[0027] Such as figure 1 As shown, it is a flow chart of the control method of the vehicle power in the first embodiment of the present invention, the control method is applied to the vehicle controller, including:

[0028] Step 101 , when the current driving state of the car meets the predetermined high power output state and the closing signal sent when the key switch is powered off is received, the duration of the closing signal is monitored.

[0029] In this step, specifically, if the current driving state of the vehicle meets the predetermined high power output state, and the vehicle controller receives the closing signal sent when the key switch is powered off, it monitors the duration of the closing signal. In this way, by monitoring the duration of the shutdown signal, it can be judged whether the operation of powering off the key switch is an abnormal operation, wherein, if the duration of the shutdown signal is greater than the first preset time, it can be determined ...

[0041] Such as image 3 As shown, it is a schematic structural diagram of the control device of the vehicle power in the second embodiment of the present invention. The control device is applied to the vehicle controller, including:

[0042] The monitoring module 301 is used to monitor the duration of the closing signal when the current driving state of the car meets the predetermined high power output state and the closing signal sent when the key switch is powered off is received;

[0043] The first signal sending module 302 is configured to send a control signal for refusing power-off operation within a second preset time when the duration of the shutdown signal is shorter than the first preset time.

[0044] Optionally, the control device further includes: a first monitoring module, configured to monitor the current driving speed of the car; when the current driving speed is greater than a preset speed value, determine that the current driving state of the car conforms to ...

Abstract

The invention provides an automobile power control method and device. The automobile power control method comprises the steps that when the current traveling state of an automobile accords with a preset high-power output state and a shutdown signal sent while a key switch is powered off is received, the duration of the shutdown signal is monitored; and when the duration of the shutdown signal is shorten than a first preset time, a control signal for rejecting power-off operation in a second preset time is sent out. By adoption of the automobile power control method and device, the problem that in the prior art, the automobile loses power suddenly due to misoperation of a key switch by an automobile driver during high-speed traveling of the automobile, and consequentially the driving safety of the automobile is lowered is solved, time is provided for the driver to operate the key switch correctly, and the driving flexibility is improved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an automobile power control method and device. Background technique [0002] When the car needs to stop during high-speed driving, in order to ensure the safety of the members in the car, the car should stop slowly, that is, the car cannot suddenly lose power. However, when the car is running at high speed, if the driver misoperates the key switch, it will easily cause the car to suddenly lose power and reduce the driving safety of the car. Contents of the invention [0003] The object of the present invention is to provide a method and device for controlling the power of an automobile to solve the problem in the prior art that when the automobile is running at high speed, the automobile driver misoperates the key switch, causing the automobile to suddenly lose power and reduce the driving safety of the automobile. [0004] In a first aspect, the present invention provides a control...
