Embodiment

[0048] After the key is unlocked, the first power controller 21 and the second power controller 22 wake up, and the vehicle wake-up device 5 sends a signal to other controllers of the vehicle. The ignition switch 1 receives the key insertion signal, and the first power controller 21 and the second power controller 22 recognize that the voltage of the flameout gear is 12V, and the network signal of the power mode is the flameout mode. When the key is turned from the auxiliary power supply gear to the power-on gear, the ignition switch 1 receives the key-in signal, and the power-on power supply voltage output to the first power supply controller 21 and the second power supply controller 22 is 12V, and the first power supply control The controller 21 and the second power controller 22 output to control the power-on power relay, the power-on power relay works, and outputs the power-on power to supply power to the vehicle equipment. The network signal of the power mode is the power-...

Abstract

The invention discloses a redundant control system and method for power supply modes of a complete vehicle. The system includes an ignition switch (1) and a power supply mode control device (2). The power supply mode control device includes a first power supply controller (21) and a second power supply controller (21). Power supply controller (22); the output terminal of the ignition switch is connected with the input terminal of the first power supply controller and the second power supply controller, and the output terminals of the first power supply controller and the second power supply controller are respectively connected with the auxiliary power supply relay (3 ), the power-on / starting relay (4) and the vehicle wake-up device (5); the first power controller and the second power controller are connected to the controller through the vehicle bus. The present invention uses dual controllers to control the power supply mode, simultaneously controls the network signal to realize the redundant control of the power supply mode, thereby preventing the failure of the power distribution function, ensuring the effective control and reliable output of the power distribution, and taking into account the safety requirements. And can be developed at low cost.

Description

technical field [0001] The invention relates to a vehicle power supply distribution system and method, in particular to a vehicle power supply mode redundancy control system and method. Background technique [0002] At present, most OEMs adopt the traditional power supply mode, and identify and output four power supply modes through the ignition switch mechanical key form: flameout, auxiliary power supply, power-on power supply, and starting power supply mode. Usually, the ignition switch has its own load. However, this kind of power mode switching is relatively simple, and it is only switched according to the state of the key, and power mode management and control cannot be performed, which will cause some remote control functions of the vehicle to be unable to be realized. [0003] With the popularity of keyless entry and start vehicles, most OEMs control the output of four power modes through keyless start buttons and relays. Since a single controller performs power cont...
