Problems solved by technology

If the collision causes the airbag ECU to trigger, the vehicle will suddenly cut off fuel and power, and the user may be surprised, and the airbag ECU must be replaced for subsequent maintenance, and the user may complain
[0006] 2) If the front, side and rear collision algorithm strategies are unreasonable, it will also affect the fuel and electrical cut-off algorithm
For example: see figure 2 , the after-collision point explosion condition is not considered in the crash test, so the collision coverage is small, and the fuel c...

Abstract

The invention relates to a vehicle fuel oil electrical control method and system, a vehicle and a computer readable medium. The method comprises the steps acquiring the total vehicle speed variable quantity of the vehicle in a current collision process; judging whether the total variation quantity of the vehicle speed is out of a vehicle fuel oil electric control triggering threshold value line ornot; if so, triggering vehicle fuel electric cut-off control, the vehicle fuel oil electrical control triggering threshold line being an elliptic curve established according to a first change speed of the vehicle under the maximum non-triggering working condition of head-on collision, a second change speed of the vehicle under the maximum non-triggering working condition of side collision and a third change speed of the vehicle under the maximum non-triggering working condition of rear collision. The method does not depend on front, side and rear collision algorithms any more; and moreover, the coverage range of the threshold line is enlarged, the control stability is ensured to the maximum extent, the collision safety performance is improved, and complaints of after-sales accidents are reduced.

Example Embodiment

[0096] Based on the first embodiment of the present invention, the second embodiment of the present invention provides a vehicle fuel electrical control system, such as Figure 19 As shown, the system 100 includes:
[0097] a vehicle speed total change obtaining unit 1, configured to obtain the vehicle speed total change when the vehicle has a current collision;
[0098] Trigger judging unit 2, for judging whether the total change of the vehicle speed is outside the triggering threshold line of the vehicle fuel electrical control, if so, triggering the vehicle fuel electrical cut-off control, wherein the vehicle fuel electrical control triggers the threshold line It is an elliptic curve established according to the first change speed of the vehicle when the vehicle has the maximum non-trigger condition of frontal collision, the second change speed of the vehicle when the side collision is the maximum non-trigger condition, and the third change speed of the vehicle when the rear collision is the maximum non-trigger condition.

Example Embodiment

[0099] Based on the second embodiment of the present invention, the third embodiment of the present invention provides a vehicle, including the system described in the second embodiment.
[0100] Based on Embodiment 1 of the present invention, Embodiment 4 of the present invention provides a computer-readable medium on which a computer program is stored, and when the computer program is executed by a processor, implements the steps of the method for electrical control of automobile fuel in Embodiment 1.
