Embodiment 1

[0035] like figure 1 As shown, the vehicle front hood management system includes an acquisition unit, a control unit, a range extender control unit, a display unit and an alarm unit. The control unit and display unit are integrated on the vehicle MCU.

[0036] The collection unit is used to collect the status of the front hood, and also used to collect the status of the car. These all belong to the prior art, such as collecting the state of the front hood lock to feed back the state of the front hood, which will not be repeated here.

[0037] The control unit analyzes whether there is any abnormality according to the state of the front hood and the state of the car;

[0038] The range extender control unit is used to control the state of the range extender;

[0039] If the state of the front hood is open, and the state of the car is parked, the control unit sends a prompt signal to the range extender control unit, and after receiving the prompt signal, the range extender co...

Embodiment 2

[0049] Different from Embodiment 1, in this embodiment, the emergency plan is stored in the control unit, and when the control unit controls the display unit to display the alarm information, it also controls the display unit to display the emergency plan.

[0050] Under special circumstances, such as when driving on a road that is inconvenient to stop and get off, some people will appear confused and overwhelmed. By setting up an emergency plan, the people in the car can know what to do to relieve the risk (such as reduce speed, search for an emergency stop, etc.).

Embodiment 3

[0052] The difference from Embodiment 1 is that in this embodiment, when the range extender control unit controls the start of the range extender without fuel injection, based on the angle of protection, the range extender control unit adjusts the operating speed of the range extender in time domain, so that the range extender The frequency of the programmer noise changes. In this way, it is also possible to avoid the noise of a single rotational speed being affected by the environment, resulting in the occurrence of acoustic frequency coverage.

Abstract

The invention belongs to the technical field of vehicle management, and particularly relates to a vehicle front engine hood management system and method, and the system comprises an acquisition unit which is used for acquiring the state of a front engine hood and also used for acquiring the state of a vehicle; a control unit used for analyzing whether abnormality exists or not according to the state of the front engine hood and the state of the vehicle; a range extender control unit used for controlling the state of the range extender; wherein if the state of the front engine hood is an open state and the state of the automobile is a parking state, the control unit sends a prompt signal to the range extender control unit, and after receiving the prompt signal, the range extender control unit controls the range extender to be started and not to spray oil. By using the system, related accidents caused by the front engine hood can be stably reduced.

Description

technical field [0001] The invention belongs to the technical field of vehicle management, in particular to a vehicle front hood management system and method. Background technique [0002] The front hood of the car is set on the head of the car and is an indispensable part of the car. The main function of the front hood is to protect the safety of various parts in the engine compartment and fully protect the normal operation of the vehicle. When the structure in the front hood is overhauled, relevant operations can be performed by opening the front hood. [0003] However, if the front hood is opened when it is not necessary, such as when the vehicle is parked, the vehicle is in a high-voltage state, and the electric circuit in the car makes maintenance personnel have the risk of high-voltage electric shock. If the light of the car light is used for prompting, the prompting effect is not very satisfactory in a place with sufficient light. [0004] Therefore, there is a need...
