Problems solved by technology

If the power of the vehicle controller is turned off during KEYOFF, the vehicle controller will be re-initialized every time it is powered on, and it will take at least 400ms, which will seriously affect the normal startup time of the vehicle; and if When KEYOFF is still used, the vehicle controller is still working normally, because of its large quiescent current, it will greatly consume the power of the car battery, and even consume the power of the battery so that the car cannot start normally.

Embodiment 1

[0024] Such as figure 1 As shown, the method of the hybrid vehicle controller of the present embodiment includes the following steps:

[0025] A: In the normal working mode, when the key is switched from the on state to the off state and kept for a certain period of time, the vehicle controller will turn off the modules except the specific module, and set the cycle flag to FALSE, from the normal working mode Switch to sleep mode, the above time is generally about 1 millisecond;

[0026] B: The vehicle controller controls the timer to start timing;

[0027] C: When the vehicle controller detects that the key is switched from the off state to the on state, the vehicle controller sets the cycle flag to TRUE, and switches from the sleep mode to the normal working mode;

[0028] D: When the vehicle controller receives the signal that the timing of the timer is over, the vehicle controller first resets the timer, then performs its own function check, and then checks out the cycle ...

Abstract

The invention aims at providing a control method of a whole car controller of a hybrid electric car which saves electricity and can lead the car to start fast. The control method comprises a normal work mode and a sleep mode; under the normal work mode, when a key is switched into an off state from an on state and is kept for a certain time; the whole car controller is switched to the sleep mode from the normal work mode; under the sleep mode, in the whole car controller, only specific modules are kept to work, the rest of modules are closed; and when a waking condition is met, the whole car controller enters the normal work mode. The control method of the whole car controller of the hybrid electric car reduces the electric energy consumption of the whole car controller of the hybrid electric car by setting the sleep mode, simultaneously avoids electrifying initiation of software each time, reduces the waiting time of starting of the hybrid electric car and has important significance for improving success rate of cold starting of the hybrid electric car.

Description

technical field [0001] The invention belongs to the technical field of hybrid electric vehicle control, and in particular relates to a control method of a vehicle controller. Background technique [0002] With the development of science and technology, more and more electronic devices and equipment are applied to the automotive field. The vehicle controller is one of the important equipment of the automobile, and is responsible for controlling other equipment. If the power of the vehicle controller is turned off during KEYOFF, the vehicle controller will be re-initialized every time it is powered on, and it will take at least 400ms, which will seriously affect the normal startup time of the vehicle; and if When KEYOFF is still used, the vehicle controller is still working normally. Because of its large static current, it will greatly consume the power of the car battery, and even consume the battery power so that the car cannot start normally. Contents of the invention ...
