Embodiment Construction

[0046] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0047] Aiming at the current car shutdown, if the electronic equipment of the whole vehicle is abnormal, the problem of power loss of the whole vehicle is likely to occur. The invention provides a car shutdown protection system. By detecting the discharge current of the battery, Finally, if the electronic equipment is abnormal, it can cut off the power supply of the battery in time, and send a message through the CAN bus to disconnect the electrical connection of the electronic equipment, avoiding the problem that the vehicle cannot start due to power loss, and improving the safety of the vehicle. And reduce the energy consumption of the car.

[0048] Such as figure 1 As shown, it is a schematic diagram of an a...

Abstract

The invention relates to an automobile starting and stopping protective system and method. The automobile starting and stopping protective system comprises a storage battery, an electric quantity sensor and an automobile body controller which is connected with a CAN bus. The electric quantity sensor is arranged at the output end of the storage battery, is used for detecting the discharge current of the storage battery and is connected with the communication end of the automobile body controller through a LIN bus. When an ignition lock ON gear switch is disconnected, the automobile body controller sends a network dormant message through the CAN bus, so that idle electronic equipment connected with the CAN bus enters the dormant state, and the automobile body controller enters the dormant state after the discharge current of the storage battery is smaller than a first threshold value. After the automobile body controller enters the dormant state, if the discharge current of the storage battery is larger than a second threshold value, constant electricity output by the storage battery is controlled to be disconnected in the set time, and a forced outage message and a failure warning message are sent through the CAN bus. Through the automobile starting and stopping protective system and method, the safety of an automobile can be improved, and the energy consumption of the automobile is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile electronics, in particular to an automobile start-stop protection system and method. Background technique [0002] The electronic configuration of the car is getting higher and higher, which leads to the increase of the quiescent current after the whole vehicle is static. Due to the increase of the electronic configuration, the probability of the abnormal static discharge of the whole vehicle due to some signal abnormalities will also increase. If these abnormal changes of the discharge If the output current is not controlled, it may cause the vehicle to lose power, thereby affecting the starting of the vehicle engine. At the same time, when the vehicle is turned off, some systems must complete a certain function before entering the dormant state. For example, the urea injection in the engine aftertreatment system still needs to work for a period of time after the vehicle is turned off due to t...
