Embodiment Construction

[0021] Such as figure 1 As shown, the current sensor, angle sensor, and trunk switch are connected to the signal input end of the main control chip through the input interface circuit (input signal circuit), and the signal output end of the main control chip is connected to the trunk lock through the output interface circuit (output signal circuit) Device, alarm horn, motor drive module, main control chip and CAN module communication connection. The main control chip controls the 5V sensor power supply chip and the 12V regulated power supply chip through the 5V power supply controlled circuit and the 12V power supply controlled circuit respectively. The current sensor and angle sensor are powered by the 5V sensor power chip, and the trunk locker, alarm horn and DC motor are powered by the 12V regulated power chip. The main control chip adopts Infineon XC800, the 12V regulated power chip adopts Infineon TLE42XX, the 5V sensor power chip adopts TLE42XX, and the motor drive chip...

Abstract

The invention relates to a low-power consumption control system of an automobile electric trunk system and a control method thereof. The signal input end of a main control chip is connected with a current sensor, an angle sensor and a trunk switch; the signal output end of the main control chip is connected with a trunk locking mechanism, an alarming horn and a motor drive module; and the main control chip is connected with a CAN module by communication. After the electric trunk system is electrified for a time or is closed for a time, if the main control chip does not receive any switch input signal, the system enters a low-power consumption mode, wherein the low-power consumption mode comprises a low-speed mode and an idle mode. In the low-speed mode, the clock frequency of the main control chip is reduced; in the idle mode, an externally arranged module of the main control chip is shielded and then the kernel clock of the main control chip CPU is ended; and in the low-power consumption mode, the system enters the low-speed mode firstly, and after the system runs for a time in the low-speed mode and if the main control chip does not receive any switch input signal, the system enters the idle mode.

Description

technical field [0001] The invention relates to a low power consumption control system of an electric trunk system of an automobile and a control method thereof. Background technique [0002] Safety, energy saving, environmental protection, intelligence and informatization are the development trends of automobiles. With the rapid development of automotive electronics, more and more automotive electrical appliances such as electronic controllers, sensors, and actuators are integrated on the car. While these electronic and electrical equipment have improved people's safety and comfort, they have also brought about the problem of automobile power consumption. There are more and more electrical equipment, and the electrical load is getting bigger and bigger, and many equipment are connected to the battery, but in many cases do not need to work, which brings a lot of waste of energy. [0003] Car electric luggage is a requirement for improving car comfort and humanization. Due...
