Embodiment 1

[0046] This embodiment provides a method for determining the ejection timing of the seat, which can be run inside the vehicle controller, or in an additional controller that judges the ejection timing. like figure 1 shown, including the following steps:

[0047] S101: Obtain vehicle driving state parameters and pre-collision object state parameters; wherein the vehicle driving state parameters may include vehicle driving speed, vehicle driving acceleration, vehicle load, and the like. The state parameter of the pre-collision object may include any one of the velocity of the pre-collision object, the acceleration of the movement of the pre-collision object, the shape of the pre-collision object, the hardness of the pre-collision object, and the distance between the pre-collision object and the vehicle.

[0048] S102: Obtain an injury index according to the vehicle driving state parameters and the pre-collision object state parameters; in this step, the injury index can be calc...

Embodiment 2

[0057] like figure 2 As shown, this embodiment provides a seat ejection control method, which can run inside the vehicle controller, or run in an additional controller that judges the ejection timing, and can be used in conjunction with the method described in Embodiment 1. , including the following steps:

[0058] S201: Respond to the seat ejection instruction; the seat ejection instruction may be the instruction sent by S104 in Embodiment 1, or may be manually input. For example, when the driver encounters an unexpected situation while driving, the seat ejection function cannot be automatically performed. At this time, the driver can automatically trigger the seat ejection according to the actual situation, such as preset a trigger button for emergency use.

[0059] S202: Obtain a safe area suitable for landing, and obtain the safe angle and safe distance of ejection according to the current location of the vehicle and the location of the safe area; in current vehicles, el...

Embodiment 3

[0064] like Figure 4 As shown, this embodiment provides a seat ejection control method, as an improvement to the method in Embodiment 2, which specifically includes the following steps:

[0065] S401: Respond to a seat ejection command.

[0066] S402: Obtain a safe area suitable for landing, and obtain a safe angle and a safe distance for ejection according to the current location of the vehicle and the location of the safe area.

[0067] S403: Controlling the automatic defeat of the vehicle roof.

[0068] S404: Control seat ejection according to the safety angle and the safety distance.

[0069] S405: Obtain information about obstacles around the seat; acquire a safe direction according to the obstacle information; adjust the ejection angle of the seat so that the forward direction of the seat is consistent with the safe direction. In this step, the surrounding environment during the ejection process of the seat can be collected through the camera installed on the seat, a...

Abstract

The invention provides a method for determining seat ejection time and a seat ejection control method and system. According to the method and device for determining the seat ejection time, a damage index can be obtained according to a running state parameter of a vehicle and a pre-collision object state parameter, and when the damage index is higher than a set threshold, a seat ejection instruction is output. In the running process of the vehicle, if the vehicle collides with the pre-collision object, whether it is necessary to execute the seat ejection instruction or not is judged according to the running state parameter of the vehicle and the pre-collision object state parameter, and the two parameters are used as pre-damage information for judgment so as to obtain the damage index, seatejection is started only when the damage index reaches a certain degree, and larger damage caused by ejection is avoided.

Description

technical field [0001] The invention relates to the technical field of vehicle intelligent control, in particular to a method for determining a seat ejection timing, a seat ejection control method and a system. Background technique [0002] Automobile is an important means of transportation in people's daily life, and it is also one of the means of transportation with a high risk factor. Especially in the automobile running at high speed, in case of an accident, it is often because the speed is too high, resulting in car crash and death. [0003] As a means of escape, ejection seats have been widely used in the field of aircraft, especially fighter jets, but are rarely used in the field of automobiles. The main reasons are as follows: [0004] 1. Aircraft and automobiles face different ejection timings. The aircraft flies fast, and when the seat needs to be ejected, the collision between the aircraft and the ground must be a high-speed collision; however, there may be two ...
