging process, center of mass side The deflection angle judgment process and the trailing vehicle distance judgment process. First, the steering wheel angle judgment process is carried out. When the steering wheel angle is greater than the set value, the ESP braking operation is started. When the steering wheel angle is smaller than the set value, it enters the yaw rate judgment process. When the yaw rate is less than the set value, it will enter the center of mass side slip angle judgment process. When the mass center side slip angle ...

Abstract

The invention discloses a method for controlling tire burst of an automobile. The method deals with tire burst accidents occurring under straight travel condition and tire burst accidents occurring under cornering travel condition by reasonably starting ABS brake operation or ESP brake operation, such that not only extra hardware devices are not needed to add, but also the original braking force system is not needed to change, and service efficiency of the control device of the original automobile is further improved, so the method is convenient to implement. Both the ABS brake operation and ESP brake operation can help the driver to control the direction; therefore, the driver can control traveling direction of the automobile well in the event of tire burst of the automobile. At the same time, pretightening security protection of a pretightened safety belt and a forwarded headrest can greatly increase the degree of security protection to the driver, such that traveling safety of the automobile is higher.

Description

technical field [0001] The invention relates to a control method for safe running of a car, in particular to a control method when a tire blows out during the running of the car. Background technique [0002] If a tire blows out while the car is running, it will easily cause the vehicle to deviate from the normal driving track, thereby causing traffic accidents. Existing safety control technology for automobile tire blowout already has the functions of tire blowout monitoring and safety control. The tire blowout safety control technology is realized through the electromechanical integration system. When a tire blowout emergency occurs, the tire pressure monitoring sampling unit can immediately collect the blowout signal and transmit the signal to the microprocessor immediately. After the microprocessor performs logic operations, it sends instructions to the brake unit and taillights. The brake unit bursts out with a powerful braking force instantly, and immediately after th...
