[0002] The side of the car has always been the weak area of the collision. There are many cases of car crashes caused by the frontal impact of the car on the side of the car, and there are very few studies on the safety of the side collision of the car at home and abroad, and only a few studies on the anti-collision warning , can not really play a role in protecting the safety of the driver and reducing the impact on the side impact

Embodiment Construction
[0032] Below in conjunction with accompanying drawing, the technical scheme of the present invention is described in further detail:
[0033] like figure 1 and figure 2 As shown in the figure, the present invention discloses a protection mechanism for a side impact of an automobile, comprising first to second radar speed sensors, first to second distance sensors, ECU, first to eighth fuel injection mechanisms, and fuel injection drive motors , injection master cylinder and oil storage cup;
[0034] The first to second radar speed sensors are respectively arranged on both sides of the car, and are used to measure the speed of an oncoming car from the side of the car and transmit it to the ECU;
[0035] The first to second distance sensors are respectively arranged on both sides of the car, and are used to measure the distance between the oncoming car and the car from the side of the car, and transmit it to the ECU;
[0036] The first to eighth fuel injection mechanisms are ...

The invention discloses a protection mechanism for lateral impact of a vehicle and a control method thereof. The protection mechanism comprises a first radar speed sensor, a second radar speed sensor, a first range sensor, a second range sensor, an ECU, first to eighth oil injection mechanisms, an oil injection driving motor, an oil injection master cylinder and an oil storage cup, wherein the first to eighth oil injection mechanisms are respectively arranged at two sides of four tires of the vehicle, and each oil injection mechanism comprises an oil injection common rail connected with the outlet of an oil injection master cylinder piston through a solenoid valve; the oil injection common rail is provided with a plurality of nozzles for injecting oil to the ground beside the tires of the vehicle; the oil injection driving motor is connected with the oil injection master cylinder piston through a screw rod; and an outlet of the oil storage cup is connected with an inlet above the oil injection master cylinder. During working, whether the lateral impact occurs or not is judged according to the measured data of the first and second radar speed sensors and the first and second range sensors, and if the lateral impact occurs, the oil injection driving motor and the solenoid valve of the corresponding oil injection mechanism are controlled to work.
Description
technical field [0001] The invention relates to the field of vehicle dynamics, in particular to a protection mechanism for side impact of a vehicle and a control method thereof. Background technique [0002] The side of the car has always been a weak area of collision. There are many cases of car crashes caused by the frontal impact of the car on the side of the car. Moreover, there are very few studies on the safety of car lateral impact at home and abroad, and only a few studies on collision avoidance warning. , and can not really play a role in protecting the driver's safety and reducing the impact of the lateral impact. This paper is based on the method of reducing the lateral force of the vehicle tire during impact, so as to buffer the lateral impact of the vehicle on the outside. And because the ground is reduced to provide lateral reaction force, the tendency of the vehicle to roll over is reduced. SUMMARY OF THE INVENTION [0003] The technical problem to be so...
