Detailed Description
The embodiment of the vehicle is as follows:
the present embodiment provides a vehicle, such as: a passenger car comprises a car body and a storage battery power-shortage-preventing control system. Wherein, the vehicle body includes: the vehicle body belongs to the conventional technology and is not a protection key, so the embodiment is not described again, and a storage battery power-shortage prevention control system (hereinafter referred to as a control system) is specifically described below.
The control system comprises an electric quantity detection module (corresponding to the IBS electric quantity sensor in the figure 1, and hereinafter referred to as the IBS electric quantity sensor), a key switch gear detection module, an engine running state detection module, a control module and a control signal execution module.
The IBS power sensor is used to detect the remaining power of the battery, and may be a conventional power detection device. The key switch gear detection module is used for detecting the gear (such as ACC gear and ON gear) of a key switch (also called an ignition lock) and outputting the detected gear information. The engine running state detection module is used for detecting the running state of the engine, when the engine runs, the rotating speed is not 0, and when the engine stops running, the rotating speed is 0, so that the engine running state detection module can be engine rotating speed detection equipment and can represent the running state of the vehicle through the rotating speed. The control module realizes the control of the storage battery against power shortage, in the embodiment, the control module is a BCM vehicle body controller, and of course, the control module may also be other controllers, such as a whole vehicle controller or a specially-arranged controller. The control signal execution module is used for executing a control signal of the BCM vehicle body controller, and comprises a power shortage warning unit and a main fire relay K1, wherein the power shortage warning unit is a warning device for sending a warning signal to related personnel, such as a warning lamp, a buzzer or an audible and visual alarm, and the audible and visual alarm is taken as an example in the embodiment; the main fire relay K1 is provided on the power supply line between the battery and the consumer. Of course, the main fire relay K1 could also be replaced by other kinds of control switches, such as power devices.
This control system passes through the gateway and realizes communication, and IBS electric quantity sensor passes through LIN line connection gateway, and key switch keeps off a gear detection module and links to each other with the instrument through the hardwire, and the instrument passes through first CAN line connection gateway, and the state that the ignition lock is located is converted into the CAN message after the instrument is gathered and is sent to the gateway. Of course, the key switch gear detection module can also be directly connected with the gateway instead of the instrument. The engine running state detection module is connected with the gateway through a second CAN line, and the engine running state message is directly sent to the gateway through a CAN message.

Of course, the BCM vehicle body controller can also send the power shortage prevention alarm instruction to a vehicle central control screen, and reminding character information is displayed through the screen.
In addition, the low-power threshold for judging the triggering alarm condition and the low-power threshold for judging the triggering power-off condition can be unequal and are divided into an alarm threshold and a power-off threshold, and the alarm threshold is larger than the power-off threshold. Then, when the ignition lock is in an ACC gear or an ON gear, the engine rotating speed is 0, and the residual electric quantity of the storage battery is lower than a set alarm threshold value, the condition that an alarm is triggered is judged to be met, the BCM vehicle body controller sends an electricity shortage prevention alarm instruction, the electricity shortage prevention alarm instruction is sent to an audible and visual alarm to execute a continuous alarm action, and in the alarm process, an instruction can be interrupted when a key is pulled out or a vehicle is started. The electric quantity of battery reduces gradually, when the ignition lock is in ACC gear or ON gear, the engine speed is 0 and the residual electric quantity of battery is less than the settlement power-off threshold, judge that to satisfy and trigger the power-off condition, then BCM automobile body controller sends out the warning instruction of preventing insufficient power and prevents the instruction of preventing insufficient power, the warning instruction of preventing insufficient power sends audible-visual annunciator, the instruction of preventing insufficient power is sent to main fire relay K1, can have certain order between the warning instruction of preventing insufficient power and the instruction of preventing insufficient power, send out the warning instruction of preventing insufficient power earlier, after carrying out audible-visual alarm for a certain time, send out the instruction of preventing insufficient power again, control main fire relay K1 disconnection, realize the whole car power down, in the power-off process, pull out the key or start the vehicle all can the interrupt instruction.
