Embodiment 1

[0049] Such as figure 1 Shown is the work flow diagram of a kind of automobile start-stop control method of the present invention, comprises:

[0050] Step S101, in response to when the accuracy state of the battery sensor is a low-accuracy state, it is judged whether the state of the vehicle battery satisfies the preset low-accuracy start-stop condition;

[0051] In step S102, if the state of the battery satisfies the low-precision start-stop condition, the vehicle start-stop function is allowed; otherwise, the vehicle start-stop function is prohibited.

[0052] Specifically, the present invention is mainly applied to electronic control units (Electronic Control Unit, ECU) of automobiles. For example, the engine control unit (Engine Management System, EMS) of a car, the IBS and the EMS communicate and transmit information through a local interconnect network (Local Interconnect Network, LIN) bus. When the accuracy state of the battery sensor is low accuracy, step S101 is tr...

Abstract

The invention discloses an automobile start-stop control method and electronic equipment. The method includes: judging whether the state of the automobile battery satisfies the preset low-precision start-stop condition in response to the low-precision state of the battery sensor accuracy state; if the battery state satisfies the low-precision start-stop condition If the stop condition is met, the car start-stop function is allowed, otherwise the car start-stop function is prohibited. In the present invention, when the battery sensor is low-precision, the start-stop function is not directly prohibited first, and the start-stop action is re-judged by detecting whether the battery state meets the low-precision start-stop condition, which can realize that when the battery sensor is low-precision, still It can realize the function of starting and stopping.

Description

technical field [0001] The invention relates to the technical field related to automobiles, in particular to an automobile start-stop control method and electronic equipment. Background technique [0002] Automobile start-stop technology is the technology of starting the engine by starting and stopping. In the existing start-stop technology, the battery sensor (Intelligent Battery Sensor, IBS) is required to detect the state of charge of the battery. , ISS). Low precision means that the state of charge (State Of Charge, SOC) error of the IBS is greater than a preset value, and the prior art sets the SOC error greater than 15% as the low precision state of the IBS. [0003] However, disconnecting the negative wire of the battery, unplugging the IBS connector, or accumulating IBS errors will all lead to a decrease in the accuracy of the battery sensor. [0004] For example, disconnecting the negative wire of the battery causes the IBS to report low accuracy: When disconnect...
