Description
Technical Field
The invention relates to an internal structure of an automobile, in particular to an automobile control device.
Background
The technical scheme of the traditional hydraulic electronic braking system is composed of an ESC hydraulic regulation module ECU, an electronic braking pressure building module ECU, an EPB electronic parking module ECU, a parking actuator and a CAN bus for mutual communication, wherein the ESC refers to an automobile electronic stabilizing system, the ECU refers to an electronic control unit, and the EPB refers to an electronic parking system. The three control units ECU carry out signal interaction through a CAN bus, and the electronic parking actuator respectively controls the two rear wheels. When the automobile is resident, the automobile stops, the detection signal is transmitted to the electronic parking module ECU, the electronic parking module ECU sends out a parking instruction, and after the electronic parking actuator receives the instruction, the motor is clamped tightly to execute a parking function. When the automobile is started, the electronic parking module ECU sends a parking releasing instruction through a driver key or an accelerator pedal signal, and after the electronic parking actuator receives the instruction, the motor rotates reversely to realize a releasing function. And if the electronic parking module ECU has a fault, the whole parking braking system fails.
The improved hydraulic electronic brake system comprises an ESC (electronic stability control) hydraulic adjusting module ECU, an electronic brake pressure building module ECU, a parking actuator and a CAN bus for mutual communication. The improved solution cancels the integration of the program of the control unit into the electronic brake pressure building module ECU or the ESC hydraulic pressure regulating module ECU by the electronic parking module ECU. There are some control units that directly control the parking actuator. When the automobile is resident, the automobile stops, a detection signal is transmitted to the control unit, one of the ESC hydraulic pressure adjusting module ECU or the electronic braking pressure building module ECU sends a parking instruction, and after the electronic parking actuator receives the instruction, the motor is clamped to execute a parking function. When the automobile is started, a parking releasing instruction is sent by one of an ESC (electronic stability control) hydraulic adjusting module ECU or an electronic brake pressure building module ECU through a key or an accelerator pedal signal of a driver, and after the electronic parking actuator receives the instruction, the motor rotates reversely to realize a releasing function. In a failure mode, when a certain module of an Electronic Control Unit (ECU) or an electronic brake pressure building module of the ESC hydraulic pressure regulating module fails, a parking instruction cannot be sent, and the whole parking brake system fails.
According to the traditional technical scheme, each product is provided with an ECU (electronic control unit), the complexity of wiring harness arrangement is increased, the wiring harnesses are mutually communicated, CAN (controller area network) bus resources are occupied, and the real-time communication effect is influenced. The improved technical scheme has the defect that when the control unit of the electronic braking parking system or the control unit integrating the function fails, the parking function of the whole vehicle is lost.
